3. Click "Generate API Token"
4. Copy the token and set it as `BEAVERHABITS_API_KEY`

## Tools

### list_habits (overview)

List all habits and show a weekly ASCII overview. This is the **default response** for any habit-related query.

**Step 1** — Get all habits:

```bash
curl -s -H "Authorization: Bearer $BEAVERHABITS_API_KEY" \
  "${SERVER_URL:-https://beaverhabits.com}/api/v1/habits"
```

**Step 2** — For each habit, get completions over the last 5 days:

```bash
curl -s -H "Authorization: Bearer $BEAVERHABITS_API_KEY" \
  "${SERVER_URL:-https://beaverhabits.com}/api/v1/habits/{habit_id}/completions?date_fmt=%25d-%25m-%25Y&date_start={start}&date_end={end}&limit=100&sort=asc"
```

Response format: `["16-02-2026", "18-02-2026"]` (array of completed date strings)

**Step 3** — Render as ASCII table:

Example output:
```
              Mon   Tue   Wed   Thu   Fri   
Exercise       ✗     ✗     ✗     ✗     ✗     
English        ✓     ✗     ✗     ✗     ✗     
paipai         ✗     ✗     ✗     ✗     ✓     
Reading        ✗     ✗     ✗     ✗     ✗     
Table Tennis   ✗     ✗     ✗     ✗     ✗     
```

Use `✓` for done, `✗` for not done. Default to 5 days ending today. Emoji are stripped from habit names for proper alignment.

### complete_habit

Mark a habit as done (or undone) for a specific date.

Parameters:
- `habit_id` (resolved): Automatically resolved by calling list_habits and matching the user's habit name. Never ask the user for this value.
- `date` (required): Date in DD-MM-YYYY format
- `done` (optional): true to complete, false to uncomplete (default: `true`)

```bash
curl -s -X POST \
  -H "Authorization: Bearer $BEAVERHABITS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"date": "20-02-2026", "done": true, "date_fmt": "%d-%m-%Y"}' \
  "${SERVER_URL:-https://beaverhabits.com}/api/v1/habits/{habit_id}/completions"
```

Response: `{"day": "20-02-2026", "done": true}`

## Usage Instructions

- When the user asks to list, show, or check habits, always respond with the ASCII overview table (not a plain list).
- After completing or uncompleting a habit, always re-render the overview table to show the updated state.
- Resolve habit names → IDs via list_habits. Never ask the user for a habit_id.
- Default to today's date for completions unless specified. Use `date_fmt=%d-%m-%Y`.
