Définir les Rôles

Les rôles sont des personas IA spécialisées qui se concentrent sur des aspects spécifiques du développement. Au lieu d’un assistant générique, vous obtenez un expert dans un domaine particulier.

---

Pourquoi des Rôles ?

Sans Rôles

Vous : "Review this code"
IA : *Donne un retour générique sur tout*

Avec des Rôles

Vous : "Review this code" (en utilisant le rôle security-reviewer)
IA : *Se concentre sur les vulnérabilités de sécurité, les problèmes d'authentification, la validation des données*

Les rôles apportent :

• Focus : Expertise dans des domaines spécifiques
• Cohérence : La même perspective à travers les tâches
• Qualité : Une analyse plus approfondie dans le domaine du rôle
• Sécurité : Des contraintes intégrées empêchent les dépassements

Créer des Rôles Personnalisés

Quand Créer un Nouveau Rôle

• Vous avez des tâches récurrentes dans un domaine spécifique
• Les rôles génériques ne capturent pas l’expertise nécessaire
• Vous souhaitez un comportement cohérent pour un travail spécialisé

Exemple : Security Reviewer

# Role: Security Reviewer

## Identity

You are a security expert reviewing code for vulnerabilities.

## Expertise

- Authentication/Authorization patterns
- Input validation
- SQL injection, XSS, CSRF prevention
- Secrets management
- Dependency vulnerabilities

## Responsibilities

- Review code for security vulnerabilities
- Check authentication/authorization logic
- Verify input validation
- Identify potential data exposure
- Review dependency security

## Constraints

- Do NOT implement fixes (only identify issues)
- Do NOT review non-security aspects
- Do NOT create false positives

## Quality Criteria

- Vulnerabilities are ranked by severity
- Each issue has remediation guidance
- No false positives
- OWASP categories are referenced

Exemple : Performance Optimizer

# Role: Performance Optimizer

Combinaisons de Rôles

Certaines tâches bénéficient de plusieurs rôles. Spécifiez un rôle principal et un secondaire :

## Suggested Roles
- developer (primary)
- tester (secondary - write tests after implementation)

L’IA devrait prioriser la perspective du rôle principal tout en intégrant les préoccupations du rôle secondaire.

## Examples

### Good Review Comment

"The `handleSubmit` function doesn't validate email format before sending to API.
Consider adding validation here to provide immediate user feedback and reduce
unnecessary API calls. See `src/utils/validators.ts` for existing validation helpers."

### Bad Review Comment

"This code is wrong."
