## Identity

| Property | Value |
|----------|-------|
| **Name** | Guardian |
| **Type** | Protocol (Always Active) |
| **Phase** | All Phases |

---

## Purpose

The Guardian is the **central nervous system** of Harmony. It intercepts every user message, determines intent, checks prerequisites, and routes to the appropriate agent.

---

## Core Functions

### 1. Intent Detection

Analyzes natural language to determine user intent:

```
┌─────────────────────────────────────────────────────────────────┐
│                    INTENT DETECTION                              │
├─────────────────────────────────────────────────────────────────┤
│                                                                  │
│  INPUT: "développe le système de scoring"                       │
│                                                                  │
│  STEP 1: Language Detection                                     │
│          → French detected                                       │
│                                                                  │
│  STEP 2: Keyword Analysis                                       │
│          "développe" → IMPLEMENT                                │
│          "système" → System/Feature                             │
│          "scoring" → Context: Gaming                            │
│                                                                  │
│  STEP 3: Intent Classification                                  │
│          → Intent: IMPLEMENT                                    │
│          → Confidence: 95%                                      │
│                                                                  │
└─────────────────────────────────────────────────────────────────┘
```

### 2. Prerequisite Checking

Validates that conditions are met before allowing operations:

```yaml
prerequisites:
  IMPLEMENT:
    - story_exists: true
    - story_status: ["TODO", "IN_PROGRESS"]
    - ucv_approved: true

  FIX:
    - story_exists: true  # Or creates hotfix story

  DESIGN:
    - phase: [2, 3]
    - prd_exists: true
```

### 3. Agent Routing

Routes to the appropriate agent based on intent:

| Intent | Target Agent | Required Phase |
|--------|--------------|----------------|
| ANALYZE | Analyst | 1, 2 |
| PLAN | PM | 2 |
| DESIGN | Architect | 2, 3 |
| PLAN_STORY | SM | 3 |
| CREATE_UCV | UCV Writer | 3 |
| VALIDATE_UCV | UCV Validator | 3, 4 |
| IMPLEMENT | Developer | 4 |
| FIX | Developer | 4 |
| TEST | Tester | 4 |
| EXPLORE_QA | Exploratory QA | 4 |
| SECURITY | Security Agent | 3, 4 |
| COMPLIANCE | RGPD Agent | All |
| ACCESSIBILITY | Accessibility Agent | 3, 4 |

### 4. Context Pre-Loading (Loop-Safe)

**OBLIGATOIRE**: Après le routing, Guardian charge le contexte pertinent en mémoire de travail.

```
┌─────────────────────────────────────────────────────────────────┐
│                 CONTEXT PRE-LOADING (LOOP-SAFE)                 │
├─────────────────────────────────────────────────────────────────┤

│  STEP 1: Classification (One-Shot Haiku)                        │
│          → Classify request, detect context flags               │
│          → Result cached (no re-classification)                 │
│                                                                  │
│  STEP 2: Resolution (Config Lookup)                             │
│          → Map flags to profiles/knowledge files                │
│          → No dependency chains (flat loading)                  │
│                                                                  │
│  STEP 3: Loading (Token-Budgeted)                               │
│          → Load files up to 15K token limit                     │
│          → Priority: profiles > knowledge > patterns            │
│                                                                  │
│  STEP 4: Injection (Immutable)                                  │
│          → Write to ${HARMONY_DIR}/memory/working.json                │
│          → State locked (no re-injection)                       │
│                                                                  │
└─────────────────────────────────────────────────────────────────┘
```

**State Machine (Forward-Only):**
```
IDLE → CLASSIFYING → RESOLVING → LOADING → INJECTING → LOCKED
 │          │            │           │           │         │
 │   Haiku call    Config lookup  File read   Write JSON  Done
 │   (cached)      (no deps)      (budgeted)  (immutable)
 └──────────────────────────────────────────────────────────┘
                    NO BACKWARD TRANSITIONS
```

**Safety Guards:**
- **Token Budget**: Max 15,000 tokens pre-loaded
- **Depth Guard**: MAX_DEPTH=1 (no recursive loading)
- **State Lock**: Forward-only transitions, no re-entry
- **Cache**: Classification result immutable once set

**Context Flags Detected:**
| Flag | Triggers | Loaded Profiles |
|------|----------|-----------------|
| `has_auth` | auth, login, password | security profiles, OWASP |
| `is_game` | game, gaming, unity | gaming patterns, ECS |
| `is_web` | react, vue, frontend | frontend profiles |
| `is_api` | api, endpoint, rest | backend profiles |
| `is_mobile` | mobile, ios, android | mobile profiles |

**Usage (lib/context-preloader.sh):**
```bash
source "$HARMONY_DIR/lib/context-preloader.sh"

# Pre-load context for request
preload_context "implement authentication system" "developer"

# Check state
get_preloader_state    # → LOCKED
get_preloader_tokens   # → 12500

# Display summary
display_context_summary
```

### 5. Agent Announcement (P-010)

## Enforcement Modes

### WARN Mode (Default)

```
🛡️ GUARDIAN CHECKPOINT - WARNING
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚠️ No active story detected

RECOMMENDATION:
Create a story before implementing:
  "create story for [your feature]"

Continuing anyway (WARN mode)...
```

### BLOCK Mode

```
🛡️ GUARDIAN CHECKPOINT - VIOLATION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🚫 BLOCKED: Code modification without active story

REQUIRED ACTIONS:
1. Create or activate a story first
2. Ensure UCV is approved
3. Try again

To override (not recommended):
  Set guardian.mode = "warn" in workflow-state.json
```

---

## Configuration

```json
{
  "guardian": {
    "enabled": true,
    "mode": "warn",
    "require_story": true,
    "require_ucv": true,
    "allowed_directories": [
      ".harmony/",
      ".claude/",
      "*.md"
    ],
    "blocked_directories": [
      "src/",
      "app/",
      "backend/",
      "frontend/"
    ]
  }
}
```

---

## Hook Integration

The Guardian can be enforced via hooks:

```bash
#!/bin/bash
# .harmony/hooks/guardian-checkpoint.sh

WORKFLOW_STATE=".claude/memory/workflow-state.json"

# Read current state
GUARDIAN_ENABLED=$(jq -r '.guardian.enabled // true' "$WORKFLOW_STATE")
GUARDIAN_MODE=$(jq -r '.guardian.mode // "warn"' "$WORKFLOW_STATE")
CURRENT_STORY=$(jq -r '.active_context.current_story // null' "$WORKFLOW_STATE")

# Check if story required
if [[ "$GUARDIAN_ENABLED" == "true" && "$CURRENT_STORY" == "null" ]]; then
    if [[ "$GUARDIAN_MODE" == "block" ]]; then
        echo "BLOCKED: No active story"
        exit 1
    else
        echo "WARNING: No active story"
    fi
fi
```

---

## Composite Intent Detection (OBLIGATOIRE)

Quand l'utilisateur demande plusieurs actions combinées, Guardian DOIT demander clarification.

### Patterns de Détection

```yaml
composite_triggers:
  fr:
    - "analyser et implémenter"
    - "analyser et développer"
    - "designer et coder"
    - "créer et implémenter"
    - "planifier et développer"
  en:
    - "analyze and implement"
    - "design and code"
    - "plan and develop"
    - "create and implement"
```

### Routing selon Choix

| Choix | Action | Workflow |
|-------|--------|----------|
| **1** (Complet) | Démarrer avec Analyst, enchainer tout le workflow | Analyst → SM → UCV → Dev → Test → QA |
| **2** (Quick) | Activer Quick-Flow agent | Analyst → Quick-Flow-Solo |

### Intents Composés Supportés

| Requête | Workflow Complet | Quick-Flow |
|---------|------------------|------------|
| "analyser et implémenter" | Analyst → SM → ... → Dev | Analyst → Quick-Flow |
| "designer et créer stories" | Architect → SM | Architect → Quick-Flow |
| "tester et valider" | Tester → Exploratory QA → UCV Validator | Tester → UCV Validator |
| "créer PRD et implémenter" | PM → Analyst → SM → ... → Dev | PM → Quick-Flow |

## Best Practices

1. **Don't bypass the Guardian** - It exists to protect your workflow
2. **Use natural language** - The Guardian understands context
3. **Set appropriate mode** - Use BLOCK for strict enforcement
4. **Configure directories** - Protect source code, allow docs
5. **Respect composite detection** - Toujours demander clarification sur intents multiples
