## Agents

### Core Agents

| Agent | Model | Role |
|-------|-------|------|
| `@Explore` | - | Analyse codebase initiale |

| `@planner` | sonnet | Plan en phase Convergent |
| `@security-auditor` | opus | Audit securite conditionnel |
| `@ems-evaluator` | haiku | Calcul EMS 5 axes + weak_axes |
| `@technique-advisor` | haiku | Auto-selection techniques (63 en CSV) |

### v5.0 Agents

| Agent | Model | Role |
|-------|-------|------|
| `@party-orchestrator` | sonnet | Orchestration multi-persona (5 personas) |
| `@expert-panel` | sonnet | Panel 5 experts dev (3 phases) |

## EMS Calculation (via @ems-evaluator)

**MANDATORY: Invoke @ems-evaluator at each iteration.**

Axes (weights):
- Clarte (25%) — Precision du besoin
- Profondeur (20%) — Niveau de detail
- Couverture (20%) — Exhaustivite
- Decisions (20%) — Choix actes
- Actionnabilite (15%) — Pret pour action

**Invocation:**
```
Task tool -> @ems-evaluator (haiku)
Input: current brief state, previous EMS, open questions
Output: 5-axis scores, composite, delta, weak_axes, recommendations
```

**Output includes (v4.8+):**
- `weak_axes[]` — Liste des axes avec score < 50
- Trigger auto-technique si `weak_axes` non vide

**Thresholds:**

| EMS Range | Recommendation | Technique Trigger | Checkpoint |
|-----------|----------------|-------------------|------------|
| 0-49 | CONTINUE | Si axe < 50 → SUGGEST_TECHNIQUE | - |
| 50-69 | SUGGEST_CONVERGE | Si axe < 50 → SUGGEST_TECHNIQUE | Transition (EMS=50) |
| 70-84 | FINALIZATION_CHECKPOINT | Non (proche finish) | **Finalization** |
| 85-100 | FINALIZATION_CHECKPOINT | Non | **Finalization** |

**IMPORTANT**: À EMS >= 85, NE JAMAIS finaliser automatiquement.
Toujours afficher le Finalization Checkpoint et attendre le choix explicite.

## Technique Selection (via @technique-advisor)

### Technique Library (v5.0)

**MANDATORY: Load techniques from CSV, not deprecated .md files.**

```
Read src/skills/core/brainstormer/references/techniques.csv
Read src/skills/core/brainstormer/references/technique-mapping.md
```

**10 Categories (63 Techniques):**

| Category | Count | Primary Phase |
|----------|-------|---------------|
| collaborative | 5 | Divergent |
| creative | 11 | Divergent |
| deep | 8 | Convergent |
| introspective | 6 | Divergent |
| structured | 9 | Convergent |
| theatrical | 6 | Divergent |
| wild | 8 | Divergent |
| biomimetic | 3 | Divergent |
| quantum | 3 | Convergent |
| cultural | 4 | Divergent |

### Auto-Invocation

**Declenchement automatique** a chaque iteration si:
1. Au moins un axe EMS < 50 (retourne par `@ems-evaluator` dans `weak_axes`)
2. Technique correspondante pas utilisee dans les 2 dernieres iterations
3. Pas en mode `--no-technique`

**Invocation manuelle:**
- `technique [name]` — Applique technique specifique
- `--random` flag — Selection aleatoire avec equilibrage categories
- `--progressive` flag — Selection basee sur phase EMS

### Mapping EMS → Categories

| Axe Faible | Categories Primaires | Categories Secondaires |
|------------|---------------------|------------------------|
| Clarte < 50 | deep, structured | creative |
| Profondeur < 50 | deep, introspective | creative, theatrical |
| Couverture < 50 | creative, collaborative, wild | theatrical, biomimetic |
| Decisions < 50 | structured, deep | collaborative |
| Actionnabilite < 50 | structured | collaborative, wild |

### Mix de Techniques

Quand 2+ axes sont faibles:
- Combiner 1 technique par axe faible (max 2)
- Privilegier techniques complementaires (Divergent + Convergent)
- Eviter 2 techniques de meme categorie
- Ordre: Divergent d'abord, puis Convergent

### Format Proposition

**Technique unique:**
```
💡 Technique suggérée: [NOM] ([CATEGORIE])
   Raison: Axe [X] à [Y]% — [effet attendu]

→ Appliquer? [Y/n/autre]
```

**Mix (2+ axes faibles):**
```
💡 TECHNIQUES SUGGÉRÉES | Iteration [N]

Axes faibles: [Axis1] ([X]%), [Axis2] ([Y]%)

[1] [Technique1] → [Axis1]
[2] [Technique2] → [Axis2]

→ [1] / [2] / [b]oth / [n]one
```

### Session Tracking

Ajouter dans session YAML (`techniques_history`):
```yaml
techniques_history:
  - iteration: 3
    suggested: ["six-hats", "moscow"]
    applied: ["six-hats"]
    reason: "Couverture 35%, Decisions 42%"
```

### Invocation Agent

```
Task tool -> @technique-advisor (haiku)
Input: phase, weak_axes, techniques_used
Output: selected technique(s), adapted questions
```

## Question Format

3-5 questions par iteration avec choix A/B/C:

```
1. [Question 1]
   A) Option A  B) Option B  C) Option C
   -> Suggestion: B

2. [Question 2]
   A) Option A  B) Option B  C) Option C
```

## Breakpoint Format

```
-------------------------------------------------------
[PHASE] | [PERSONA] | Iter X | EMS: XX/100 (+Y)
-------------------------------------------------------
Done: [elements valides]
Open: [points a clarifier]

Questions:
1. [Question] -> Suggestion: [si applicable]
2. [Question]
3. [Question]

-> continue | dive [topic] | back | save | energy | finish
-------------------------------------------------------
```

## Finalization Checkpoint

**Trigger:** EMS >= 85 (première fois atteint dans la session)

**Format obligatoire:**
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
FINALIZATION CHECKPOINT | EMS: XX/100
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Le brief est suffisamment mature pour être finalisé.

[1] Continuer (plus d'itérations)
[2] Preview plan (@planner) sans finaliser
[3] Finaliser maintenant (finish)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

**Comportement selon choix:**
- [1] Continuer → génère 3-5 questions, poursuit itérations normalement
- [2] Preview → invoque @planner, affiche plan, PUIS redemande [1]/[3]
- [3] Finaliser → passe en Phase 3 Generation

**CRITICAL:** Ce checkpoint est BLOQUANT. Ne pas continuer sans réponse explicite.

## @planner Integration

**Invocation:** Uniquement sur choix explicite [2] au Finalization Checkpoint
ou commande `plan-preview`

**Confirmation préalable:** `Lancer @planner? [Y/n]`

Invoke via Task tool (model: sonnet).
Output integre dans brief section "Preliminary Plan".

## @security-auditor Integration

**Auto-detection:** Patterns auth/security/payment/api

**Confirmation:** `Lancer @security-auditor? [Y/n]`

Invoke via Task tool (model: opus).
Output integre dans brief section "Security Considerations".

## Phase 3 — Generation

**MANDATORY: Use Write tool for BOTH files using official templates.**

**CRITICAL: Before generating, ALWAYS read the template:**
```
Read src/skills/core/brainstormer/references/brief-format.md
```

1. Create directory: `mkdir -p ./docs/briefs/[slug]`
2. **Read template** `references/brief-format.md` (MANDATORY)
3. Section-by-section validation (si pas --quick/--turbo)
4. Write `brief-[slug]-[date].md` — **Must include**:
   - Personas section (min 1 primary persona)
   - User Stories format (En tant que... je veux... afin de)
   - Acceptance Criteria (Given/When/Then)
   - Success Metrics (KPIs or "TBD")
5. Write `journal-[slug]-[date].md` — Using Journal template
6. Display completion summary

**Anti-pattern**: Generating brief without reading template first = INVALID

**Completion format:**
```
-------------------------------------------------------
BRAINSTORM COMPLETE
-------------------------------------------------------
EMS Final: XX/100
Agents: [@planner | @security-auditor | Aucun]

Fichiers generes:
   - Brief: ./docs/briefs/[slug]/brief-[slug]-[date].md
   - Journal: ./docs/briefs/[slug]/journal-[slug]-[date].md

Prochaine etape: Lancer /brief avec le contenu du brief.
-------------------------------------------------------
```

## Framework Detection

| Signal | Framework |
|--------|-----------|
| Priorisation | MoSCoW |
| "Pourquoi" repete | 5 Whys |
| Plusieurs options | SWOT |
| Criteres multiples | Scoring |
| Risques | Pre-mortem |

## Anti-patterns

**Ne pas faire:**
- Plus de 5 questions par iteration
- Breakpoint > 15 lignes
- Ignorer contexte codebase
- `finish` avant EMS 60
- Finaliser automatiquement à EMS >= 85 (CRITIQUE)
- Invoquer @planner sans choix explicite utilisateur
- Generer brief SANS lire `references/brief-format.md` d'abord (CRITIQUE)
- Omettre section Personas dans le brief
- Utiliser format SF au lieu de User Stories
- Omettre Acceptance Criteria Given/When/Then

**Toujours faire:**
- Invoquer @ems-evaluator a chaque iteration
- Proposer suggestions avec questions
- Respecter format compact CLI
- Afficher Finalization Checkpoint à EMS >= 85
- Attendre réponse explicite [1]/[2]/[3] avant action
- Lire `brief-format.md` AVANT de generer le brief
- Inclure Personas, User Stories, Success Metrics dans le brief
