+# Claude Code Plugin - Gap Analysis & Recommendations
+
+**Date**: 2026-02-16  
+**Status**: Production-ready with identified gaps  
+**PR**: #219
+
+---
+
+## Executive Summary
+
+The Claude Code plugin is **production-ready** but has **4 critical gaps** that affect user experience and workflow efficiency:
+
+1. ❌ **Missing Planning Command** - No easy way to plan/break down tasks
+2. ❌ **Missing Context Addition Command** - No way to add context files easily
+3. ⚠️ **Inconsistent Subagent Invocation** - Format varies across skills
+4. ⚠️ **Explorer/ContextScout Behavior** - Not fully consistent with OpenCode
+
+---
+
+## Gap 1: Missing Planning Command ❌
+
+### Current State
+
+**What exists**:
+- `/task-breakdown` skill - Invokes task-manager subagent
+- Requires user to manually invoke via skill syntax
+- Part of Stage 4 (Execute) in 6-stage workflow
+
+**Problem**:
+- Users must type: "Use the task-manager subagent to break down..."
+- No simple slash command like `/oac:plan` or `/oac:breakdown`
+- Planning is buried in execution stage, not easily accessible
+
+### Recommended Solution
+
+**Add new command**: `/oac:plan`
+
+**Purpose**: Make task planning/breakdown easily accessible
+
+**Implementation**:
+```markdown
+---
+name: oac:plan
+description: Plan and break down a complex feature into atomic subtasks
+argument-hint: [feature description]
+---
+
+# Plan Feature
+
+Break down the following feature into atomic subtasks: $ARGUMENTS
+
+## Process
+
+1. **Analyze requirements** - Understand scope and complexity
+2. **Discover context** - Find relevant standards and patterns
+3. **Create task breakdown** - Generate subtask files with dependencies
+4. **Present plan** - Show task structure and execution order
+
+## Invocation
+
+This command invokes the task-manager subagent with pre-loaded context to create:
+- `.tmp/tasks/{feature}/task.json` - Feature metadata
+- `.tmp/tasks/{feature}/subtask_NN.json` - Individual subtasks
+
+## Usage Examples
+
+```bash
+# Plan a feature
+/oac:plan user authentication system
+
+# Plan with specific context
+/oac:plan API rate limiting (security focus)
+
+# Plan with constraints
+/oac:plan payment integration (PCI compliance required)
+```
+
+## Output
+
+Task files created in `.tmp/tasks/{feature}/` with:
+- Clear dependencies
+- Parallel execution flags
+- Acceptance criteria
+- Suggested agents
+```
+
+**Benefits**:
+- ✅ Easy to discover and use
+- ✅ Separates planning from execution
+- ✅ Consistent with other `/oac:*` commands
+- ✅ Reduces cognitive load for users
+
+---
+
+## Gap 2: Missing Context Addition Command ❌
+
+### Current State
+
+**What exists**:
+- `/oac:setup` - Downloads context from GitHub
+- `/context-manager` skill - Manages context configuration
+- Manual file creation for custom context
+
+**Problem**:
+- No easy way to add custom context files
+- No command to add context from GitHub worktrees
+- Users must manually create files in `.opencode/context/`
+
+### Recommended Solution
+
+**Add new command**: `/oac:add-context`
+
+**Purpose**: Easily add context files from various sources
+
+**Implementation**:
+```markdown
+---
+name: oac:add-context
+description: Add context files from GitHub, worktrees, or local files
+argument-hint: [source] [options]
+---
+
+# Add Context
+
+Add context files to your project: $ARGUMENTS
+
+## Sources
+
+### 1. GitHub Repository
+```bash
+# Add from GitHub repo
+/oac:add-context github:owner/repo
+
+# Add specific path
+/oac:add-context github:owner/repo/path/to/context
+
+# Add specific branch/tag
+/oac:add-context github:owner/repo#branch-name
+```
+
+### 2. Git Worktree
+```bash
+# Add from worktree
+/oac:add-context worktree:/path/to/worktree
+
+# Add specific subdirectory
+/oac:add-context worktree:/path/to/worktree/context
+```
+
+### 3. Local Files
+```bash
+# Add local file
+/oac:add-context file:./path/to/context.md
+
+# Add local directory
+/oac:add-context file:./path/to/context/
+```
+
+### 4. URL
+```bash
+# Add from URL
+/oac:add-context url:https://example.com/context.md
+```
+
+## Options
+
+- `--category=<name>` - Specify context category (default: custom)
+- `--priority=<level>` - Set priority (critical, high, medium)
+- `--overwrite` - Overwrite existing files
+- `--dry-run` - Preview what would be added
+
+## Examples
+
+```bash
+# Add team standards from GitHub
+/oac:add-context github:acme-corp/standards --category=team
+
+# Add from worktree
+/oac:add-context worktree:../team-context --category=team
+
+# Add custom pattern
+/oac:add-context file:./docs/patterns/auth.md --category=custom --priority=high
+
+# Preview before adding
+/oac:add-context github:owner/repo --dry-run
+```
+
+## What It Does
+
+1. **Fetches content** from specified source
+2. **Validates format** (checks for proper markdown structure)
+3. **Copies to** `.opencode/context/{category}/`
+4. **Updates navigation** (adds to navigation.md)
+5. **Verifies** context is discoverable
+
+## Output
+
+```
+✅ Added 3 context files to .opencode/context/team/
+
+Files added:
+- .opencode/context/team/standards/code-quality.md
+- .opencode/context/team/patterns/auth.md
+- .opencode/context/team/workflows/deployment.md
+
+Updated navigation:
+- .opencode/context/team/navigation.md
+
+Verification:
+✅ All files discoverable via /context-discovery
+```
+```
+
+**Benefits**:
+- ✅ Easy context addition from multiple sources
+- ✅ Supports GitHub worktrees (key requirement)
+- ✅ Validates and organizes automatically
+- ✅ Updates navigation for discoverability
+
+---
+
+## Gap 3: Inconsistent Subagent Invocation ⚠️
+
+### Current State
+
+**Skill invocation format** (via frontmatter):
+```markdown
+---
+name: context-discovery
+context: fork
+agent: context-scout
+---
+```
+
+**Problem**: Skills pass context inconsistently to subagents
+
+### Analysis of Current Patterns
+
+#### Pattern 1: Context Discovery (GOOD)
+```markdown
+# File: skills/context-discovery/SKILL.md
+
+---
+context: fork
+agent: context-scout
+---
+
+Discover context files for: **$ARGUMENTS**
+```
+
+**What happens**:
+1. Main agent invokes skill
+2. Skill forks to context-scout subagent
+3. Subagent receives: "Discover context files for: {user request}"
+4. ✅ Clean, simple, works well
+
+#### Pattern 2: Task Breakdown (GOOD)
+```markdown
+# File: skills/task-breakdown/SKILL.md
+
+---
+context: fork
+agent: task-manager
+---
+
+Break down this feature into atomic subtasks: $ARGUMENTS
+
+## Your Task
+{detailed instructions}
+```
+
+**What happens**:
+1. Main agent invokes skill
+2. Skill forks to task-manager subagent
+3. Subagent receives full skill content as prompt
+4. ✅ Includes instructions and context
+
+#### Pattern 3: Code Execution (NEEDS IMPROVEMENT)
+```markdown
+# File: skills/code-execution/SKILL.md
+
+---
+context: fork
+agent: coder-agent
+---
+
+# Code Execution Skill
+
+Implement: $ARGUMENTS
+
+{long instructions about what to do}
+```
+
+**Problem**: 
+- Instructions are in skill file, not clear if subagent sees them
+- No explicit "Context to load first" section
+- Unclear how pre-loaded context is passed
+
+### Recommended Solution
+
+**Standardize all skill → subagent invocations**:
+
+```markdown
+---
+name: skill-name
+description: Brief description
+context: fork
+agent: subagent-name
+---
+
+# Skill Name
+
+> **Subagent**: {subagent-name}  
+> **Purpose**: {what this does}
+
+---
+
+## Task
+
+{Clear, concise task description}: $ARGUMENTS
+
+---
+
+## Context Pre-Loaded
+
+The main agent has already loaded these context files (Stage 3):
+
+- {list of context files from Stage 1 discovery}
+
+**Important**: Do NOT attempt to discover context. Use what's provided above.
+
+---
+
+## Instructions
+
+{Step-by-step instructions for subagent}
+
+1. {Step 1}
+2. {Step 2}
+3. {Step 3}
+
+---
+
+## Deliverables
+
+Return:
+- {Expected output 1}
+- {Expected output 2}
+
+---
+
+## Quality Checklist
+
+Before returning, verify:
+- [ ] {Criterion 1}
+- [ ] {Criterion 2}
+```
+
+**Benefits**:
+- ✅ Consistent format across all skills
+- ✅ Explicit context passing
+- ✅ Clear instructions for subagents
+- ✅ Quality checklist ensures completeness
+
+### Files to Update
+
+1. `skills/code-execution/SKILL.md` - Add context section
+2. `skills/test-generation/SKILL.md` - Add context section
+3. `skills/code-review/SKILL.md` - Add context section
+4. `skills/external-scout/SKILL.md` - Clarify context handling
+5. `skills/parallel-execution/SKILL.md` - Add context section
+
+---
+
+## Gap 4: Explorer/ContextScout Behavior ⚠️
+
+### Current State
+
+**ContextScout subagent**:
+- ✅ Navigation-driven discovery (reads navigation.md)
+- ✅ Read-only (Glob, Grep, Read tools only)
+- ✅ Returns ranked results (Critical → High → Medium)
+- ✅ Verifies paths exist before recommending
+
+**Comparison with OpenCode**:
+
+| Feature | OpenCode | Claude Code | Status |
+|---------|----------|-------------|--------|
+| Navigation-driven | ✅ | ✅ | ✅ Same |
+| Read-only tools | ✅ | ✅ | ✅ Same |
+| Ranked results | ✅ | ✅ | ✅ Same |
+| Global fallback | ✅ | ✅ | ✅ Same |
+| Nested calls | ✅ | ❌ | ⚠️ Different (by design) |
+| Context pre-loading | ❌ | ✅ | ⚠️ Different (required) |
+
+### Key Differences (By Design)
+
+#### 1. Nested Calls
+
+**OpenCode**:
+```
+Main Agent → TaskManager → CoderAgent → ContextScout
+```
+- Subagents can call ContextScout when needed
+- Dynamic context discovery during execution
+
+**Claude Code**:
+```
+Main Agent → ContextScout (Stage 1)
+Main Agent → Read all files (Stage 3)
+Main Agent → TaskManager/CoderAgent (Stage 4)
+```
+- Only main agent can call ContextScout
+- Context pre-loaded before execution
+- Prevents nested calls (Claude Code constraint)
+
+**Impact**: ✅ Acceptable - enforced by Claude Code architecture
+
+#### 2. Context Pre-Loading
+
+**OpenCode**:
+- Subagents discover context as needed
+- Lazy loading during execution
+
+**Claude Code**:
+- Main agent discovers all context upfront (Stage 1)
+- Main agent loads all context (Stage 3)
+- Subagents use pre-loaded context (Stage 4+)
+
+**Impact**: ✅ Acceptable - required for flat hierarchy
+
+### Recommended Improvements
+
+#### Improvement 1: Explicit Context Passing
+
+**Current**: Subagents assume context is available
+
+**Recommended**: Main agent explicitly passes context in delegation
+
+**Example**:
+```markdown
+Invoke coder-agent subagent:
+
+**Task**: Implement JWT authentication service
+
+**Context Pre-Loaded** (from Stage 3):
+- .opencode/context/core/standards/code-quality.md
+- .opencode/context/core/standards/security-patterns.md
+- .opencode/context/core/standards/typescript.md
+
+**Key Requirements** (extracted from context):
+- Use functional patterns (no classes)
+- RS256 algorithm for JWT signing
+- Token expiry: 15 minutes (access), 7 days (refresh)
+- Error handling: throw typed errors
+
+**Instructions**: Implement following loaded standards.
+```
+
+**Benefits**:
+- ✅ Subagent knows exactly what context is available
+- ✅ Key requirements extracted and highlighted
+- ✅ No ambiguity about what to follow
+
+#### Improvement 2: ContextScout Recommendations
+
+**Current**: ContextScout returns file paths only
+
+**Recommended**: ContextScout also extracts key requirements
+
+**Example**:
+```markdown
+# Context Files Found
+
+## Critical Priority
+
+**File**: `.opencode/context/core/standards/code-quality.md`
+**Contains**: Code quality standards, functional patterns, error handling
+**Why**: Defines coding patterns you must follow
+
+**Key Requirements**:
+- Functional patterns (no classes)
+- Pure functions where possible
+- Explicit error handling
+- TypeScript strict mode
+
+---
+
+**File**: `.opencode/context/core/standards/security-patterns.md`
+**Contains**: Security best practices, auth patterns
+**Why**: Critical for authentication implementation
+
+**Key Requirements**:
+- RS256 for JWT signing
+- Token rotation required
+- Secure secret storage
+- Rate limiting on auth endpoints
+```
+
+**Benefits**:
+- ✅ Main agent can extract requirements immediately
+- ✅ Reduces need to re-read files
+- ✅ Highlights critical requirements
+- ✅ Faster context application
+
+---
+
+## Recommendations Summary
+
+### High Priority (Implement Before Merge)
+
+1. **Add `/oac:plan` command** - Makes planning easily accessible
+2. **Add `/oac:add-context` command** - Enables GitHub worktree integration
+3. **Standardize skill → subagent format** - Ensures consistent context passing
+
+### Medium Priority (Post-Merge)
+
+4. **Enhance ContextScout output** - Extract key requirements from context files
+5. **Add context validation** - Verify context files are properly formatted
+6. **Add context versioning** - Track context file versions and updates
+
+### Low Priority (Future Enhancement)
+
+7. **Add context search** - Search across all context files

+
+## 🎯 Key Features
+
+### Flexible Context Discovery
+
+**Before**:
+- Hardcoded to `.opencode/context`
+- No support for other locations
+- No configuration support
+
+**After**:
+- Discovers context root dynamically
+- Checks .oac config first
+- Supports .claude/context (Claude Code default)
+- Supports context (simple root-level)
+- Supports .opencode/context (OpenCode default)
+- Respects user configuration
+
+**Example**:
+```bash
+# ContextScout automatically discovers context root
+/context-discovery authentication patterns
+
+# Output shows discovered location:
+# Context Root: .claude/context (discovered from .oac config)
+```
+
+---
+
+### Easy Planning
+
+**Before**:
+- Users had to manually invoke task-manager via skill syntax
+- Planning buried in execution stage
+- No simple command
+
+**After**:
+- Simple `/oac:plan` command
+- Separates planning from execution
+- Consistent with other commands
+- Easy to discover
+
+**Example**:
+```bash
+# Plan a feature
+/oac:plan user authentication system
+
+# Creates task files in .tmp/tasks/user-authentication/
+# - task.json (feature metadata)
+# - subtask_01.json, subtask_02.json, etc.
+```
+
+---
+
+### Context Addition from Multiple Sources
+
+**Before**:
+- Only `/oac:setup` for downloading from GitHub
+- No support for worktrees
+- No support for local files
+- Manual file creation required
+
+**After**:
+- `/oac:add-context` supports 4 sources
+- GitHub repositories (with branch/tag support)
+- Git worktrees (key requirement)
+- Local files and directories
+- URLs
+
+**Example**:
+```bash
+# Add team standards from GitHub
+/oac:add-context github:acme-corp/standards --category=team
+
+# Add from worktree (key requirement)
+/oac:add-context worktree:../team-context --category=team
+
+# Add local pattern
+/oac:add-context file:./docs/auth-pattern.md --category=custom
+```
+
+---
+
+## 🔄 Integration with OAC Workflow
+
+### Stage 1: Analyze & Discover
+
+**Enhanced**:
+- ContextScout discovers context root automatically
+- Works with any context location
+- No hardcoded paths
+
+### Stage 2: Plan & Approve
+
+**New**:
+- `/oac:plan` command for easy planning
+- Creates structured task breakdown
+- Requests approval before execution
+
+### Stage 3: LoadContext
+
+**Enhanced**:
+- Context loaded from discovered root
+- Flexible location support
+- Configuration-driven
+
+### Stage 6: Complete
+
+**New**:
+- `/oac:add-context` to add learned patterns
+- Context becomes available for future tasks
+- Navigation updated automatically

+## Core Capabilities
+
+### 1. Context Root Discovery
+
+**Purpose**: Find where context files are stored in the project
+
+**Discovery Order**:
+1. **Check .oac config** - Read `context.root` setting
+2. **Check .claude/context** - Claude Code default location
+3. **Check context** - Simple root-level directory
+4. **Check .opencode/context** - OpenCode/OAC default location
+5. **Fallback** - Use `.opencode/context` and create if needed
+
+**Process**:
+```bash
+# 1. Check for .oac config
+if [ -f .oac ]; then
+  context_root=$(jq -r '.context.root // empty' .oac)
+  if [ -n "$context_root" ] && [ -d "$context_root" ]; then
+    echo "Found context root in .oac: $context_root"
+    return
+  fi
+fi
+
+# 2. Check .claude/context
+if [ -d .claude/context ]; then
+  context_root=".claude/context"
+  echo "Found context root: .claude/context"
+  return
+fi
+
+# 3. Check context
+if [ -d context ]; then
+  context_root="context"
+  echo "Found context root: context"
+  return
+fi
+
+# 4. Check .opencode/context
+if [ -d .opencode/context ]; then
+  context_root=".opencode/context"
+  echo "Found context root: .opencode/context"
+  return
+fi
+
+# 5. Fallback - create .opencode/context
+context_root=".opencode/context"
+mkdir -p "$context_root"
+echo "Created default context root: .opencode/context"
+```
+
+**Output**: Context root path (e.g., `.opencode/context`)
+
+---
+
+### 2. Add Context from Sources
+
+**Supported Sources**:
+- **GitHub**: `github:owner/repo[/path][#ref]`
+- **Git Worktree**: `worktree:/path/to/worktree[/subdir]`
+- **Local File**: `file:./path/to/file.md`
+- **Local Directory**: `file:./path/to/dir/`
+- **URL**: `url:https://example.com/context.md`
+
+**Process**:
+
+#### GitHub Source
+```bash
+# Parse: github:owner/repo/path#branch
+source="github:acme-corp/standards/security#main"
+
+# Extract components
+owner="acme-corp"
+repo="standards"
+path="security"
+ref="main"
+
+# Download via GitHub API or git sparse-checkout
+gh repo clone "$owner/$repo" --depth 1 --branch "$ref" --single-branch
+cp -r "$repo/$path"/* "$context_root/$category/"
+rm -rf "$repo"
+```
+
+#### Git Worktree Source
+```bash
+# Parse: worktree:/path/to/worktree/subdir
+source="worktree:../team-context/standards"
+
+# Validate worktree exists
+if [ ! -d "../team-context/.git" ]; then
+  echo "Error: Not a git worktree"
+  exit 1
+fi
+
+# Copy files
+cp -r "../team-context/standards"/* "$context_root/$category/"
+```
+
+#### Local File/Directory
+```bash
+# Parse: file:./path/to/context
+source="file:./docs/patterns/auth.md"
+
+# Validate exists
+if [ ! -e "./docs/patterns/auth.md" ]; then
+  echo "Error: File not found"
+  exit 1
+fi
+
+# Copy to context
+cp "./docs/patterns/auth.md" "$context_root/$category/"
+```
+
+#### URL Source
+```bash
+# Parse: url:https://example.com/context.md
+source="url:https://example.com/standards/security.md"
+
+# Download via curl
+curl -fsSL "$url" -o "$context_root/$category/$(basename $url)"
+```
+
+**Options**:
+- `--category=<name>` - Target category (default: custom)
+- `--priority=<level>` - Priority level (critical, high, medium)
+- `--overwrite` - Overwrite existing files
+- `--dry-run` - Preview without making changes
+
+---
+
+### 3. Validate Context Files
+
+**Validation Checks**:
+
+#### Check 1: Markdown Format
+```bash
+# Verify file is valid markdown
+file_type=$(file --mime-type -b "$file")
+if [[ "$file_type" != "text/plain" && "$file_type" != "text/markdown" ]]; then
+  echo "Error: Not a markdown file"
+  exit 1
+fi
+```
+
+#### Check 2: Metadata Header (Optional but Recommended)
+```markdown
+<!-- Context: category/subcategory | Priority: critical | Version: 1.0 | Updated: 2026-02-16 -->
+```
+
+#### Check 3: Structure
+- Has title (# heading)
+- Has purpose/description section
+- Has content sections
+- No broken links (internal references)
+
+#### Check 4: Navigation Entry
+- File is referenced in navigation.md
+- Category exists in navigation
+- Priority is set correctly
+
+**Validation Output**:
+```
+✅ Markdown format valid
+✅ Metadata header present
+✅ Structure valid (title, purpose, content)
+⚠️  Navigation entry missing (will be added)
+✅ No broken links
+
+Status: Valid (with warnings)
+```
+
+---
+
+### 4. Update Navigation
+
+**Purpose**: Ensure added context is discoverable via ContextScout
+
+**Process**:
+
+#### Step 1: Find or Create Navigation File
+```bash
+# Check if navigation.md exists in category
+nav_file="$context_root/$category/navigation.md"
+
+if [ ! -f "$nav_file" ]; then
+  # Create new navigation file
+  cat > "$nav_file" <<EOF
+# $category Context
+
+## Files
+
+EOF
+fi
+```
+
+#### Step 2: Add Entry
+```bash
+# Add file entry to navigation
+cat >> "$nav_file" <<EOF
+
+### $(basename "$file" .md)
+
+**File**: $category/$(basename "$file")
+**Priority**: $priority
+**Description**: $description
+**Updated**: $(date +%Y-%m-%d)
+
+EOF
+```
+
+#### Step 3: Update Root Navigation
+```bash
+# Ensure category is listed in root navigation
+root_nav="$context_root/navigation.md"
+
+if ! grep -q "$category" "$root_nav"; then
+  cat >> "$root_nav" <<EOF
+
+## $category
+
+**Location**: $category/
+**Description**: $category_description
+**Navigation**: $category/navigation.md
+
+EOF
+fi
+```
+
+---
+

+## Error Handling
+
+### Error: Context Root Not Found
+
+**Cause**: No context directory exists and .oac config missing
+
+**Solution**:
+```
+No context root found. Creating default: .opencode/context
+
+Would you like to:
+1. Use .opencode/context (OpenCode/OAC default)
+2. Use .claude/context (Claude Code default)
+3. Use context (simple root-level)
+4. Specify custom location in .oac config
+```
+
+---
+
+### Error: Source Not Found
+
+**Cause**: GitHub repo, worktree, or file doesn't exist
+
+**Solution**:
+```
+Error: Source not found
+
+Source: github:acme-corp/standards
+Error: Repository not found or not accessible
+
+Suggestions:
+- Check repository name and owner
+- Verify you have access (private repos require authentication)
+- Try with HTTPS: https://github.com/acme-corp/standards
+```
+
+---
+
+### Error: Validation Failed
+
+**Cause**: Context file doesn't meet validation criteria
+
+**Solution**:
+```
+Error: Validation failed for security-pattern.md
+
+Issues:
+❌ Not a markdown file (detected: text/html)
+❌ Missing title (no # heading)
+⚠️  No metadata header (recommended but optional)
+
+Fix these issues before adding to context.
+```
+
+---
+
+### Error: Navigation Update Failed
+
+**Cause**: Navigation file is malformed or locked
+
+**Solution**:
+```
+Error: Failed to update navigation.md
+
+Cause: File is malformed (invalid markdown structure)
+
+Suggestions:
+1. Backup current navigation.md
+2. Regenerate navigation.md from scratch
+3. Manually fix navigation.md structure
+```
+
+---
+
+## Principles
+
+- **Flexible discovery** - Support multiple context root locations
+- **Validation first** - Never add invalid context files
+- **Safe operations** - Approval for destructive changes, backups for modifications
+- **Navigation maintenance** - Keep navigation up-to-date for discoverability
+- **Clear feedback** - Detailed summaries and error messages
+- **Source agnostic** - Support GitHub, worktrees, local files, URLs
+
+---
+
+## Integration with OAC Workflow
+
+**Stage 1: Analyze & Discover**
+- ContextManager discovers context root location
+- ContextScout uses discovered root for navigation-driven discovery
+
+**Stage 3: LoadContext**
+- Main agent loads context from discovered root
+- Context files validated and organized by ContextManager
+
+**Stage 6: Complete**
+- ContextManager can add new context learned during implementation
+- Navigation updated for future discoverability

 ## Workflow
 
+### Step 0: Discover Context Root
+
+**Before discovering context files, find where context is stored:**
+
+**Discovery Order**:
+1. **Check .oac config** - Try reading `.oac` file for `context.root` setting
+2. **Check .claude/context** - Claude Code default location
+3. **Check context** - Simple root-level directory
+4. **Check .opencode/context** - OpenCode/OAC default location
+5. **Fallback** - If none found, report error (don't assume location)
+
+**Process**:
+```
+# Try reading .oac config
+Read: .oac
+  → If exists, parse JSON and extract context.root
+  → If context.root is set and directory exists, use it
+
+# Try .claude/context
+Glob: .claude/context/navigation.md
+  → If exists, use .claude/context
+
+# Try context
+Glob: context/navigation.md
+  → If exists, use context
+
+# Try .opencode/context
+Glob: .opencode/context/navigation.md
+  → If exists, use .opencode/context
+
+# If none found
+  → Return error: "No context root found. Run /oac:setup to download context files."
+```
+
+**Output**: Context root path (e.g., `.claude/context`, `context`, or `.opencode/context`)

+
+## Context Root Discovery
+
+The command automatically discovers where to add context:
+
+**Discovery Order**:
+1. **Check .oac config** - Read `context.root` setting
+2. **Check .claude/context** - Claude Code default
+3. **Check context** - Simple root-level directory
+4. **Check .opencode/context** - OpenCode/OAC default
+5. **Create .opencode/context** - Fallback if none found
+

+{
+  "context": {
+    "root": ".claude/context"
+  }
+}
+```
+
+---
+
+## Validation
+
+All added context files are validated:
+
+### Format Validation
+- ✅ Valid markdown file
+- ✅ UTF-8 encoding
+- ✅ No binary content
+
+### Structure Validation
+- ✅ Has title (# heading)
+- ✅ Has content sections
+- ⚠️  Metadata header (optional but recommended)
+
+### Navigation Validation
+- ✅ File added to navigation.md
+- ✅ Category exists in root navigation
+- ✅ Priority set correctly
+
+**Validation Output**:
+```
+✅ Markdown format valid
+✅ Structure valid (title, content)
+⚠️  Metadata header missing (recommended but optional)
+✅ Navigation entry added
+
+Status: Valid (with warnings)
+```
+
+---
+
+## Troubleshooting
+
+### "Source not found"
+
+**Cause**: GitHub repo, worktree, or file doesn't exist
+
+**Solution**:
+```bash
+# Verify GitHub repo exists
+gh repo view acme-corp/standards
+
+# Verify worktree exists
+ls -la ../team-context/.git
+
+# Verify local file exists
+ls -la ./docs/patterns/auth-flow.md
+```
+
+---
+
+### "Validation failed"
+
+**Cause**: File is not valid markdown or has structural issues
+
+**Solution**:
+```
+Error: Validation failed for security-pattern.md
+
+Issues:
+❌ Not a markdown file (detected: text/html)
+❌ Missing title (no # heading)
+⚠️  No metadata header (recommended)
+
+Fix these issues before adding to context.
+```
+
+**Fix**: Convert to markdown, add title, then retry
+
+---
+
+### "Context root not found"
+
+**Cause**: No context directory exists and .oac config missing
+
+**Solution**:
+```bash
+# Option 1: Let command create default
+/oac:add-context github:acme-corp/standards
+# Creates .opencode/context automatically
+
+# Option 2: Create .oac config
+cat > .oac <<EOF
+{
+  "context": {
+    "root": ".claude/context"
+  }
+}
+EOF
+
+# Option 3: Create directory manually
+mkdir -p .opencode/context
+```
+
+---
+
+### "Permission denied"
+
+**Cause**: No write access to context directory
+
+**Solution**:
+```bash
+# Check permissions
+ls -la .opencode/
+
+# Fix permissions
+chmod -R u+w .opencode/context/
+```
+
+---
+
+### "Navigation update failed"
+
+**Cause**: Navigation file is malformed or locked
+
+**Solution**:
+```bash
+# Backup current navigation
+cp .opencode/context/navigation.md .opencode/context/navigation.md.backup
+
+# Let command regenerate navigation
+/oac:add-context github:acme-corp/standards --category=team
+```
+
+---
+
+## Tips
+
+### ✅ Do
+
+- **Use --dry-run first** - Preview changes before applying
+- **Organize by category** - Use appropriate categories (team, custom, external)
+- **Set priority correctly** - Critical for must-read files
+- **Verify discoverability** - Test with `/context-discovery` after adding
+- **Keep worktrees updated** - Pull latest changes before adding
+- **Use version tags** - Pin to specific versions for stability
+
+### ❌ Don't
+
+- **Don't add binary files** - Only markdown files are supported
+- **Don't skip validation** - Fix validation errors before adding
+- **Don't overwrite without backup** - Use --overwrite carefully
+- **Don't add sensitive data** - Keep API keys and secrets out of context
+- **Don't add too much** - Only add relevant, high-signal context

+
+## Integration with OAC Workflow
+
+The `/oac:plan` command fits into the **6-stage OAC workflow**:
+
+### Stage 1: Analyze & Discover
+- `/oac:plan` discovers relevant context automatically
+- Finds coding standards, security patterns, workflows
+
+### Stage 2: Plan & Approve
+- Creates detailed task breakdown
+- **Requests approval** before proceeding to implementation
+
+### Stage 3: LoadContext
+- Context files already identified in task.json
+- Main agent loads them before execution
+
+### Stage 4: Execute
+- Execute subtasks in dependency order
+- Use `/code-execution` skill for each subtask
+- Track progress through subtask status
+
+### Stage 5: Validate
+- Verify acceptance criteria for each subtask
+- Run tests after each subtask completion
+
+### Stage 6: Complete
+- Mark feature as complete
+- Update documentation
+- Archive task files (optional)
+
+---
+
+## Advanced Usage
+
+### Planning with Specific Context
+
+```bash
+# Discover context first, then plan
+/context-discovery authentication security patterns
+# Review discovered context
+/oac:plan user authentication system
+```
+
+### Planning with External Dependencies
+
+```bash
+# Plan integration with external library
+/oac:plan Stripe payment integration
+
+# The task-manager will:
+# 1. Discover internal context (security, API patterns)
+# 2. Suggest using /external-scout for Stripe docs
+# 3. Create subtasks with both internal and external context
+```
+
+### Planning with Constraints
+
+```bash
+# Specify constraints in the description
+/oac:plan user authentication (must use existing database schema)
+
+# The task-manager will:
+# 1. Include reference_files for existing schema
+# 2. Create subtasks that work within constraints
+# 3. Flag potential conflicts or risks
+```
+
+---
+
+## Task Management
+
+### Viewing Task Status
+
+```bash
+# If task-cli.ts is available
+node tasks/task-cli.ts status user-authentication
+
+# Output:
+# Feature: user-authentication
+# Status: active
+# Progress: 2/4 subtasks complete (50%)
+# 
+# Subtasks:
+# ✅ 01: JWT service (completed)
+# ✅ 02: Auth middleware (completed)
+# ⏳ 03: Login endpoint (in_progress)
+# ⏸️  04: Refresh token logic (pending)
+```
+
+### Updating Subtask Status
+
+```bash
+# Mark subtask as complete
+node tasks/task-cli.ts complete user-authentication 01
+
+# Mark subtask as in progress
+node tasks/task-cli.ts start user-authentication 03
+```
+
+### Listing All Tasks
+
+```bash
+# List all active tasks
+node tasks/task-cli.ts list
+
+# Output:
+# Active Tasks:
+# - user-authentication (2/4 complete)
+# - api-rate-limiting (0/3 complete)

+```
+## Task Plan Created
+
+**Feature**: stripe-payment-integration
+**Location**: .tmp/tasks/stripe-payment-integration/
+**Files**: task.json + 5 subtasks
+
+### Subtasks
+
+**01: Set up Stripe SDK and configuration**
+- Parallel: ✅
+- Agent: CoderAgent
+- External Context: Stripe API docs (use /external-scout)
+
+**02: Create payment intent service**

+- Agent: CoderAgent
+
+### External Dependencies
+
+⚠️  This feature requires external documentation:
+- Run: /external-scout Stripe payment intents
+- Run: /external-scout Stripe webhooks
+
+### Next Steps
+1. Fetch external docs with /external-scout
+2. Execute subtasks in dependency order
+```
+
+---
+
+## Tips
+
+### ✅ Do
+
+- **Be specific** - "user authentication with JWT" is better than "auth"
+- **Mention constraints** - Include important requirements in the description
+- **Review the plan** - Check subtasks and dependencies before executing
+- **Use parallel tasks** - Take advantage of tasks that can run simultaneously
+- **Track progress** - Update subtask status as you complete them
+
+### ❌ Don't
+
+- **Don't skip planning** - Complex features benefit from upfront planning
+- **Don't ignore dependencies** - Follow the execution order
+- **Don't modify task files manually** - Use task-cli.ts or let agents update them
+- **Don't plan trivial tasks** - Simple 1-file changes don't need planning
+
+---
+
+## Troubleshooting
+
+### "No context found for planning"
+
+**Cause**: Context files haven't been downloaded
+
+**Solution**:
+```bash
+# Download context first
+/oac:setup --core
+
+# Then plan
+/oac:plan your feature
+```
+
+---
+
+### "Task files already exist"
+
+**Cause**: A task with the same name already exists
+
+**Solution**:
+```bash
+# Option 1: Use a different name
+/oac:plan user-authentication-v2
+
+# Option 2: Delete old task files
+rm -rf .tmp/tasks/user-authentication/
+
+# Option 3: Complete the existing task first
+node tasks/task-cli.ts complete user-authentication
+```
+
+---
+
+### "Subtasks seem too large"
+
+**Cause**: Feature is very complex, subtasks are >2 hours
+
+**Solution**:
+- Break down the feature further
+- Plan in phases (plan phase 1, execute, then plan phase 2)
+- Manually split large subtasks into smaller ones
+
+---
+
+## Related Commands
+
+- `/oac:setup` - Download context files (required before planning)
+- `/oac:status` - Check OAC installation status
+- `/oac:help` - View all available commands
+
+## Related Skills
+
+- `/context-discovery` - Discover context before planning
+- `/task-breakdown` - Alternative way to invoke task-manager
+- `/code-execution` - Execute planned subtasks
+- `/test-generation` - Generate tests for subtasks
+
+---
+
+## Success Criteria
+
+After running `/oac:plan`, you should have:
+
+- ✅ Task files created in `.tmp/tasks/{feature}/`
+- ✅ Clear subtasks with binary acceptance criteria
+- ✅ Dependencies mapped correctly
+- ✅ Parallel tasks identified
+- ✅ Context files referenced
+- ✅ Execution order clear
+
