## How It Works

### Automatic Context Recall

```
User writes message
    ↓
[user-prompt-submit hook executes]
    ↓
Detect project ID from git
    ↓
Query: GET /api/conversation-contexts/recall
    ↓
Retrieve relevant contexts (score ≥ 5.0, limit 10)
    ↓
Format as markdown
    ↓
Inject into conversation
    ↓
Claude processes message WITH full context
```

### Automatic Context Saving

```
Task completes in Claude Code
    ↓
[task-complete hook executes]
    ↓
Gather task info (git branch, commit, files)
    ↓
Create context summary
    ↓
POST /api/conversation-contexts
    ↓
POST /api/project-states
    ↓
Context saved for future recall
```

## Configuration

### Default Settings (Recommended)

```bash
CLAUDE_API_URL=http://localhost:8000
CONTEXT_RECALL_ENABLED=true
MIN_RELEVANCE_SCORE=5.0
MAX_CONTEXTS=10
```

### Customization Examples

**For focused work:**
```bash
MIN_RELEVANCE_SCORE=7.0   # Only high-quality contexts
MAX_CONTEXTS=5            # Keep it minimal
```

**For comprehensive context:**
```bash
MIN_RELEVANCE_SCORE=3.0   # Include more history
MAX_CONTEXTS=20           # Broader view
```

**For debugging:**
```bash
DEBUG_CONTEXT_RECALL=true # Verbose output
MIN_RELEVANCE_SCORE=0.0   # All contexts
```

## Example Output

When context is available, Claude sees:

```markdown
## 📚 Previous Context

The following context has been automatically recalled from previous sessions:

### 1. Database Schema Updates (Score: 8.5/10)
*Type: technical_decision*

Updated the Project model to include new fields for MSP integration.
Added support for contact information, billing details, and license
management. Used JSONB columns for flexible metadata storage.

Modified files: api/models.py,migrations/versions/001_add_msp_fields.py
Branch: feature/msp-integration
Timestamp: 2025-01-15T14:30:00Z

---

### 2. API Endpoint Implementation (Score: 7.8/10)
*Type: session_summary*

Created REST endpoints for MSP functionality including:
- GET /api/msp/clients - List MSP clients
- POST /api/msp/clients - Create new client
- PUT /api/msp/clients/{id} - Update client

Implemented pagination, filtering, and search capabilities.
Added comprehensive error handling and validation.

---

*This context was automatically injected to help maintain continuity across sessions.*
```

**User sees:** Context appears automatically (transparent)

**Claude gets:** Full awareness of previous work

**Result:** Seamless conversation continuity
