### 3. Start Using

Restart your AI client and start capturing moments:

```
Hey AI, mark this moment: "Successfully implemented Redis caching" as a win with tags: api, performance
```

### 4. Multi-Agent Example (v0.4.0)

```
# Register an agent
register_actor with id: "code_reviewer", type: "agent", name: "Code Reviewer"

# Create a task
create_task with title: "Review authentication module", assigned_to: "code_reviewer"

# Agent captures moments linked to the task
mark_moment with title: "Found SQL injection vulnerability", task_id: "task_xyz"

# Hand off to another agent
create_handoff_for_agent with task_id: "task_xyz", from_agent: "code_reviewer", to_agent: "security_fixer"
```

## 📊 Use Cases

### Multi-Agent Development Pipeline
```
# Code reviewer agent finds issues
register_actor id: "reviewer", type: "agent"
create_task title: "Security audit of auth module"
mark_moment title: "Found 3 SQL injection vulnerabilities"

# Hand off to security agent
create_handoff_for_agent from: "reviewer", to: "security_fixer"
→ Includes context, RETEX cards, risk warnings

# Security agent fixes and reports
update_task status: "completed", outcome: "success"
```

### Context-Aware Agent Routing
```
# Predict what context an agent needs
predict_agent_needs task_id: "xxx", actor_id: "debugger"
→ Returns recommended moments, RETEX cards, warnings

# Evaluate optimal context window
evaluate_context_window task_id: "xxx", budget_tokens: 2000
→ Returns ranked moments that fit the budget
```

### Cross-Session Continuity
```
# End of day in Claude Desktop
Generate handoff → Get compact transition card

# Next morning in Cursor IDE
Read handoff://{id} → Instantly resume with full context
```
