Definir Roles

Los roles son personas de IA especializadas que se enfocan en aspectos específicos del desarrollo. En lugar de un asistente genérico, obtienes un experto en un dominio particular.

¿Por qué Roles?

Sin Roles

Tú: "Review this code"
IA: *Da feedback genérico sobre todo*

Con Roles

Tú: "Review this code" (usando el rol security-reviewer)
IA: *Se enfoca en vulnerabilidades de seguridad, problemas de auth, validación de datos*

Los roles proporcionan:

• Enfoque: Experiencia en áreas específicas
• Consistencia: La misma perspectiva en todas las tareas
• Calidad: Análisis más profundo en el dominio del rol
• Seguridad: Restricciones integradas que previenen excesos

Crear Roles Personalizados

Cuándo Crear un Nuevo Rol

• Tienes tareas recurrentes en un dominio específico
• Los roles genéricos no capturan la experiencia necesaria
• Quieres comportamiento consistente para trabajo especializado

Ejemplo: Security Reviewer

# Role: Security Reviewer

## Identity

## Expertise

- OWASP Top 10
- 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

Combinaciones de Roles

Algunas tareas se benefician de múltiples roles. Especifica primario y secundario:

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

La IA debe priorizar la perspectiva del rol primario mientras incorpora las preocupaciones del rol secundario.

Consejos

Sé Específico para Tu Stack

Genérico:

## Expertise
- Frontend development

Específico:

## Expertise
- React 18 with hooks (no class components)
- TypeScript strict mode
- CSS custom properties (no CSS-in-JS)
- Vitest + Testing Library

Incluye Anti-Patrones

Lo que NO hacer es tan importante como lo que hacer:

## Constraints

- Do NOT use `any` type
- Do NOT create components over 200 lines
- Do NOT add dependencies without approval
- Do NOT modify shared utilities without discussion

Proporciona Ejemplos

Muestra cómo se ve un buen resultado:

## 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."
