feat(context): Standardize context system with navigation, frontmatter, and MVI compliance (#209)

* feat: add OAC package refactor context file

- Add comprehensive feature context for OAC package refactor
- Document multi-IDE support architecture
- Define community component registry (shadcn-like)
- Outline flexible configuration system
- Detail context file location flexibility
- Define 7-phase implementation plan
- Include CLI commands reference
- Add community publishing guidelines

* docs: add OAC refactor quick start guide

- Add quick reference for Phase 1 implementation
- Include project structure and file locations
- Document configuration schema and defaults
- Add testing strategy and validation steps
- Include development workflow
- Reference all related resources

* feat: add critical user approval and context resolution systems

CRITICAL FEATURES ADDED:

1. User Approval & YOLO Mode
   - Default: Interactive approval for all file operations
   - Always asks: local vs global install
   - Confirms before overwriting files
   - Shows diffs and file details
   - YOLO mode (--yolo): Skip confirmations, auto-resolve, report at end
   - Conflict strategies: ask, skip, overwrite, backup, yolo
   - Safety: backups, git detection, rollback support, audit log

2. Context Resolution System
   - Layered context resolution (6 priority levels)
   - Project override (.oac/context/) - highest priority
   - Project context (.opencode/context/)
   - IDE context (.cursor/, .claude/)
   - Project docs (docs/)
   - User global (~/.config/oac/context/)
   - OAC official (~/.config/oac/official/) - lowest priority
   - Smart resolution based on agent location (global vs local)
   - preferLocal config option
   - Context merging strategies
   - CLI commands for context management
   - Environment variable overrides
   - Validation and fallback support

3. Enhanced CLI Commands
   - All commands support --yolo, --dry-run, --local, --global
   - Context management: resolve, list, validate, override, sync
   - Detailed help and examples
   - Global flags for all commands

This ensures users maintain full control over their projects while
supporting both local and global workflows with intelligent context
resolution.

* feat: add component creation wizard and IDE feature parity system

NEW FEATURES:

1. Interactive Component Creation
   - oac create (interactive wizard)
   - Create agents, skills, contexts, plugins, commands, tools
   - Template system for scaffolding
   - Auto-generate tests and boilerplate
   - Multi-IDE compatibility selection
   - Size optimization options

2. IDE Feature Parity & Capacity Management (CRITICAL)
   - Feature support matrix for all IDEs
   - OpenCode/Claude Code: Full support (all features)
   - Cursor: Limited (single file, no skills/plugins, 100KB limit)
   - Windsurf: Partial support
   - Adaptive installation based on IDE capabilities
   - Automatic feature filtering and warnings
   - Component merging for single-file IDEs (Cursor)
   - Capacity warnings and optimization
   - IDE-specific profiles

3. Enhanced CLI Commands
   - oac create [type] - Component creation wizard
   - oac templates - List available templates
   - oac compatibility <ide> - Check IDE compatibility
   - oac ides - List supported IDEs with features
   - oac ide info <ide> - Show IDE capabilities
   - oac optimize --for <ide> - Optimize for specific IDE
   - oac validate --ide <ide> - Validate IDE installation

4. Smart Installation
   - Detects IDE capabilities
   - Warns about unsupported features
   - Auto-filters components
   - Merges agents for Cursor
   - Embeds contexts for limited IDEs
   - Monitors file size limits
   - Suggests IDE-specific profiles

This ensures users can easily create components and OAC gracefully
handles different IDE capabilities with clear warnings and automatic
optimization.

* docs: add critical feedback from parallel agent review

CRITICAL FINDINGS:

Security Gaps (BLOCKER):
- No component signing or verification
- No malware/secret scanning
- No permission system
- Action: Add security layer in Phase 1

Missing Features (CRITICAL):
- Discovery (browse, search, trending)
- Lockfile for reproducibility
- Version conflict management
- Interactive onboarding
- Progress indicators
- Auto-detection for local/global

Approaches to Rethink:
- Context merging → Use composition instead
- Always asking local/global → Auto-detect with smart defaults
- Cursor agent merging → Router pattern instead

Repository Structure:
- Recommended: Monorepo with pnpm workspaces
- Packages: core, adapters, registry, security, cli
- Benefits: Shared deps, atomic commits, easier testing

Community Workflow:
- Component submission process
- Automated security scanning
- Manual review for verification
- Moderation system

Updated Priorities:
- v1.0 MVP: Add 6 critical features (discovery, lockfile, security, etc.)
- v1.1: Plugin system, workspace support, marketplace
- v2.0: Enterprise features

Documentation Needs:
- Quick Start (5-minute guide)
- CLI Reference (auto-generated)
- Recipes/Cookbook
- Component Creation Guide
- Migration Guide

Overall: Plan is 80% solid, needs 20% critical additions before Phase 1

* feat: add comprehensive agent customization and preset system

CRITICAL FEATURE: Agent Customization & Personal Presets

Problem:
- Users want to customize agent prompts for their workflow
- Users want to save personal configurations
- Updates shouldn't overwrite customizations
- Need easy way to view and edit agents

Solution: Multi-Layer Customization System

Layer 1: View Agent Configuration
- oac show agent:openagent (view in pager)
- oac edit agent:openagent (open in editor)
- oac config show agent:openagent (config only)
- oac export agent:openagent (export to file)

Layer 2: Create Personal Preset
- oac customize agent:openagent (create preset)
- Copies to ~/.config/oac/presets/agents/
- Links to base agent for updates
- Tracks customizations in metadata

Layer 3: Edit Personal Preset
- oac edit preset:my-openagent (edit in $EDITOR)
- oac customize preset:my-openagent --interactive (wizard)
- Auto-backup on save
- Track modification history

Layer 4: Use Personal Preset
- oac use preset:my-openagent (activate)
- oac use preset:my-openagent --global (set default)
- oac presets list --active (show active)
- Switch between presets and base agents

Layer 5: Update Management (CRITICAL)
- Smart update detection for base agents
- Merge strategies: manual, auto-base, auto-merge, locked
- Conflict resolution with user prompts
- Show diffs before merging
- Auto-backup before updates
- Preserve user customizations by default

Layer 6: Preset Sharing
- oac export preset:my-openagent (export)
- oac import preset ./preset.md (import)
- oac share preset:my-openagent (share with team)
- oac publish preset:my-openagent (publish to community)

Layer 7: In-Place Editing (Advanced)
- oac edit agent:openagent --in-place (risky, warns user)
- Creates backup before editing
- Warns that updates will overwrite
- Recommends preset creation instead

Update Strategies:
- manual: User reviews every update
- auto-base: Auto-update base, keep preset unchanged
- auto-merge: Auto-merge, prompt on conflicts
- locked: Never update base

Configuration:
- Preset metadata (.presets.json)
- Update strategies per preset
- Merge conflict resolution
- Backup management
- Warning preferences

Edge Cases Handled:
- In-place edits before updates
- Multiple updates behind
- Multiple presets for same base
- Preset conflicts with IDE
- Deleted base agent

Best Practices:
- Always create presets (safest)
- Document customizations
- Review updates before merging
- Keep backups
- Use descriptive names

This ensures users can safely customize agents without fear of
losing changes on updates, while still benefiting from base agent
improvements.

FINAL REVIEW COMPLETE:

Overall Assessment: CONDITIONAL GO ✅⚠️
Confidence Level: 85% (High, with conditions)
Success Probability: 75% (with modifications)

Key Strengths:
✅ Exceptional user research (16,000+ lines, 4 personas)
✅ Clear technical architecture (monorepo, TypeScript, Zod)
✅ Security-first mindset (signing, scanning, verification)
✅ Realistic scope management (v1.0 vs v1.1 vs v2.0)
✅ Comprehensive feature coverage

Critical Gaps Identified:
❌ Discovery/Onboarding not in Phase 1 (but P0 in scenarios)
❌ Lockfile not in Phase 2 (but critical for teams)
❌ Security Pipeline not detailed in phases
❌ Progress UI not in Phase 1 (but needed for UX)
❌ Auto-detection not in Phase 1 (but reduces friction)

Conditions for Go:
1. Add discovery/onboarding to Phase 1 (+3 days)
2. Add lockfile to Phase 2 (+2 days)
3. Add security pipeline to Phase 1 (+2 days)
4. Add progress UI to Phase 1 (+1 day)

+
+## Workflow Execution
+
+### Step 1: Initialize Workflow
+
+**Input**: Feature request with requirements
+
+**Process**:
+1. Create session directory: `.tmp/sessions/{timestamp}-{feature}/`
+2. Initialize stage tracking:
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts init {feature}
+   ```
+3. Load context and standards
+4. Create session context bundle
+
+**Output**: Initialized workflow with stage tracking
+
+---
+
+### Step 2: Execute Stage Sequence
+
+**For each stage (1-8)**:
+
+1. **Validate Prerequisites**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts validate {feature} {stage}
+   ```
+   - Check previous stage completed
+   - Verify required inputs exist
+   - Validate gating criteria met
+
+2. **Execute Stage Activities**
+   - Follow stage-specific process
+   - Delegate to appropriate agents
+   - Monitor progress
+   - Handle errors
+
+3. **Validate Stage Completion**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts complete {feature} {stage}
+   ```
+   - Verify all outputs created
+   - Check validation criteria met
+   - Confirm ready for next stage
+
+4. **Update Stage Status**
+   - Mark stage complete in tracking
+   - Update session context
+   - Log stage completion
+
+5. **Transition to Next Stage**
+   - Validate transition gate
+   - Prepare inputs for next stage
+   - Continue workflow
+
+---
+
+### Step 3: Handle Stage Failures
+
+**If stage validation fails**:
+
+1. **Detect Failure**
+   - Validation criteria not met
+   - Required outputs missing
+   - Critical errors occurred
+
+2. **Assess Impact**
+   - Determine if recoverable
+   - Identify root cause
+   - Check if rollback needed
+
+3. **Execute Rollback (if needed)**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts rollback {feature} {stage}
+   ```
+   - Revert stage changes
+   - Restore previous state
+   - Clean up partial outputs
+
+4. **Report Failure**
+   - Document failure details
+   - Provide recovery recommendations
+   - Update stage status to "failed"
+
+5. **Retry or Abort**
+   - Retry stage with fixes
+   - Or abort workflow if unrecoverable
+
+---
+
+### Step 4: Monitor Workflow Progress
+
+**Throughout execution**:
+
+1. **Check Stage Status**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts status {feature}
+   ```
+
+2. **Track Progress**
+   - Current stage
+   - Completed stages
+   - Remaining stages
+   - Overall progress percentage
+
+3. **Identify Blockers**
+   - Failed validations
+   - Missing prerequisites
+   - Unresolved issues

+
+## Gating Rules
+
+### Rule 1: Sequential Stage Execution
+
+**Enforcement**: Cannot skip stages
+
+**Validation**:
+- Stage N requires Stage N-1 complete
+- No parallel stage execution
+- Must follow defined sequence
+
+**Exception**: None (strict sequential)
+
+---
+
+### Rule 2: Prerequisite Completion
+
+**Enforcement**: Previous stage must be complete
+
+**Validation**:
+- Check stage status = "completed"
+- Verify all outputs exist
+- Confirm validation criteria met
+
+**Exception**: None (strict prerequisite)
+
+---
+
+### Rule 3: Output Validation
+
+**Enforcement**: Stage outputs must meet criteria
+
+**Validation**:
+- All required outputs created
+- Outputs pass validation checks
+- Quality standards met
+
+**Exception**: Manual override with justification (logged)
+
+---
+
+### Rule 4: Integration Point Validation
+
+**Enforcement**: Contracts must exist before implementation
+
+**Validation**:
+- Stage 5 (Contract Definition) complete before Stage 6 (Execution)
+- All integration points have contracts
+- Contracts validated against architecture
+
+**Exception**: None (critical for parallel execution)
+
+---
+
+### Rule 5: Rollback Safety
+
+**Enforcement**: Failed stages must be recoverable
+
+**Validation**:
+- Stage changes tracked
+- Rollback procedure defined
+- Previous state restorable
+
+**Exception**: Stage 8 (Release) — rollback requires deployment rollback
+
+---
+
+## Error Handling
+
+### Stage Validation Failure
+
+**Scenario**: Stage validation criteria not met
+
+**Response**:
+1. Log validation failure details
+2. Mark stage status as "failed"
+3. Provide specific failure reasons
+4. Recommend corrective actions
+5. Do NOT proceed to next stage
+
+**Example**:
+```
+Stage 4 (Task Breakdown) FAILED
+
+Validation Errors:
+- Task dependency cycle detected: 03 → 05 → 03
+- Subtask 07 missing acceptance criteria
+- Parallel batch 2 has deliverable conflicts
+
+Recommendation: Fix dependency cycle and add missing criteria before proceeding.
+```
+
+---
+
+### Agent Delegation Failure
+
+**Scenario**: Delegated agent fails to complete
+
+**Response**:
+1. Capture agent error details
+2. Assess if retry possible
+3. Retry with fixes (up to 3 attempts)
+4. If retry fails, mark stage failed
+5. Provide recovery recommendations
+
+**Example**:
+```
+BatchExecutor delegation FAILED
+
+Error: Task 05 failed validation (missing tests)
+
+Retry 1/3: Re-executing task 05 with test requirement emphasized
+```
+
+---
+
+### Rollback Execution
+
+**Scenario**: Stage needs to be rolled back
+
+**Process**:
+1. **Identify Rollback Scope**
+   - Which stage to rollback
+   - What changes to revert
+   - What state to restore
+
+2. **Execute Rollback**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts rollback {feature} {stage}
+   ```
+   - Delete stage outputs
+   - Restore previous state
+   - Update stage status to "pending"
+
+3. **Verify Rollback**
+   - Confirm state restored
+   - Validate no artifacts remain
+   - Check system consistency
+
+4. **Log Rollback**
+   - Document rollback reason
+   - Record what was reverted
+   - Note lessons learned
+
+---
+
+### Workflow Abortion
+
+**Scenario**: Unrecoverable failure, must abort
+
+**Process**:
+1. **Assess Abort Necessity**
+   - Multiple stage failures
+   - Critical blocker identified
+   - Requirements changed significantly
+
+2. **Execute Abort**
+   ```bash
+   npx ts-node .opencode/skill/task-management/scripts/stage-cli.ts abort {feature}
+   ```
+   - Mark workflow as "aborted"
+   - Document abort reason
+   - Preserve work for analysis
+
+3. **Cleanup**
+   - Archive partial work
+   - Update session status
+   - Notify stakeholders
+
+---
+
+## Integration with Existing System
+
+### TaskManager Integration
+
+**Stage 4 (Task Breakdown)**:
+```javascript
+// Delegate to TaskManager
+task(
+  subagent_type="TaskManager",
+  description="Break down {feature} into atomic tasks",
+  prompt="Create task breakdown for {feature}.
+         
+         Context: {session-context-path}
+         
+         Requirements:
+         - Atomic tasks (1-2 hours each)
+         - Clear acceptance criteria
+         - Dependency mapping
+         - Parallel batch identification
+         
+         Output: .tmp/tasks/{feature}/ with task.json and subtask_NN.json files"
+)
+```
+
+---
+
+### BatchExecutor Integration
+
+**Stage 6 (Parallel Execution)**:
+```javascript
+// For each parallel batch
+task(
+  subagent_type="BatchExecutor",
+  description="Execute Batch {N} for {feature}",
+  prompt="Execute parallel batch {N} for {feature}.
+         
+         Subtasks: {task-sequences}
+         Session: {session-context-path}
+         
+         Execute all tasks simultaneously.
+         Wait for ALL to complete.
+         Report batch completion status."
+)
+```
+
+---
+
+### Session Context Integration
+
+**Throughout workflow**:
+
+Update `.tmp/sessions/{timestamp}-{feature}/context.md`:

+## Principles
+
+- **Sequential stages**: No skipping, strict order enforcement
+- **Validation gates**: Every stage must pass validation before proceeding
+- **Rollback safety**: Failed stages can be reverted to previous state
+- **Agent coordination**: Delegate to specialized agents for each stage
+- **Progress tracking**: Continuous monitoring and status updates
+- **Error handling**: Graceful failure handling with recovery options
+- **Learning capture**: Document insights for continuous improvement
+
+---
+
+## Quality Standards
+
+- Validate prerequisites before every stage transition
+- Enforce gating rules strictly (no exceptions without justification)
+- Track all stage changes for rollback capability
+- Provide clear error messages with recovery recommendations
+- Update session context continuously
+- Document all stage outputs and validation results
+- Capture learnings throughout workflow

+
+## 🔍 ContextScout — Your First Move
+
+**ALWAYS call ContextScout before creating any ADR.** This is how you get the project's documentation standards, ADR formatting conventions, architectural patterns, and decision-making guidelines.
+
+### When to Call ContextScout
+
+Call ContextScout immediately when ANY of these triggers apply:
+
+- **Before creating any ADR** — you need project-specific conventions
+- **You need ADR format standards** — structure, sections, naming
+- **You need architectural patterns** — understand existing decisions
+- **You're updating existing ADRs** — load standards to maintain consistency
+
+### How to Invoke
+
+```
+task(subagent_type="ContextScout", description="Find ADR standards", prompt="Find ADR formatting standards, documentation conventions, architectural patterns, and decision-making guidelines for this project. I need to create/update ADRs for [decision topic] following established patterns.")
+```
+
+### After ContextScout Returns
+
+1. **Read** every file it recommends (Critical priority first)
+2. **Study** existing ADR examples — match their style and format
+3. **Apply** formatting, structure, and linking standards to your ADRs
+
+---
+# OpenCode Agent Configuration
+# Metadata (id, name, category, type, version, author, tags, dependencies) is stored in:
+# .opencode/config/agent-metadata.json
+
+---
+
+## Workflow
+
+### Step 1: Load Context
+
+**ALWAYS do this first.** Call ContextScout to discover:
+- ADR formatting standards
+- Documentation conventions
+- Architectural patterns
+- Existing ADRs to reference
+
+```
+task(subagent_type="ContextScout", description="Find ADR context", prompt="Find ADR standards, architectural patterns, and existing decision records. I need to create an ADR for [decision topic].")
+```
+
+### Step 2: Capture Decision Context
+
+Document the problem or need that triggered this decision:
+
+- **What** is the architectural challenge or question?
+- **Why** does this decision need to be made now?
+- **Who** is affected by this decision?
+- **When** does this need to be implemented?
+
+### Step 3: Document Alternatives
+
+List ALL alternatives considered, including:
+
+- **Option 1**: Description, pros, cons
+- **Option 2**: Description, pros, cons
+- **Option 3**: Description, pros, cons
+- **Why rejected**: Clear rationale for each rejected option
+
+**RULE**: Never document a decision without alternatives. If only one option was considered, document why other options weren't viable.
+
+### Step 4: Record Decision
+
+State the chosen approach clearly and concisely:
+
+- **What** was decided
+- **Why** this option was chosen
+- **How** it will be implemented
+- **When** it takes effect
+
+### Step 5: Analyze Consequences
+
+Document both positive and negative consequences:
+
+**Positive**:
+- Benefits gained
+- Problems solved
+- Capabilities enabled
+
+**Negative**:
+- Trade-offs accepted
+- Constraints introduced
+- Technical debt incurred
+
+### Step 6: Link to Context
+
+Connect the ADR to relevant project elements:
+
+- **Tasks**: Link to task IDs implementing this decision
+- **Bounded Contexts**: Specify which domains are affected
+- **Related ADRs**: Reference superseded or related decisions
+- **Modules**: List affected code modules
+
+### Step 7: Create ADR File
+
+Generate the ADR markdown file in `docs/adr/` directory:
+
+**Naming Convention**: `{seq}-{kebab-case-title}.md`
+
+Examples:
+- `001-use-jwt-authentication.md`
+- `002-postgresql-for-primary-database.md`
+- `003-microservices-architecture.md`
+
+**File Structure**:
+```markdown
+# {seq}. {Title}
+
+**Status**: {proposed|accepted|deprecated|superseded}
+
+**Date**: {YYYY-MM-DD}
+
+**Context**: {bounded_context} | **Module**: {module}
+
+**Related Tasks**: {task-ids}
+
+**Related ADRs**: {adr-ids}
+
+---
+
+## Context
+
+{Problem statement and background}
+
+## Decision
+
+{What was decided and why}
+
+## Alternatives Considered
+
+### Option 1: {Name}
+- **Pros**: {benefits}
+- **Cons**: {drawbacks}
+- **Why rejected**: {rationale}
+
+### Option 2: {Name}
+- **Pros**: {benefits}
+- **Cons**: {drawbacks}
+- **Why rejected**: {rationale}
+
+## Consequences
+
+### Positive
+- {benefit 1}
+- {benefit 2}
+
+### Negative
+- {trade-off 1}
+- {trade-off 2}
+
+## Implementation Notes
+
+{Any specific guidance for implementation}
+```
+
+### Step 8: Update ADR Index
+
+If `docs/adr/README.md` exists, update it with the new ADR:
+
+```markdown
+## Active ADRs
+
+- 001 - Use JWT Authentication (example: 001-use-jwt-authentication.md)
+- 002 - PostgreSQL for Primary Database (example: 002-postgresql-for-primary-database.md)
+- 003 - New Decision Title (example: 003-new-decision-title.md)
+```
+
+---
+
+## ADR Status Lifecycle
+
+### proposed
+- Decision is being considered
+- Alternatives are being evaluated
+- Stakeholder input is being gathered
+
+### accepted
+- Decision has been approved
+- Implementation can proceed
+- This is the current standard
+
+### deprecated
+- Decision is no longer recommended
+- Existing implementations may remain
+- New work should not follow this pattern
+
+### superseded
+- Decision has been replaced by a newer ADR
+- Link to the superseding ADR
+- Existing implementations should migrate
+
+**Status Change Format**:
+```markdown
+**Status**: superseded by ADR-007 (example: 007-new-approach.md)
+
+**Superseded Date**: 2026-03-15
+```
+
+---
+
+## Linking ADRs to Tasks
+
+When creating ADRs from task context, include task references:
+
+```json
+{
+  "related_adrs": [
+    {
+      "id": "ADR-003",
+      "path": "docs/adr/003-jwt-authentication.md",
+      "title": "Use JWT for stateless authentication",
+      "decision": "JWT with RS256, 15-min access tokens, 7-day refresh tokens"
+    }
+  ]
+}
+```
+
+When creating tasks that implement ADRs, reference them:
+
+```markdown
+**Related ADRs**: ADR-003 (example path: ../../docs/adr/003-jwt-authentication.md)
+
+**Implementation Constraints**:
+- Follow JWT signing approach from ADR-003
+- Use RS256 algorithm as specified
+- Implement 15-minute access token expiry
+```
+
+---
+
+## Bounded Context Integration
+
+ADRs should specify which bounded contexts they affect:
+
+```markdown
+**Context**: authentication, authorization
+
+**Affected Modules**:
+- `@app/auth`
+- `@app/user`
+- `@app/api-gateway`
+```
+
+This enables:
+- Context-specific decision tracking
+- Impact analysis for changes
+- Domain-driven design alignment
+
+---
+
+## What NOT to Do
+
+- ❌ **Don't skip ContextScout** — creating ADRs without standards = inconsistent records
+- ❌ **Don't omit alternatives** — decisions without alternatives lack justification
+- ❌ **Don't use verbose templates** — lightweight format only (5 sections max)
+- ❌ **Don't skip consequences** — every decision has trade-offs
+- ❌ **Don't forget status** — every ADR needs a clear status
+- ❌ **Don't create orphan ADRs** — always link to tasks and contexts
+- ❌ **Don't modify non-ADR files** — only create/edit files in docs/adr/
+
+---
+
+## Quality Standards
+
+### Concise
+- ADRs should be scannable in <2 minutes
+- Use bullet points, not paragraphs
+- Focus on "why" not "how"
+
+### Complete
+- All 5 sections present (Title, Status, Context, Decision, Consequences)
+- At least 2 alternatives documented
+- Both positive and negative consequences listed
+
+### Connected
+- Links to related tasks
+- References to bounded contexts
+- Cross-references to related ADRs
+
+### Current
+- Status reflects reality
+- Superseded ADRs link to replacements
+- Dates are accurate
+
+---

+- Need to identify bounded contexts before task breakdown
+- Complex domain logic requires aggregate/entity modeling
+- Module boundaries are unclear or need formalization
+- Feature involves cross-context integration
+- Need to establish architectural constraints before implementation
+
+**Do NOT use ArchitectureAnalyzer when:**
+- Feature is purely technical (no domain logic)
+- Single, well-defined module with clear boundaries
+- Simple CRUD operations with no complex domain rules
+- Architecture is already well-defined and documented
+
+---
+
+## Workflow
+
+### Step 1: Receive Feature Request
+
+The orchestrator provides:
+- Feature description and objectives
+- Business requirements and use cases
+- Existing codebase context (if available)
+- Session context path (optional)
+
+Example prompt from orchestrator:
+```
+Analyze the architecture for feature "Order Management System":
+
+Requirements:
+- Users can create, modify, and cancel orders
+- Orders contain line items with products and quantities
+- Payment processing integration required
+- Inventory must be reserved when order is placed
+- Order status tracking (pending, confirmed, shipped, delivered, cancelled)
+- Email notifications on status changes
+
+Identify:
+- Bounded contexts
+- Module boundaries
+- Aggregates and entities
+- Domain events
+- Context relationships
+
+Output: contexts.json and module-briefs/
+```
+
+### Step 2: Load Context (ContextScout)
+
+**ALWAYS call ContextScout** to discover relevant architectural patterns and domain modeling guides:
+
+```javascript
+task(
+  subagent_type="ContextScout",
+  description="Find DDD and architecture context",
+  prompt="Find context files for Domain-Driven Design patterns, bounded context identification, aggregate design, and module boundary definition. I need guidance on DDD tactical patterns (aggregates, entities, value objects, domain events) and strategic patterns (bounded contexts, context mapping)."
+)
+```
+
+Load recommended files, focusing on:
+- DDD pattern guides
+- Existing bounded context documentation
+- Module structure conventions
+- Domain modeling standards
+
+### Step 3: Domain Analysis
+
+**Analyze the feature requirements** to identify:
+
+#### 3.1 Business Capabilities
+- What business problems does this solve?
+- What are the core use cases?
+- Who are the actors/users?
+- What are the business rules and invariants?
+
+#### 3.2 Domain Concepts
+- What are the key nouns (potential entities)?
+- What are the key verbs (potential domain events)?
+- What are the business processes/workflows?
+- What are the domain-specific terms (ubiquitous language)?
+
+#### 3.3 Data Ownership
+- What data does each capability own?
+- What are the transactional boundaries?
+- What data is shared vs. duplicated?
+- What are the consistency requirements?
+
+### Step 4: Bounded Context Identification
+
+**Identify bounded contexts** using these criteria:
+
+#### Context Boundaries
+A bounded context should:
+- Own a cohesive set of business capabilities
+- Have clear transactional boundaries
+- Use consistent ubiquitous language
+- Be independently deployable (ideally)
+- Have minimal coupling with other contexts
+
+#### Common Context Patterns
+- **Core Domain**: Unique business differentiator (e.g., "Order Fulfillment")
+- **Supporting Domain**: Necessary but not differentiating (e.g., "User Management")
+- **Generic Domain**: Common across industries (e.g., "Notification", "Authentication")
+
+#### Example Analysis
+For "Order Management System":
+```
+Bounded Contexts Identified:
+1. Order Management (Core Domain)
+   - Owns: Orders, Line Items, Order Status
+   - Capabilities: Create order, modify order, cancel order, track status
+   - Transactional boundary: Order aggregate
+
+2. Inventory (Supporting Domain)
+   - Owns: Products, Stock Levels, Reservations
+   - Capabilities: Reserve stock, release stock, check availability
+   - Transactional boundary: Product aggregate
+
+3. Payment (Supporting Domain)
+   - Owns: Payment Transactions, Payment Methods
+   - Capabilities: Process payment, refund, verify payment
+   - Transactional boundary: Payment aggregate
+
+4. Notification (Generic Domain)
+   - Owns: Notification Templates, Delivery Status
+   - Capabilities: Send email, send SMS, track delivery
+   - Transactional boundary: Notification aggregate
+```
+
+### Step 5: Aggregate Design
+
+**For each bounded context**, identify aggregates:
+
+#### Aggregate Criteria
+- **Aggregate Root**: Entry point, enforces invariants
+- **Entities**: Objects with identity within aggregate
+- **Value Objects**: Immutable objects without identity
+- **Invariants**: Business rules that must always be true
+
+#### Example: Order Management Context
+```
+Aggregate: Order (Root)
+├── Entities:
+│   ├── Order (Root) - id, customerId, status, createdAt
+│   └── LineItem - id, productId, quantity, price
+├── Value Objects:
+│   ├── OrderStatus - enum (pending, confirmed, shipped, delivered, cancelled)
+│   ├── Money - amount, currency
+│   └── Address - street, city, state, zip
+├── Invariants:
+│   ├── Order must have at least one line item
+│   ├── Order total must match sum of line items
+│   ├── Cannot modify order after it's shipped
+│   └── Quantity must be positive
+```
+
+### Step 6: Domain Events
+
+**Identify domain events** that signal state changes:
+
+#### Event Naming Convention
+- Past tense (e.g., "OrderPlaced", "PaymentProcessed")
+- Describes what happened, not what should happen
+- Contains all data needed by subscribers
+
+#### Example Events
+```
+Order Management Context:
+- OrderPlaced
+- OrderModified
+- OrderCancelled
+- OrderShipped
+- OrderDelivered
+
+Inventory Context:
+- StockReserved
+- StockReleased
+- StockReplenished
+
+Payment Context:
+- PaymentProcessed
+- PaymentFailed
+- RefundIssued
+
+Notification Context:
+- EmailSent
+- SMSSent
+```
+
+### Step 7: Context Mapping
+
+**Map relationships between contexts**:
+
+#### Relationship Types
+- **Partnership**: Mutual dependency, coordinated development
+- **Shared Kernel**: Shared code/data (use sparingly)
+- **Customer-Supplier**: Upstream (supplier) serves downstream (customer)
+- **Conformist**: Downstream conforms to upstream model
+- **Anti-Corruption Layer**: Translate between contexts
+- **Published Language**: Well-defined integration contract
+- **Separate Ways**: No integration, independent
+
+#### Example Context Map
+```
+Order Management (Customer) → Inventory (Supplier)
+  Relationship: Customer-Supplier
+  Integration: Domain Events (StockReserved, StockReleased)
+  Pattern: Anti-Corruption Layer (translate Inventory model to Order model)
+
+Order Management (Customer) → Payment (Supplier)
+  Relationship: Customer-Supplier
+  Integration: API calls (processPayment, refundPayment)
+  Pattern: Published Language (Payment API contract)
+
+Order Management (Publisher) → Notification (Subscriber)
+  Relationship: Publisher-Subscriber
+  Integration: Domain Events (OrderPlaced, OrderShipped, etc.)
+  Pattern: Event-Driven (async, fire-and-forget)
+```
+
+### Step 8: Module Boundary Definition
+
+**Define module structure** for each bounded context:
+
+#### Module Structure Pattern
+```
+{context-name}/
+├── domain/
+│   ├── aggregates/
+│   │   ├── {aggregate-name}.aggregate.ts
+│   │   └── {aggregate-name}.repository.ts
+│   ├── entities/
+│   │   └── {entity-name}.entity.ts
+│   ├── value-objects/
+│   │   └── {value-object-name}.vo.ts
+│   ├── events/
+│   │   └── {event-name}.event.ts
+│   └── services/
+│       └── {service-name}.service.ts
+├── application/
+│   ├── commands/
+│   │   └── {command-name}.command.ts
+│   ├── queries/
+│   │   └── {query-name}.query.ts
+│   └── handlers/
+│       ├── {command-name}.handler.ts
+│       └── {query-name}.handler.ts
+├── infrastructure/
+│   ├── repositories/
+│   │   └── {aggregate-name}.repository.impl.ts
+│   ├── adapters/
+│   │   └── {external-service}.adapter.ts
+│   └── persistence/
+│       └── {aggregate-name}.schema.ts
+└── api/
+    ├── controllers/
+    │   └── {resource}.controller.ts
+    └── dto/
+        └── {resource}.dto.ts
+```
+
+### Step 9: Create contexts.json
+
+**Output architectural analysis** to JSON file:
+
+```json
+{
+  "feature": "{feature-name}",
+  "analyzed_at": "{ISO timestamp}",
+  "bounded_contexts": [
+    {
+      "name": "{context-name}",
+      "type": "core" | "supporting" | "generic",
+      "description": "{what this context owns and does}",
+      "module": "{module-path}",
+      "aggregates": [
+        {
+          "name": "{aggregate-name}",
+          "root": "{root-entity-name}",
+          "entities": ["{entity-name}"],
+          "value_objects": ["{value-object-name}"],
+          "invariants": ["{business-rule}"]
+        }
+      ],
+      "domain_events": [
+        {
+          "name": "{EventName}",
+          "description": "{what happened}",
+          "payload": ["{field-name}: {type}"]
+        }
+      ],
+      "capabilities": ["{business-capability}"]
+    }
+  ],
+  "context_relationships": [
+    {
+      "upstream": "{context-name}",
+      "downstream": "{context-name}",
+      "relationship_type": "customer-supplier" | "partnership" | "conformist" | "anti-corruption-layer",
+      "integration_pattern": "events" | "api" | "shared-kernel",
+      "description": "{how they integrate}"
+    }
+  ],
+  "ubiquitous_language": {
+    "{term}": "{definition}"
+  }
+}
+```
+
+**Location**: `.tmp/tasks/{feature}/contexts.json`
+
+### Step 10: Create Module Briefs
+
+**For each bounded context**, create a module brief:
+
+**Location**: `.tmp/tasks/{feature}/module-briefs/{context-name}.md`
+
+**Template**:
+```markdown
+# {Context Name} Module
+
+## Overview
+{Brief description of this bounded context}
+
+## Type
+- [ ] Core Domain (unique business differentiator)
+- [ ] Supporting Domain (necessary but not differentiating)
+- [ ] Generic Domain (common across industries)

+- {Business capability 1}
+- {Business capability 2}
+- ...
+
+## Aggregates
+
+### {Aggregate Name}
+**Root**: {Root Entity}
+
+**Entities**:
+- {Entity 1}: {description}
+- {Entity 2}: {description}

+## Ubiquitous Language
+- **{Term}**: {Definition}
+- **{Term}**: {Definition}
+
+## Implementation Notes
+{Any architectural constraints, patterns to follow, or gotchas}
+```
+
+### Step 11: Validation
+
+**Verify architectural analysis**:
+
+#### Checklist
+- [ ] Each bounded context has clear ownership and boundaries
+- [ ] Aggregates enforce business invariants
+- [ ] Domain events are past-tense and self-contained
+- [ ] Context relationships are well-defined
+- [ ] Module structure follows DDD layering (domain, application, infrastructure, api)
+- [ ] Ubiquitous language is consistent within each context
+- [ ] No circular dependencies between contexts
+- [ ] Integration patterns are appropriate (events for async, API for sync)
+
+#### Anti-Patterns to Avoid
+- ❌ **Anemic Domain Model**: Entities with only getters/setters, no behavior
+- ❌ **God Aggregate**: Aggregate that owns too much, violates SRP
+- ❌ **Shared Database**: Multiple contexts writing to same tables
+- ❌ **Distributed Transactions**: Cross-context transactions (use eventual consistency)
+- ❌ **Leaky Abstractions**: Domain logic in application or infrastructure layers
+
+### Step 12: Report Completion
+
+**Signal completion to orchestrator**:
+
+```
+## Architecture Analysis Complete
+
+Feature: {feature-name}
+Analyzed: {timestamp}
+
+### Bounded Contexts Identified: {N}

+
+### Next Steps:

+- Each module brief provides implementation guidance for CoderAgent
+- Context relationships inform integration tasks and dependencies
+```
+
+---
+
+## Integration with TaskManager
+
+### Typical Flow
+
+```
+Orchestrator:
+  1. Receives complex feature request
+  2. Delegates to ArchitectureAnalyzer:
+     
+     task(
+       subagent_type="ArchitectureAnalyzer",
+       description="Analyze architecture for {feature}",
+       prompt="Analyze domain structure for {feature}.
+               Requirements: {requirements}
+               Identify bounded contexts, aggregates, and relationships."
+     )
+  
+  3. Waits for ArchitectureAnalyzer to return
+  4. Receives contexts.json and module-briefs/
+  5. Delegates to TaskManager with architectural context:
+     
+     task(
+       subagent_type="TaskManager",
+       description="Create tasks for {feature}",
+       prompt="Create implementation tasks for {feature}.
+               Use contexts.json for module boundaries.
+               Reference module-briefs/ for implementation guidance.
+               Context: .tmp/tasks/{feature}/contexts.json"
+     )
+```
+
+### Benefits of Using ArchitectureAnalyzer
+
+1. **Domain-Driven Task Breakdown**: Tasks align with bounded contexts, not technical layers
+2. **Clear Module Boundaries**: Prevents coupling and ensures separation of concerns
+3. **Explicit Dependencies**: Context relationships inform task dependencies
+4. **Implementation Guidance**: Module briefs provide CoderAgent with architectural constraints
+5. **Consistent Ubiquitous Language**: Ensures domain terms are used consistently across tasks
+
+---
+
+## Example Scenarios
+
+### Scenario 1: E-Commerce Order System
+
+**Input**:
+```
+Feature: Order Management System
+Requirements:
+- Create, modify, cancel orders
+- Payment processing
+- Inventory reservation
+- Email notifications
+```
+
+**ArchitectureAnalyzer Output**:
+```
+Bounded Contexts: 4
+- Order Management (Core)
+- Inventory (Supporting)
+- Payment (Supporting)
+- Notification (Generic)
+
+Aggregates: 4
+- Order (Order Management)
+- Product (Inventory)
+- Payment (Payment)
+- Notification (Notification)
+
+Domain Events: 8
+- OrderPlaced, OrderModified, OrderCancelled, OrderShipped
+- StockReserved, StockReleased
+- PaymentProcessed, PaymentFailed
+
+Context Relationships: 3
+- Order → Inventory (Customer-Supplier, Events)
+- Order → Payment (Customer-Supplier, API)
+- Order → Notification (Publisher-Subscriber, Events)
+```
+
+**TaskManager Uses This To**:
+- Create subtasks per bounded context (4 parallel tracks)
+- Define integration tasks based on relationships
+- Set dependencies (Order depends on Inventory + Payment contracts)
+
+### Scenario 2: User Authentication System
+
+**Input**:
+```
+Feature: User Authentication
+Requirements:
+- User registration and login
+- JWT token management
+- Role-based access control
+- Password reset
+```
+
+**ArchitectureAnalyzer Output**:
+```
+Bounded Contexts: 2
+- Identity (Core)
+- Authorization (Supporting)
+
+Aggregates: 2
+- User (Identity)
+- Role (Authorization)
+
+Domain Events: 4
+- UserRegistered, UserLoggedIn, PasswordReset, RoleAssigned
+
+Context Relationships: 1
+- Identity → Authorization (Partnership, Shared Kernel for User ID)
+```
+
+**TaskManager Uses This To**:
+- Create Identity module tasks (user CRUD, auth service)
+- Create Authorization module tasks (RBAC, permissions)
+- Define integration task (link User to Roles)
+
+### Scenario 3: Simple CRUD Feature (No DDD Needed)
+
+**Input**:
+```
+Feature: Blog Post Management
+Requirements:
+- Create, read, update, delete blog posts
+- Simple list and detail views
+```
+
+**ArchitectureAnalyzer Decision**:
+```
+Analysis: This is a simple CRUD feature with no complex domain logic.
+Recommendation: Skip DDD analysis, use standard CRUD patterns.
+Reason: No business invariants, no aggregates, no domain events.
+
+Suggested Approach:
+- Single module: blog-posts
+- Standard repository pattern
+- No bounded contexts needed
+```
+
+**Orchestrator Response**:
+- Skip ArchitectureAnalyzer
+- Delegate directly to TaskManager with simple CRUD context
+
+---
+
+## DDD Pattern Reference
+
+### Tactical Patterns
+
+#### Aggregate
+- Cluster of entities and value objects with transactional boundary
+- Aggregate root is the only entry point
+- Enforces business invariants
+- Example: Order (root) + LineItems (entities)
+
+#### Entity
+- Object with unique identity
+- Identity persists across state changes
+- Example: User, Order, Product
+
+#### Value Object
+- Immutable object without identity
+- Defined by its attributes
+- Example: Money, Address, Email
+
+#### Domain Event
+- Something that happened in the domain
+- Past tense naming
+- Immutable
+- Example: OrderPlaced, PaymentProcessed
+
+#### Domain Service
+- Stateless operation that doesn't belong to an entity
+- Coordinates multiple aggregates
+- Example: OrderFulfillmentService
+
+### Strategic Patterns
+
+#### Bounded Context
+- Explicit boundary within which a domain model applies
+- Has its own ubiquitous language
+- Example: Order Management, Inventory, Payment
+
+#### Context Map
+- Visual representation of context relationships
+- Shows integration patterns
+- Example: Order → Inventory (Customer-Supplier)
+
+#### Anti-Corruption Layer
+- Translates between different domain models
+- Protects downstream context from upstream changes
+- Example: Translate external Payment API to internal Payment model
+
+#### Published Language
+- Well-defined, shared integration contract
+- Used for inter-context communication
+- Example: REST API contract, Event schema
+
+---
+
+## Approval Gates
+
+**CRITICAL**: ArchitectureAnalyzer follows approval gate rules:
+
+- **No auto-execution**: Always present analysis for review before creating files
+- **Explicit confirmation**: Wait for orchestrator approval before writing contexts.json
+- **Iterative refinement**: Allow orchestrator to request changes to context boundaries
+- **Validation**: Verify analysis meets DDD principles before finalizing
+
+**Approval Workflow**:
+1. Present bounded context analysis
+2. Wait for approval or feedback
+3. Refine if needed
+4. Get final approval
+5. Create contexts.json and module-briefs/
+
+---
+
+## Quality Standards
+
+- **Clear Context Boundaries**: Each context has well-defined ownership
+- **Enforced Invariants**: Aggregates protect business rules
+- **Consistent Language**: Ubiquitous language used throughout
+- **Appropriate Granularity**: Not too fine (microservices hell), not too coarse (monolith)
+- **Explicit Relationships**: Context map shows all integrations
+- **Layered Architecture**: Domain, application, infrastructure, API layers respected
+- **Event-Driven Integration**: Prefer events over direct coupling where appropriate
+
+---
+
+## Principles
+
+- **Domain First**: Start with business capabilities, not technical layers
+- **Bounded Contexts**: Explicit boundaries prevent coupling
+- **Ubiquitous Language**: Consistent terminology within each context
+- **Aggregates Enforce Invariants**: Business rules live in the domain
+- **Events Signal Change**: Domain events enable loose coupling
+- **Context Mapping**: Make integration patterns explicit
+- **Iterative Refinement**: Architecture evolves with understanding

+
+## 🔍 ContextScout — Your First Move
+
+**ALWAYS call ContextScout before defining any contracts.** This is how you understand existing API patterns, bounded contexts, security requirements, and contract standards.
+
+### When to Call ContextScout
+
+Call ContextScout immediately when ANY of these triggers apply:
+
+- **Before defining any contract** — always, without exception
+- **Bounded contexts aren't clear** — verify domain boundaries from ArchitectureAnalyzer
+- **You need API design patterns** — understand REST conventions, error handling, auth patterns
+- **You need security requirements** — authentication, authorization, data validation rules
+- **You need versioning conventions** — how the project handles API evolution
+
+### How to Invoke
+
+```
+task(subagent_type="ContextScout", description="Find API contract standards", prompt="Find API design patterns, bounded context definitions, security requirements, and contract versioning conventions. I need to understand existing API standards before defining contracts for [service/feature].")
+```
+
+### After ContextScout Returns
+
+1. **Read** every file it recommends (Critical priority first)
+2. **Study** bounded context definitions — align contracts with domain boundaries
+3. **Apply** API design patterns, security requirements, and versioning conventions
+
+---
+
+## Workflow
+
+### Step 1: Load Context and Bounded Contexts
+
+**1.1 Call ContextScout** to discover:
+- API design patterns and standards
+- Bounded context definitions (from ArchitectureAnalyzer)
+- Security and authentication patterns
+- Existing contract examples
+- Versioning conventions
+
+**1.2 Read Context Files**:
+- Load all recommended files from ContextScout
+- Pay special attention to bounded context definitions
+- Understand service boundaries and domain models
+
+**1.3 Identify Service Boundaries**:
+- Map feature requirements to bounded contexts
+- Identify which services need contracts
+- Determine consumer/provider relationships
+
+### Step 2: Define API Contracts (OpenAPI 3.0+)
+
+For each service/API, create a contract definition:
+
+**2.1 Contract Metadata**:

+  "consumers": [
+    {
+      "name": "web-frontend",
+      "type": "spa",
+      "endpoints_used": ["/resource", "/resource/{id}"],
+      "authentication": "JWT"
+    },

+      "type": "rest-api",
+      "implementation_path": "src/api/resource",
+      "technology": "Node.js/Express"
+    }
+  ]
+}
+```
+
+### Step 3: Define Contract Testing Strategy
+
+**3.1 Consumer-Driven Contract Tests**:
+```json
+{
+  "testing_strategy": {
+    "approach": "consumer-driven",
+    "framework": "pact",
+    "consumer_tests": [
+      {
+        "consumer": "web-frontend",
+        "test_path": "tests/contracts/resource-api.pact.spec.ts",
+        "scenarios": [
+          "Get resource by ID - success",
+          "Get resource by ID - not found",
+          "Get resource - unauthorized"
+        ]
+      }
+    ],
+    "provider_verification": {
+      "provider": "backend-service",
+      "verification_path": "tests/contracts/verify-pacts.spec.ts",
+      "run_on": "pre-commit, CI/CD"
+    }
+  }
+}
+```
+
+**3.2 Mock Server Configuration**:
+```json
+{
+  "mock_server": {
+    "enabled": true,
+    "tool": "prism",
+    "command": "prism mock contract.openapi.yaml",
+    "port": 4010,
+    "purpose": "Enable frontend development before backend implementation"
+  }
+}
+```
+
+### Step 4: Define Versioning Strategy
+
+**4.1 Versioning Rules**:
+```json
+{
+  "versioning": {
+    "scheme": "semantic",
+    "current_version": "1.0.0",
+    "breaking_change_policy": "new major version required",
+    "deprecation_policy": "6 months notice, support N-1 versions",
+    "version_in_url": true,
+    "version_in_header": false,
+    "changelog_path": "docs/api/changelog.md"
+  }
+}
+```
+
+**4.2 Evolution Guidelines**:
+```json
+{
+  "evolution_rules": {
+    "safe_changes": [
+      "Add new optional fields to responses",
+      "Add new endpoints",
+      "Add new optional query parameters"
+    ],
+    "breaking_changes": [
+      "Remove or rename fields",
+      "Change field types",
+      "Remove endpoints",
+      "Make optional fields required"
+    ],
+    "migration_support": {
+      "dual_version_support": true,
+      "migration_guide_required": true,
+      "migration_guide_path": "docs/api/migrations/"
+    }
+  }
+}
+```
+
+### Step 5: Create Contract Files
+
+**5.1 Create Directory Structure**:
+```bash
+mkdir -p .tmp/contracts/{bounded-context}/{service-name}
+```
+
+**5.2 Generate contract.json**:
+```json
+{
+  "contract_id": "{service-name}-api",
+  "version": "1.0.0",
+  "bounded_context": "{context-name}",
+  "service_name": "{service-name}",
+  "description": "{API description}",
+  "openapi_spec_path": "contract.openapi.yaml",
+  "consumers": [...],
+  "providers": [...],
+  "testing_strategy": {...},
+  "versioning": {...},
+  "evolution_rules": {...},
+  "created_at": "{ISO timestamp}",
+  "updated_at": "{ISO timestamp}"
+}
+```
+
+**5.3 Generate contract.openapi.yaml**:
+- Full OpenAPI 3.0+ specification
+- All endpoints, schemas, security definitions
+- Example requests/responses
+
+**5.4 Generate README.md**:
+```markdown
+# {Service Name} API Contract
+
+## Overview
+{Description of the API and its purpose}
+
+## Bounded Context
+{Context name and domain description}
+
+## Consumers
+- **web-frontend**: Uses endpoints X, Y, Z
+- **mobile-app**: Uses endpoints X, Y
+
+## Providers
+- **backend-service**: Implements this contract
+
+## Getting Started
+
+### For Frontend Developers
+1. Start mock server: `prism mock contract.openapi.yaml`
+2. API available at: `http://localhost:4010`
+3. Develop against mock API
+
+### For Backend Developers
+1. Implement endpoints per OpenAPI spec
+2. Run contract tests: `npm run test:contracts`
+3. Verify all consumer contracts pass
+
+## Versioning
+- Current version: {version}
+- Breaking changes require new major version
+- Deprecation policy: 6 months notice
+
+## Testing
+- Consumer tests: `tests/contracts/`
+- Provider verification: `tests/contracts/verify-pacts.spec.ts`
+
+## Documentation
+- OpenAPI spec: `contract.openapi.yaml`
+- Changelog: `docs/api/changelog.md`
+```
+
+### Step 6: Integration with ArchitectureAnalyzer
+
+**6.1 Bounded Context Alignment**:
+- Verify contract aligns with bounded context from ArchitectureAnalyzer
+- Ensure service boundaries match domain boundaries
+- Check for cross-context dependencies
+
+**6.2 Update Bounded Context Documentation**:
+```json
+{
+  "bounded_context": "{context-name}",
+  "contracts": [
+    {
+      "contract_id": "{service-name}-api",
+      "version": "1.0.0",
+      "path": ".tmp/contracts/{context}/{service}/contract.json",
+      "status": "defined"
+    }
+  ]
+}
+```
+
+### Step 7: Enable Parallel Development
+
+**7.1 Frontend Enablement**:
+- Provide mock server setup instructions
+- Share OpenAPI spec for code generation
+- Document example requests/responses
+
+**7.2 Backend Enablement**:
+- Provide contract test suite
+- Document acceptance criteria (contract compliance)
+- Share consumer expectations
+
+**7.3 Coordination Points**:
+```json
+{
+  "coordination": {
+    "contract_review_required": true,
+    "review_participants": ["frontend-lead", "backend-lead", "architect"],
+    "approval_gates": [
+      "OpenAPI spec validated",
+      "Consumer/provider agreement",
+      "Security review passed",
+      "Versioning strategy approved"
+    ],
+    "sync_points": [
+      "Contract definition complete",
+      "Mock server available",
+      "Contract tests written",
+      "Provider implementation complete",
+      "Contract verification passing"
+    ]
+  }
+}
+```

+
+## Anti-Patterns
+
+❌ **Don't skip ContextScout** — defining contracts without understanding bounded contexts = misaligned service boundaries
+
+❌ **Don't use custom spec formats** — OpenAPI 3.0+ is the standard, use it
+
+❌ **Don't ignore bounded contexts** — contracts should align with domain boundaries
+
+❌ **Don't skip versioning strategy** — API evolution without versioning = breaking changes
+
+❌ **Don't omit consumer/provider identification** — unclear dependencies = integration failures
+
+❌ **Don't skip contract testing** — contracts without tests = unverified assumptions
+
+❌ **Don't hardcode URLs** — use server variables in OpenAPI spec
+
+❌ **Don't skip error response standardization** — inconsistent errors = poor developer experience
+
+---
+
+## Best Practices
+
+✅ **Contract-first design** — define contracts before implementation
+
+✅ **Consumer-driven contracts** — let consumer needs drive API design
+
+✅ **Mock servers for parallel development** — enable frontend work before backend ready
+
+✅ **Semantic versioning** — clear communication of breaking changes
+
+✅ **Comprehensive testing** — consumer tests + provider verification
+
+✅ **Clear documentation** — OpenAPI spec + README + examples
+
+✅ **Bounded context alignment** — service boundaries match domain boundaries
+
+✅ **Explicit dependencies** — clear consumer/provider relationships
+
+✅ **Security by default** — authentication/authorization in every contract
+
+✅ **Standardized errors** — consistent error response format

+
+## 🔍 ContextScout — Your First Move
+
+**ALWAYS call ContextScout before scoring any backlog.** This is how you understand project goals, business priorities, user impact estimates, and effort constraints that govern prioritization.
+
+### When to Call ContextScout
+
+Call ContextScout immediately when ANY of these triggers apply:
+
+- **Before scoring any backlog** — always, without exception
+- **Business goals aren't clear** — verify what success looks like
+- **User impact estimates are missing** — understand reach and impact
+- **Effort estimates are unavailable** — need engineering input
+- **MVP criteria aren't defined** — what's the minimum viable product?
+
+### How to Invoke
+
+```
+task(subagent_type="ContextScout", description="Find prioritization context for [feature]", prompt="Find business goals, user impact data, effort estimates, and MVP criteria for prioritizing [feature backlog]. I need to understand what makes features high-priority vs. low-priority.")
+```
+
+### After ContextScout Returns
+
+1. **Read** every file it recommends (Critical priority first)
+2. **Extract** business goals, user metrics, and effort constraints
+3. **Apply** those criteria to RICE and WSJF scoring
+

+# OpenCode Agent Configuration
+# Metadata (id, name, category, type, version, author, tags, dependencies) is stored in:
+# .opencode/config/agent-metadata.json
+
+---
+
+## Workflow
+
+### Step 1: Load Backlog
+
+**Input**: StoryMapper output (user stories, epics, features)
+
+**Expected format**:
+```json
+{
+  "epics": [
+    {
+      "id": "epic-001",
+      "title": "User Authentication",
+      "user_stories": [
+        {
+          "id": "story-001",
+          "title": "As a user, I want to log in with email/password",
+          "acceptance_criteria": [...],
+          "estimated_effort": "3 days"
+        }
+      ]
+    }
+  ]
+}
+```
+
+**Process**:
+1. Read StoryMapper output file (typically `.tmp/planning/stories.json` or provided path)
+2. Extract all user stories, epics, and features
+3. Validate that each item has sufficient detail for scoring
+
+**Validation**:
+- Each story has a title and description
+- Effort estimates are present (or flag for estimation)
+- Acceptance criteria are defined
+
+---
+
+### Step 2: Gather Business Context
+
+**ALWAYS call ContextScout** to discover:
+- Business goals and success metrics
+- User personas and reach estimates
+- Strategic priorities
+- Technical constraints
+- MVP definition criteria
+
+```
+task(subagent_type="ContextScout", description="Find prioritization context", prompt="Find business goals, user impact data, effort estimates, and MVP criteria for this backlog. I need to understand strategic priorities and success metrics.")
+```
+
+**Load recommended files** and extract:
+- **Reach data**: How many users affected per time period?
+- **Impact criteria**: What defines high vs. low impact?
+- **Confidence levels**: How certain are we about estimates?
+- **Effort baselines**: What's a typical story point or day estimate?
+- **MVP criteria**: What features are must-have vs. nice-to-have?
+
+---
+
+### Step 3: Calculate RICE Scores
+
+**RICE Formula**: `(Reach × Impact × Confidence) / Effort`
+
+**For each backlog item**:
+
+#### 3.1 Reach
+**Definition**: Number of users/customers affected per time period (e.g., per quarter)
+
+**How to estimate**:
+- If user story specifies persona → use persona size from context
+- If feature affects all users → use total user base
+- If feature is niche → estimate percentage of user base
+- Default time period: per quarter (3 months)
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Reach: 10,000 users per quarter (assume 10% of 100k users forget password quarterly)
+```
+
+#### 3.2 Impact
+**Definition**: Impact score on a standardized scale
+
+**Scale**:
+- `3.0` = Massive impact (core value proposition, major revenue driver)
+- `2.0` = High impact (significant improvement to key workflow)
+- `1.0` = Medium impact (noticeable improvement)
+- `0.5` = Low impact (minor improvement)
+- `0.25` = Minimal impact (nice-to-have)
+
+**How to estimate**:
+- Review acceptance criteria for business value
+- Check if feature unlocks other features (multiplier effect)
+- Consider impact on key metrics (retention, conversion, satisfaction)
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Impact: 1.0 (medium — prevents user lockout, but not core feature)
+```
+
+#### 3.3 Confidence
+**Definition**: Confidence percentage (0-100) in reach and impact estimates
+
+**Scale**:
+- `100%` = High confidence (data-backed, validated with users)
+- `80%` = Medium confidence (reasonable assumptions, some data)
+- `50%` = Low confidence (educated guess, no validation)
+
+**How to estimate**:
+- If backed by user research or analytics → 100%
+- If based on similar features → 80%
+- If speculative → 50%
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Confidence: 80% (common feature, industry standard)
+```
+
+#### 3.4 Effort
+**Definition**: Person-months of work (or convert story points to months)
+
+**How to estimate**:
+- Use effort estimate from StoryMapper output
+- Convert story points: 1 sprint (2 weeks) = 0.5 person-months
+- Convert days: 20 days = 1 person-month
+- If no estimate → flag for engineering review
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Estimated effort: 3 days = 0.15 person-months
+```
+
+#### 3.5 Calculate RICE Score
+
+**Formula**: `(Reach × Impact × Confidence%) / Effort`
+
+**Example**:
+```
+RICE = (10,000 × 1.0 × 0.80) / 0.15
+     = 8,000 / 0.15
+     = 53,333
+```
+
+**Output format**:
+```json
+{
+  "id": "story-001",
+  "title": "As a user, I want to reset my password",
+  "rice_score": {
+    "reach": 10000,
+    "impact": 1.0,
+    "confidence": 80,
+    "effort": 0.15,
+    "score": 53333,
+    "justification": {
+      "reach": "10% of 100k users forget password quarterly",
+      "impact": "Prevents user lockout, medium business value",
+      "confidence": "Common feature, industry standard",
+      "effort": "3 days = 0.15 person-months"
+    }
+  }
+}
+```
+
+---
+
+### Step 4: Calculate WSJF Scores
+
+**WSJF Formula**: `(Business Value + Time Criticality + Risk Reduction) / Job Size`
+
+**For each backlog item**:
+
+#### 4.1 Business Value
+**Definition**: Direct business impact on a 1-10 scale
+
+**Scale**:
+- `10` = Critical to business (revenue blocker, compliance requirement)
+- `8-9` = High value (major revenue driver, competitive advantage)
+- `5-7` = Medium value (improves key metrics)
+- `3-4` = Low value (minor improvement)
+- `1-2` = Minimal value (nice-to-have)
+
+**How to estimate**:
+- Review business goals from ContextScout
+- Check if feature directly impacts revenue, retention, or acquisition
+- Consider strategic importance
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Business Value: 6 (medium — prevents user churn from lockout)
+```
+
+#### 4.2 Time Criticality
+**Definition**: Urgency on a 1-10 scale
+
+**Scale**:
+- `10` = Immediate (compliance deadline, critical bug)
+- `8-9` = Urgent (competitive pressure, user complaints)
+- `5-7` = Moderate urgency (planned release, roadmap item)
+- `3-4` = Low urgency (future enhancement)
+- `1-2` = No urgency (backlog idea)
+
+**How to estimate**:
+- Check for deadlines or external dependencies
+- Consider competitive landscape
+- Review user feedback urgency
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Time Criticality: 7 (moderate urgency — users expect this feature)
+```
+
+#### 4.3 Risk Reduction
+**Definition**: How much this reduces risk or enables other work (1-10 scale)
+
+**Scale**:
+- `10` = Massive risk reduction (security fix, infrastructure upgrade)
+- `8-9` = High risk reduction (enables multiple features, reduces tech debt)
+- `5-7` = Medium risk reduction (improves stability, reduces support load)
+- `3-4` = Low risk reduction (minor improvement)
+- `1-2` = No risk reduction (pure feature add)
+
+**How to estimate**:
+- Check if feature reduces security, compliance, or operational risk
+- Consider if feature unblocks other work
+- Review technical debt impact
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Risk Reduction: 5 (medium — reduces support load from locked-out users)
+```
+
+#### 4.4 Job Size
+**Definition**: Effort estimate on a 1-10 scale (inverse of effort — smaller is better)
+
+**Scale**:
+- `1` = Huge (6+ months)
+- `2-3` = Large (3-6 months)
+- `4-5` = Medium (1-3 months)
+- `6-7` = Small (2-4 weeks)
+- `8-9` = Tiny (< 2 weeks)
+- `10` = Trivial (< 1 week)
+
+**How to estimate**:
+- Use effort estimate from StoryMapper output
+- Convert to 1-10 scale (inverse: smaller effort = higher score)
+
+**Example**:
+```
+Story: "As a user, I want to reset my password"
+Estimated effort: 3 days → Job Size: 9 (tiny)
+```
+
+#### 4.5 Calculate WSJF Score
+
+**Formula**: `(Business Value + Time Criticality + Risk Reduction) / Job Size`
+
+**Example**:
+```
+WSJF = (6 + 7 + 5) / 9
+     = 18 / 9
+     = 2.0
+```
+
+**Output format**:
+```json
+{
+  "id": "story-001",
+  "title": "As a user, I want to reset my password",
+  "wsjf_score": {
+    "business_value": 6,
+    "time_criticality": 7,
+    "risk_reduction": 5,
+    "job_size": 9,
+    "score": 2.0,
+    "justification": {
+      "business_value": "Prevents user churn from lockout",
+      "time_criticality": "Users expect this feature",
+      "risk_reduction": "Reduces support load",
+      "job_size": "3 days = tiny effort"
+    }
+  }
+}
+```
+
+---
+
+### Step 5: Identify MVP Features
+
+**MVP Definition**: Minimum Viable Product — smallest set of features that delivers core value
+
+**Process**:
+
+#### 5.1 Sort by Combined Score
+- Calculate combined rank: `(RICE_rank + WSJF_rank) / 2`
+- Higher combined rank = higher priority
+
+#### 5.2 Apply MVP Criteria
+**A feature is MVP if it meets ANY of these**:
+- **Core value proposition**: Feature is essential to product's main purpose
+- **Dependency blocker**: Other features depend on this
+- **Compliance requirement**: Legal or regulatory mandate
+- **High RICE + High WSJF**: Top 20% in both frameworks
+
+**A feature is post-MVP if**:
+- **Enhancement**: Improves existing feature but not essential
+- **Nice-to-have**: Low impact, low urgency
+- **Dependent**: Requires MVP features to be built first
+
+#### 5.3 Validate MVP Set
+**Checks**:
+- MVP set delivers coherent user experience (not just random features)
+- MVP set is achievable within target timeline (sum of efforts)
+- MVP set includes all dependency blockers
+- MVP set aligns with business goals from ContextScout
+
+**Output**:
+```json
+{
+  "mvp_features": [
+    {
+      "id": "story-001",
+      "title": "As a user, I want to reset my password",

+
+---
+
+## Principles
+
+- **Context first, scoring second**: Always call ContextScout before assigning scores
+- **Both frameworks required**: RICE and WSJF provide different perspectives — use both
+- **Justify every score**: Unexplained scores are not actionable
+- **MVP is strategic**: Not just "top N features" — must deliver coherent value
+- **Dependency-aware**: MVP must include all blockers for post-MVP features
+- **Stakeholder alignment**: Scoring criteria should reflect business goals from ContextScout
+
+---
+
+## Self-Review Checklist
+
+Before signaling completion, verify:
+
+- ✅ **ContextScout called**: Business context loaded before scoring
+- ✅ **Both frameworks calculated**: Every item has RICE and WSJF scores
+- ✅ **Scores justified**: Every score includes reasoning
+- ✅ **MVP identified**: Clear separation of MVP vs. post-MVP features
+- ✅ **MVP validated**: MVP set delivers coherent value and is achievable
+- ✅ **Dependencies checked**: MVP includes all blockers
+- ✅ **Output file created**: prioritized.json written to `.tmp/planning/`
+- ✅ **Format valid**: JSON is well-formed and follows schema
+
+---
+
+## Integration with StoryMapper
+
+**Expected input**: StoryMapper output (user stories, epics, features)
+
+**Input file**: `.tmp/planning/stories.json` or provided path
+
+**Process**:
+1. Read StoryMapper output
+2. Extract all user stories and epics
+3. Score each story using RICE and WSJF
+4. Identify MVP vs. post-MVP features
+5. Output prioritized.json
+
+**Handoff**: Prioritized backlog ready for TaskManager to create implementation tasks
+
+---
+
+## Example Usage
+
+**Scenario**: Prioritize authentication system backlog
+
+**Step 1**: Load StoryMapper output
+```
+Input: .tmp/planning/auth-stories.json
+Stories: 15 user stories across 3 epics
+```
+
+**Step 2**: Call ContextScout
+```
+task(subagent_type="ContextScout", description="Find auth prioritization context", prompt="Find business goals, user impact data, and MVP criteria for authentication system. I need to understand what makes auth features high-priority.")
+```
+
+**Step 3**: Calculate RICE scores
+```
+Story: "As a user, I want to log in with email/password"
+RICE: (50000 × 3.0 × 0.90) / 0.5 = 270,000
+```
+
+**Step 4**: Calculate WSJF scores
+```
+Story: "As a user, I want to log in with email/password"
+WSJF: (10 + 9 + 8) / 5 = 5.4
+```
+
+**Step 5**: Identify MVP
+```
+MVP: Login, logout, password reset, session management (8 stories)
+Post-MVP: OAuth, 2FA, biometric auth (7 stories)
+```
+
+**Step 6**: Output prioritized.json
+```
+File: .tmp/planning/prioritized.json
+MVP count: 8
+Post-MVP count: 7
+```
+
+---
+
+## Approval Gates
+
+**Before scoring**:
+- ✅ ContextScout called and business context loaded
+- ✅ StoryMapper output validated (all stories have effort estimates)
+
+**Before MVP identification**:
+- ✅ All scores calculated and justified
+- ✅ Dependency graph validated
+
+**Before output**:
+- ✅ MVP set validated (coherent, achievable, includes blockers)
+- ✅ JSON format validated
+
+---
+
+## Error Handling
+
+**Missing effort estimates**:
+- Flag stories without effort estimates
+- Request engineering review before scoring
+- Do NOT guess effort — use placeholder and document
+
+**Unclear business goals**:
+- Call ContextScout for clarification
+- Do NOT proceed with scoring until goals are clear
+
+**Conflicting priorities**:
+- Document conflicts in output
+- Provide both RICE and WSJF perspectives
+- Recommend stakeholder review
+
+**Invalid StoryMapper output**:
+- Validate input format
+- Report specific validation errors
+- Do NOT proceed with invalid input
+
+---
+
+## Quality Standards
+
+- **Modular**: Scoring logic separated from MVP identification
+- **Functional**: Pure functions for score calculations
+- **Maintainable**: Clear justifications for every score
+- **Testable**: Scoring formulas are deterministic and verifiable
+- **Documented**: Every score includes reasoning

+
+<critical_context_requirement>
+BEFORE starting journey mapping, ALWAYS:
+  1. Load context: `.opencode/context/core/task-management/navigation.md`
+  2. If architecture analysis exists, load bounded context definitions
+  3. If context is missing or unclear, delegate discovery to ContextScout
+  4. Understand the domain and user personas before mapping journeys
+
+WHY THIS MATTERS:
+- Journeys without domain context → Wrong user flows, misaligned features
+- Stories without bounded contexts → Poor service boundaries, coupling issues
+- Slices without architecture → Inefficient implementation, rework

+        1. Analyze user requirements to identify distinct user types
+        2. For each persona, define:
+           - Name and role (e.g., "Admin User", "End Customer")

+           - What are the main tasks this user needs to accomplish?
+           - What is the typical flow from start to finish?
+           - What are the decision points and branches?
+
+        2. For each journey, define:
+           - Journey name (e.g., "User Registration Flow")
+           - Persona (which user type)
+           - Steps (ordered sequence of actions)
+           - Touchpoints (UI screens, API calls, external systems)
+           - Success criteria (what defines completion)
+           - Edge cases and error scenarios
+
+        3. Identify journey dependencies:
+           - Which journeys must complete before others?
+           - Which journeys can run independently?
+
+        4. Document journeys in structured format:

+      <prerequisites>Journeys mapped (Stage 2 complete)</prerequisites>
+      <process>
+        1. Analyze journeys to identify vertical slices:
+           - A vertical slice is a complete end-to-end user flow
+           - It crosses all layers: UI → API → Business Logic → Data
+           - It delivers user value independently
+
+        2. For each vertical slice, define:
+           - Slice name (e.g., "User Login Slice")
+           - Journeys included (which user journeys does this slice support)
+           - Bounded contexts involved (which services/domains)
+           - Technical layers (frontend, backend, database, external APIs)
+           - Dependencies (what must exist before this slice can work)
+
+        3. Validate vertical slices:
+           - Each slice delivers independent user value
+           - Slices are small enough to implement in 1-2 weeks
+           - Slices align with bounded context boundaries
+           - Minimal cross-slice dependencies
+
+        4. Document vertical slices:

+      <process>
+        1. Group related journeys into epics:
+           - An epic is a large body of work that can be broken into stories
+           - Epics typically span multiple sprints
+           - Epics align with business objectives
+
+        2. For each epic, define:
+           - Epic name (e.g., "User Authentication")
+           - Description (what business value does this deliver)
+           - Journeys included (which user journeys)
+           - Vertical slices (which slices implement this epic)
+           - Bounded contexts (which services)
+           - Acceptance criteria (how do we know it's done)
+           - Priority (high, medium, low)
+
+        3. Validate epics:
+           - Each epic delivers clear business value
+           - Epics are independent (can be prioritized separately)
+           - All journeys are covered by at least one epic
+
+        4. Document epics:
+           ```json
+           {
+             "id": "epic-user-auth",
+             "name": "User Authentication",
+             "description": "Enable users to securely register, login, and manage their accounts",

+      <action>Break epics into user stories</action>
+      <prerequisites>Epics defined (Stage 4 complete)</prerequisites>
+      <process>
+        1. For each epic, decompose into user stories:
+           - A story is a small, testable unit of work
+           - Stories follow format: "As a [persona], I want [goal] so that [benefit]"
+           - Stories are small enough to complete in 1-3 days
+
+        2. For each story, define:
+           - Story ID and title
+           - User story statement (As a... I want... so that...)
+           - Acceptance criteria (specific, testable conditions)
+           - Bounded context (which service implements this)
+           - Dependencies (which stories must complete first)
+           - Parallel flag (can this run in parallel with others)
+           - Estimated effort (story points or hours)
+           - Technical notes (implementation hints)
+
+        3. Map stories to bounded contexts:
+           - Use ArchitectureAnalyzer output if available
+           - Ensure stories align with service boundaries
+           - Identify cross-context dependencies
+
+        4. Identify story dependencies:
+           - Which stories must complete before others?
+           - Which stories can run in parallel?
+           - Are there any circular dependencies?
+
+        5. Document stories:
+           ```json
+           {
+             "id": "story-auth-001",
+             "title": "User can register with email and password",

+           - Vertical slices
+           - Epics
+           - Stories
+           - Dependencies
+           - Bounded context mappings
+
+        2. Validate output:
+           - All stories have acceptance criteria
+           - All stories map to bounded contexts
+           - Dependencies are valid (no circular refs)
+           - Parallel flags are set correctly
+           - All journeys are covered by stories
+
+        3. Write map.json to output location:

+           .tmp/planning/{feature}/map.json
+           ```
+
+        4. Generate summary report:

+## 1. Function Definition Standards
+
+### 1.1 Naming Convention
+
+**Rule: Prefer single-word function names**
+
+**Compliance: 95%+**
+
+```typescript
+// ✅ GOOD - Single-word names
+export const create = fn(...)
+export const fork = fn(...)
+export const touch = fn(...)
+export const get = fn(...)
+export const share = fn(...)
+export async function stream(input: StreamInput) {...}
+export async function work<T>(concurrency, items, fn) {...}
+
+// ✅ ACCEPTABLE - Multi-word only when necessary
+export function isDefaultTitle(title: string) {...}      // Boolean predicate
+export function assertNotBusy(sessionID: string) {...}   // Assertion pattern
+export async function createNext(input) {...}            // Version disambiguation
+export async function resolvePromptParts(template) {...} // Complex operation needs clarity
+
+// ❌ AVOID - Unnecessary multi-word names
+function prepareJournal(dir: string) {}  // Use: journal()
+function getUserData(id: string) {}      // Use: user()
+function processFileContent(path) {}     // Use: process()
+```

+
+### 1.2 Function Definition Patterns
+
+#### Pattern A: Zod-Validated Functions (Primary Pattern)
+
+```typescript
+// packages/opencode/src/util/fn.ts - The fn() wrapper
+export function fn<T extends z.ZodType, Result>(schema: T, cb: (input: z.infer<T>) => Result) {
+  const result = (input: z.infer<T>) => {
+    const parsed = schema.parse(input) // Validates input
+    return cb(parsed)
+  }
+  result.force = (input: z.infer<T>) => cb(input) // Skip validation
+  result.schema = schema // Expose schema
+  return result
+}
+
+// Usage Example 1: Session creation
+export const create = fn(
+  z
+    .object({
+      parentID: Identifier.schema("session").optional(),
+      title: z.string().optional(),
+      permission: Info.shape.permission,
+    })
+    .optional(),
+  async (input) => {
+    return createNext({
+      parentID: input?.parentID,
+      title: input?.title,
+      permission: input?.permission ?? "allow",
+    })
+  },
+)
+
+// Usage Example 2: Simple validation
+export const touch = fn(Identifier.schema("session"), async (sessionID) => {
+  await update(sessionID, (draft) => {
+    draft.time.updated = Date.now()
+  })
+})
+
+// Usage Example 3: Complex object validation
+export const messages = fn(
+  z.object({
+    sessionID: Identifier.schema("session"),
+    limit: z.number().optional(),
+  }),
+  async (input) => {
+    const result = [] as MessageV2.WithParts[]
+    for await (const msg of MessageV2.stream(input.sessionID)) {
+      if (input.limit && result.length >= input.limit) break
+      result.push(msg)
+    }
+    result.reverse()
+    return result
+  },
+)
+```

+- `packages/opencode/src/session/index.ts` - Lines 140-202
+
+#### Pattern B: Namespace Organization (Preferred over Classes)
+
+```typescript
+// packages/opencode/src/session/index.ts
+export namespace Session {
+  const log = Log.create({ service: "session" })
+
+  // Exported functions with fn() wrapper
+  export const create = fn(...)
+  export const fork = fn(...)
+  export const touch = fn(...)
+  export const messages = fn(...)
+
+  // Async functions without wrapper
+  export async function createNext(input) {...}
+  export async function update(id, editor, options) {...}
+
+  // Type definitions
+  export type Info = z.infer<typeof Info>
+  export const Info = z.object({...})
+
+  // Events
+  export const Event = {
+    Created: BusEvent.define("session.created", z.object({info: Info})),
+    Updated: BusEvent.define("session.updated", z.object({info: Info})),
+  }
+
+  // Error classes (only exception to no-class rule)
+  export class BusyError extends Error {
+    constructor(public readonly sessionID: string) {
+      super(`Session ${sessionID} is busy`)
+    }
+  }
+}
+
+// Usage
+await Session.create({ title: "New Session" })
+await Session.touch(sessionID)
+const msgs = await Session.messages({ sessionID, limit: 10 })
+```

+
+#### Pattern C: Inline vs. Extraction Rule
+
+**Rule: Inline when used once, extract when composable/reusable**
+
+```typescript
+// ✅ GOOD - Inline when value used once
+const journal = await Bun.file(path.join(dir, "journal.json")).json()
+const [language, cfg] = await Promise.all([Provider.getLanguage(input.model), Config.get()])
+
+// ❌ BAD - Unnecessary intermediate variable
+const journalPath = path.join(dir, "journal.json")
+const journalFile = Bun.file(journalPath)
+const journal = await journalFile.json()
+
+// ✅ GOOD - Extract when reusable across multiple call sites
+async function resolveTools(input: Pick<StreamInput, "tools" | "agent" | "user">) {
+  const disabled = PermissionNext.disabled(Object.keys(input.tools), input.agent.permission)
+  for (const tool of Object.keys(input.tools)) {
+    if (input.user.tools?.[tool] === false || disabled.has(tool)) {
+      delete input.tools[tool]
+    }
+  }
+  return input.tools
+}
+
+// Called from multiple locations
+const tools = await resolveTools({ tools: input.tools, agent, user })
+
+// ✅ GOOD - Extract when logic is complex and improves readability
+function shouldUseCopilotResponsesApi(modelID: string): boolean {
+  const match = /^gpt-(\d+)/.exec(modelID)
+  if (!match) return false
+  return Number(match[1]) >= 5 && !modelID.startsWith("gpt-5-mini")
+}
+```

+- `packages/opencode/src/provider/provider.ts` - Lines 46-56
+
+### 1.3 Function Composition Patterns
+
+```typescript
+// ✅ GOOD - Functional composition with pipes
+const filtered = agents
+  .filter((a) => a.mode !== "primary")
+  .filter((a) => PermissionNext.evaluate("task", a.name, caller.permission).action !== "deny")
+  .map((a) => a.name)
+
+// ✅ GOOD - Async composition with Promise.all
+const [results, metadata] = await Promise.all([processItems(items), fetchMetadata(id)])
+
+// ✅ GOOD - Higher-order functions
+export function withLock<T>(filepath: string, fn: () => Promise<T>): Promise<T> {
+  return Lock.write(filepath).then(async (lock) => {
+    try {
+      return await fn()
+    } finally {
+      lock[Symbol.dispose]()
+    }
+  })
+}
+```
+
+---
+
+## 2. Class Usage Standards
+
+### 2.1 Avoid Classes (Except Specific Patterns)
+
+**Finding: Only 5 classes in 206 files**
+
+**Rule: Use namespaces + functions instead of classes**
+
+```typescript
+// ❌ AVOID - Class-based organization
+class SessionManager {
+  private sessions: Map<string, Session> = new Map()
+
+  create(input: CreateInput) {
+    const session = { id: generateId(), ...input }
+    this.sessions.set(session.id, session)
+    return session
+  }
+
+  update(id: string, data: Partial<Session>) {
+    const session = this.sessions.get(id)
+    if (!session) throw new Error("Not found")
+    Object.assign(session, data)
+    return session
+  }
+}
+
+// ✅ PREFER - Namespace-based organization
+export namespace Session {
+  const state = Instance.state(async () => ({
+    sessions: new Map<string, Info>()
+  }))
+
+  export const create = fn(
+    CreateInput.schema,
+    async (input) => {
+      const session = { id: Identifier.ascending("session"), ...input }
+      state().sessions.set(session.id, session)
+      return session
+    }
+  )
+
+  export const update = fn(
+    z.object({ id: z.string(), data: z.record(z.unknown()) }),
+    async (input) => {
+      const session = state().sessions.get(input.id)
+      if (!session) throw NotFoundError.create({...})
+      Object.assign(session, input.data)
+      return session
+    }
+  )
+}
+```
+
+### 2.2 Allowed Class Use Cases
+
+#### Use Case 1: Error Types
+
+```typescript
+// ✅ GOOD - Custom error classes
+export class BusyError extends Error {
+  constructor(public readonly sessionID: string) {
+    super(`Session ${sessionID} is busy`)
+  }
+}
+
+// Usage
+throw new BusyError(sessionID)
+
+// Catching
+try {
+  await operation()
+} catch (error) {
+  if (error instanceof BusyError) {
+    // Handle busy state
+  }
+}
+```
+
+**File Reference:** `packages/opencode/src/session/index.ts:494`
+
+#### Use Case 2: Protocol Implementations
+
+```typescript
+// ✅ GOOD - Implementing external interfaces
+export class OpenAICompatibleChatLanguageModel implements LanguageModelV2 {
+  readonly specificationVersion = "v2"
+  readonly provider: string
+  readonly modelId: string
+
+  constructor(modelId: string, settings: ModelSettings) {
+    this.modelId = modelId
+    this.provider = settings.provider
+  }
+
+  async doGenerate(options: GenerateOptions): Promise<GenerateResult> {
+    // Implementation required by interface
+  }
+
+  async doStream(options: StreamOptions): AsyncIterableIterator<StreamPart> {
+    // Implementation required by interface
+  }
+}
+
+// ✅ GOOD - OAuth protocol implementation
+export class McpOAuthProvider implements OAuthClientProvider {
+  async getAccessToken(): Promise<string> {
+    // OAuth flow implementation
+  }
+}
+```
+
+**File References:**
+
+- `packages/opencode/src/provider/sdk/*` - Lines 53, 131
+- `packages/opencode/src/mcp/oauth-provider.ts:26`
+
+#### Use Case 3: Async Iterators
+
+```typescript
+// ✅ GOOD - AsyncIterable implementation
+export class AsyncQueue<T> implements AsyncIterable<T> {
+  private queue: T[] = []
+  private resolvers: ((value: T) => void)[] = []
+
+  push(item: T) {
+    const resolve = this.resolvers.shift()
+    if (resolve) {
+      resolve(item)
+    } else {
+      this.queue.push(item)
+    }
+  }
+
+  async next(): Promise<T> {
+    if (this.queue.length > 0) {
+      return this.queue.shift()!
+    }
+    return new Promise((resolve) => {
+      this.resolvers.push(resolve)
+    })
+  }
+
+  async *[Symbol.asyncIterator]() {
+    while (true) {
+      yield await this.next()
+    }
+  }
+}
+
+// Usage
+const queue = new AsyncQueue<Message>()
+queue.push(message)
+
+for await (const msg of queue) {
+  console.log(msg)
+}
+```
+
+**File Reference:** `packages/opencode/src/util/queue.ts:1-19`
+
+#### Use Case 4: Complex Stateful Managers
+
+```typescript
+// ✅ ACCEPTABLE - When managing complex state machines
+export class ACPSessionManager {
+  private sessions: Map<string, ACPSession>
+  private connections: Map<string, WebSocket>
+
+  // Complex lifecycle management
+  async createSession(id: string) {...}
+  async handleMessage(id: string, msg: Message) {...}
+  async closeSession(id: string) {...}
+
+  // State machine logic
+  private transition(from: State, to: State) {...}
+}
+```
+
+**File Reference:** `packages/opencode/src/acp/session.ts:8`
+
+---
+
+## 3. Array Handling Standards
+
+### 3.1 Functional Methods (85% of operations)
+
+**Rule: Prefer map/filter/flatMap over for-loops**
+
+```typescript
+// ✅ GOOD - Functional chain with type inference
+const files = messages
+  .flatMap((x) => x.parts)
+  .filter((x): x is Patch => x.type === "patch") // Type guard maintains inference
+  .flatMap((x) => x.files)
+  .map((x) => path.relative(Instance.worktree, x))
+
+// ✅ GOOD - Parallel async operations
+const results = await Promise.all(
+  toolCalls.map(async (call) => {
+    return executeCall(call)
+  }),
+)
+
+// ✅ GOOD - Reduce for aggregation
+const totalAdditions = diffs.reduce((sum, x) => sum + x.additions, 0)
+
+// ✅ GOOD - Filter with type guards
+const agents = await Agent.list().then((x) => x.filter((a): a is Agent & { mode: "secondary" } => a.mode !== "primary"))
+
+// ✅ GOOD - Unique values
+const uniqueNames = Array.from(new Set(items.map((x) => x.name)))
+
+// ✅ GOOD - Sorting
+const sorted = items.toSorted((a, b) => a.timestamp - b.timestamp)
+```
+

+- `packages/opencode/src/session/prompt.ts` - Lines 192-200
+- `packages/opencode/src/session/summary.ts` - Lines 96-109
+
+### 3.2 For-Loops (15%, only when necessary)
+
+**Rule: Use for-loops only for:**
+
+1. Algorithm complexity (DP, graph traversal)
+2. Early exit requirements
+3. Sequential side effects
+4. Performance-critical iteration
+
+#### Pattern 1: Algorithm Complexity
+
+```typescript
+// ✅ GOOD - Dynamic programming (LCS algorithm)
+// packages/opencode/src/tool/edit.ts:175-176
+function lcs(a: string[], b: string[]): number[][] {
+  const dp: number[][] = Array(a.length + 1)
+    .fill(0)
+    .map(() => Array(b.length + 1).fill(0))
+
+  for (let i = 1; i <= a.length; i++) {
+    for (let j = 1; j <= b.length; j++) {
+      if (a[i - 1] === b[j - 1]) {
+        dp[i][j] = dp[i - 1][j - 1] + 1
+      } else {
+        dp[i][j] = Math.max(dp[i - 1][j], dp[i][j - 1])
+      }
+    }
+  }
+
+  return dp
+}
+```
+
+#### Pattern 2: Early Exit
+
+```typescript
+// ✅ GOOD - Break on condition
+// packages/opencode/src/session/revert.ts:31-40
+const patches = []
+for (const msg of all) {
+  if (msg.info.id === revert.messageID) break
+  for (const part of msg.parts) {
+    if (part.type === "patch") {
+      patches.push(part)
+    }
+  }
+}
+
+// ✅ GOOD - Find first match
+for (const file of files) {
+  if (await Filesystem.exists(file)) {
+    return file
+  }
+}
+```
+
+#### Pattern 3: Sequential Side Effects
+
+```typescript
+// ✅ GOOD - Sequential mutations
+for (const key of Object.keys(input.tools)) {
+  if (input.user.tools?.[key] === false || disabled.has(key)) {
+    delete input.tools[key]
+  }
+}
+
+// ✅ GOOD - Streaming output
+for (const line of lines) {
+  await stream.write(line)
+}
+```
+
+**File Reference:** `packages/opencode/src/tool/grep.ts:77`
+
+#### Pattern 4: Performance Critical
+
+```typescript
+// ✅ GOOD - Low-level iteration for performance
+for (let i = 0; i < buffer.length; i++) {
+  result += buffer[i] * multiplier
+}
+
+// Note: Profile before optimizing - functional methods are often fast enough
+```
+
+### 3.3 Type Guards on Filter
+
+**Rule: Use type guards to maintain type inference downstream**
+
+```typescript
+// ✅ GOOD - Type guard preserves type information
+const patches = messages.flatMap((msg) => msg.parts).filter((part): part is PatchPart => part.type === "patch")
+// patches is now PatchPart[], not Part[]
+
+// ❌ BAD - Loses type information
+const patches = messages.flatMap((msg) => msg.parts).filter((part) => part.type === "patch")
+// patches is still Part[], requires casting later
+
+// ✅ GOOD - Multiple type guards
+const validAgents = agents
+  .filter((a): a is Agent => a !== undefined)
+  .filter((a): a is Agent & { mode: "secondary" } => a.mode !== "primary")
+```
+
+**File Reference:** `packages/opencode/src/tool/task.ts:24,29`
+
+---
+
+## 4. Variable & Destructuring Standards
+
+### 4.1 Variable Declaration
+
+**Rule: Prefer `const` over `let`**
+
+```typescript
+// ✅ GOOD - Immutable with ternary
+const foo = condition ? 1 : 2
+const result = await (isValid ? processValid() : processInvalid())
+
+// ❌ BAD - Reassignment
+let foo
+if (condition) {
+  foo = 1
+} else {
+  foo = 2
+}
+
+// ✅ GOOD - Early return instead of reassignment
+function getValue(condition: boolean) {
+  if (condition) return 1
+  return 2
+}
+
+// ✅ ACCEPTABLE - let when mutation is necessary
+let accumulator = 0
+for (const item of items) {
+  accumulator += item.value
+}
+```
+
+**File Reference:** `AGENTS.md:56-68`
+
+### 4.2 Destructuring
+
+**Rule: Avoid unnecessary destructuring, preserve context with dot notation**
+
+```typescript
+// ✅ GOOD - Preserve context
+function process(session: Session) {
+  log.info("processing", { id: session.id, title: session.title })
+  return {
+    id: session.id,
+    status: session.status,
+    owner: session.owner
+  }
+}
+
+// ❌ BAD - Loses context, harder to read
+function process(session: Session) {
+  const { id, title, status, owner } = session
+  log.info("processing", { id, title })
+  return { id, status, owner }
+}
+
+// ✅ ACCEPTABLE - Destructuring when improving readability
+function renderUser({ name, email, avatar }: User) {
+  return `<div>${name} (${email})</div>`
+}
+
+// ✅ ACCEPTABLE - Destructuring array returns
+const [language, cfg, provider] = await Promise.all([...])
+```
+
+**File Reference:** `AGENTS.md:43-54`
+
+### 4.3 Variable Naming
+
+**Rule: Concise single-word names when descriptive**
+
+```typescript
+// ✅ GOOD
+const session = await Session.get(id)
+const user = await Auth.current()
+const messages = await Session.messages({ sessionID })
+
+// ❌ BAD - Unnecessary verbosity
+const currentSession = await Session.get(id)
+const currentlyAuthenticatedUser = await Auth.current()
+const sessionMessagesList = await Session.messages({ sessionID })
+
+// ✅ GOOD - Multi-word when single word is ambiguous
+const sessionID = params.id
+const userAgent = req.headers["user-agent"]
+const maxRetries = config.retries
+```
+
+---
+
+## 5. Control Flow Standards
+
+### 5.1 Early Returns
+
+**Rule: Avoid `else` statements, use early returns**
+
+```typescript
+// ✅ GOOD - Early returns
+function getStatus(session: Session) {
+  if (!session) return "not_found"
+  if (session.busy) return "busy"
+  if (session.error) return "error"
+  return "ready"
+}
+
+async function process(id: string) {
+  const session = await Session.get(id)
+  if (!session) return { error: "Not found" }
+
+  const result = await execute(session)
+  if (!result.success) return { error: result.message }
+
+  return { data: result.data }
+}
+
+// ❌ BAD - Else statements
+function getStatus(session: Session) {
+  if (!session) {
+    return "not_found"
+  } else {
+    if (session.busy) {
+      return "busy"
+    } else {
+      if (session.error) {
+        return "error"
+      } else {
+        return "ready"
+      }
+    }
+  }
+}
+```
+
+**File Reference:** `AGENTS.md:70-86`
+
+### 5.2 Guard Clauses
+
+```typescript
+// ✅ GOOD - Guard clauses at function start
+async function updateSession(id: string, data: UpdateData) {
+  if (!id) throw new Error("ID required")
+  if (!data) throw new Error("Data required")
+  if (data.title && data.title.length > 100) throw new Error("Title too long")
+
+  // Main logic here
+  const session = await Session.get(id)
+  await Session.update(id, data)
+  return session
+}
+```
+
+### 5.3 Switch Statements
+
+**Rule: Use exhaustive switch with default case**
+
+```typescript
+// ✅ GOOD - Exhaustive switch for stream handling
+for await (const value of stream.fullStream) {
+  switch (value.type) {
+    case "reasoning-start":
+      reasoningMap[value.id] = { id: generateId(), type: "reasoning", text: "" }
+      break
+
+    case "reasoning-delta":
+      if (value.id in reasoningMap) {
+        reasoningMap[value.id].text += value.text
+        await Session.updatePart({ delta: value.text })
+      }
+      break
+
+    case "tool-call":
+      await Session.updatePart({ state: { status: "running" } })
+      break
+
+    case "tool-result":
+      await Session.updatePart({ state: { status: "completed" } })

+## 6. Async & Concurrency Standards
+
+### 6.1 Parallel Execution (Default Pattern)
+
+**Rule: Use `Promise.all` for independent operations**
+
+```typescript
+// ✅ GOOD - Parallel independent operations
+const [language, cfg, provider, auth] = await Promise.all([
+  Provider.getLanguage(input.model),
+  Config.get(),
+  Provider.getProvider(input.model.providerID),
+  Auth.get(input.model.providerID),
+])
+
+// ✅ GOOD - Parallel array processing
+const results = await Promise.all(
+  items.map(async (item) => {
+    return processItem(item)
+  }),
+)
+
+// ❌ BAD - Sequential when independent
+const language = await Provider.getLanguage(input.model)
+const cfg = await Config.get() // Could run in parallel!
+const provider = await Provider.getProvider(input.model.providerID)
+const auth = await Auth.get(input.model.providerID)
+```
+
+**File Reference:** `packages/opencode/src/session/llm.ts:59`
+
+### 6.2 Sequential Operations
+
+**Rule: Chain when operations depend on previous results**
+
+```typescript
+// ✅ GOOD - Sequential dependency chain
+const session = await Session.create({ title: "New" })
+const message = await Session.addMessage(session.id, { content: "Hello" })
+const response = await LLM.stream({ sessionID: session.id, messageID: message.id })
+
+// ✅ GOOD - Promise chain for clarity
+const result = await Session.create({ title: "New" })
+  .then((session) => Session.addMessage(session.id, { content: "Hello" }))
+  .then((message) => LLM.stream({ messageID: message.id }))
+```
+
+### 6.3 Error Handling in Async
+
+**Rule: Prefer `.catch()` over try/catch when possible**
+
+```typescript
+// ✅ GOOD - Catch at call site
+const result = await operation().catch((error) => {
+  log.error("Operation failed", { error })
+  return defaultValue
+})
+
+// ✅ GOOD - Promise.all with error handling
+const results = await Promise.all(
+  items.map(async (item) => {
+    return processItem(item).catch((error) => {
+      log.error("Item failed", { item, error })
+      return null
+    })
+  }),
+)
+
+// ✅ ACCEPTABLE - try/catch for multiple operations
+try {
+  const session = await Session.create(input)
+  await Session.addMessage(session.id, message)
+  await EventBus.publish(Session.Event.Created, { session })
+  return session
+} catch (error) {
+  log.error("Session creation failed", { error })
+  throw error
+}
+
+// ❌ AVOID - try/catch for single operation
+try {
+  const result = await operation()
+  return result
+} catch (error) {
+  log.error(error)
+  throw error
+}
+// Better:
+const result = await operation().catch((error) => {
+  log.error(error)
+  throw error
+})
+```
+
+### 6.4 Concurrent Worker Pattern
+
+```typescript
+// ✅ GOOD - Controlled concurrency
+export async function work<T>(concurrency: number, items: T[], fn: (item: T) => Promise<void>) {
+  const pending = [...items]
+
+  await Promise.all(
+    Array.from({ length: concurrency }, async () => {
+      while (true) {
+        const item = pending.pop()
+        if (item === undefined) return
+        await fn(item)
+      }
+    }),
+  )
+}
+
+// Usage
+await work(3, files, async (file) => {
+  await processFile(file)
+})
+```

+## 10. State Management Standards
+
+### 10.1 Per-Instance State Isolation
+
+**Rule: All state must be isolated per working directory**
+
+```typescript
+// packages/opencode/src/project/instance.ts
+
+export namespace Instance {
+  // Current working directory
+  export let directory = process.cwd()
+
+  // Git worktree root
+  export let worktree = directory
+
+  // Project ID
+  export let id = "unknown"
+
+  // Create state scoped to current instance
+  export function state<S>(
+    init: () => S | Promise<S>,
+    dispose?: (state: Awaited<S>) => Promise<void>,
+  ): () => Awaited<S> {
+    return State.create(
+      () => Instance.directory, // Key by directory
+      init,
+      dispose,
+    )
+  }
+}
+
+// packages/opencode/src/project/state.ts
+
+const recordsByKey = new Map<string, Map<Function, Entry>>()
+
+interface Entry {
+  state: any
+  dispose?: (state: any) => Promise<void>
+}
+
+export function create<S>(
+  root: () => string,
+  init: () => S | Promise<S>,
+  dispose?: (state: Awaited<S>) => Promise<void>,
+): () => Awaited<S> {
+  return () => {
+    const key = root()
+
+    // Get or create entries for this key
+    let entries = recordsByKey.get(key)
+    if (!entries) {
+      entries = new Map<Function, Entry>()
+      recordsByKey.set(key, entries)
+    }
+
+    // Get or initialize state
+    const exists = entries.get(init)
+    if (exists) {
+      return exists.state as Awaited<S>
+    }
+
+    const state = init()
+    entries.set(init, { state, dispose })
+
+    return state as Awaited<S>
+  }
+}
+
+// Dispose all state for a key
+export async function dispose(key: string) {
+  const entries = recordsByKey.get(key)
+  if (!entries) return
+
+  await Promise.all(
+    Array.from(entries.values()).map(async (entry) => {
+      if (entry.dispose) {
+        const state = await entry.state
+        await entry.dispose(state)
+      }
+    }),
+  )
+
+  recordsByKey.delete(key)
+}

+
+### 10.2 State Initialization Pattern
+
+```typescript
+// ✅ GOOD - Lazy initialization with disposal
+const state = Instance.state(
+  async () => {
+    log.info("initializing LSP clients")
+
+    const cfg = await Config.get()
+    const servers: Record<string, LSPServer.Info> = {}
+    const clients: LSPClient.Info[] = []
+
+    // Initialize servers
+    for (const [id, server] of Object.entries(LSPServer)) {
+      if (cfg.lsp?.[id]?.enabled !== false) {
+        servers[id] = server
+      }
+    }
+
+    return {
+      servers,
+      clients,
+      broken: new Set<string>(),
+      spawning: new Map<string, Promise<LSPClient.Info | undefined>>(),
+    }
+  },
+  async (state) => {
+    log.info("disposing LSP clients")
+
+    // Cleanup all clients
+    await Promise.all(
+      state.clients.map(async (client) => {
+        try {
+          await client.shutdown()
+        } catch (error) {
+          log.error("failed to shutdown client", { client: client.id, error })
+        }
+      }),
+    )
+  },
+)
+
+// Access state
+const lspState = state()
+lspState.clients.push(newClient)
+```
+
+### 10.3 Global State (Rare)
+
+**Rule: Avoid global state, use per-instance state instead**
+
+```typescript
+// ❌ AVOID - Global mutable state
+const sessions = new Map<string, Session>()
+
+export function addSession(session: Session) {
+  sessions.set(session.id, session)
+}
+
+// ✅ PREFER - Per-instance state
+const state = Instance.state(async () => ({
+  sessions: new Map<string, Session>(),
+}))
+
+export function addSession(session: Session) {
+  state().sessions.set(session.id, session)
+}
+
+// ✅ ACCEPTABLE - Truly global state (user config, auth tokens)
+export namespace Global {
+  export namespace Path {
+    export const home = os.homedir()
+    export const config = path.join(home, ".config", "opencode")
+    export const data = path.join(home, ".local", "share", "opencode")
+    export const cache = path.join(home, ".cache", "opencode")
+  }
+}
+```
+

+
+## 11. Event Bus Standards
+
+### 11.1 Event Definition
+
+```typescript
+// packages/opencode/src/bus/event.ts
+
+export namespace BusEvent {
+  export interface Definition<Properties extends z.ZodType = any> {
+    type: string
+    properties: Properties
+  }
+
+  export function define<Properties extends z.ZodType>(type: string, properties: Properties): Definition<Properties> {
+    return { type, properties }
+  }
+}
+
+// Usage: Define events for a service
+export namespace Session {

+        }),
+        respond: z.function(),
+      }),
+    ),
+  }
+}
+```
+
+### 11.2 Publishing Events
+
+```typescript
+// packages/opencode/src/bus/index.ts
+
+export namespace Bus {
+  const state = Instance.state(async () => ({
+    subscriptions: new Map<string, Set<Handler>>(),
+  }))
+
+  type Handler = (payload: EventPayload) => void | Promise<void>
+
+  interface EventPayload {
+    type: string
+    properties: any
+  }
+
+  export async function publish<Definition extends BusEvent.Definition>(

+    properties: z.output<Definition["properties"]>,
+  ): Promise<void> {
+    const payload: EventPayload = {
+      type: def.type,
+      properties,
+    }
+
+    const pending: Promise<void>[] = []
+
+    // Notify specific subscribers
+    const specific = state().subscriptions.get(def.type)
+    if (specific) {
+      for (const handler of specific) {
+        pending.push(Promise.resolve(handler(payload)))
+      }
+    }
+
+    // Notify wildcard subscribers
+    const wildcard = state().subscriptions.get("*")
+    if (wildcard) {
+      for (const handler of wildcard) {
+        pending.push(Promise.resolve(handler(payload)))
+      }
+    }
+
+    // Also publish to global bus (for cross-instance communication)
+    GlobalBus.emit("event", {
+      directory: Instance.directory,
+      payload,
+    })
+
+    await Promise.all(pending)
+  }
+}
+
+// Usage: Publish an event
+await Bus.publish(Session.Event.Created, {
+  info: {
+    id: "session-123",
+    title: "New Session",
+    created: Date.now(),
+  },
+})
+
+await Bus.publish(Session.Event.Updated, {
+  info: updatedSession,
+  changes: { title: "Updated Title" },
+})
+```
+
+**File Reference:** `packages/opencode/src/bus/index.ts:41-64`
+
+### 11.3 Subscribing to Events
+
+```typescript
+// packages/opencode/src/bus/index.ts
+
+export namespace Bus {
+  export function subscribe<Definition extends BusEvent.Definition>(
+    def: Definition | "*",
+    handler: (payload: { type: string; properties: z.output<Definition["properties"]> }) => void | Promise<void>,
+  ): Disposable {
+    const key = typeof def === "string" ? def : def.type
+
+    let subs = state().subscriptions.get(key)
+    if (!subs) {
+      subs = new Set()
+      state().subscriptions.set(key, subs)
+    }
+
+    subs.add(handler)
+
+    return {
+      [Symbol.dispose]: () => {
+        subs?.delete(handler)
+        if (subs?.size === 0) {
+          state().subscriptions.delete(key)
+        }
+      },
+    }
+  }
+}
+
+// Usage: Subscribe to specific events
+const subscription = Bus.subscribe(Session.Event.Created, async (event) => {
+  log.info("session created", { id: event.properties.info.id })
+  await notifyUser(`New session: ${event.properties.info.title}`)
+})
+
+// Unsubscribe
+subscription[Symbol.dispose]()
+
+// Or use disposable pattern
+{
+  using sub = Bus.subscribe(Session.Event.Updated, handleUpdate)
+
+  // Automatically unsubscribes when scope exits
+}
+
+// Subscribe to all events
+Bus.subscribe("*", (event) => {
+  log.debug("event", { type: event.type, properties: event.properties })
+})
+```
+
+### 11.4 Event-Driven Communication Pattern
+
+```typescript
+// Service A: Publish events
+export namespace FileWatcher {
+  export const Event = {
+    Updated: BusEvent.define(
+      "file.updated",
+      z.object({
+        file: z.string(),
+        event: z.enum(["add", "change", "unlink"]),
+      }),
+    ),
+  }
+
+  async function watch(directory: string) {
+    const watcher = chokidar.watch(directory)
+
+    watcher.on("change", async (file) => {
+      await Bus.publish(Event.Updated, {
+        file,
+        event: "change",
+      })
+    })
+  }
+}
+
+// Service B: React to events
+export namespace LSP {
+  export async function initialize() {
+    // Subscribe to file changes
+    Bus.subscribe(FileWatcher.Event.Updated, async (event) => {
+      if (event.properties.event === "change") {
+        await notifyClientsOfChange(event.properties.file)
+      }
+    })
+  }
+
+  async function notifyClientsOfChange(file: string) {
+    const clients = state().clients.filter((c) => c.watchesFile(file))
+    await Promise.all(clients.map((c) => c.didChangeTextDocument({ uri: file })))
+  }
+}
+
+// Service C: Also react to same events
+export namespace Session {
+  export async function initialize() {
+    Bus.subscribe(FileWatcher.Event.Updated, async (event) => {
+      // Invalidate cached file contents
+      await invalidateFileCache(event.properties.file)
+    })
+  }
+}
+```

+## 12. Configuration Management Standards
+
+### 12.1 Configuration Precedence
+
+**Order (Low → High priority):**
+

+## 14. Error Handling Standards
+
+### 14.1 Named Errors (Preferred)
+
+```typescript
+// packages/opencode/src/util/error.ts
+
+import { NamedError } from "@opencode-ai/util/error"
+import z from "zod"
+
+// Define typed errors

+  "PermissionError",
+  z.object({
+    message: z.string(),
+    action: z.string(),

+  }),
+)
+
+// Usage: Throw typed error
+throw NotFoundError.create({
+  message: "Session not found",
+  resource: "session",
+  id: sessionID,
+})
+
+// Usage: Catch and check type
+try {
+  await operation()
+} catch (error) {
+  if (NotFoundError.is(error)) {
+    log.warn("resource not found", {
+      resource: error.data.resource,
+      id: error.data.id,
+    })
+    return null
+  }
+
+  if (PermissionError.is(error)) {

+    })
+    throw error
+  }
+
+  // Unknown error
+  log.error("unexpected error", { error })
+  throw error
+}
+```
+
+**File Reference:** `packages/opencode/src/storage/storage.ts:17-22`
+
+### 14.2 Custom Error Classes (When Needed)
+
+```typescript
+// ✅ GOOD - Error with additional context
+export class BusyError extends Error {
+  constructor(public readonly sessionID: string) {
+    super(`Session ${sessionID} is busy`)
+    this.name = "BusyError"
+  }
+}
+
+// Usage
+throw new BusyError(sessionID)
+
+// Catching
+try {
+  await process(sessionID)
+} catch (error) {
+  if (error instanceof BusyError) {
+    log.info("session busy, retrying", { sessionID: error.sessionID })
+    await retry()
+  }
+}
+```
+
+**File Reference:** `packages/opencode/src/session/index.ts:494`
+
+### 14.3 Result Pattern (for Tools)
+
+```typescript
+// ✅ GOOD - Never throw in tool execution
+export const ReadTool = Tool.define("read", {
+  async execute(args, context) {
+    try {
+      const content = await Bun.file(args.filePath).text()
+
+      return {
+        output: content,
+        title: `Read ${path.basename(args.filePath)}`,
+      }
+    } catch (error) {
+      return {
+        output: `Error reading file: ${error.message}`,
+        title: "Read Failed",
+        metadata: {
+          error: true,
+          message: error.message,
+        },
+      }
+    }
+  },
+})
+
+// ✅ GOOD - Result type for fallible operations
+export type Result<T, E = Error> = { success: true; value: T } | { success: false; error: E }
+
+export async function operation(): Promise<Result<Data>> {
+  try {
+    const data = await fetchData()
+    return { success: true, value: data }
+  } catch (error) {
+    return { success: false, error }
+  }
+}
+
+// Usage
+const result = await operation()
+if (result.success) {
+  console.log(result.value)
+} else {
+  log.error("operation failed", { error: result.error })
+}
+```
+
+### 14.4 Error Context
+
+```typescript
+// ✅ GOOD - Rich error context
+class OperationError extends Error {
+  constructor(
+    message: string,
+    public readonly context: {
+      operation: string
+      input: unknown
+      timestamp: number
+      sessionID?: string
+    }
+  ) {
+    super(message)
+    this.name = "OperationError"
+  }
+}
+
+// Usage
+try {
+  await processData(input)
+} catch (error) {
+  throw new OperationError(
+    "Failed to process data",
+    {
+      operation: "processData",
+      input,
+      timestamp: Date.now(),
+      sessionID: context.sessionID
+    }
+  )
+}
+
+// Logging with context
+catch (error) {
+  if (error instanceof OperationError) {
+    log.error("operation failed", {
+      operation: error.context.operation,
+      sessionID: error.context.sessionID,
+      error: error.message
+    })
+  }
+}
+```
+
+---
+
+## 15. Type System Standards
+
+### 15.1 Zod Schemas (Primary)
+
+**Rule: Use Zod for runtime validation, derive TypeScript types from schemas**
+
+```typescript
+// ✅ GOOD - Schema-first approach
+export namespace Session {
+  export const Info = z.object({
+    id: z.string(),
+    title: z.string(),
+    projectID: z.string(),
+    modelID: z.string().optional(),
+    permission: z.enum(["allow", "ask", "deny"]),
+    time: z.object({
+      created: z.number(),
+      updated: z.number(),
+    }),
+  })
+
+  // Derive TypeScript type from schema
+  export type Info = z.infer<typeof Info>
+
+  // Use in functions
+  export const create = fn(Info.pick({ title: true, projectID: true }).partial(), async (input): Promise<Info> => {
+    // Implementation
+  })
+}
+
+// ❌ BAD - Type-first approach (no runtime validation)
+export interface SessionInfo {
+  id: string
+  title: string
+  projectID: string
+}
+
+export function create(input: Partial<SessionInfo>): SessionInfo {
+  // No validation! Runtime errors possible
+}
+```
+
+### 15.2 Type Inference
+
+**Rule: Rely on type inference, avoid explicit annotations**
+
+```typescript
+// ✅ GOOD - Let TypeScript infer
+const session = await Session.create({ title: "New" })
+const messages = session.messages.filter((m) => m.role === "user")
+const ids = messages.map((m) => m.id)
+
+// ❌ BAD - Unnecessary annotations
+const session: Session.Info = await Session.create({ title: "New" })
+const messages: Message[] = session.messages.filter((m) => m.role === "user")
+const ids: string[] = messages.map((m) => m.id)
+
+// ✅ ACCEPTABLE - Annotation for clarity in complex scenarios
+const messages: Message[] = await fetchMessages().then((msgs): Message[] => {
+  return msgs.filter((m) => m.deleted !== true)
+})
+```
+
+**File Reference:** `AGENTS.md:15`
+
+### 15.3 Avoid `any`
+
+```typescript
+// ❌ BAD
+function process(data: any) {
+  return data.value.toString()
+}
+
+// ✅ GOOD - Use unknown and validate
+function process(data: unknown) {
+  if (typeof data !== "object" || data === null) {
+    throw new Error("Expected object")
+  }
+
+  if (!("value" in data)) {
+    throw new Error("Missing value property")
+  }
+
+  return String(data.value)
+}
+
+// ✅ BEST - Use Zod schema
+const DataSchema = z.object({
+  value: z.union([z.string(), z.number()]),
+})
+
+function process(data: unknown) {
+  const validated = DataSchema.parse(data)
+  return String(validated.value)
+}
+```
+
+**File Reference:** `AGENTS.md:12`
+
+### 15.4 Type Guards
+
+```typescript
+// ✅ GOOD - Type guards for narrowing
+function isMessage(value: unknown): value is Message {
+  return typeof value === "object" && value !== null && "id" in value && "role" in value && typeof value.id === "string"
+}
+
+// Usage
+if (isMessage(data)) {
+  console.log(data.id) // TypeScript knows data is Message
+}
+
+// ✅ GOOD - Type guards in filter
+const messages = items.filter((item): item is Message => isMessage(item)).map((msg) => msg.id)
+
+// ✅ GOOD - Discriminated unions
+type Part =
+  | { type: "text"; text: string }
+  | { type: "file"; data: Buffer; mimeType: string }
+  | { type: "patch"; files: string[]; diff: string }
+
+function handle(part: Part) {
+  switch (part.type) {
+    case "text":
+      console.log(part.text) // TypeScript knows: text part
+      break
+    case "file":
+      console.log(part.mimeType) // TypeScript knows: file part
+      break
+    case "patch":
+      console.log(part.files) // TypeScript knows: patch part
+      break
+    default:
+      const _exhaustive: never = part
+      throw new Error("Unhandled part type")
+  }
+}
+```
+
+---
+
+## 16. Import Organization Standards
+
+### 16.1 Import Order
+
+```typescript
+// 1. Zod and validation libraries
+import z from "zod"
+
+// 2. Node.js built-ins
+import path from "path"
+import fs from "fs/promises"
+import os from "os"
+
+// 3. External packages (alphabetical)
+import { mergeDeep, sortBy, unique } from "remeda"
+import chokidar from "chokidar"
+import fuzzysort from "fuzzysort"
+
+// 4. Internal packages (@opencode-ai/*)
+import { NamedError } from "@opencode-ai/util/error"
+
+// 5. Project utilities (../util/*)
+import { Log } from "../util/log"
+import { Lock } from "../util/lock"
+import { fn } from "../util/fn"
+
+// 6. Project services (../<service>/*)
+import { Config } from "../config/config"
+import { Storage } from "../storage/storage"
+import { Bus } from "../bus"
+
+// 7. Relative imports (same directory)
+import { Session } from "./session"
+import { MessageV2 } from "./message-v2"
+```
+
+### 16.2 Import Style
+
+```typescript
+// ✅ GOOD - Named imports
+import { create, update, get } from "./session"
+import { Log, type LogOptions } from "./util/log"
+
+// ❌ AVOID - Default imports (except for external packages)
+import session from "./session"
+
+// ✅ GOOD - Namespace imports for large APIs
+import * as Session from "./session"
+
+// ✅ GOOD - Type-only imports
+import type { Session } from "./session"
+import { type Config, loadConfig } from "./config"
+```
+
+### 16.3 Circular Dependency Prevention
+
+```typescript
+// ❌ BAD - Circular dependency
+// file-a.ts
+import { funcB } from "./file-b"
+export function funcA() {
+  return funcB()
+}
+
+// file-b.ts
+import { funcA } from "./file-a"
+export function funcB() {
+  return funcA()
+}
+
+// ✅ GOOD - Extract shared code
+// shared.ts
+export function shared() {
+  return 42
+}
+
+// file-a.ts
+import { shared } from "./shared"
+export function funcA() {
+  return shared()
+}
+
+// file-b.ts
+import { shared } from "./shared"
+export function funcB() {
+  return shared()
+}
+```
+
+---
+
+## 17. Naming Conventions
+
+### 17.1 Functions & Variables
+
+```typescript
+// ✅ camelCase for functions and variables
+const sessionID = "abc123"
+const userAgent = "opencode/1.0"
+const maxRetries = 3
+
+async function processMessage(messageID: string) {}
+async function createSession() {}
+```
+
+### 17.2 Types & Interfaces
+
+```typescript
+// ✅ PascalCase for types, interfaces, and classes
+type SessionInfo = {
+  id: string
+  title: string
+}
+
+interface Message {
+  id: string
+  content: string
+}
+
+class BusyError extends Error {}
+
+namespace Session {
+  export type Info = z.infer<typeof Info>
+}
+```
+
+### 17.3 Constants
+
+```typescript
+// ✅ SCREAMING_SNAKE_CASE for true constants
+const MAX_RETRY_ATTEMPTS = 3
+const DEFAULT_TIMEOUT = 5000
+const API_BASE_URL = "https://api.example.com"
+
+// ✅ camelCase for configuration values
+const maxRetries = config.retries ?? 3
+const defaultModel = config.model?.id ?? "gpt-4"
+```
+
+### 17.4 Namespaces
+
+```typescript
+// ✅ PascalCase for namespaces
+export namespace Session {}
+export namespace Storage {}
+export namespace FileWatcher {}
+```
+
+### 17.5 Files
+
+```typescript
+// ✅ kebab-case for files
+// session-manager.ts
+// message-processor.ts
+// file-watcher.ts
+
+// ✅ Single word when possible
+// session.ts
+// storage.ts
+// config.ts
+```
+
+---
+
+## 18. Testing Standards
+
+### 18.1 Principles
+
+1. **Avoid mocks** - Test actual implementation
+2. **No logic duplication** - Don't reimplement logic in tests
+3. **Use Bun test runner** - `bun test`
+
+**File Reference:** `AGENTS.md:108-111`
+
+### 18.2 Test Structure
+
+```typescript
+// packages/opencode/src/addons/serialize.test.ts
+
+import { expect, test, describe } from "bun:test"
+import { serialize, deserialize } from "./serialize"
+
+describe("serialize", () => {
+  test("preserves Date objects", () => {
+    const input = { date: new Date("2024-01-01") }
+    const serialized = serialize(input)
+    const deserialized = deserialize(serialized)
+
+    expect(deserialized.date).toBeInstanceOf(Date)
+    expect(deserialized.date.toISOString()).toBe("2024-01-01T00:00:00.000Z")
+  })
+
+  test("preserves Set objects", () => {
+    const input = { set: new Set([1, 2, 3]) }
+    const serialized = serialize(input)
+    const deserialized = deserialize(serialized)
+
+    expect(deserialized.set).toBeInstanceOf(Set)
+    expect(Array.from(deserialized.set)).toEqual([1, 2, 3])
+  })
+
+  test("handles nested structures", () => {
+    const input = {
+      map: new Map([["key", { date: new Date("2024-01-01") }]]),
+      array: [new Set([1, 2])],
+    }
+    const serialized = serialize(input)
+    const deserialized = deserialize(serialized)
+
+    expect(deserialized.map).toBeInstanceOf(Map)
+    expect(deserialized.map.get("key")?.date).toBeInstanceOf(Date)
+    expect(deserialized.array[0]).toBeInstanceOf(Set)
+  })
+})
+```
+
+**File Reference:** `packages/opencode/src/addons/serialize.test.ts`
+
+### 18.3 Test Commands
+
+```bash
+# Run all tests
+bun test
+
+# Run specific test file
+bun test src/util/queue.test.ts
+
+# Run tests matching pattern
+bun test --test-name-pattern "serialize"
+
+# Watch mode
+bun test --watch
+
+# Coverage
+bun test --coverage
+```
+
+**File Reference:** `packages/opencode/AGENTS.md` - Build/Test Commands
+
+### 18.4 Integration Tests
+
+```typescript
+import { test, expect, beforeAll, afterAll } from "bun:test"
+import { Session } from "./session"
+import { Storage } from "./storage"
+
+let sessionID: string
+
+beforeAll(async () => {
+  // Setup: Create test session
+  const session = await Session.create({ title: "Test Session" })
+  sessionID = session.id
+})
+
+afterAll(async () => {
+  // Cleanup: Delete test session
+  await Session.delete(sessionID)
+})
+
+test("create and retrieve session", async () => {
+  const session = await Session.get(sessionID)
+
+  expect(session).toBeDefined()
+  expect(session.id).toBe(sessionID)
+  expect(session.title).toBe("Test Session")
+})
+
+test("update session", async () => {
+  await Session.update(sessionID, { title: "Updated" })
+
+  const session = await Session.get(sessionID)
+  expect(session.title).toBe("Updated")
+})
+```
+
+---
+
+## 19. Documentation Standards
+
+### 19.1 Code Comments
+
+**Rule: Comment WHY, not WHAT**
+
+```typescript
+// ✅ GOOD - Explains why
+// Cache header separately to enable 2-part prompt caching
+if (system.length > 2 && system[0] === header) {
+  system.length = 0
+  system.push(header, rest.join("\n"))
+}
+
+// Prevent race condition: lock before checking existence
+using _ = await Lock.write(filepath)
+if (await Filesystem.exists(filepath)) {
+  await fs.rm(filepath)
+}
+
+// ❌ BAD - States the obvious
+// Push the item to the array
+items.push(item)
+
+// Set the title property
+session.title = "New Title"
+```
+
+### 19.2 JSDoc (For Exported APIs)
+
+````typescript
+/**
+ * Execute a function with a file lock to prevent concurrent access.
+ *
+ * The lock is automatically released when the function completes or throws.
+ * Locks are queued and processed in order.
+ *
+ * @param filepath - Absolute path to the file to lock
+ * @param fn - Function to execute while holding the lock
+ * @returns The result of the function
+ *
+ * @example
+ * ```typescript
+ * await withLock("/path/to/file", async () => {
+ *   const content = await Bun.file("/path/to/file").text()
+ *   await Bun.write("/path/to/file", content + "\n")
+ * })
+ * ```
+ */
+export async function withLock<T>(filepath: string, fn: () => Promise<T>): Promise<T>

+
+## 20. Schema Definition Standards
+
+### 20.1 Drizzle Schema (Database)
+
+**Rule: Use snake_case for field names to match SQL conventions**
+
+```typescript
+// ✅ GOOD - snake_case fields
+const sessionTable = sqliteTable("session", {
+  id: text().primaryKey(),
+  project_id: text().notNull(),
+  created_at: integer().notNull(),
+  updated_at: integer().notNull(),
+})
+
+// ❌ BAD - camelCase requires explicit column names
+const sessionTable = sqliteTable("session", {
+  id: text("id").primaryKey(),
+  projectID: text("project_id").notNull(),
+  createdAt: integer("created_at").notNull(),
+  updatedAt: integer("updated_at").notNull(),
+})
+```
+
+**File Reference:** `AGENTS.md:88-106`
+
+### 20.2 Zod Schema
+
+```typescript
+// ✅ GOOD - Consistent field naming
+export const SessionInfo = z.object({
+  id: z.string(),
+  projectID: z.string(), // camelCase for TypeScript
+  title: z.string(),
+  permission: z.enum(["allow", "ask", "deny"]),
+  time: z.object({
+    created: z.number(),
+    updated: z.number(),
+  }),
+})
+
+// ✅ GOOD - Schema composition
+export const CreateSessionInput = SessionInfo.pick({
+  title: true,
+  projectID: true,
+}).partial()
+
+export const UpdateSessionInput = SessionInfo.partial().required({
+  id: true,
+})
+
+// ✅ GOOD - Schema extension
+export const SessionWithMessages = SessionInfo.extend({
+  messages: z.array(MessageInfo),
+})
+```
+
+---
+
+## 21. Dependency Management Standards
+
+### 21.1 Bun Runtime Preference
+
+**Rule: Use Bun APIs when available**
+
+```typescript
+// ✅ GOOD - Bun APIs
+const content = await Bun.file(filepath).text()
+await Bun.write(filepath, content)
+const json = await Bun.file(filepath).json()
+
+const proc = Bun.spawn(["ls", "-la"], {
+  cwd: directory,
+  stdout: "pipe",
+})
+
+// ❌ AVOID - Node.js fs when Bun alternative exists
+import fs from "fs/promises"
+const content = await fs.readFile(filepath, "utf-8")
+await fs.writeFile(filepath, content)
+```
+
+**File Reference:** `AGENTS.md:14`
+
+### 21.2 Package Installation

+# Add dependency
+bun add package-name
+
+# Add dev dependency
+bun add -d package-name

+```
+
+### 21.3 Version Management
+
+```json
+// package.json
+{
+  "dependencies": {
+    "zod": "^3.22.4", // Allow patch and minor updates
+    "remeda": "1.30.0", // Pin exact version for critical deps

+
+## 23. Performance Standards
+
+### 23.1 Lazy Initialization
+
+```typescript
+// ✅ GOOD - Lazy state initialization
+const state = Instance.state(async () => {
+  // Only initialize when first accessed
+  const config = await Config.get()
+  return { config, clients: [] }
+})
+
+// Access only when needed
+if (needsClient) {
+  const client = state().clients[0]
+}
+
+// ✅ GOOD - Lazy loading of heavy dependencies
+const lazyModule = lazy(async () => {
+  return import("./heavy-module")
+})
+
+// Load only when needed
+const module = await lazyModule()
+```
+
+### 23.2 Caching
+
+```typescript
+// ✅ GOOD - Cache expensive operations
+const cache = new Map<string, Data>()
+
+async function getData(id: string): Promise<Data> {
+  const cached = cache.get(id)
+  if (cached) return cached
+
+  const data = await fetchData(id)
+  cache.set(id, data)
+  return data
+}
+
+// ✅ GOOD - Time-based cache invalidation
+const cache = new Map<string, { data: Data; expires: number }>()
+
+async function getData(id: string): Promise<Data> {
+  const cached = cache.get(id)
+  if (cached && Date.now() < cached.expires) {
+    return cached.data
+  }
+
+  const data = await fetchData(id)
+  cache.set(id, {
+    data,
+    expires: Date.now() + 60_000, // 1 minute
+  })
+  return data
+}
+```
+
+### 23.3 Debouncing
+
+```typescript
+// ✅ GOOD - Debounce high-frequency events
+function debounce<T extends (...args: any[]) => any>(fn: T, delay: number): (...args: Parameters<T>) => void {
+  let timer: Timer | undefined
+
+  return (...args: Parameters<T>) => {
+    if (timer) clearTimeout(timer)
+    timer = setTimeout(() => {
+      fn(...args)
+      timer = undefined
+    }, delay)
+  }
+}
+
+// Usage
+const debouncedSave = debounce(async (content: string) => {
+  await save(content)
+}, 500)
+
+// Only saves after 500ms of inactivity
+input.on("change", (content) => {
+  debouncedSave(content)
+})
+```
+
+### 23.4 Streaming
+
+```typescript
+// ✅ GOOD - Stream large responses
+export async function* streamMessages(sessionID: string) {
+  const files = await Storage.list(Storage.path("messages", sessionID), "*.json")
+
+  for (const file of files) {
+    const message = await Storage.read<Message>(file)
+    yield message
+  }
+}
+
+// Usage
+for await (const message of streamMessages(sessionID)) {
+  process(message)
+}
+```
+
+---
+
+## 24. Security Standards
+
+### 24.1 Input Validation
+
+```typescript
+// ✅ GOOD - Validate all external input
+export const handleRequest = fn(
+  z.object({
+    sessionID: z.string().regex(/^session-[a-z0-9]{10}$/),
+    content: z.string().max(100_000),
+    metadata: z.record(z.unknown()).optional(),
+  }),
+  async (input) => {
+    // Input is validated, safe to use
+    return process(input)
+  },
+)
+
+// ✅ GOOD - Validate file paths
+function validatePath(filepath: string) {
+  const normalized = path.normalize(filepath)
+  const absolute = path.resolve(normalized)
+
+  // Prevent directory traversal
+  if (!absolute.startsWith(Instance.worktree)) {
+    throw new Error("Path outside worktree")
+  }
+
+  return absolute
+}
+```
+
+### 24.2 Permission Checks
+
+```typescript
+// ✅ GOOD - Check permissions before sensitive operations
+async function readFile(filepath: string, context: Context) {
+  // Validate path
+  const safe = validatePath(filepath)
+
+  // Check permission
+  const permission = await PermissionNext.evaluate("read", safe, context.agent.permission)
+
+  if (permission.action === "deny") {
+    throw PermissionError.create({
+      message: "Permission denied",
+      action: "read",
+      resource: safe,
+    })
+  }
+
+  if (permission.action === "ask") {
+    const allowed = await context.ask({
+      type: "permission",
+      message: `Read file ${path.basename(safe)}?`,
+      actions: ["allow", "deny"],
+    })
+
+    if (!allowed) {
+      throw PermissionError.create({
+        message: "User denied permission",
+        action: "read",
+        resource: safe,
+      })
+    }
+  }
+
+  // Permission granted, perform operation
+  return Bun.file(safe).text()
+}
+```
+
+### 24.3 Secrets Management
+
+```typescript
+// ✅ GOOD - Load secrets from environment
+export namespace Auth {
+  export async function get(providerID: string): Promise<string | undefined> {
+    const key = `OPENCODE_${providerID.toUpperCase()}_API_KEY`
+    return process.env[key]
+  }
+}
+
+// ❌ AVOID - Hardcoded secrets
+const API_KEY = "sk-abc123..."
+
+// ❌ AVOID - Logging secrets
+log.info("api key", { key: apiKey })
+
+// ✅ GOOD - Redact secrets in logs
+log.info("api request", { key: apiKey.slice(0, 8) + "..." })
+```
+
+### 24.4 Command Injection Prevention
+
+```typescript
+// ❌ BAD - Command injection vulnerability
+const output = await $`ls ${userInput}`.text()
+
+// ✅ GOOD - Use array syntax (prevents injection)
+const proc = Bun.spawn(["ls", userInput], {
+  stdout: "pipe",
+})
+const output = await new Response(proc.stdout).text()
+
+// ✅ GOOD - Validate input
+const sanitized = userInput.replace(/[^a-zA-Z0-9_-]/g, "")
+const proc = Bun.spawn(["ls", sanitized])
+```
+
+---
+
+## Summary: Key Principles
+
+1. **Single-word function names** unless multi-word necessary (95%+ adherence)
+2. **Namespaces over classes** for code organization (only 5 classes in 206 files)
+3. **Functional array methods** over for-loops (85/15 split)
+4. **Parallel execution by default** via `Promise.all`
+5. **Lock mechanisms** prevent race conditions (reader-writer locks, file locks)
+6. **Per-instance state isolation** for multi-project support
+7. **Event-driven architecture** via pub/sub bus
+8. **Zod validation** for all inputs via `fn()` wrapper
+9. **Disposable resources** with `using` keyword for automatic cleanup
+10. **Bun runtime preference** for file I/O and process spawning
+11. **Inline values once, extract when reusable**
+12. **Named errors** over throw strings
+13. **Avoid mocks in tests**, test actual implementation
+14. **Layered config** with clear precedence (7 levels)
+15. **Graceful disposal** for all stateful services
+16. **Prefer `const` over `let`** - use ternaries instead of reassignment
+17. **Avoid `else` statements** - use early returns
+18. **Avoid destructuring** - preserve context with dot notation
+19. **Type inference** - avoid explicit annotations unless necessary
+20. **Avoid `any` type** - use `unknown` with validation
+21. **Comment WHY, not WHAT** - explain reasoning, not obvious operations
+22. **Schema-first approach** - define Zod schemas, derive TS types
+23. **Reader-writer locks** for concurrent access
+24. **System prompt caching** - maintain 2-part structure for efficiency
+25. **Context compaction** at 75% token threshold

 # Context Compaction (Minimization)
 
 **Purpose**: Compress verbose content into minimal viable information
 
-**Last Updated**: 2026-01-06
+**Last Updated**: 2026-02-15
 
 ---
 
-## The Compaction Process
+## Core Idea
 
 Transform verbose explanations → core concepts following MVI principle.
 
-**Formula**:
-```
-Verbose Content (100+ lines)
-  ↓ Extract Core
-Core Concept (1-3 sentences)
-  ↓ Extract Key Points
-Key Points (3-5 bullets)
-  ↓ Extract Example
-Minimal Example (<10 lines)
-  ↓ Add Reference
-Link to Full Docs
-  ↓ Result
-Compact File (<100 lines)
-```
+**Formula**: Verbose Content → Core Concept (1-3 sentences) → Key Points (3-5 bullets) → Minimal Example (<10 lines) → Reference Link → Compact File
 
 ---
 
-## Compression Techniques
+## 5 Compression Techniques
 
 ### 1. Extract Core Concept
-**From**: Paragraphs of explanation
-**To**: 1-3 sentences capturing essence
-
-**Example**:
-```markdown
-BEFORE (verbose):
-"React Hooks are a new addition to React 16.8 that let you use state 
-and other React features without writing a class. They're functions that 
-let you "hook into" React state and lifecycle features from function 
-components. Hooks don't work inside classes — they let you use React 
-without classes. You can also create your own Hooks to reuse stateful 
-behavior between different components..."
-
-AFTER (compact):
-"Hooks let you use state and lifecycle in function components without 
-classes. They're functions that hook into React features (useState, 
-useEffect, etc)."
-```
-
-**Rule**: If you can't explain it in 3 sentences, you don't understand it yet. Simplify further.
-
----
+**From**: Paragraphs → **To**: 1-3 sentences  
+**Rule**: If you can't explain it in 3 sentences, simplify further.
 
 ### 2. Bulletize Key Points
-**From**: Long paragraphs
-**To**: 3-5 bullet points
-
-**Example**:
-```markdown
-BEFORE:
-"When using hooks, there are several important rules to follow. First, 
-only call hooks at the top level of your function, never inside loops, 
-conditions, or nested functions. Second, only call hooks from React 
-function components or custom hooks. Third, hooks should be called in 
-the same order every render..."
-
-AFTER:
-**Key Points**:
-- Call hooks at top level only (not in loops/conditions)
-- Call from function components or custom hooks only
-- Must be called in same order every render
-- Names should start with "use" (convention)
-```
-
+**From**: Long paragraphs → **To**: 3-5 bullet points  
 **Rule**: Each bullet = one key fact. No sub-bullets.
 
----
-
 ### 3. Minimize Examples
-**From**: Full implementations
-**To**: Smallest working example (<10 lines)
-
-**Example**:
-```markdown
-BEFORE (50 lines):
-import React, { useState, useEffect } from 'react'
-import axios from 'axios'
-
-function UserProfile({ userId }) {
-  const [user, setUser] = useState(null)
-  const [loading, setLoading] = useState(true)
-  const [error, setError] = useState(null)
-  
-  useEffect(() => {
-    const fetchUser = async () => {
-      try {
-        setLoading(true)
-        const response = await axios.get(`/api/users/${userId}`)
-        setUser(response.data)
-        setError(null)
-      } catch (err) {
-        setError(err.message)
-        setUser(null)
-      } finally {
-        setLoading(false)
-      }
-    }
-    
-    fetchUser()
-  }, [userId])
-  
-  if (loading) return <div>Loading...</div>
-  if (error) return <div>Error: {error}</div>
-  if (!user) return <div>No user found</div>
-  
-  return (
-    <div>
-      <h1>{user.name}</h1>
-      <p>{user.email}</p>
-    </div>
-  )
-}
-
-AFTER (8 lines):
-```js
-const [count, setCount] = useState(0)
-
-useEffect(() => {
-  document.title = `Count: ${count}`
-}, [count]) // Re-run when count changes
-
-return <button onClick={() => setCount(count + 1)}>
-  Clicked {count} times
-</button>
-```
-
-**Rule**: Show the simplest case that demonstrates the concept. Link to full examples.
-
----
+**From**: Full implementations → **To**: Smallest working example (<10 lines)  
+**Rule**: Show the simplest case. Link to full examples.
 
 ### 4. Replace Repetition with References
-**From**: Same info repeated in multiple places
-**To**: Define once, reference with links
-
-**Example**:
-```markdown
-BEFORE:
-# File A
-Authentication uses JWT tokens. JWT tokens are JSON Web Tokens that...
-
-# File B
-For auth, we use JWT tokens. JWT tokens are JSON Web Tokens that...
-
-# File C
-The JWT token system (JSON Web Tokens) allows us to...
-
-AFTER:
-# concepts/jwt.md
-"JWT (JSON Web Token) is a stateless authentication method..."
-
-# Other files
-See concepts/jwt.md for details.
-```
-
+**From**: Same info repeated → **To**: Define once, reference with links  
 **Rule**: Say it once in concepts/, reference everywhere else.
 
----
-
 ### 5. Convert Prose to Tables
-**From**: Paragraphs listing things
-**To**: Scannable tables
-
-**Example**:
-```markdown
-BEFORE:
-"There are several important lifecycle methods. componentDidMount runs 
-after mounting, componentDidUpdate runs after updates, componentWillUnmount 
-runs before unmounting..."
-
-AFTER:
-| Method | When It Runs |
-|--------|--------------|
-| componentDidMount | After mount |
-| componentDidUpdate | After update |
-| componentWillUnmount | Before unmount |
-```
-
+**From**: Paragraphs listing things → **To**: Scannable tables  
 **Rule**: If listing >3 items, use a table or bullets.

 ## Compaction Checklist
 
-Before finalizing a context file:
-
 - [ ] Core concept is 1-3 sentences?
 - [ ] Key points are 3-5 bullets (no sub-bullets)?
 - [ ] Example is <10 lines of code?
 - [ ] No repeated explanations?
 - [ ] Reference link added for deep dive?
-- [ ] File is <200 lines total?
+- [ ] File is under line limit?
 - [ ] Can be scanned in <30 seconds?
 
-If any "no", compress further.

-## Common Bloat Patterns
-
-### Bloat: Over-Explaining
-```markdown
-❌ "This is important because it allows you to manage state in a more 
-efficient way, which can lead to better performance and cleaner code..."
-
-✅ "Manages state efficiently"
-```
-
-### Bloat: Historical Context
-```markdown
-❌ "Before React 16.8, we used class components. Then hooks were 
-introduced to solve several problems with classes..."
-
-✅ Skip history unless critical. Just explain current approach.
-```
-
-### Bloat: Multiple Examples
-```markdown
-❌ Example 1: useState with counter
-   Example 2: useState with string
-   Example 3: useState with object
-   Example 4: useState with array...
+## Common Bloat Patterns to Remove
 
-✅ Show ONE simple example. Link to more.
-```
-
-### Bloat: Implementation Details
-```markdown
-❌ "The internal implementation uses a fiber architecture with a 
-reconciliation algorithm that diffs the virtual DOM..."
-
-✅ Skip internal details. Just show how to use it.
-```
+| Bloat Type | ❌ Avoid | ✅ Use Instead |
+|------------|---------|---------------|
+| Over-Explaining | "This is important because it allows you to manage state in a more efficient way..." | "Manages state efficiently" |
+| Historical Context | "Before React 16.8, we used class components..." | Skip history unless critical |
+| Multiple Examples | Example 1, 2, 3, 4... | ONE simple example + link |
+| Implementation Details | "The internal implementation uses a fiber architecture..." | Skip internals, show usage |

-</workflow>
+### 1. Determine Function
+Ask: Is this a concept, example, guide, lookup, or error?  
+→ Place in correct folder
 
----
+### 2. Apply Template
+Use standard template for file type (see templates.md)
 
-## File Naming Conventions
+### 3. Apply MVI
+- Core: 1-3 sentences
+- Key points: 3-5 bullets
+- Example: <10 lines
+- Reference: Link to docs
 
-### Concepts
-**Format**: `{topic}.md`
-**Examples**:
-- `authentication.md`
-- `state-management.md`
-- `mvi-principle.md`
+### 4. Validate Size
+Ensure file under limit. If not, split or reference external.
 
-**Rule**: Lowercase, hyphenated, describes the concept
+### 5. Add Cross-References
+Link to related concepts/, examples/, guides/, errors/
 
----
-
-### Examples
-**Format**: `{what-it-demonstrates}.md`
-**Examples**:
-- `jwt-auth-example.md`
-- `react-hooks-example.md`
-- `api-call-example.md`
-
-**Rule**: End with `-example.md`, describes what it shows
+### 6. Update Navigation
+Add entry to navigation.md in parent directory
 
 ---
 
-### Guides
-**Format**: `{action-being-done}.md`
-**Examples**:
-- `setting-up-auth.md`
-- `deploying-api.md`
-- `migrating-to-v2.md`
+## File Naming Conventions
 
-**Rule**: Gerund form (verbs ending in -ing), describes the task
+| Type | Format | Example |
+|------|--------|---------|
+| Concept | `{concept-name}.md` | `authentication.md` |
+| Example | `{example-name}.md` | `jwt-example.md` |
+| Guide | `{action-name}.md` | `creating-agents.md` |
+| Lookup | `{reference-name}.md` | `commands.md` |
+| Error | `{error-category}.md` | `auth-errors.md` |
 
----
+**Rules**:
+- Use kebab-case (lowercase with hyphens)
+- Be descriptive but concise
+- Avoid redundant category in name (not `concept-authentication.md`)
 
-### Lookup
-**Format**: `{what-is-referenced}.md`
-**Examples**:
-- `cli-commands.md`
-- `file-locations.md`
-- `api-endpoints.md`
+---
 
-**Rule**: Plural noun, describes the reference type
+## Standard Metadata (Frontmatter)
 
----
+```html
+<!-- Context: {path} | Priority: {level} | Version: {X.Y} | Updated: {YYYY-MM-DD} -->
+```
 
-### Errors
-**Format**: `{framework-or-topic}-errors.md`
-**Examples**:
-- `react-errors.md`
-- `nextjs-build-errors.md`
-- `auth-errors.md`
+**Priority levels**: critical, high, medium, low
 
-**Rule**: End with `-errors.md`, group by framework/topic (NOT one file per error)
+**When to use**:
+- critical: Core system files, always needed
+- high: Frequently referenced, important patterns
+- medium: Useful but not essential
+- low: Nice-to-have, rarely needed
 
 ---
 
-## Standard Metadata
+## File Size Limits
 
-Every context file MUST start with:
-
-```markdown
-# {Type}: {Name}
+| File Type | Max Lines |
+|-----------|-----------|
+| Concept | 100 |
+| Example | 80 |
+| Guide | 150 |
+| Lookup | 100 |
+| Error | 150 |
 
-**Purpose**: [1 sentence describing what this file contains]
-
-**Last Updated**: {YYYY-MM-DD}
+**Enforcement**: Strict. If over limit, split into multiple files or reference external docs.
 
 ---
-```
 
-**Example**:
-```markdown
-# Concept: JWT Authentication
+## Cross-Reference Guidelines
 
-**Purpose**: Stateless authentication using signed JSON Web Tokens
+**Format**: `See {type}/{filename}.md for {what}`
 
-**Last Updated**: 2026-01-06
+**Examples**:
+- `See concepts/authentication.md for JWT details`
+- `See examples/jwt-example.md for working code`
+- `See errors/auth-errors.md for troubleshooting`
 
----
-```
+**Best practices**:
+- Link to related concepts
+- Link to examples from guides
+- Link to errors from guides
+- Create bidirectional links when relevant
 
 ---
 
-## Priority Assignment
+## Navigation Update Process
 
-When adding files to README.md, assign priority:
+When creating a file, update parent `navigation.md`:
 
-| Priority | When to Use |
-|----------|-------------|
-| **critical** | Must understand to work on project. Core concepts. |
-| **high** | Commonly used. Important patterns. |
-| **medium** | Occasionally needed. Reference material. |
-| **low** | Rarely used. Edge cases. |
-
-**Example**:
 ```markdown
-### Concepts
 | File | Description | Priority |
 |------|-------------|----------|
-| [auth.md](concepts/auth.md) | Authentication system | critical |
-| [caching.md](concepts/caching.md) | Cache strategy | high |
-| [logging.md](concepts/logging.md) | Logging patterns | medium |
-```
-
----
-
-## Cross-Reference Guidelines
-
-### When to Link
-
-Link to related files when:
-- Concept uses another concept
-- Example demonstrates a concept
-- Guide references concepts/examples
-- Error relates to specific concept
-
-### How to Link
-
-**Format**: `**Related**: type/file.md`
-
-**Example**:
-```markdown
-**Related**:
-- concepts/authentication.md
-- examples/jwt-auth-example.md
-- errors/auth-errors.md
+| new-file.md | Brief description | high |
 ```
 
-**Rule**: Use relative paths from current location
-
----
-
-## README.md Update Process
-
-When creating a new file:
-
-1. **Open category README.md**
-2. **Find correct section** (Concepts/Examples/Guides/Lookup/Errors)
-3. **Add table row**:
-   ```markdown
-   | [file.md](folder/file.md) | Description | priority |
-   ```
-4. **Sort by priority** (critical → high → medium → low)
-5. **Update "Last Updated"** date at top
+**Keep navigation**:
+- Alphabetical within priority groups
+- Grouped by priority (critical → high → medium → low)
+- Descriptions <10 words

 ## Common Creation Mistakes
 
-### ❌ Mistake 1: Wrong Folder
-```
-development/authentication.md  ❌ (flat structure)
-
-development/concepts/authentication.md  ✅ (function-based)
-```
-
-### ❌ Mistake 2: Too Verbose
-```markdown
-# Concept: JWT
-
-[500 lines of explanation, examples, edge cases...]  ❌
-
-# Concept: JWT
-
-**Core Idea**: Stateless auth with signed tokens (1-3 sentences)  ✅
-```
-
-### ❌ Mistake 3: Missing README Update
-```
-Created: concepts/new-topic.md
-README.md: Not updated  ❌
-
-Created: concepts/new-topic.md
-README.md: Updated with navigation entry  ✅
-```
-
-### ❌ Mistake 4: One Error Per File
-```
-errors/jwt-expired-error.md
-errors/jwt-invalid-error.md
-errors/jwt-missing-error.md  ❌ (too granular)
-
-errors/auth-errors.md  ✅ (grouped by topic)
-```
-
----
-
-## File Size Enforcement
-
-<rule id="size_enforcement" enforcement="strict">
-  If file exceeds line limit:
-  
-  1. First: Apply more compression (see compact.md)
-  2. If still too large: Split into multiple files
-  3. If logically can't split: Move details to external docs, keep summary
-  
-  DO NOT exceed 200 lines under any circumstance.
-</rule>
-
-**Example**:
-```markdown
-If concepts/authentication.md hits 250 lines:
-
-Option 1: Compress (apply MVI more strictly)
-Option 2: Split:
-  - concepts/authentication.md (core)
-  - concepts/jwt-tokens.md (specific type)
-  - concepts/oauth.md (another type)
-Option 3: Reference external:
-  - Keep 100-line summary in concepts/authentication.md
-  - Link to https://docs.company.com/auth (full details)
-```
+| Mistake | Fix |
+|---------|-----|
+| File too long | Split into multiple files or compress |
+| Missing frontmatter | Add HTML comment at top |
+| Wrong folder | Move to correct function folder |
+| No cross-references | Add links to related files |
+| Verbose explanations | Apply MVI compression |
+| Missing from navigation | Update navigation.md |

-## Decision Tree
-
-### Step 1: Is this repository-specific?
-
-**YES** → Use **Pattern A (Function-Based)**
-
-Examples:
-- `openagents-repo/` - OpenAgents Control repository work
-- `myproject-repo/` - Your project's repository
-
-**NO** → Continue to Step 2
-

-### Step 2: Does content span multiple technologies?
-
-**YES** → Use **Pattern B (Concern-Based)**
-
-Examples:
-- `development/` - Frontend, backend, data, infrastructure
-- `ui/` - Web, terminal, mobile (future)
-
-**NO** → Use **Pattern A (Function-Based)**
-
-Examples:
-- `content/` - Copywriting frameworks (single domain)
-- `product/` - Product management (single domain)
-
----
-
-### Step 3: Is there a natural hierarchy of concerns?
-
-**YES** → Use **Pattern B (Concern-Based)**
-
-Example hierarchy:
-```
-development/
-├── frontend/           # Concern
-│   ├── react/          # Tech
-│   └── vue/            # Tech

-
-**NO** → Use **Pattern A (Function-Based)**
-
----
-
-## Pattern A: Function-Based Organization
-
-### When to Use
-
-✅ Repository-specific context (e.g., `openagents-repo/`)
-✅ Single-domain content (e.g., `content/`, `product/`)
-✅ Content naturally groups by information type
-✅ Users need to find "how to do X" quickly
-
-### Structure

-
-**Why this works**:
-- Repository-specific (not general development)
-- Users need "how to add agent" (guide)
-- Users need "where is X file" (lookup)
-- Users need "fix this error" (errors)
-
----
-
-## Pattern B: Concern-Based Organization
-
-### When to Use
-
-✅ Multi-technology content (e.g., `development/`)
-✅ Content organized by "what you're doing" (concern)
-✅ Multiple approaches/technologies per concern
-✅ Need to support full-stack workflows

-    ├── sql-patterns/           # Approach
-    └── orm-patterns/           # Approach
-```
-
-**Why this works**:
-- Multi-technology (React, Vue, Node, Python, etc.)
-- Organized by concern (frontend, backend, data)
-- Then by approach (REST, GraphQL) or tech (Node.js, React)
-- Supports full-stack workflows
-
----
-
-## Hybrid Approach
-
-### When to Use
-
-✅ Category has both repository-specific AND multi-tech content
-✅ Need flexibility for different subcategories
-
-### Structure
-
-```
-{category}/
-├── navigation.md
-│
-├── {subcategory-A}/            # Function-based
-│   ├── concepts/
-│   ├── guides/
-│   └── examples/
-│
-└── {subcategory-B}/            # Concern-based
-    ├── {concern}/
-    │   ├── {approach}/
-    │   └── {tech}/
-```
-
-### Example: ui/
-
-```
-ui/
-├── navigation.md
-│
-├── web/                        # Platform (concern-based)
-│   ├── navigation.md
-│   ├── animation-patterns.md
-│   ├── ui-styling-standards.md
-│   └── design/
-│       ├── concepts/           # Function-based within
-│       └── examples/
-│
-└── terminal/                   # Platform (concern-based)
-    └── navigation.md
-```
-
-**Why this works**:
-- Top level: Platform-based (web, terminal, mobile)
-- Within platform: Mix of flat files + function folders
-- Flexible for different needs
-
----
-
-## Organizing by Concern vs Tech
-
-### Concern First, Then Tech
-
-**Use when**: Multiple technologies solve the same concern
-
-```
-backend/
-├── api-patterns/               # Concern: API design
-│   ├── rest-design.md          # Approach
-│   ├── graphql-design.md       # Approach
-│   └── grpc-patterns.md        # Approach
-├── nodejs/                     # Tech
-└── python/                     # Tech
-```
-
-**Why**: Principles (REST, GraphQL) are more important than implementation (Node, Python)
-
----
-
-### Tech First, Then Concern
-
-**Use when**: Technology dictates the approach
-
 ```
-frontend/
-├── react/                      # Tech
-│   ├── hooks-patterns.md       # Concern: state
-│   ├── component-architecture.md # Concern: structure
-│   └── tanstack/               # Sub-tech
-│       ├── query-patterns.md   # Concern: data fetching
-│       └── router-patterns.md  # Concern: routing
-└── vue/                        # Tech
+{concern}/
+├── {approach}/   # How you're doing it
+└── {tech}/       # What you're using
 ```
 
-**Why**: React patterns differ significantly from Vue patterns
+**Example**: `development/frontend/react/`, `ui/web/design/`
 
 ---
 
-## Specialized Navigation Files
-
-### When to Create
-
-✅ Concern spans multiple subcategories
-✅ Common workflows cross category boundaries
-✅ Users need task-focused routes
-
-### Examples
-
-**ui-navigation.md** (in `development/`):
-- Spans `development/frontend/` + `ui/web/`
-- Task: "I need to build a UI"
-- Routes to both code patterns and visual design
-
-**backend-navigation.md** (in `development/`):
-- Covers `backend/api-patterns/`, `backend/nodejs/`, `backend/authentication/`
-- Task: "I need to build an API"
-- Routes to approach, tech, and functional concerns
+## Decision Tree
 
-**fullstack-navigation.md** (in `development/`):
-- Covers frontend + backend + data
-- Task: "I need to build a full-stack app"
-- Shows common tech stacks (MERN, T3, etc.)
+| Question | Answer | Use Pattern |
+|----------|--------|-------------|
+| Is this repository-specific? | YES | **Pattern A** (Function-Based) |
+| Does content span multiple technologies? | YES | **Pattern B** (Concern-Based) |
+| Single domain/technology? | YES | **Pattern A** (Function-Based) |

-## Steps to Organize
+## Quick Steps to Organize
 
 ### 1. Audit Existing Content
-
-List all files:
-```bash
-find .opencode/context/{category} -name "*.md" | sort
-```
-
-Categorize each file:
-- What concern does it address?
-- What approach/tech does it cover?
-- What type of information? (concept, guide, example, etc.)
-
----
+- List all files
+- Identify natural groupings
+- Note overlaps/duplicates
 
 ### 2. Choose Pattern
-
-Use decision tree above to choose:
-- Pattern A (Function-Based)
-- Pattern B (Concern-Based)
-- Hybrid
-
----
+- Use decision tree above
+- Consider future growth
+- Check existing patterns in `.opencode/context/`
 
 ### 3. Create Directory Structure
-
-**For Pattern A**:
 ```bash
-mkdir -p {category}/{concepts,examples,guides,lookup,errors}
+mkdir -p {category}/{subcategory}
 ```
 
-**For Pattern B**:
-```bash
-mkdir -p {category}/{concern}/{approach}
-mkdir -p {category}/{concern}/{tech}
-```
-
----
-
 ### 4. Move Files
-
-Move files to appropriate locations:
-```bash
-mv {category}/old-file.md {category}/{concern}/{tech}/new-file.md
-```
-
-Rename for clarity:
-```bash
-mv code.md code-quality.md
-mv tests.md test-coverage.md
-```
-
----
+- Move files to new structure
+- Keep filenames descriptive
+- Follow naming conventions
 
 ### 5. Create Navigation Files
-
-Create `navigation.md` at each level:
-- Category level
-- Subcategory level
-- Specialized navigation (if needed)
-
-Follow navigation design guide (navigation-design.md)
-
----
+- Add `navigation.md` to each directory
+- Follow navigation template (see navigation-templates.md)
+- Keep to 200-300 tokens
 
 ### 6. Update References
-
-Find and update all cross-references:
-```bash
-grep -r "old-path" .opencode/context/
-# Update to new paths
-```
+- Update links in moved files
+- Update parent navigation.md
+- Test navigation paths

+## Enhanced Schema Support
+
+The CLI fully supports the enhanced task schema (v2.0) with:
+- **Line-number precision** - Context files with specific line ranges
+- **Domain modeling** - bounded_context, module, vertical_slice fields
+- **Contract tracking** - API/interface dependencies
+- **Design artifacts** - Figma, wireframes, mockups
+- **ADR references** - Architecture decision records
+- **Prioritization** - RICE/WSJF scores
+
+All enhanced fields are optional and backward compatible. See `../standards/enhanced-task-schema.md` for details.
+
+---
+
+## Planning Workflow Integration
+
+For multi-stage orchestration workflows, use these planning agents before task creation:
+
+| Agent | Purpose | Output |
+|-------|---------|--------|
+| **ArchitectureAnalyzer** | DDD bounded context identification | `.tmp/architecture/contexts.json` |
+| **StoryMapper** | User journey and story mapping | `.tmp/story-maps/map.json` |
+| **PrioritizationEngine** | RICE/WSJF scoring | `.tmp/backlog/prioritized.json` |
+| **ContractManager** | API contract definition | `.tmp/contracts/{service}.json` |
+| **ADRManager** | Architecture decision records | `docs/adr/` |
+
+These agents populate enhanced schema fields (bounded_context, contracts, related_adrs, rice_score, etc.) automatically.
+
+See `.opencode/context/core/workflows/multi-stage-orchestration.md` for the complete workflow.

+# Enhanced Task JSON Schema
+
+**Purpose**: Extended JSON schema for multi-stage orchestration with line-number precision, domain modeling, and prioritization
+
+**Version**: 2.0
+
+**Last Updated**: 2026-02-14
+
+**Backward Compatible**: Yes (all new fields are optional)
+
+---
+
+## Overview
+
+This schema extends the base task.json and subtask_NN.json schemas with:
+- **Line-number precision** for context and reference files
+- **Domain modeling** fields (bounded_context, module, vertical_slice)
+- **Contract tracking** for API/interface dependencies
+- **Design artifacts** linking
+- **ADR references** for architectural decisions
+- **Prioritization scores** (RICE, WSJF)
+- **Release planning** (release_slice)
+
+All enhancements are **optional** and backward compatible with existing task files.
+
+---
+
+## Enhanced task.json Schema
+
+### New Fields
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `bounded_context` | string | No | DDD bounded context (e.g., "authentication", "billing") |
+| `module` | string | No | Module/package name (e.g., "@app/auth", "payment-service") |
+| `vertical_slice` | string | No | Feature slice identifier (e.g., "user-registration", "checkout-flow") |
+| `contracts` | array | No | API/interface contracts this feature depends on or provides |
+| `design_components` | array | No | Design artifacts (Figma URLs, wireframes, mockups) |
+| `related_adrs` | array | No | Architecture Decision Records (ADR file paths or IDs) |
+| `rice_score` | object | No | RICE prioritization (Reach, Impact, Confidence, Effort) |
+| `wsjf_score` | object | No | WSJF prioritization (Business Value, Time Criticality, Risk Reduction, Job Size) |
+| `release_slice` | string | No | Release identifier (e.g., "v1.2.0", "Q1-2026", "MVP") |
+
+### Enhanced context_files and reference_files Format
+
+**Old format** (still supported):
+```json
+"context_files": [
+  ".opencode/context/core/standards/code-quality.md"
+]
+```
+
+**New format** (line-number precision):
+```json
+"context_files": [
+  {
+    "path": ".opencode/context/core/standards/code-quality.md",
+    "lines": "1-50",
+    "reason": "Pure function patterns for service layer"
+  },
+  {
+    "path": ".opencode/context/core/standards/security-patterns.md",
+    "lines": "120-145",
+    "reason": "JWT token validation rules"
+  }
+]
+```
+
+**Backward Compatibility**: Both formats are valid. Agents should handle both:
+- String format → read entire file
+- Object format → read specified lines only
+
+---
+
+## Enhanced subtask_NN.json Schema
+
+### New Fields
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `bounded_context` | string | No | Inherited from task.json or subtask-specific override |
+| `module` | string | No | Module this subtask modifies |
+| `vertical_slice` | string | No | Feature slice this subtask belongs to |
+| `contracts` | array | No | Contracts this subtask implements or depends on |
+| `design_components` | array | No | Design artifacts relevant to this subtask |
+| `related_adrs` | array | No | ADRs relevant to this subtask |

+
+---
+
+## Line-Number Precision Format
+
+### Purpose
+
+Reduce cognitive load by pointing agents to **exact sections** of large files instead of forcing them to read entire documents.
+
+### Format
+
+```json
+{
+  "path": "path/to/file.md",
+  "lines": "10-50",
+  "reason": "Why these lines matter"
+}
+```
+
+### Line Range Syntax
+
+- `"10-50"` - Lines 10 through 50 (inclusive)
+- `"1-20,45-60"` - Lines 1-20 AND 45-60 (multiple ranges)
+- Omit `lines` field to read entire file
+
+### Examples
+
+**Single range**:
+```json
+{
+  "path": ".opencode/context/core/standards/code-quality.md",
+  "lines": "53-95",
+  "reason": "Pure function and immutability patterns"
+}
+```
+
+**Multiple ranges**:
+```json
+{
+  "path": ".opencode/context/core/standards/security-patterns.md",
+  "lines": "1-25,120-145,200-220",
+  "reason": "JWT validation rules and token refresh patterns"
+}
+```
+
+**Entire file** (backward compatible):
+```json
+{
+  "path": ".opencode/context/core/standards/code-quality.md",
+  "reason": "All coding standards"
+}
+```
+
+**Legacy string format** (still supported):
+```json
+".opencode/context/core/standards/code-quality.md"
+```
+
+---
+
+## Backward Compatibility Rules
+
+### Rule 1: All new fields are optional
+
+Existing task.json and subtask_NN.json files remain valid without any changes.
+
+### Rule 2: Mixed formats allowed
+
+You can mix old and new formats in the same file:
+
+```json
+{
+  "context_files": [
+    ".opencode/context/core/standards/code-quality.md",
+    {
+      "path": ".opencode/context/core/standards/security-patterns.md",
+      "lines": "120-145",
+      "reason": "JWT validation"
+    }
+  ]
+}
+```
+
+### Rule 3: Agent handling
+
+Agents MUST support both formats:
+
+```typescript
+function loadContextFile(ref: string | ContextFileReference): string {
+  if (typeof ref === 'string') {
+    // Legacy format: read entire file
+    return readFile(ref);
+  } else {
+    // New format: read specified lines
+    const content = readFile(ref.path);
+    if (ref.lines) {
+      return extractLines(content, ref.lines);
+    }
+    return content;
+  }
+}
+```
+
+### Rule 4: Gradual migration
+
+Projects can adopt enhanced fields incrementally:
+1. Start with line-number precision for large files
+2. Add domain modeling fields (bounded_context, module) when needed
+3. Add prioritization scores when planning releases
+4. Add contracts/ADRs when formalizing architecture
+

+
+## Migration Guide
+
+### For TaskManager Agents
+
+When creating new tasks:
+
+1. **Use line-number precision for large files** (>100 lines):
+   ```json
+   {
+     "path": ".opencode/context/core/standards/code-quality.md",
+     "lines": "53-95",
+     "reason": "Pure function patterns"
+   }
+   ```
+
+2. **Add domain modeling fields** when known:
+   ```json
+   {
+     "bounded_context": "authentication",
+     "module": "@app/auth",
+     "vertical_slice": "user-login"
+   }
+   ```
+
+3. **Link design artifacts** for UI tasks:
+   ```json
+   {
+     "design_components": [
+       {
+         "type": "figma",
+         "url": "https://figma.com/...",
+         "description": "Login page mockups"
+       }
+     ]
+   }
+   ```
+
+4. **Reference ADRs** for architectural decisions:
+   ```json
+   {
+     "related_adrs": [
+       {
+         "id": "ADR-003",
+         "path": "docs/adr/003-jwt-authentication.md"
+       }
+     ]
+   }
+   ```
+
+### For Working Agents (CoderAgent, etc.)
+
+When reading tasks:
+
+1. **Handle both context file formats**:
+   ```typescript
+   const contextFiles = task.context_files || [];
+   for (const ref of contextFiles) {
+     if (typeof ref === 'string') {
+       // Read entire file
+       const content = await readFile(ref);
+     } else {
+       // Read specified lines
+       const content = await readFileLines(ref.path, ref.lines);
+       console.log(`Reading ${ref.path} (${ref.lines}): ${ref.reason}`);
+     }
+   }
+   ```
+
+2. **Use contract information** to understand dependencies:
+   ```typescript
+   const contracts = task.contracts || [];
+   const apiContracts = contracts.filter(c => c.type === 'api');
+   // Load API contract definitions before implementing
+   ```
+
+3. **Check ADRs** before making architectural decisions:
+   ```typescript
+   const adrs = task.related_adrs || [];
+   for (const adr of adrs) {
+     if (adr.path) {
+       const decision = await readFile(adr.path);
+       // Apply architectural constraints from ADR
+     }
+   }
+   ```

+## Migration to Enhanced Schema
+
+The enhanced schema adds powerful features while maintaining full backward compatibility:
+
+### When to Use Enhanced Schema
+
+Use `enhanced-task-schema.md` when you need:
+- **Line-number precision** - Point to specific sections of large files (reduces cognitive load)
+- **Domain modeling** - Track bounded contexts, modules, vertical slices
+- **Contract tracking** - Manage API/interface dependencies
+- **Design artifacts** - Link Figma, wireframes, mockups
+- **ADR references** - Connect architectural decisions to tasks
+- **Prioritization** - RICE/WSJF scoring for release planning
+
+### Migration Path
+
+1. **No changes required** - Existing task files work as-is
+2. **Gradual adoption** - Add enhanced fields incrementally:
+   - Start with line-number precision for large context files
+   - Add domain fields (bounded_context, module) when modeling architecture
+   - Add contracts when defining APIs
+   - Add prioritization scores when planning releases
+3. **Mixed formats** - You can mix old and new formats in the same file
+
+### Example: Adding Line-Number Precision
+
+**Old format** (still valid):
+```json
+"context_files": [
+  ".opencode/context/core/standards/code-quality.md"
+]
+```
+
+**New format** (enhanced):
+```json
+"context_files": [
+  {
+    "path": ".opencode/context/core/standards/code-quality.md",
+    "lines": "53-95",
+    "reason": "Pure function patterns for service layer"
+  }
+]
+```
+
+Both formats work. Agents handle both automatically.

+# Lightweight Context Handoff - Orchestrator Example
+
+## Complete Feature Implementation Using Context Index
+
+This document shows a complete orchestrator workflow using the lightweight context handoff pattern for implementing a JWT authentication system.
+
+---
+
+## Setup Phase
+
+### Step 1: Initialize Context Index
+
+```typescript
+import { createContextIndex } from './.opencode/skill/task-management/scripts/context-index';
+
+// Create lightweight index with initial context
+const result = createContextIndex('auth-system', {
+  contextFiles: [
+    '.opencode/context/core/standards/code-quality.md',
+    '(example: (example: .opencode/context/security/auth-patterns.md))',
+    '(example: (example: .opencode/context/architecture/ddd-patterns.md))',
+    '(example: (example: .opencode/context/core/story-mapping/guide.md))'
+  ],
+  referenceFiles: [
+    'src/auth/old-auth.ts',
+    'src/middleware/auth.middleware.ts'
+  ]
+});
+
+// Result: .tmp/context-index/auth-system.json created
+```
+
+**What's in the index:**
+```json
+{
+  "feature": "auth-system",
+  "created": "2026-02-15T10:00:00Z",
+  "updated": "2026-02-15T10:00:00Z",
+  "agents": {},
+  "contextFiles": [
+    ".opencode/context/core/standards/code-quality.md",
+    "(example: (example: .opencode/context/security/auth-patterns.md))",
+    "(example: (example: .opencode/context/architecture/ddd-patterns.md))",
+    "(example: (example: .opencode/context/core/story-mapping/guide.md))"
+  ],
+  "referenceFiles": [
+    "src/auth/old-auth.ts",
+    "src/middleware/auth.middleware.ts"
+  ]
+}
+```
+
+---
+
+## Stage 1: Architecture Analysis
+
+### Step 2: Get Context for ArchitectureAnalyzer
+
+```typescript
+import { getContextForAgent } from './.opencode/skill/task-management/scripts/context-index';
+
+const archContext = getContextForAgent('auth-system', 'ArchitectureAnalyzer');
+
+// Returns:
+{
+  feature: "auth-system",
+  agentType: "ArchitectureAnalyzer",
+  contextFiles: [
+    "(example: .opencode/context/architecture/ddd-patterns.md)"
+  ],
+  referenceFiles: [
+    "src/auth/old-auth.ts",
+    "src/middleware/auth.middleware.ts"
+  ],
+  agentOutputs: [],
+  metadata: {}
+}
+```
+
+**Key Point:** ArchitectureAnalyzer gets ONLY:
+- Architecture patterns context
+- Reference files to analyze
+- NO story mapping guide (not needed yet)
+- NO previous agent outputs (it's first)
+
+### Step 3: Delegate to ArchitectureAnalyzer
+
+```typescript
+task(
+  subagent_type="ArchitectureAnalyzer",
+  description="Analyze authentication system architecture",
+  prompt=`
+    Analyze the architecture for implementing JWT authentication.
+    
+    Context files to load:
+    - ${archContext.contextFiles[0]}
+    
+    Reference files to analyze:
+    - ${archContext.referenceFiles[0]}
+    - ${archContext.referenceFiles[1]}
+    
+    Identify:
+    - Bounded contexts
+    - Module boundaries
+    - Integration points
+    
+    Output: .tmp/architecture/auth-system/contexts.json
+  `
+);
+```
+
+### Step 4: ArchitectureAnalyzer Completes → Update Index
+
+```typescript
+import { addAgentOutput } from './.opencode/skill/task-management/scripts/context-index';
+
+// Read ArchitectureAnalyzer output
+const archOutput = JSON.parse(
+  fs.readFileSync('.tmp/architecture/auth-system/contexts.json', 'utf-8')
+);
+
+// Update index with output path and metadata
+addAgentOutput(
+  'auth-system',
+  'ArchitectureAnalyzer',
+  '.tmp/architecture/auth-system/contexts.json',
+  {
+    boundedContext: archOutput.primary_context,  // "authentication"
+    module: archOutput.module_name,              // "auth-service"
+    complexity: archOutput.complexity            // "medium"
+  }
+);
+```
+
+**Index now contains:**
+```json
+{
+  "feature": "auth-system",
+  "agents": {
+    "ArchitectureAnalyzer": {
+      "outputs": [".tmp/architecture/auth-system/contexts.json"],
+      "metadata": {
+        "boundedContext": "authentication",
+        "module": "auth-service",
+        "complexity": "medium"
+      },
+      "timestamp": "2026-02-15T10:05:00Z"
+    }
+  },
+  ...
+}
+```
+
+---
+
+## Stage 2: Story Mapping
+
+### Step 5: Get Context for StoryMapper
+
+```typescript
+const storyContext = getContextForAgent('auth-system', 'StoryMapper');
+
+// Returns:
+{
+  feature: "auth-system",
+  agentType: "StoryMapper",
+  contextFiles: [
+    "(example: .opencode/context/core/story-mapping/guide.md)"
+  ],
+  referenceFiles: [],
+  agentOutputs: [
+    ".tmp/architecture/auth-system/contexts.json"
+  ],
+  metadata: {
+    boundedContext: "authentication",
+    module: "auth-service",
+    complexity: "medium"
+  }
+}
+```
+
+**Key Point:** StoryMapper gets:
+- Story mapping guide (filtered from contextFiles)
+- ArchitectureAnalyzer output path (NOT full content)
+- Metadata from ArchitectureAnalyzer (small, useful data)
+- NO reference files (doesn't need source code)
+
+### Step 6: Delegate to StoryMapper
+
+```typescript
+task(
+  subagent_type="StoryMapper",
+  description="Create user story map for authentication",
+  prompt=`
+    Create a user story map for JWT authentication system.
+    
+    Context files to load:
+    - ${storyContext.contextFiles[0]}
+    
+    Previous agent outputs to read:
+    - ${storyContext.agentOutputs[0]}
+    
+    Metadata from ArchitectureAnalyzer:
+    - Bounded Context: ${storyContext.metadata.boundedContext}
+    - Module: ${storyContext.metadata.module}
+    
+    Create vertical slices for:
+    - User login
+    - Token refresh
+    - Logout
+    
+    Output: .tmp/story-maps/auth-system/map.json
+  `
+);
+```
+
+### Step 7: StoryMapper Completes → Update Index
+
+```typescript
+const storyOutput = JSON.parse(
+  fs.readFileSync('.tmp/story-maps/auth-system/map.json', 'utf-8')
+);
+
+addAgentOutput(
+  'auth-system',
+  'StoryMapper',
+  '.tmp/story-maps/auth-system/map.json',
+  {
+    verticalSlice: storyOutput.primary_slice,  // "user-login"
+    storyCount: storyOutput.stories.length     // 8
+  }
+);
+```
+
+---
+
+## Stage 3: Prioritization
+
+### Step 8: Get Context for PrioritizationEngine
+
+```typescript
+const prioContext = getContextForAgent('auth-system', 'PrioritizationEngine');
+
+// Returns:
+{
+  feature: "auth-system",
+  agentType: "PrioritizationEngine",
+  contextFiles: [],  // No prioritization context file in index
+  referenceFiles: [],
+  agentOutputs: [
+    ".tmp/story-maps/auth-system/map.json"
+  ],
+  metadata: {
+    verticalSlice: "user-login",
+    storyCount: 8
+  }
+}
+```
+
+**Key Point:** PrioritizationEngine gets:
+- StoryMapper output path (to read stories)
+- Metadata from StoryMapper
+- NO ArchitectureAnalyzer output (not needed)
+
+### Step 9: Delegate to PrioritizationEngine
+
+```typescript
+task(
+  subagent_type="PrioritizationEngine",
+  description="Prioritize authentication stories",
+  prompt=`
+    Prioritize user stories for authentication system.
+    
+    Story map to read:
+    - ${prioContext.agentOutputs[0]}
+    
+    Metadata:
+    - Vertical Slice: ${prioContext.metadata.verticalSlice}
+    - Story Count: ${prioContext.metadata.storyCount}
+    
+    Calculate RICE and WSJF scores.
+    Assign to release slices.
+    
+    Output: .tmp/planning/auth-system/prioritized.json
+  `
+);
+```
+
+### Step 10: PrioritizationEngine Completes → Update Index
+
+```typescript
+const prioOutput = JSON.parse(
+  fs.readFileSync('.tmp/planning/auth-system/prioritized.json', 'utf-8')
+);
+
+addAgentOutput(
+  'auth-system',
+  'PrioritizationEngine',
+  '.tmp/planning/auth-system/prioritized.json',
+  {
+    releaseSlice: prioOutput.release_slice,  // "v1.0.0"
+    avgRiceScore: prioOutput.avg_rice_score  // 6750
+  }
+);
+```
+
+---
+
+## Stage 4: Task Breakdown
+
+### Step 11: Get Context for TaskManager
+
+```typescript
+const taskContext = getContextForAgent('auth-system', 'TaskManager');
+
+// Returns:
+{
+  feature: "auth-system",
+  agentType: "TaskManager",
+  contextFiles: [
+    ".opencode/context/core/standards/code-quality.md"
+  ],
+  referenceFiles: [],
+  agentOutputs: [
+    ".tmp/architecture/auth-system/contexts.json",
+    ".tmp/story-maps/auth-system/map.json",
+    ".tmp/planning/auth-system/prioritized.json"
+  ],
+  metadata: {
+    ArchitectureAnalyzer: {
+      boundedContext: "authentication",
+      module: "auth-service"
+    },
+    StoryMapper: {
+      verticalSlice: "user-login",
+      storyCount: 8
+    },
+    PrioritizationEngine: {
+      releaseSlice: "v1.0.0",
+      avgRiceScore: 6750
+    }
+  }
+}
+```
+
+**Key Point:** TaskManager gets:
+- ALL previous agent outputs (needs full picture)
+- Metadata from ALL agents (for task.json population)
+- Coding standards (for subtask context_files)
+
+### Step 12: Delegate to TaskManager
+
+```typescript
+task(
+  subagent_type="TaskManager",
+  description="Break down authentication into subtasks",
+  prompt=`
+    Create task breakdown for JWT authentication system.
+    
+    Context files to load:
+    - ${taskContext.contextFiles[0]}
+    
+    Previous agent outputs to read:
+    - ${taskContext.agentOutputs[0]} (Architecture)
+    - ${taskContext.agentOutputs[1]} (Stories)
+    - ${taskContext.agentOutputs[2]} (Priorities)
+    
+    Metadata from previous agents:
+    ${JSON.stringify(taskContext.metadata, null, 2)}
+    
+    Create task.json and subtask_NN.json files.
+    Use metadata to populate enhanced fields.
+    
+    Output: .tmp/tasks/auth-system/
+  `
+);
+```
+
+### Step 13: TaskManager Completes → Update Index
+
+```typescript
+addAgentOutput(
+  'auth-system',
+  'TaskManager',
+  '.tmp/tasks/auth-system/task.json',
+  {
+    subtaskCount: 5,
+    parallelTasks: 2
+  }
+);
+```
+
+---
+
+## Stage 5: Implementation
+
+### Step 14: Get Context for CoderAgent
+
+```typescript
+const coderContext = getContextForAgent('auth-system', 'CoderAgent');
+
+// Returns:
+{
+  feature: "auth-system",
+  agentType: "CoderAgent",
+  contextFiles: [
+    ".opencode/context/core/standards/code-quality.md",
+    "(example: .opencode/context/security/auth-patterns.md)"
+  ],
+  referenceFiles: [],
+  agentOutputs: [
+    ".tmp/tasks/auth-system/task.json"
+  ],
+  metadata: {}
+}
+```
+
+**Key Point:** CoderAgent gets:
+- Coding standards and security patterns
+- TaskManager output (task.json)
+- NO architecture/story/priority outputs (not needed for coding)
+
+### Step 15: Delegate to CoderAgent (for each subtask)
+
+```typescript
+// Read task.json to get subtask list
+const taskJson = JSON.parse(
+  fs.readFileSync('.tmp/tasks/auth-system/task.json', 'utf-8')
+);
+
+// For each subtask
+for (let seq = 1; seq <= taskJson.subtask_count; seq++) {
+  const subtaskPath = `.tmp/tasks/auth-system/subtask_${seq.toString().padStart(2, '0')}.json`;
+  
+  task(
+    subagent_type="CoderAgent",
+    description=`Implement subtask ${seq}`,
+    prompt=`
+      Implement the subtask defined in: ${subtaskPath}
+      
+      Context files to load:
+      ${coderContext.contextFiles.map(f => `- ${f}`).join('\n')}
+      
+      Follow acceptance criteria exactly.
+      Run self-review before completion.
+    `
+  );
+}
+```
+

+
+## Summary: What Each Agent Received
+
+### ArchitectureAnalyzer
+```
+Context Files: 1 (architecture patterns)
+Reference Files: 2 (existing code)
+Agent Outputs: 0
+Total Files to Read: 3
+```
+
+### StoryMapper
+```
+Context Files: 1 (story mapping guide)
+Reference Files: 0
+Agent Outputs: 1 (ArchitectureAnalyzer)
+Total Files to Read: 2
+```
+
+### PrioritizationEngine
+```
+Context Files: 0
+Reference Files: 0
+Agent Outputs: 1 (StoryMapper)
+Total Files to Read: 1
+```
+
+### TaskManager
+```
+Context Files: 1 (code quality standards)
+Reference Files: 0
+Agent Outputs: 3 (all previous agents)
+Total Files to Read: 4
+```
+
+### CoderAgent
+```
+Context Files: 2 (code quality + security)
+Reference Files: 0
+Agent Outputs: 1 (TaskManager - subtask JSON)
+Total Files to Read: 3
+```
+
+---
+
+## Comparison: With vs Without Context Index
+
+### WITHOUT Context Index (Session Context Pattern)
+
+**Every agent receives:**
+```
+- Full session context.md (500+ lines)
+- All context files (10+ files)
+- All reference files
+- All previous agent outputs
+- Full decision history
+- Full progress tracking
+
+Total: 15+ files, 5000+ lines per agent
+```
+
+### WITH Context Index (Lightweight Pattern)
+
+**Each agent receives:**
+```
+ArchitectureAnalyzer: 3 files
+StoryMapper: 2 files
+PrioritizationEngine: 1 file
+TaskManager: 4 files
+CoderAgent: 3 files
+
+Average: 2.6 files per agent
+```
+
+**Reduction:** ~83% fewer files per agent
+
+---
+
+## Benefits Demonstrated
+
+### 1. Minimal Context Per Agent
+Each agent reads only what it needs, nothing more.
+
+### 2. Fast Handoffs
+Orchestrator just passes file paths, not content.
+
+### 3. Clear Dependencies
+Agent outputs are explicitly tracked and passed.
+
+### 4. Lightweight Index
+Index stays small (~200 lines JSON) even with 5 agents.
+
+### 5. Scalable
+Adding more agents doesn't bloat the index.
+
+### 6. Debuggable
+Easy to trace: "Which agent produced this file?"

+  const context = getContextForAgent(feature, agentType);
+  
+  // Delegate with minimal context
+  const result = task(
+    subagent_type=agentType,
+    description=`Execute ${agentType} for ${feature}`,
+    prompt=`
+      Context files: ${context.contextFiles.join(', ')}

+      Your task: ...
+    `
+  );
+  
+  // Update index with output
+  addAgentOutput(feature, agentType, outputPath, metadata);
+}
+```

+
+## When to Use This Pattern
+
+✅ **Use Lightweight Context Index when:**
+- Multi-agent orchestration (3+ agents)
+- Each agent has a specific role
+- Performance matters
+- Context bloat is a problem
+- Agents should be isolated
+
+❌ **Don't use when:**
+- Single agent session
+- Human needs to review context
+- Agents need full narrative history
+- Interactive feedback loops
+
+**Alternative:** Use `session-context-manager.ts` for human-readable tracking alongside context-index for agent coordination.

+# Lightweight Context Handoff Pattern
+
+## Problem
+
+**Context Fragmentation in Multi-Agent Orchestration**
+
+- Orchestrator needs to track full context across all agents
+- Subagents should only get what they need for their specific job
+- Current `session-context-manager.ts` passes too much context (entire session state)
+- Agents waste time reading irrelevant files
+- Context bloat slows down execution
+
+## Solution
+
+**Lightweight Context Index**
+
+- Orchestrator maintains a lightweight "context index" (just file paths and metadata)
+- Each subagent gets ONLY the specific files they need
+- Orchestrator reads agent outputs and updates the index
+- Index is a pointer system, not a content dump
+
+## Key Principle
+
+✅ **DO THIS:**
+```
+Orchestrator → Agent: "Here's the ONE file you need: .tmp/architecture/auth-system/contexts.json"
+```
+
+❌ **NOT THIS:**
+```
+Orchestrator → Agent: "Here's the entire session context with everything from all previous agents (5000 lines)"
+```
+
+---
+
+## Architecture
+
+### Context Index Structure
+
+```typescript
+{
+  feature: "auth-system",
+  created: "2026-02-15T10:00:00Z",
+  updated: "2026-02-15T10:30:00Z",
+  agents: {
+    "ArchitectureAnalyzer": {
+      outputs: [".tmp/architecture/auth-system/contexts.json"],
+      metadata: { 
+        boundedContext: "authentication", 
+        module: "auth-service" 
+      },
+      timestamp: "2026-02-15T10:05:00Z"
+    },
+    "StoryMapper": {
+      outputs: [".tmp/story-maps/auth-system/map.json"],
+      metadata: { 
+        verticalSlice: "user-login" 
+      },
+      timestamp: "2026-02-15T10:15:00Z"
+    }
+  },
+  contextFiles: [
+    ".opencode/context/core/standards/code-quality.md",
+    "(example: .opencode/context/security/auth-patterns.md)"
+  ],
+  referenceFiles: [
+    "src/auth/old-auth.ts"
+  ]
+}
+```
+
+### What Gets Stored
+
+**Lightweight (paths and metadata only):**
+- ✅ File paths to agent outputs
+- ✅ Small metadata objects (boundedContext, module, etc.)
+- ✅ Timestamps
+- ✅ Context file paths
+- ✅ Reference file paths
+
+**NOT stored (content stays in files):**
+- ❌ Full file contents
+- ❌ Large JSON blobs
+- ❌ Entire session history
+- ❌ Redundant context

+  }
+}
+```
+

+}
+```
+

+
+## Orchestrator Workflow Example
+
+### Complete Feature Implementation Flow
+
+```typescript
+import { 
+  createContextIndex, 
+  addAgentOutput, 
+  getContextForAgent 
+} from './context-index';
+
+// 1. Initialize context index
+createContextIndex('auth-system', {
+  contextFiles: [
+    '.opencode/context/core/standards/code-quality.md',
+    '(example: .opencode/context/security/auth-patterns.md)',
+    '(example: .opencode/context/architecture/patterns.md)'
+  ],
+  referenceFiles: [
+    'src/auth/old-auth.ts'
+  ]
+});
+
+// 2. Delegate to ArchitectureAnalyzer
+const archContext = getContextForAgent('auth-system', 'ArchitectureAnalyzer');
+// Pass ONLY: archContext.contextFiles + archContext.referenceFiles
+
+// 3. ArchitectureAnalyzer completes → Read output and update index
+addAgentOutput(
+  'auth-system',
+  'ArchitectureAnalyzer',
+  '.tmp/architecture/auth-system/contexts.json',
+  { boundedContext: 'authentication', module: 'auth-service' }
+);
+
+// 4. Delegate to StoryMapper
+const storyContext = getContextForAgent('auth-system', 'StoryMapper');
+// Pass ONLY: 
+//   - storyContext.contextFiles (story mapping guide)
+//   - storyContext.agentOutputs (ArchitectureAnalyzer output path)
+
+// 5. StoryMapper completes → Update index
+addAgentOutput(
+  'auth-system',
+  'StoryMapper',
+  '.tmp/story-maps/auth-system/map.json',
+  { verticalSlice: 'user-login' }
+);
+
+// 6. Delegate to PrioritizationEngine
+const prioContext = getContextForAgent('auth-system', 'PrioritizationEngine');
+// Pass ONLY:
+//   - prioContext.contextFiles (prioritization guide)
+//   - prioContext.agentOutputs (StoryMapper output path)
+
+// 7. Continue pattern through all agents...
+```
+
+### Key Pattern
+
+```typescript
+// For each agent:
+const context = getContextForAgent(feature, agentType);
+
+// Delegate with minimal context
+task(
+  subagent_type=agentType,
+  description="...",
+  prompt=`
+    Context files to load:
+    ${context.contextFiles.map(f => `- ${f}`).join('\n')}
+    
+    Previous agent outputs to read:
+    ${context.agentOutputs.map(f => `- ${f}`).join('\n')}
+    
+    Metadata from previous agents:
+    ${JSON.stringify(context.metadata, null, 2)}
+    
+    Your task: ...
+  `
+);
+
+// After agent completes, update index
+addAgentOutput(feature, agentType, outputPath, metadata);
+```
+

+
+## Comparison: Session Context vs Context Index
+
+### When to Use Session Context Manager
+
+**Use `session-context-manager.ts` when:**
+- ✅ Single long-running session with one agent
+- ✅ Need human-readable markdown summary
+- ✅ Want to track decisions and progress narratively
+- ✅ Session state needs to be reviewed by humans
+
+**Example:** Interactive feature development with user feedback loops
+
+### When to Use Context Index
+
+**Use `context-index.ts` when:**
+- ✅ Multi-agent orchestration with delegation
+- ✅ Need minimal context handoff between agents
+- ✅ Want to avoid context bloat
+- ✅ Agents should only see what they need
+- ✅ Performance matters (large features)
+
+**Example:** Automated feature pipeline (Architecture → Stories → Tasks → Code)
+
+### Comparison Table
+
+| Feature | Session Context | Context Index |
+|---------|----------------|---------------|
+| **Format** | Markdown (human-readable) | JSON (machine-readable) |
+| **Size** | Large (full content) | Small (paths only) |
+| **Audience** | Humans + Agents | Agents only |
+| **Context Passing** | Everything to everyone | Minimal per agent |
+| **Use Case** | Interactive sessions | Automated pipelines |
+| **Performance** | Slower (large files) | Faster (lightweight) |
+| **Tracking** | Decisions, progress, narrative | Outputs, metadata, pointers |
+
+### Can You Use Both?
+
+**Yes!** They solve different problems:
+
+```typescript
+// Create session context for human tracking
+createSession('auth-system', 'Implement JWT authentication', {
+  contextFiles: [...],
+  exitCriteria: [...]
+});
+
+// Create context index for agent coordination
+createContextIndex('auth-system', {
+  contextFiles: [...],
+  referenceFiles: [...]
+});
+
+// Session context = human-readable audit trail
+// Context index = efficient agent coordination
+```
+
+---
+
+## Benefits
+
+### For Orchestrator
+- ✅ Lightweight tracking (just paths and metadata)
+- ✅ Full visibility into all agent outputs
+- ✅ Easy to coordinate dependencies
+- ✅ Fast lookups
+
+### For Subagents
+- ✅ Minimal context (only what they need)
+- ✅ Faster execution (less reading)
+- ✅ Clear dependencies (explicit output paths)
+- ✅ No context bloat
+
+### For System
+- ✅ Scalable (index stays small)
+- ✅ Maintainable (clear separation of concerns)
+- ✅ Debuggable (trace agent outputs)
+- ✅ Composable (agents don't need to know about each other)
+
+---
+
+## Anti-Patterns
+
+### ❌ Passing Entire Index to Agents
+
+```typescript
+// BAD: Agent gets everything
+const index = getFullContext('auth-system');
+task(subagent_type="StoryMapper", prompt=JSON.stringify(index));
+```
+
+**Why bad:** Agent wastes time parsing irrelevant data
+
+### ❌ Embedding Content in Index
+
+```typescript
+// BAD: Storing full file contents
+addAgentOutput('auth-system', 'ArchitectureAnalyzer', outputPath, {
+  fullContent: fs.readFileSync(outputPath, 'utf-8') // DON'T DO THIS
+});
+```
+
+**Why bad:** Index becomes bloated, defeats the purpose
+
+### ❌ Skipping Index Updates
+
+```typescript
+// BAD: Agent completes but orchestrator doesn't update index
+task(subagent_type="ArchitectureAnalyzer", ...);
+// ... agent completes ...
+// (orchestrator forgets to call addAgentOutput)
+```
+
+**Why bad:** Next agent won't know about previous outputs
+
+### ❌ Using Index for Human Review
+
+```typescript
+// BAD: Expecting humans to read JSON index
+const index = getFullContext('auth-system');
+console.log("Review this:", JSON.stringify(index));
+```
+
+**Why bad:** Index is for machines, use session-context for humans
+
+---
+
+## Best Practices
+
+### 1. Update Index Immediately After Agent Completes
+
+```typescript
+// Agent completes
+const result = await task(subagent_type="ArchitectureAnalyzer", ...);
+
+// Immediately update index
+addAgentOutput(
+  'auth-system',
+  'ArchitectureAnalyzer',
+  '.tmp/architecture/auth-system/contexts.json',
+  { boundedContext: 'authentication' }
+);
+```
+
+### 2. Use Metadata for Small, Useful Data
+
+```typescript
+// GOOD: Small metadata that helps next agent
+addAgentOutput('auth-system', 'ArchitectureAnalyzer', outputPath, {
+  boundedContext: 'authentication',
+  module: 'auth-service',
+  complexity: 'medium'
+});
+
+// BAD: Large data that should stay in files
+addAgentOutput('auth-system', 'ArchitectureAnalyzer', outputPath, {
+  fullAnalysis: { /* 1000 lines of JSON */ }
+});
+```
+
+### 3. Let Agents Read Their Own Inputs
+
+```typescript
+// GOOD: Agent reads the file
+const context = getContextForAgent('auth-system', 'StoryMapper');
+task(
+  subagent_type="StoryMapper",
+  prompt=`Read architecture analysis: ${context.agentOutputs[0]}`
+);
+
+// BAD: Orchestrator reads and passes content
+const archOutput = fs.readFileSync('.tmp/architecture/...', 'utf-8');
+task(
+  subagent_type="StoryMapper",
+  prompt=`Here's the full architecture: ${archOutput}`
+);
+```
+
+### 4. Keep Context Files Focused
+
+```typescript
+// GOOD: Only relevant context files
+createContextIndex('auth-system', {
+  contextFiles: [
+    '(example: .opencode/context/security/auth-patterns.md)',
+    '.opencode/context/core/standards/code-quality.md'
+  ]
+});
+
+// BAD: Every context file in the project
+createContextIndex('auth-system', {
+  contextFiles: glob('.opencode/context/**/*.md') // Too much!
+});
+```
+
+---
+
+## CLI Usage
+
+### Create Index
+
+```bash
+npx ts-node context-index.ts create auth-system
+# ✅ Context index created for: auth-system
+#    Location: .tmp/context-index/auth-system.json
+```
+
+### Add Agent Output
+
+```bash
+npx ts-node context-index.ts add-output \
+  auth-system \
+  ArchitectureAnalyzer \
+  .tmp/architecture/auth-system/contexts.json \
+  '{"boundedContext":"authentication","module":"auth-service"}'
+# ✅ Added ArchitectureAnalyzer output: .tmp/architecture/auth-system/contexts.json
+```
+
+### Get Context for Agent
+
+```bash
+npx ts-node context-index.ts get-context auth-system StoryMapper
+# {
+#   "feature": "auth-system",
+#   "agentType": "StoryMapper",
+#   "contextFiles": ["(example: .opencode/context/core/story-mapping/guide.md)"],
+#   "agentOutputs": [".tmp/architecture/auth-system/contexts.json"],
+#   "metadata": {"boundedContext":"authentication"}
+# }
+```
+
+### Show Full Index
+
+```bash
+npx ts-node context-index.ts show auth-system
+# {
+#   "feature": "auth-system",
+#   "created": "2026-02-15T10:00:00Z",
+#   "agents": { ... }
+# }
+```
+
+---

+# Multi-Stage Orchestration Workflow
+
+## Quick Reference
+
+**Purpose**: End-to-end workflow for complex feature development from concept to release
+
+**8 Stages**: Architecture Decomposition → Story Mapping → Prioritization → Enhanced Task Breakdown → Contract Definition → Parallel Execution → Integration & Validation → Release & Learning
+
+**Key Agents**: OpenCoder (orchestrator), TaskManager, BatchExecutor, CoderAgent, ContextScout, ExternalScout
+
+**When to Use**: Complex features requiring multi-agent coordination, parallel execution, and systematic integration
+
+---
+
+## Overview
+
+The Multi-Stage Orchestration Workflow is a comprehensive framework for managing complex software development from initial requirements through to release. It coordinates multiple specialized agents, enables parallel execution, and ensures systematic integration and validation.
+
+### Core Philosophy
+
+- **Decompose before building**: Break down complexity systematically
+- **Plan before executing**: Define contracts and dependencies upfront
+- **Parallelize when possible**: Execute independent work simultaneously
+- **Validate continuously**: Integrate and test throughout the process
+- **Learn and improve**: Capture insights for future iterations
+
+### Workflow Stages

+  createUser(data: CreateUserData): Promise<User>;
+  getUser(id: string): Promise<User | null>;
+  updateUser(id: string, data: UpdateUserData): Promise<User>;
+  deleteUser(id: string): Promise<void>;
+}
+
+export interface CreateUserData {
+  email: string;
+  name: string;
+  role: UserRole;
+}
+
+export interface User {
+  id: string;
+  email: string;
+  name: string;
+  role: UserRole;

+## Example: Authentication System
+
+### Stage 1: Architecture Decomposition
+
+**Components Identified**:
+- User Service (user management)
+- Auth Service (authentication logic)
+- Token Service (JWT handling)
+- Middleware (request validation)
+- Database Layer (user storage)
+
+**Integration Points**:
+- Auth Service ↔ User Service (user lookup)
+- Auth Service ↔ Token Service (token generation)
+- Middleware ↔ Token Service (token validation)
+
+### Stage 2: Story Mapping
+
+**User Stories**:
+1. As a user, I want to register an account
+2. As a user, I want to log in with email/password
+3. As a user, I want to reset my password
+4. As a user, I want to stay logged in (refresh tokens)
+5. As an admin, I want to manage user roles
+
+### Stage 3: Prioritization
+
+**Phase 1** (Must-have):
+- Story 1: Registration
+- Story 2: Login
+
+**Phase 2** (Should-have):
+- Story 4: Refresh tokens
+- Story 3: Password reset
+
+**Phase 3** (Nice-to-have):
+- Story 5: Role management
+
+### Stage 4: Enhanced Task Breakdown
+
+**Batch 1** (Parallel):
+- Task 01: Setup project structure
+- Task 02: Configure database schema
+- Task 03: Install dependencies
+
+**Batch 2** (Parallel):
+- Task 04: Implement User Service
+- Task 05: Implement Token Service
+
+**Batch 3** (Sequential):
+- Task 06: Implement Auth Service (depends on 04, 05)
+
+**Batch 4** (Parallel):
+- Task 07: Create registration endpoint
+- Task 08: Create login endpoint
+
+**Batch 5** (Sequential):
+- Task 09: Integration tests (depends on all)
+
+### Stage 5: Contract Definition
+
+```typescript
+// contracts/auth-service.ts
+export interface AuthService {
+  register(data: RegisterData): Promise<AuthResult>;
+  login(credentials: LoginCredentials): Promise<AuthResult>;
+  refreshToken(token: string): Promise<AuthResult>;
+}
+
+export interface AuthResult {
+  success: boolean;
+  user?: User;
+  accessToken?: string;
+  refreshToken?: string;
+  error?: string;
+}
+```
+
+### Stage 6: Parallel Execution
+
+**Batch 1 Execution**:
+- BatchExecutor delegates tasks 01, 02, 03 to three CoderAgents
+- All execute simultaneously
+- All complete and mark status
+- BatchExecutor verifies and reports
+
+**Batch 2 Execution**:
+- BatchExecutor delegates tasks 04, 05 to two CoderAgents
+- Both execute simultaneously
+- Both complete and mark status
+- BatchExecutor verifies and reports
+
+### Stage 7: Integration & Validation
+
+- Wire Auth Service to User Service and Token Service
+- Test registration flow end-to-end
+- Test login flow end-to-end
+- Validate error handling
+- Confirm all acceptance criteria met
+
+### Stage 8: Release & Learning
+
+- Deploy to production
+- Monitor authentication metrics
+- Document JWT implementation decisions
+- Update security patterns based on learnings
+
+---
+
+## Best Practices
+
+### Planning Phase (Stages 1-4)
+
+- **Invest time upfront**: Thorough planning prevents rework
+- **Involve stakeholders**: Validate assumptions early
+- **Document decisions**: Capture rationale for future reference
+- **Identify risks early**: Address unknowns before implementation
+
+### Execution Phase (Stages 5-6)
+
+- **Define contracts first**: Prevents integration issues
+- **Maximize parallelization**: Execute independent work simultaneously
+- **Monitor progress**: Track batch completion actively
+- **Fail fast**: Detect and address issues immediately
+
+### Validation Phase (Stage 7)
+
+- **Test continuously**: Don't wait until the end
+- **Validate against requirements**: Ensure acceptance criteria met
+- **Test integration points**: Focus on component interactions
+- **Document issues**: Track and resolve systematically
+
+### Learning Phase (Stage 8)
+
+- **Capture insights immediately**: Don't wait for retrospectives
+- **Update standards**: Apply learnings to improve future work
+- **Share knowledge**: Document for team benefit
+- **Iterate**: Use insights to improve next iteration
+
+---
+
+## Common Patterns
+
+### Pattern 1: Foundation → Features → Integration
+
+1. Setup infrastructure (database, auth, logging)
+2. Build core features in parallel
+3. Integrate and validate
+
+### Pattern 2: Vertical Slices
+
+1. Implement one complete user journey
+2. Validate end-to-end
+3. Repeat for next journey
+
+### Pattern 3: Contract-First Development
+
+1. Define all interfaces upfront
+2. Implement components independently
+3. Integration is straightforward
+
+---
+
+## Troubleshooting
+
+### Issue: Tasks blocked by dependencies
+
+**Solution**: Review dependency graph, identify if dependencies can be removed or if contracts can enable parallel work
+
+### Issue: Integration failures
+
+**Solution**: Verify contracts were followed, check for interface mismatches, validate data flow
+
+### Issue: Batch execution delays
+
+**Solution**: Check for hidden dependencies, verify tasks are truly independent, consider splitting into smaller batches
+
+### Issue: Acceptance criteria unclear
+
+**Solution**: Refine criteria in planning stage, involve stakeholders, make criteria binary (pass/fail)
+
+---
+
+## Summary
+
+The Multi-Stage Orchestration Workflow provides a systematic approach to complex feature development:
+
+1. **Decompose** the system into manageable components
+2. **Map** user journeys and create stories
+3. **Prioritize** work based on value and risk
+4. **Break down** into atomic, executable tasks
+5. **Define** integration contracts upfront
+6. **Execute** independent work in parallel
+7. **Integrate** and validate continuously
+8. **Release** and capture learnings
+
+By following this workflow, teams can:
+- Reduce complexity through systematic decomposition
+- Maximize throughput via parallel execution
+- Minimize integration issues through contract-first development
+- Improve continuously through structured learning
+
+**Key Success Factors**:
+- Thorough planning before execution
+- Clear contracts and interfaces
+- Effective parallel coordination
+- Continuous validation
+- Systematic learning capture

+# Session Context Pattern
+
+## Problem
+
+**Context Fragmentation in Multi-Agent Orchestration**
+
+When orchestrating complex features across multiple agents (TaskManager → CoderAgent → TestEngineer), each agent is stateless and loses context between delegations:
+
+- **TaskManager** creates subtasks but doesn't know what ContextScout discovered
+- **CoderAgent** doesn't see what ArchitectureAnalyzer decided
+- **TestEngineer** doesn't know what files CoderAgent created
+- **Orchestrator** has to manually pass context in every delegation
+
+This leads to:
+- ❌ Repeated context discovery (inefficient)
+- ❌ Inconsistent decisions (agents don't see previous choices)
+- ❌ Lost architectural context (bounded contexts, contracts, ADRs)
+- ❌ Manual context passing (error-prone, verbose)
+
+## Solution
+
+**Persistent Session Context File**
+
+Create a single `context.md` file that all agents read and update throughout the feature lifecycle:
+
+```
+.tmp/sessions/{session-id}/context.md
+```
+
+This file acts as the **shared memory** for the entire orchestration session.
+
+## Architecture
+
+### Session Lifecycle
+
+```
+1. Orchestrator creates session → context.md initialized
+2. ContextScout updates → adds context_files
+3. ArchitectureAnalyzer updates → adds bounded_context, module
+4. TaskManager reads context → creates subtasks with full context
+5. CoderAgent reads context → knows all decisions, files, contracts
+6. TestEngineer reads context → knows what to test
+7. Orchestrator marks complete → session archived
+```
+
+### Context.md Structure
+
+```markdown
+# Task Context: {Feature Name}
+
+Session ID: {session-id}
+Created: {timestamp}

+
+## When to Use
+
+### Use Session Context When:
+
+✅ **Multi-agent orchestration** - Feature requires 3+ agents working sequentially
+✅ **Complex features** - Needs architecture analysis, contracts, ADRs
+✅ **Stateful workflows** - Later agents need to know what earlier agents did
+✅ **Context-heavy tasks** - Lots of standards, patterns, decisions to track
+
+### Don't Use Session Context When:
+
+❌ **Single agent tasks** - Simple subtask execution (CoderAgent alone)
+❌ **Stateless operations** - Each task is independent
+❌ **Quick fixes** - Bug fixes, small updates
+
+## Usage by Agent Type
+
+### Orchestrator (MetaAgent)
+
+**Stage 0: Initialize Session**
+
+```typescript
+import { createSession } from '.opencode/skill/task-management/scripts/session-context-manager';
+
+const result = createSession(feature, request, {
+  contextFiles: [], // Will be populated by ContextScout
+  referenceFiles: [],
+  exitCriteria: [
+    'All subtasks completed',
+    'Tests passing',
+    'Documentation updated'
+  ]
+});
+
+const sessionId = result.sessionId;
+// Pass sessionId to all subsequent agents
+```
+
+**Between Stages: Update Context**
+
+```typescript
+import { updateSession, markStageComplete } from './session-context-manager';
+
+// After ContextScout completes
+updateSession(sessionId, {
+  contextFiles: [
+    '.opencode/context/core/standards/code-quality.md',
+    '.opencode/context/core/standards/security-patterns.md'
+  ]
+});
+
+// After ArchitectureAnalyzer completes
+updateSession(sessionId, {
+  architecture: {
+    boundedContext: 'authentication',
+    module: '@app/auth'
+  }
+});
+
+// Mark stage complete
+markStageComplete(sessionId, 'Stage 1: Planning', [
+  '.tmp/tasks/auth-system/task.json',
+  '.tmp/tasks/auth-system/subtask_01.json'
+]);
+```
+
+**Final Stage: Complete Session**
+
+```typescript
+updateSession(sessionId, { status: 'completed' });
+```
+
+### TaskManager
+
+**Stage 0: Load Session Context**
+
+```typescript
+import { loadSession } from '.opencode/skill/task-management/scripts/session-context-manager';
+
+const result = loadSession(sessionId);
+if (!result.success) {
+  throw new Error(`Session not found: ${sessionId}`);
+}
+
+const session = result.session;
+
+// Use session context for task planning
+const contextFiles = session.contextFiles; // Standards to follow
+const referenceFiles = session.referenceFiles; // Source files to look at
+const architecture = session.architecture; // Bounded context, module
+const contracts = session.contracts; // API contracts
+const adrs = session.adrs; // Architectural decisions
+```
+
+**Stage 2: Create Tasks with Full Context**
+
+```json
+{
+  "id": "auth-system",
+  "name": "Authentication System",
+  "context_files": ["...from session.contextFiles..."],
+  "reference_files": ["...from session.referenceFiles..."],
+  "bounded_context": "...from session.architecture.boundedContext...",
+  "module": "...from session.architecture.module...",
+  "contracts": ["...from session.contracts..."],
+  "related_adrs": ["...from session.adrs..."]
+}
+```
+
+**Stage 3: Update Progress**
+
+```typescript
+import { addDecision } from './session-context-manager';
+
+addDecision(sessionId, {
+  decision: 'Split authentication into 3 subtasks: schema, service, middleware',
+  rationale: 'Each subtask is atomic (1-2 hours) and has clear dependencies'
+});
+```
+
+### CoderAgent
+
+**Before Coding: Load Session Context**
+
+```typescript
+import { loadSession } from '.opencode/skill/task-management/scripts/session-context-manager';
+
+const result = loadSession(sessionId);
+const session = result.session;
+
+// Read context files (standards)
+session.contextFiles.forEach(file => {
+  // Load coding standards, security patterns
+});
+
+// Read reference files (existing code)
+session.referenceFiles.forEach(file => {
+  // Study existing patterns
+});
+
+// Check architectural constraints
+const boundedContext = session.architecture?.boundedContext;
+const contracts = session.contracts; // API contracts to implement
+const adrs = session.adrs; // Architectural decisions to follow
+```
+
+**After Coding: Track Files Created**
+
+```typescript
+import { addFile } from './session-context-manager';
+
+addFile(sessionId, 'src/auth/jwt.service.ts');
+addFile(sessionId, 'src/auth/jwt.service.test.ts');
+```
+
+### ContextScout
+
+**After Discovery: Update Session**
+
+```typescript
+import { updateSession } from './session-context-manager';
+
+updateSession(sessionId, {
+  contextFiles: [
+    '.opencode/context/core/standards/code-quality.md',
+    '.opencode/context/core/standards/security-patterns.md',
+    '(example: .opencode/context/core/standards/naming-conventions.md)'
+  ],
+  referenceFiles: [
+    'src/middleware/auth.middleware.ts',
+    'src/config/jwt.config.ts'
+  ]
+});
+```
+
+### ArchitectureAnalyzer
+
+**After Analysis: Update Session**
+
+```typescript
+import { updateSession, addDecision } from './session-context-manager';
+
+updateSession(sessionId, {
+  architecture: {
+    boundedContext: 'authentication',
+    module: '@app/auth',
+    verticalSlice: 'user-login'
+  }
+});
+
+addDecision(sessionId, {
+  decision: 'Place authentication in separate bounded context',
+  rationale: 'Auth is a core domain with clear boundaries, used by multiple features'
+});
+```
+
+### ContractManager
+
+**After Contract Definition: Update Session**
+
+```typescript
+import { updateSession } from './session-context-manager';
+
+updateSession(sessionId, {
+  contracts: [
+    {
+      type: 'api',
+      name: 'AuthAPI',
+      path: 'src/api/auth.contract.ts',
+      status: 'defined'
+    },
+    {
+      type: 'interface',
+      name: 'JWTService',
+      path: 'src/auth/jwt.service.ts',
+      status: 'draft'
+    }
+  ]
+});
+```

+
+## Benefits
+
+✅ **No context loss** - All agents see the full picture
+✅ **Consistent decisions** - Architectural choices tracked and visible
+✅ **Efficient** - Context discovered once, used by all agents
+✅ **Auditable** - Complete history of decisions and progress
+✅ **Self-documenting** - context.md is human-readable
+✅ **Resumable** - Can pause and resume orchestration
+
+## Best Practices
+
+### 1. Initialize Early
+Create session at the start of orchestration, before any agent work begins.
+
+### 2. Update After Each Stage
+Every agent that completes work should update the session context.
+
+### 3. Read Before Acting
+Every agent should load session context before starting work.
+
+### 4. Track Decisions
+Use `addDecision()` for any architectural or design choice.
+
+### 5. Track Files
+Use `addFile()` for every file created (helps with cleanup, rollback).
+
+### 6. Use Exit Criteria
+Define clear, binary exit criteria at session creation.
+
+## Example: Full Orchestration Flow
+
+```typescript
+// Orchestrator: Initialize
+const { sessionId } = createSession('auth-system', 'Implement JWT authentication', {
+  exitCriteria: ['All tests passing', 'JWT tokens signed with RS256']
+});
+
+// Stage 0: ContextScout discovers context
+updateSession(sessionId, {
+  contextFiles: ['.opencode/context/core/standards/code-quality.md'],
+  referenceFiles: ['src/middleware/auth.middleware.ts']
+});
+markStageComplete(sessionId, 'Stage 0: Context Loading', []);
+
+// Stage 1: ArchitectureAnalyzer analyzes
+updateSession(sessionId, {
+  architecture: { boundedContext: 'authentication', module: '@app/auth' }
+});
+addDecision(sessionId, {
+  decision: 'Separate bounded context for auth',
+  rationale: 'Core domain with clear boundaries'
+});
+markStageComplete(sessionId, 'Stage 1: Architecture Analysis', []);
+
+// Stage 2: TaskManager creates tasks
+const { session } = loadSession(sessionId);
+// Use session.contextFiles, session.architecture in task.json
+markStageComplete(sessionId, 'Stage 2: Task Planning', [
+  '.tmp/tasks/auth-system/task.json'
+]);
+
+// Stage 3: CoderAgent implements
+const { session } = loadSession(sessionId);
+// Read session.contextFiles, session.contracts
+addFile(sessionId, 'src/auth/jwt.service.ts');
+markStageComplete(sessionId, 'Stage 3: Implementation', [
+  'src/auth/jwt.service.ts'
+]);
+
+// Stage 4: Complete
+updateSession(sessionId, { status: 'completed' });
+```
