      summary: Submit a turn
      description: |
        Submit player input for the current turn. The backend will:
        1. Build context from universe, campaign, and lore
        2. Call the LLM for a turn proposal
        3. Execute any dice rolls
        4. Call the LLM again with roll results
        5. Validate and apply state patches
        6. Return the DM response

        This endpoint may take 5-30 seconds depending on LLM response time.

## Developer Documentation

### Setup Guide Template
```markdown
# Development Setup

## Prerequisites
- Docker and Docker Compose
- Node.js 20+ (for frontend development)
- Python 3.12+ (for backend development)
- Git

## Quick Start

1. **Clone the repository**
   ```bash
   git clone https://github.com/org/whispyrkeep.git
   cd whispyrkeep
   ```

2. **Start the development environment**
   ```bash
   docker compose up -d
   ```

3. **Access the application**
   - Frontend: http://localhost:4200
   - Backend API: http://localhost:8000
   - API Docs: http://localhost:8000/api/docs

## Backend Development

### Setup
```bash
cd backend
python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate
pip install -r requirements.txt -r requirements-dev.txt
```

### Running locally
```bash
python manage.py migrate
python manage.py runserver
```

### Running tests
```bash
pytest
pytest --cov=apps --cov-report=html
```

## Frontend Development

### Setup
```bash
cd frontend
npm install
```

### Running locally
```bash
npm start
```

### Running tests
```bash
npm test
```

## Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `DATABASE_URL` | PostgreSQL connection string | `postgres://...` |
| `REDIS_URL` | Redis connection string | `redis://localhost:6379` |
| `SECRET_KEY` | Django secret key | (required) |
| `DEBUG` | Enable debug mode | `False` |

## Troubleshooting

### Database connection errors
Ensure PostgreSQL is running:
```bash
docker compose ps postgres
```

### Frontend can't connect to API
Check CORS settings in `backend/whispyrkeep/settings/dev.py`
```

## Code Documentation

### Python Docstring Style (Google)
```python
def resolve_ability_check(
    character: CharacterSheet,
    ability: str,
    skill: str | None = None,
    dc: int = 15,
    advantage: str = "none",
    seed: int | None = None
) -> AbilityCheckResult:
    """Resolve an ability check against a DC.

    Performs a d20 roll with appropriate modifiers based on the character's
    ability scores and proficiencies, comparing against the difficulty class.

    Args:
        character: The character making the check.
        ability: The ability score to use (str, dex, con, int, wis, cha).
        skill: Optional skill for proficiency bonus. If None, uses raw ability.
        dc: The difficulty class to beat. Defaults to 15 (medium).
        advantage: Roll state - "none", "advantage", or "disadvantage".
        seed: Optional RNG seed for deterministic testing.

    Returns:
        AbilityCheckResult containing the roll, modifiers, total, and success.

    Raises:
        ValueError: If ability is not a valid ability score name.
        ValueError: If skill is not a valid skill name.

    Example:
        >>> result = resolve_ability_check(
        ...     character=my_rogue,
        ...     ability="dex",
        ...     skill="stealth",
        ...     dc=15
        ... )
        >>> print(f"Roll: {result.roll}, Total: {result.total}, Success: {result.success}")
    """
```

### TypeScript JSDoc Style
```typescript
/**
 * Service for managing campaign operations.
 *
 * @example
 * ```typescript
 * const service = inject(CampaignService);
 * service.getCampaigns().subscribe(campaigns => {
 *   console.log(campaigns);
 * });
 * ```
 */
@Injectable({ providedIn: 'root' })
export class CampaignService {
  /**
   * Fetches all campaigns for the authenticated user.
   *
   * @returns Observable of campaign array, sorted by last updated
   * @throws HttpErrorResponse if unauthorized or network error
   */
  getCampaigns(): Observable<Campaign[]> {
    return this.http.get<Campaign[]>('/api/campaigns/');
  }

  /**
   * Submits a player action for the current turn.
   *
   * @param campaignId - UUID of the campaign
   * @param userInput - Player's action text (max 10000 chars)
   * @returns Observable of turn response with DM text and state updates
   * @throws HttpErrorResponse with code 'INVALID_CAMPAIGN' if campaign not found
   * @throws HttpErrorResponse with code 'RATE_LIMITED' if too many turns submitted
   */
  submitTurn(campaignId: string, userInput: string): Observable<TurnResponse> {
    return this.http.post<TurnResponse>(
      `/api/campaigns/${campaignId}/turn/`,
      { user_input: userInput }
    );
  }
}
```

## Prompt Documentation

### System Prompt Template
```markdown
# DM System Prompt

## Purpose
This prompt establishes the core behavior of the LLM when acting as Dungeon Master.

## Template
```
You are an expert Dungeon Master running a single-player tabletop RPG session.

## Core Rules
- Follow SRD 5.2 mechanics unless the universe specifies homebrew alternatives
- Request dice rolls for uncertain outcomes; never roll dice yourself
- Output responses in the required DM_TEXT / DM_JSON format
- Never introduce Wizards of the Coast Product Identity content

## Output Format
Your response MUST contain exactly two sections:

DM_TEXT:
[Your narrative response to the player. Include dialogue, descriptions,
and suggested options. Write engagingly but concisely.]

DM_JSON:
{
  "roll_requests": [...],  // Dice rolls needed
  "patches": [...],        // State changes
  "lore_deltas": [...]     // New lore to record
}

## Behavior Guidelines
- Be descriptive but concise
- Present 2-4 clear options when appropriate
- Always allow freeform player input
- Match the tone settings for this universe
- Respect the content rating boundaries
```

## Variables Injected
- `{universe_tone}` - Tone slider values
- `{content_rating}` - G, PG, PG13, R, NC17
- `{homebrew_rules}` - Active homebrew modifications
```
