# Quest System

**Status:** Planned
**Phase:** 4 (AI Integration + Story Progression)
**Timeline:** Week 9 of Phase 4 (Days 13-14)
**Last Updated:** November 16, 2025

---

## Overview

The Quest System provides structured objectives and rewards for players during their solo story progression sessions. Quests are defined in YAML files and offered to players by the AI Dungeon Master based on context-aware triggers and location-based probability.

**Key Principles:**
- **YAML-driven design** - Quests defined in data files, no code changes needed
- **Context-aware offering** - AI analyzes narrative context to offer relevant quests
- **Location-based triggers** - Different areas have different quest probabilities
- **Max 2 active quests** - Prevents player overwhelm
- **Random but meaningful** - Quest offering feels natural, not forced
- **Rewarding progression** - Quests provide gold, XP, and items

---

## Quest Structure

### Quest Components

A quest consists of:

1. **Metadata** - Name, description, difficulty, quest giver
2. **Objectives** - Specific goals to complete (ordered or unordered)
3. **Rewards** - Gold, XP, items awarded upon completion
4. **Offering Triggers** - Context and location requirements
5. **Narrative Hooks** - Story fragments for AI to use in offering

---

## Data Models

### Quest Dataclass

```python
@dataclass
class Quest:
    """Represents a quest with objectives and rewards."""

    quest_id: str                           # Unique identifier (e.g., "quest_rats_tavern")

## Quest Offering Logic

### When Quests Are Offered

Quests are checked for offering after each story turn action, using a two-stage process:

#### Stage 1: Location-Based Probability Roll

```python
def roll_for_quest_offering(location_type: str) -> bool:
    """Roll to see if any quest should be offered this turn."""

    base_probabilities = {
        "town": 0.30,        # 30% chance in towns/cities
        "tavern": 0.35,      # 35% chance in taverns (special location)
        "wilderness": 0.05,  # 5% chance in wilderness
        "dungeon": 0.10,     # 10% chance in dungeons
    }

    chance = base_probabilities.get(location_type, 0.05)
    return random.random() < chance
```

#### Stage 2: Context-Aware Selection

If the roll succeeds, the AI Dungeon Master analyzes the recent narrative context to select an appropriate quest:

```python
def select_quest_from_context(
    available_quests: List[Quest],
    character: Character,
    session: GameSession,
    location: str,
    location_type: str
) -> Optional[Quest]:
    """Use AI to select a contextually appropriate quest."""

    # Filter quests by eligibility
    eligible_quests = [
        q for q in available_quests
        if q.offering_triggers.can_offer(
            character.level,
            location,
            location_type,
            character.completed_quests
        )
    ]

    if not eligible_quests:
        return None

    # Build context for AI decision
    context = {
        "character_name": character.name,
        "character_level": character.level,
        "location": location,
        "recent_actions": session.conversation_history[-3:],
        "available_quests": [
            {
                "quest_id": q.quest_id,
                "name": q.name,
                "narrative_hooks": q.narrative_hooks,
                "difficulty": q.difficulty
            }
            for q in eligible_quests
        ]
    }

    # Ask AI to select most fitting quest (or none)
    prompt = render_quest_selection_prompt(context)
    ai_response = call_ai_api(prompt)

    selected_quest_id = parse_quest_selection(ai_response)

    if selected_quest_id:
        return next(q for q in eligible_quests if q.quest_id == selected_quest_id)

    return None
```

## Quest Tracking and Completion

### Accepting a Quest

**Endpoint:** `POST /api/v1/quests/accept`

**Request:**
```json
{
  "character_id": "char_abc123",
  "quest_id": "quest_rats_tavern"
}
```

**Response:**
```json
{
  "success": true,
  "quest": {
    "quest_id": "quest_rats_tavern",
    "name": "Rat Problem",
    "description": "The local tavern is overrun with giant rats...",
    "objectives": [
      {
        "objective_id": "kill_rats",
        "description": "Kill 10 giant rats in the tavern basement",
        "current_progress": 0,
        "required_progress": 10,
        "completed": false
      }
    ],
    "status": "active"
  }
}
```

### Updating Quest Progress

Quest progress is updated automatically during combat or story actions:

```python
def update_quest_progress(character: Character, event_type: str, event_data: Dict) -> List[str]:
    """Update quest progress based on game events."""

    updated_quests = []

    for quest_id in character.active_quests:
        quest = load_quest(quest_id)

        for objective in quest.objectives:
            if objective.completed:
                continue

            # Match event to objective type
            if objective.objective_type == "kill" and event_type == "enemy_killed":
                if matches_objective(objective, event_data):
                    quest.update_progress(objective.objective_id, objective.current_progress + 1)
                    updated_quests.append(quest_id)

            elif objective.objective_type == "collect" and event_type == "item_obtained":

## Implementation Timeline

### Week 9 of Phase 4 (Days 13-14)

**Day 13: Quest Data Models & Service**
- Create Quest, QuestObjective, QuestReward, QuestTriggers dataclasses
- Create QuestService (load from YAML, manage state)
- Write 5-10 example quest YAML files (2 easy, 2 medium, 1 hard)
- Unit tests for quest loading and progression logic

**Day 14: Quest Offering & Integration**
- Implement quest offering logic (context-aware + location-based)
- Integrate quest offering into story turn flow
- Quest acceptance/completion API endpoints
- Quest progress tracking during combat/story events
- Quest UI components (tracker, offering modal, detail view)
- Integration testing

---

## Testing Criteria

### Unit Tests
- ✅ Quest loading from YAML
- ✅ Quest.is_complete() logic
- ✅ Quest.update_progress() logic
- ✅ QuestTriggers.can_offer() filtering
- ✅ QuestService.get_available_quests() filtering

### Integration Tests
- ✅ Quest offered during story turn
- ✅ Accept quest (add to active_quests)
- ✅ Quest limit enforced (max 2 active)
- ✅ Quest progress updates during combat
- ✅ Complete quest and receive rewards
- ✅ Level up from quest XP
- ✅ Abandon quest

### Manual Testing
- ✅ Full quest flow (offer → accept → progress → complete)
- ✅ Multiple quests active simultaneously
- ✅ Quest offering feels natural in narrative
- ✅ Context-aware quest selection works
- ✅ Location-based probabilities feel right

---

## Success Criteria

- ✅ Quest data models implemented and tested
- ✅ QuestService loads quests from YAML files
- ✅ Quest offering logic integrated into story turns
- ✅ Context-aware quest selection working
- ✅ Location-based probability rolls functioning
- ✅ Max 2 active quests enforced
- ✅ Quest acceptance and tracking functional
- ✅ Quest progress updates automatically
- ✅ Quest completion and rewards granted
- ✅ Quest UI components implemented
- ✅ At least 5 example quests defined in YAML

---

## Future Enhancements (Post-MVP)

### Phase 13+
- **Quest chains**: Multi-quest storylines with prerequisites
- **Repeatable quests**: Daily/weekly quests for ongoing rewards
- **Dynamic quest generation**: AI creates custom quests on-the-fly
- **Quest sharing**: Multiplayer party quests
- **Quest journal**: Full quest log with completed quest history
- **Quest dialogue trees**: Branching conversations with quest givers
- **Time-limited quests**: Quests that expire after X turns
- **Reputation system**: Quest completion affects faction standing
- **Quest difficulty scaling**: Rewards scale with character level
