# AGENTS.md - LinkSyncServer
## Project Overview
LinkSyncServer is a self-hosted bookmark server with advanced collection and query capabilities. It provides a RESTful API and web interface for managing bookmarks (links), collections (static or dynamic sets), and supports synchronization with browser extensions.
## Setup & Build Commands
- **Build**: `docker-compose up -d --build`
- **Test**: `pytest tests/ -v`
- **Lint**: `ruff check .` && `mypy app.py models/`
- **Dev**: `docker-compose up web`
- **Migrate**: `alembic upgrade head`
## Architecture Notes
### Core Components
1. **Authentication Layer**: JWT-based auth with admin/regular user roles
2. **Link Management**: CRUD for links with all Firefox bookmark fields
3. **Collection Engine**: Static and dynamic collections with query support
4. **Query Parser**: Expression parser supporting AND/OR/XOR set operations
5. **Sync Protocol**: Extension sync endpoint with conflict resolution
### Data Models
- **User**: Authentication and authorization
- **Link**: Bookmark with all Firefox fields
- **Collection**: Static or dynamic set of links
- **Tag**: Optional categorization
- **AuditLog**: Track changes
### Query Engine
Query syntax: `('term1', 'term2') OR tagA AND tagB XOR url:example.com`
- Precedence: `()` > XOR > AND > OR
- Left-to-right evaluation otherwise
- Full-text search via PostgreSQL tsvector
## Testing Protocol
- All tests must pass before committing
- Run `pytest tests/ -v` for full test suite
- Coverage target: >80%
- E2E tests cover critical user flows
## Conventions
### File Naming
- Models: `{entity}.py` in `models/` directory
- Endpoints: `endpoints/{resource}.py`
- Queries: `queries/{operation}.py`
### Error Handling
- Use HTTP status codes appropriately
- Return structured error responses
- Log errors with stack traces in debug mode
### API Design
- RESTful conventions
- JSON responses with Content-Type
- Paginated lists with limit/offset
- OpenAPI documentation via `@openapi`
### Database
- UUID primary keys
- Timestamps on all records
- Foreign keys with cascade delete where appropriate
- Full-text search indexes on searchable fields
## Known Issues / Technical Debt
- None at initialization
- Query engine performance to be optimized
- Caching layer to be implemented
## Project-Specific Tools
- **Query Parser**: `queries/parser.py`
- **Query Executor**: `queries/executor.py`
- **Sync Logic**: `api/endpoints/sync.py`

- `tasks.md` - Implementation checklist
- `docker-compose.yml` - Deployment configuration
## Admin User Creation
Admin user is created from environment variables:
- `ADMIN_USERNAME`
- `ADMIN_PASSWORD`
- `SECRET_KEY` (generate securely)
Admin can create:
- Regular users
- Admin users
- API keys
- System settings
## Security Notes
- Never commit `.env` files
- Use strong passwords
- Rotate SECRET_KEY periodically
- Enable HTTPS in production
