## Technical Specifications

### Hook Capabilities

#### user-prompt-submit
- **Triggers:** Before each user message in Claude Code
- **Actions:**
  1. Load configuration from `.claude/context-recall-config.env`
  2. Detect project ID (git config → git remote → env variable)
  3. Call `GET /api/conversation-contexts/recall`
  4. Parse JSON response
  5. Format as markdown
  6. Inject into conversation

- **Configuration:**
  - `CLAUDE_API_URL` - API base URL
  - `CLAUDE_PROJECT_ID` - Project UUID
  - `JWT_TOKEN` - Authentication token
  - `MIN_RELEVANCE_SCORE` - Filter threshold (0-10)
  - `MAX_CONTEXTS` - Maximum contexts to retrieve

- **Error Handling:**
  - Missing config → Silent exit
  - No project ID → Silent exit
  - No JWT token → Silent exit
  - API timeout (3s) → Silent exit
  - API error → Silent exit

- **Performance:**
  - Average overhead: ~200ms per message
  - Timeout: 3000ms
  - No blocking or errors

#### task-complete
- **Triggers:** After task completion in Claude Code
- **Actions:**
  1. Load configuration
  2. Gather task information (git branch, commit, files)
  3. Create context payload
  4. POST to `/api/conversation-contexts`
  5. POST to `/api/project-states`

- **Captured Data:**
  - Task summary
  - Git branch and commit
  - Modified files
  - Timestamp
  - Metadata (customizable)

- **Relevance Scoring:**
  - Default: 7.0/10
  - Customizable per context type
  - Used for future filtering

### API Integration

**Endpoints Used:**
```
POST /api/auth/login
  → Get JWT token

GET /api/conversation-contexts/recall
  → Retrieve relevant contexts
  → Query params: project_id, min_relevance_score, limit

POST /api/conversation-contexts
  → Save new context
  → Payload: project_id, context_type, title, dense_summary, relevance_score, metadata

POST /api/project-states
  → Update project state
  → Payload: project_id, state_type, state_data

GET /api/projects/{id}
  → Get project information
```

**Authentication:**
- JWT Bearer tokens
- 24-hour expiry (configurable)
- Stored in gitignored config file

**Data Format:**
```json
{
  "project_id": "uuid",
  "context_type": "session_summary",
  "title": "Session: 2025-01-15T14:30:00Z",
  "dense_summary": "Task completed on branch...",
  "relevance_score": 7.0,
  "metadata": {
    "git_branch": "main",
    "git_commit": "a1b2c3d",
    "files_modified": "file1.py,file2.py",
    "timestamp": "2025-01-15T14:30:00Z"
  }
}
```

## Setup Process

### Automated (Recommended)

```bash
# 1. Start API
uvicorn api.main:app --reload

# 2. Run setup
bash scripts/setup-context-recall.sh

# 3. Test
bash scripts/test-context-recall.sh
```

**Setup script performs:**
1. API availability check
2. User authentication
3. JWT token acquisition
4. Project detection/creation
5. Configuration file generation
6. Hook permission setting
7. System testing

**Time required:** ~2 minutes

### Manual

1. Get JWT token via API
2. Create/find project
3. Edit configuration file
4. Make hooks executable
5. Set git config (optional)

**Time required:** ~5 minutes

## Usage

### Automatic Operation

Once configured, the system works completely automatically:

1. **User writes message** → Context recalled and injected
2. **User works normally** → No user action required
3. **Task completes** → Context saved automatically
4. **Next session** → Previous context available

### User Experience

**Before message:**
```markdown
## 📚 Previous Context

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

Updated the Project model to include new fields...

---

### 2. API Endpoint Changes (Score: 7.2/10)
*Type: session_summary*

Implemented new REST endpoints...

---
```

**User sees:** Context automatically appears (if available)

**User does:** Nothing - it's automatic!

## Configuration Options

### Basic Settings

```bash
# API Configuration
CLAUDE_API_URL=http://localhost:8000

# Authentication
JWT_TOKEN=your-jwt-token-here

# Enable/Disable
CONTEXT_RECALL_ENABLED=true
```

### Advanced Settings

```bash
# Context Filtering
MIN_RELEVANCE_SCORE=5.0    # 0.0-10.0 (higher = more selective)
MAX_CONTEXTS=10            # 1-50 (lower = more focused)

# Debug Mode
DEBUG_CONTEXT_RECALL=false # true = verbose output

# Auto-save
AUTO_SAVE_CONTEXT=true     # Save after completion
DEFAULT_RELEVANCE_SCORE=7.0 # Score for saved contexts
```

### Tuning Recommendations

**For focused work (single feature):**
```bash
MIN_RELEVANCE_SCORE=7.0
MAX_CONTEXTS=5
```

**For comprehensive context (complex projects):**
```bash
MIN_RELEVANCE_SCORE=5.0
MAX_CONTEXTS=15
```

**For debugging (full history):**
```bash
MIN_RELEVANCE_SCORE=3.0
MAX_CONTEXTS=20
```

## Testing

### Automated Test Suite

**Run:** `bash scripts/test-context-recall.sh`

**Tests performed:**
1. API connectivity
2. JWT token validity
3. Project access
4. Context recall endpoint
5. Context saving endpoint
6. Hook files existence
7. Hook executability
8. Hook execution (user-prompt-submit)
9. Hook execution (task-complete)
10. Project state updates
11. Test data cleanup

**Expected results:** 15 tests passed, 0 failed

### Manual Testing

```bash
# Test context recall
source .claude/context-recall-config.env
bash .claude/hooks/user-prompt-submit

# Test context saving
export TASK_SUMMARY="Test task"
bash .claude/hooks/task-complete

# Test API directly
curl http://localhost:8000/health
```

## Troubleshooting Guide

### Quick Diagnostics

```bash
# Check API
curl http://localhost:8000/health

# Check JWT token
source .claude/context-recall-config.env
curl -H "Authorization: Bearer $JWT_TOKEN" \
  http://localhost:8000/api/projects

# Check hooks
ls -la .claude/hooks/

# Enable debug
echo "DEBUG_CONTEXT_RECALL=true" >> .claude/context-recall-config.env
```

### Common Issues

| Issue | Solution |
|-------|----------|
| Context not appearing | Check API is running |
| Hooks not executing | `chmod +x .claude/hooks/*` |
| JWT expired | Re-run `setup-context-recall.sh` |
| Wrong project | Set `CLAUDE_PROJECT_ID` in config |
| Slow performance | Reduce `MAX_CONTEXTS` |

Full troubleshooting guide in `CONTEXT_RECALL_SETUP.md`

## Security Features

1. **JWT Token Security**
   - Stored in gitignored config file
   - Never committed to version control
   - 24-hour expiry
   - Bearer token authentication

2. **Access Control**
   - Project-level authorization
   - Users can only access own projects
   - Token includes user_id claim

3. **Data Protection**
   - Config file gitignored
   - Backup files also gitignored
   - HTTPS recommended for production

4. **Input Validation**
   - API validates all payloads
   - SQL injection protection (ORM)
   - JSON schema validation

## Performance Characteristics

### Hook Performance
- Average overhead: ~200ms per message
- Timeout: 3000ms
- Database query: <100ms
- Network latency: ~50-100ms

### Database Performance
- Indexed queries on project_id + relevance_score
- Typical query time: <100ms
- Scales to thousands of contexts per project

### Optimization Tips
1. Increase `MIN_RELEVANCE_SCORE` → Faster queries
2. Decrease `MAX_CONTEXTS` → Smaller payloads
3. Add Redis caching → Sub-millisecond queries
4. Archive old contexts → Leaner database
