| Endpoint | Method | Description |
|----------|--------|-------------|
| `/health` | GET | Health check |
| `/api/v1/skills` | GET | List skills |
| `/api/v1/skills` | POST | Create skill |
| `/api/v1/skills/:id` | GET | Get skill details |

## Number-Based Reference System

The bot uses a number-based reference system for ease of use:
1. User runs `!skills` to get a list of skills
2. Bot stores the list internally for the user
3. User can reference skills by their list number
4. Numbers are valid until the user runs a new list command

This allows simple commands like:
- `!skill 3` - Show details for skill #3
- `!xp 1 100 Training` - Add 100 XP to skill #1
- `!aktivitaeten 2` - Show activities for skill #2
