|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Authentication
|
||||
|
||||
All endpoints require JWT authentication via the `get_current_user` dependency:
|
||||
|
||||
```http
|
||||
Authorization: Bearer <jwt_token>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Pagination
|
||||
|
||||
Standard pagination parameters for list endpoints:
|
||||
|
||||
- `skip` (default: 0, min: 0): Number of records to skip
|
||||
- `limit` (default: 100, min: 1, max: 1000): Maximum records to return
|
||||
|
||||
**Example Response:**
|
||||
```json
|
||||
{
|
||||
"total": 150,
|
||||
"skip": 0,
|
||||
"limit": 100,
|
||||
"items": [...]
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Error Handling
|
||||
|
||||
All endpoints include comprehensive error handling:
|
||||
|
||||
- **404 Not Found**: Resource doesn't exist
|
||||
- **409 Conflict**: Unique constraint violation (e.g., duplicate project state)
|
||||
- **422 Validation Error**: Invalid request data
|
||||
- **500 Internal Server Error**: Database or server error
|
||||
|
||||
**Example Error Response:**
|
||||
```json
|
||||
{
|
||||
"detail": "ConversationContext with ID abc123 not found"
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Integration with Context Compression
|
||||
|
||||
The system integrates with `api/utils/context_compression.py` for:
|
||||
|
||||
1. **Context Recall**: `format_for_injection()` - Formats contexts for Claude prompt
|
||||
2. **Project State Compression**: `compress_project_state()` - Compresses state data
|
||||
3. **Tag Extraction**: Auto-detection of relevant tags from content
|
||||
4. **Relevance Scoring**: Dynamic scoring based on age, usage, tags, importance
|
||||
|
||||
