## What is OpenAgent?
OpenAgent is your **universal coordinator** that:
- ✅ **Answers questions** - Get explanations, comparisons, and guidance
- ✅ **Executes general tasks** - Create files, documentation, simple updates
- ✅ **Coordinates workflows** - Handles most general tasks directly, delegates to specialists when needed
- ✅ **Preserves context** - Remembers information across multiple steps
- ✅ **Keeps you in control** - Always asks for approval before taking action
Think of OpenAgent as a **smart project coordinator** who:
- Understands what you need
- Plans how to do it
- Asks for your approval
- Executes the plan (directly or via delegation)
- Confirms everything is done right
**Note:** For complex multi-file coding work, architecture analysis, or deep refactoring, use **opencoder** instead. OpenAgent is optimized for general tasks and coordination, while opencoder specializes in development work.

## How It Works
### The Simple Version
```mermaid
graph LR
A[You Ask] --> B{Question or Task?}
B -->|Question| C[Get Answer]
B -->|Task| D[See Plan]
D --> E[Approve Plan]
E --> F[Watch Execution]
F --> G[Confirm Done]
style A fill:#4A90E2,stroke:#2E5C8A,stroke-width:3px,color:#000
style B fill:#F5A623,stroke:#C17D11,stroke-width:3px,color:#000
style C fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
style D fill:#50E3C2,stroke:#3AB89E,stroke-width:3px,color:#000
style E fill:#F5A623,stroke:#C17D11,stroke-width:3px,color:#000
style F fill:#6B7C93,stroke:#4A5568,stroke-width:3px,color:#fff
style G fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
```
**For Questions**: You ask → You get an answer
**For Tasks**: You ask → See plan → Approve → Watch it happen → Confirm done
### Universal Coordinator Philosophy
OpenAgent is a **universal coordinator** - it handles general tasks directly:
**Capabilities**: Answer questions, create documentation, simple code updates, workflow coordination, task planning, general research, file operations
**Default**: Execute directly for general tasks, fetch context files as needed (lazy), keep it simple, don't over-delegate
**Delegate to opencoder when**: Complex multi-file coding, architecture analysis, deep refactoring, pattern implementation
**Delegate to specialists when**: Testing needed (@tester), review needed (@reviewer), complex task breakdown (@task-manager), comprehensive documentation (@documentation)
This means OpenAgent is your go-to coordinator for general tasks and questions. For deep coding work, use **opencoder**.
---
## The Two Paths
OpenAgent has two different ways of working, depending on what you need:
### Path 1: Conversational (For Questions)
```mermaid
graph TD
A[Ask Question] --> B[OpenAgent Analyzes]
B --> C[Provides Answer]
C --> D[Done!]
style A fill:#4A90E2,stroke:#2E5C8A,stroke-width:3px,color:#000
style B fill:#6B7C93,stroke:#4A5568,stroke-width:3px,color:#fff
style C fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
style D fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
```
**When**: You ask informational questions
**Examples**:
- "What's the difference between REST and GraphQL?"
- "How do I use async/await in JavaScript?"
- "Explain what this code does"
**What Happens**: You get a direct, helpful answer. No approval needed.
---
### Path 2: Task Execution (For Actions)
```mermaid
graph TD
A[Request Task] --> B[OpenAgent Creates Plan]
B --> C[Shows You Plan]
C --> D{Approve?}
D -->|Yes| E[Executes Plan]
D -->|No| F[Revise or Cancel]

G --> H[Shows Summary]
H --> I{Satisfied?}
I -->|Yes| J[Cleanup if Needed]
I -->|No| K[Fix Issues]
J --> L[Done!]
style A fill:#4A90E2,stroke:#2E5C8A,stroke-width:3px,color:#000

style L fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
```
**When**: You want something done
**Examples**:
- "Create a README for this project"
- "Build a user authentication system"
- "Refactor this code to use TypeScript"
**What Happens**:
1. You see a plan
2. You approve it
3. OpenAgent executes it
4. You confirm it's done right
---
## The 6-Stage Workflow
When you request a task, OpenAgent follows a systematic 6-stage workflow:
```mermaid
graph TD
subgraph Stage1["Stage 1: Analyze"]
A1[Receive Request] --> A2[Assess Complexity]
A2 --> A3{Question or Task?}
end
subgraph Stage2["Stage 2: Approve"]
B1[Create Plan] --> B2[Present to User]
B2 --> B3[Wait for Approval]
end
subgraph Stage3["Stage 3: Execute"]
C1[Execute Steps] --> C2{Need Help?}
C2 -->|Yes| C3[Delegate to Specialist]
C2 -->|No| C4[Do It Directly]
C3 --> C5[Integrate Results]
C4 --> C5
end
subgraph Stage4["Stage 4: Validate"]

D3 -->|Yes| D4[Report & Propose Fixes]
D4 --> D5[Wait for Approval]
D5 --> D6[Apply Approved Fixes]
D6 --> D2
D3 -->|No| D7[Ask: Review Work?]
end
subgraph Stage5["Stage 5: Summarize"]
E1[Create Summary] --> E2[Show Changes]
E2 --> E3[Suggest Next Steps]
end
subgraph Stage6["Stage 6: Confirm Completion"]
F1[Ask if Satisfied] --> F2{Session Files?}
F2 -->|Yes| F3[Ask about Cleanup]
F2 -->|No| F4[Done]
F3 --> F5[Cleanup on Approval]

### Stage 1: Analyze
```mermaid
graph TD
A[Receive User Request] --> B[Read & Parse Request]
B --> C{Assess Type}
C -->|Informational| D[Question Path]
C -->|Action Required| E[Task Path]
D --> D1[Prepare Direct Answer]
D1 --> D2[No Approval Needed]
D2 --> D3[Respond Immediately]
E --> E1[Assess Complexity]
E1 --> E2[Identify Required Resources]
E2 --> E3[Proceed to Stage 2]
style A fill:#4A90E2,stroke:#2E5C8A,stroke-width:3px,color:#fff
style C fill:#F5A623,stroke:#C17D11,stroke-width:3px,color:#000
style D fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000

style E3 fill:#6B7C93,stroke:#4A5568,stroke-width:3px,color:#fff
```
**What happens**: OpenAgent reads your request and decides if it's a question or a task.
**Your experience**: Instant - you don't see this happening.

### Stage 2: Approve ⚠️ (MANDATORY - CRITICAL RULE)
```mermaid
graph TD

style J fill:#D0021B,stroke:#A00116,stroke-width:3px,color:#fff
```
**What happens**: OpenAgent creates a plan and shows it to you.
**Critical Rule**: OpenAgent **ALWAYS** requests approval before **ANY** execution (bash, write, edit, task delegation). This is absolute and strictly enforced. Read and list operations do not require approval.
**Your experience**: You see something like:
```
## Proposed Plan
1. Create README.md file
2. Add project overview section
3. Add installation instructions
4. Add usage examples
**Approval needed before proceeding.**
```
**What you do**: Review the plan and say "yes" or "no" (or ask for changes).

style P fill:#6B7C93,stroke:#4A5568,stroke-width:3px,color:#fff
```
**What happens**: OpenAgent carries out the plan, either directly or by delegating to specialist agents.
**Your experience**: You might see:
- Files being created or modified
- Commands being run
- Progress updates
- Results from specialist agents
**Behind the scenes**: OpenAgent might create temporary files to preserve context between steps.

### Stage 4: Validate ⚠️ (MANDATORY - CRITICAL RULE)
```mermaid
graph TD

style T fill:#5A6C7D,stroke:#3D4E5C,stroke-width:3px,color:#fff
```
**What happens**: OpenAgent checks the quality of the work, runs tests if applicable, and ensures everything works correctly.
**Critical Rules Enforced**:
1. **STOP on failure** - Immediately stops execution when tests fail or errors occur
2. **REPORT first** - Always reports issues before proposing fixes
3. **NEVER auto-fix** - Always requests approval before fixing issues
**Your experience when validation passes**: You see:
```
✅ Validation complete - all checks passed.
Would you like me to run any additional checks or review the work before I summarize?
- Run specific tests
- Check specific files
- Review changes
- Proceed to summary
```
**What you do**: Choose to review further or proceed to summary.
#### Special Case: Test Failures or Issues Found
If OpenAgent runs tests or validation and finds issues, it follows a **strict protocol** (Critical Rule):
**What happens**:
1. ⛔ **STOPS** execution immediately (no auto-fix)
2. 📋 **REPORTS** all issues/failures clearly
3. 📝 **PROPOSES** a fix plan with specific steps
4. ⚠️ **REQUESTS APPROVAL** before fixing (absolute requirement)
5. ✅ **PROCEEDS** only after you approve
6. 🔄 **RE-VALIDATES** after fixes are applied
**Your experience**: You see something like:
```
## Validation Results
❌ 3 tests failed:
- test_user_auth: Expected 200, got 401
- test_login: Missing token in response
- test_logout: Session not cleared
## Proposed Fix Plan
1. Update auth middleware to return proper status codes
2. Add token generation to login endpoint
3. Add session cleanup to logout handler
**Approval needed before proceeding with fixes.**
```
**Critical**: OpenAgent will **NEVER** auto-fix issues without your explicit approval. This is an absolute rule with strict enforcement. After fixes are applied, validation runs again to ensure everything passes.

style F fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
```
**What happens**: After validation passes and you're satisfied, OpenAgent creates a summary of what was accomplished.
**Your experience**: You see a summary like:
```
## Summary
Created README.md with project documentation.
**Changes Made:**
- Created README.md
- Added project overview
- Added installation guide
- Added usage examples
**Next Steps:** Review the README and update as needed.
```

### Stage 6: Confirm Completion ⚠️ (MANDATORY - CRITICAL RULE)
```mermaid

style P fill:#7ED321,stroke:#5FA319,stroke-width:3px,color:#000
```
**What happens**: OpenAgent asks if you're satisfied and if temporary files should be cleaned up.
**Critical Rule**: OpenAgent **ALWAYS** confirms before deleting session files or cleanup operations. This is absolute and strictly enforced.
**Your experience**: You see:
```
Is this complete and satisfactory?
Should I clean up temporary session files at .tmp/sessions/20250118-143022-a4f2/?
```
**What you do**: Confirm you're happy with the results and approve cleanup if needed.
---
## Session Management
When OpenAgent works on complex tasks, it creates a **session** to keep track of everything.
### What is a Session?
A session is like a **temporary workspace** where OpenAgent stores:
- Context files (requirements, specifications)
- Task breakdowns
- Notes for specialist agents
- Progress tracking
### Session Structure
```mermaid
graph TD
A[Session Folder] --> B[manifest file]
A --> C[features folder]
A --> D[tasks folder]
A --> E[code folder]
A --> F[documentation folder]
A --> G[Other categories]
B --> B1[Tracks all files]
B --> B2[Keywords for search]
B --> B3[Creation timestamps]
C --> C1[Requirements and specs]
D --> D1[Task breakdowns]
E --> E1[Implementation notes]
F --> F1[Documentation context]
style A fill:#4A90E2,stroke:#2E5C8A,stroke-width:3px,color:#fff
style B fill:#F5A623,stroke:#C17D11,stroke-width:3px,color:#000
style C fill:#50E3C2,stroke:#3AB89E,stroke-width:2px,color:#000
style D fill:#50E3C2,stroke:#3AB89E,stroke-width:2px,color:#000
style E fill:#50E3C2,stroke:#3AB89E,stroke-width:2px,color:#000
style F fill:#50E3C2,stroke:#3AB89E,stroke-width:2px,color:#000
style G fill:#50E3C2,stroke:#3AB89E,stroke-width:2px,color:#000
```
### Session Lifecycle
```mermaid
sequenceDiagram
participant User
participant OpenAgent
participant Session
User->>OpenAgent: Request complex task
OpenAgent->>OpenAgent: Needs context file?
OpenAgent->>Session: Create session (lazy)
Session-->>OpenAgent: Session ID: abc123
OpenAgent->>Session: Create context files
OpenAgent->>OpenAgent: Execute task
OpenAgent->>User: Show results
User->>OpenAgent: Confirm done
OpenAgent->>User: Cleanup session files?
User->>OpenAgent: Yes
OpenAgent->>Session: Delete session
Session-->>OpenAgent: Cleaned up
OpenAgent->>User: All done!
```
### Key Features
**Lazy Initialization**: Sessions are only created when actually needed (not for simple tasks). OpenAgent follows a "lazy" philosophy - only creates sessions/files when truly necessary.
**Unique IDs**: Each session gets a unique ID like `20250118-143022-a4f2` to prevent conflicts.
**Safe Cleanup**: OpenAgent only deletes files it created, and only after you approve (Critical Rule).
**Concurrent Safety**: Multiple users can work simultaneously without interfering with each other.
---
## Dynamic Context Loading
One of OpenAgent's superpowers is **remembering context** across multiple steps.
### The Problem It Solves
Imagine this scenario:
1. You ask: "Build a user authentication system"
2. OpenAgent creates requirements and task breakdown
3. Later, you ask: "Implement the login component"
**Without context loading**: OpenAgent wouldn't remember the requirements from step 1.
**With context loading**: OpenAgent finds and uses the requirements automatically.
### How It Works
```mermaid
graph TD
subgraph Step1["Step 1: Create Context"]
A1[User requests auth system] --> A2[Create requirements file]
A2 --> A3[Add to manifest with keywords]
A3 --> A4[Keywords added]
end
subgraph Step2["Step 2: Create Tasks"]
B1[Delegate to task-manager] --> B2[Create task breakdown]
B2 --> B3[Add to manifest with keywords]
B3 --> B4[Keywords added]
end
subgraph Step3["Step 3: Use Context"]
C1[User requests login] --> C2[Search manifest]
C2 --> C3[Find related files]
C3 --> C4[Pass paths to specialist]
C4 --> C5[Specialist reads context]
end
Step1 --> Step2
Step2 --> Step3
style Step1 fill:#4A90E2,stroke:#2E5C8A,stroke-width:4px,color:#fff
style Step2 fill:#50E3C2,stroke:#3AB89E,stroke-width:4px,color:#000
style Step3 fill:#7ED321,stroke:#5FA319,stroke-width:4px,color:#000
```
### The Manifest
The manifest is like an **index** that tracks all context files:
```json
{
"session_id": "20250118-143022-a4f2",
"context_files": {
"features/user-auth-context.md": {
"created": "2025-01-18T14:30:22Z",
"for": "@task-manager",
"keywords": ["user-auth", "authentication", "features"]
},
"tasks/user-auth-tasks.md": {
"created": "2025-01-18T14:32:15Z",
"for": "@task-manager",
"keywords": ["user-auth", "tasks", "breakdown"]
}
},
"context_index": {
"user-auth": [
"features/user-auth-context.md",
"tasks/user-auth-tasks.md"
]
}
}
```
**Benefits**:
- ✅ No context loss across steps
- ✅ Automatic discovery by keywords
- ✅ Flexible - only loads what's needed
- ✅ Traceable - you can see what context was used
---
## When OpenAgent Delegates
OpenAgent is a **universal agent** that handles most tasks directly. It only delegates when truly needed.
### Execution Philosophy
**OpenAgent's Capabilities**: Write code, docs, tests, reviews, analysis, debugging, research, bash operations, file operations
**Default Approach**: Execute directly, fetch context files as needed (lazy loading), keep it simple
**Delegate Only When**:
- 4+ files to modify/create
- Specialized expertise needed (security, algorithms, architecture, performance)
- Thorough multi-component review required
- Complex dependencies and coordination
- Need fresh perspective or alternative approaches
- Testing scenarios, edge cases, what-if analysis
- User explicitly requests breakdown/delegation
### Decision Tree

## Tips for Your Workflow
### 1. Be Specific in Your Requests
**Instead of**: "Make this better"
**Try**: "Refactor this function to use async/await and add error handling"
**Why**: Specific requests help OpenAgent create better plans and get approval faster.
---
### 2. Review Plans Carefully
When OpenAgent shows you a plan, take a moment to review it:
- ✅ Does it match what you want?
- ✅ Are there any steps you'd change?
- ✅ Is anything missing?
**Tip**: You can ask OpenAgent to revise the plan before approving.
---
### 3. Use Multi-Step Workflows
For complex projects, break them into steps:
```
Step 1: "Build user authentication system"
→ Review task breakdown
Step 2: "Implement the registration component"
→ OpenAgent uses context from Step 1
Step 3: "Implement the login component"
→ OpenAgent uses context from Steps 1 & 2
```
**Why**: OpenAgent preserves context across steps, making each step easier.
---
### 4. Leverage Specialist Agents
Let OpenAgent delegate to specialists:
- **Complex features** → Let task-manager break them down
- **Documentation** → Let documentation agent create comprehensive docs
- **Code review** → Let reviewer agent check for issues
**Tip**: You can explicitly request a specialist: "Use the documentation agent to create API docs"
---
### 5. Clean Up Sessions Regularly
After completing a workflow, approve session cleanup:
- ✅ Keeps your workspace clean
- ✅ Prevents accumulation of temporary files
- ✅ Frees up disk space
**Tip**: You can also manually clean up stale sessions:
```bash
./scripts/maintenance/cleanup-stale-sessions.sh
```
---
### 6. Use Keywords Consistently
When working on related tasks, use consistent terminology:
- "user authentication" (not "auth" in one request and "login system" in another)
- "payment processing" (not "payments" and "checkout" interchangeably)
**Why**: Helps OpenAgent find related context files more easily.
---
### 7. Provide Context for Follow-Up Requests
When making follow-up requests, reference previous work:
**Good**: "Implement the login component from the auth system we planned earlier"
**Better**: "Implement the login component using the user-auth requirements"
**Why**: Helps OpenAgent search for the right context files.
---
### 8. Customize Delegation Thresholds
You can adjust when OpenAgent delegates by modifying the criteria in `.opencode/agent/core/openagent.md`:
**Current defaults**:
- 4+ files → Delegate to task-manager
- Specialized expertise needed → Delegate to appropriate specialist
- 1-3 files → Execute directly
**To customize**: Edit the `` section to match your preferences.
---
### 9. Create Your Own Categories
The default categories are:
- features, documentation, code, refactoring, testing, tasks, general
**To add custom categories**: Edit the `` line in openagent.md:
```xml
features | documentation | code | refactoring | testing | general | tasks | your-category
```
**Use case**: If you frequently work on "migrations" or "integrations", add those as categories.
---
### 10. Monitor Session Files
Occasionally check `.tmp/sessions/` to see what context is being preserved:
```bash
ls -la .tmp/sessions/
```
**Why**: Helps you understand what context OpenAgent is using and identify any issues.
---
### 11. Use Explicit Approvals for Learning
When learning a new codebase or technology, use OpenAgent's approval step as a learning opportunity:
- Read the plan carefully
- Ask questions about steps you don't understand
- Request explanations before approving
**Example**:
```
OpenAgent: "I'll refactor this to use dependency injection"
You: "What is dependency injection and why is it better here?"
OpenAgent: [Explains]
You: "Got it, approved!"
```
---
### 12. Combine with Other Agents
OpenAgent works great with other agents in your profile:
- Use OpenAgent for planning and coordination
- Let specialists handle their domains
- OpenAgent will preserve context between them
**Example workflow**:
1. OpenAgent plans the feature
2. @coder-agent implements it
3. @tester writes tests
4. @reviewer checks quality
5. @documentation documents it
All coordinated by OpenAgent with preserved context!
---
## Advanced Tips
### Create Reusable Context Templates
For recurring workflows, create context templates:
**Example**: `.opencode/templates/feature-context.md`
```markdown
# Feature: {FEATURE_NAME}
## Requirements
- [List requirements]
## Constraints
- [List constraints]
## Success Criteria
- [List criteria]
```
**Use**: "Create a new feature using the feature-context template"
---
### Use Session IDs for Debugging
If something goes wrong, note the session ID:
```
Session: 20250118-143022-a4f2
```
You can inspect the session folder to see what context was created:
```bash
cat .tmp/sessions/20250118-143022-a4f2/.manifest.json
```
---
### Batch Related Tasks
Group related tasks in one session for better context:
**Instead of**:
- Request 1: "Create user model"
- Request 2: "Create auth controller"
- Request 3: "Create login route"
**Try**:
- Request: "Build user authentication with model, controller, and routes"
**Why**: Single session, all context preserved, more efficient.
---
## Core Principles
OpenAgent follows these core principles:
### 🎯 Lean
Concise responses, no over-explanation. Gets to the point quickly.
### 🔄 Adaptive
Conversational for questions, formal for tasks. Matches the context.
### ⚡ Lazy
Only creates sessions/files when actually needed. No unnecessary overhead. Fetches context files on-demand.
### 🔒 Safe (CRITICAL RULE - Absolute & Strict)
**ALWAYS** requests approval before ANY execution (bash, write, edit, task delegation). Confirms before cleanup. This is an absolute rule with strict enforcement.
### 📋 Report First (CRITICAL RULE - Absolute & Strict)
When tests fail or issues are found:
1. **STOP** immediately (no auto-fix)
2. **REPORT** the issues clearly
3. **PROPOSE** fix plan
4. **REQUEST APPROVAL** (mandatory)
5. **FIX** (only after approval)
**Never auto-fixes** - you're always in control. This is an absolute rule with strict enforcement.
### 🛡️ Critical Rules Summary
Three critical rules are enforced with absolute priority:
1. **Approval Gate** - Always request approval before execution
2. **Stop on Failure** - Stop immediately on test failures or errors, never auto-fix
3. **Confirm Cleanup** - Always confirm before deleting session files
---
## Summary
OpenAgent is your **intelligent universal agent** that:
✅ **Plans before acting** - Shows you the plan and waits for approval (Critical Rule)
✅ **Preserves context** - Remembers information across multiple steps
✅ **Executes directly** - Handles most tasks itself, delegates only when needed
✅ **Keeps you in control** - Always confirms before cleanup (Critical Rule)
✅ **Handles general tasks** - Questions, docs, coordination, simple updates (delegates complex coding to opencoder)
✅ **Reports before fixing** - Never auto-fixes issues without approval (Critical Rule)
**Key Takeaways**:
1. Be specific in your requests
2. Review plans before approving
3. Use multi-step workflows for complex projects
4. OpenAgent handles most tasks directly - delegation is the exception, not the rule
5. Clean up sessions when done
6. Customize to fit your workflow
7. Expect reports before fixes when issues are found (never auto-fix)
**Ready to get started?** Just ask OpenAgent a question or request a task!

## Configuration
OpenAgent is configured in `.opencode/agent/core/openagent.md`. You can customize:
- Delegation thresholds (when to delegate vs execute directly)
- Execution philosophy (universal agent approach)
- Critical rules enforcement
- Workflow stages
- Context loading behavior
- And more!
### Architecture & Design (Nov 2025)
OpenAgent has been optimized based on research-backed prompt engineering patterns:
✅ **Critical rules positioned early** - Safety rules appear in the first 15% of the prompt with absolute priority
✅ **Minimal nesting complexity** - Flattened XML structure (max 2 levels) for maximum clarity
✅ **Modular design** - Context files loaded on-demand (lazy loading)
✅ **Explicit prioritization** - 3-tier priority system with conflict resolution
✅ **Single source of truth** - Critical rules defined once and referenced throughout
✅ **Universal agent philosophy** - Execute directly first, delegate only when truly needed
**Key Principles**:
- **Tier 1 (Highest)**: Safety & Approval Gates - Always override other tiers
- **Tier 2**: Core Workflow - Stage progression and delegation routing
- **Tier 3**: Optimization - Lazy initialization, session management, context discovery
**Effectiveness improvements are model- and task-specific.** These patterns are validated by Stanford/Anthropic research but actual performance gains vary based on your specific use case.
### Static Context Files
OpenAgent uses context files from `.opencode/context/core/` on-demand (lazy loading):
**Standards** (quality guidelines):
- `standards/code.md` - Modular, functional code patterns
- `standards/docs.md` - Documentation standards
- `standards/tests.md` - Testing standards
- `standards/patterns.md` - Core patterns
- `standards/analysis.md` - Analysis framework
**Workflows** (process templates):
- `workflows/delegation.md` - Delegation template and process
- `workflows/task-breakdown.md` - Task breakdown methodology
- `workflows/sessions.md` - Session lifecycle management
- `workflows/review.md` - Code review guidelines
These files are fetched only when needed, keeping the system lean and efficient. OpenAgent references them without the `@` symbol (e.g., `standards/code.md` not `@standards/code.md`).
Happy building! 🚀
