Definindo Roles

Roles são personas de IA especializadas que focam em aspectos específicos do desenvolvimento. Em vez de um assistente genérico, você obtém um especialista em um domínio particular.

Por que Roles?

Sem Roles

Você: "Review this code"
IA: *Dá feedback genérico sobre tudo*

Com Roles

Você: "Review this code" (usando o role security-reviewer)
IA: *Foca em vulnerabilidades de segurança, problemas de autenticação, validação de dados*

Roles fornecem:

Foco: Expertise em áreas específicas
Consistência: Mesma perspectiva em todas as tarefas
Qualidade: Análise mais profunda no domínio do role
Segurança: Restrições embutidas previnem excessos

Criando Roles Personalizados

Quando Criar um Novo Role

Você tem tarefas recorrentes em um domínio específico
Roles genéricos não capturam a expertise necessária
Você quer comportamento consistente para trabalho especializado

Exemplo: Security Reviewer

- 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

Exemplo: Performance Optimizer

# Role: Performance Optimizer

- Code remains maintainable

Combinações de Roles

Algumas tarefas se beneficiam de múltiplos roles. Especifique primário e secundário:

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

A IA deve priorizar a perspectiva do role primário enquanto incorpora as preocupações do role secundário.

Guia de Seleção de Roles

Tipo de Tarefa	Role Primário	Role Secundário
Nova funcionalidade	developer	tester
Correção de bug	developer	-
Refatoração	architect	developer
Cobertura de testes	tester	-
Revisão de código	reviewer	-
Documentação	documenter	-
Auditoria de segurança	security-reviewer	-
Performance	performance-optimizer	developer

Dicas

Seja Específico para Sua 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

Inclua Anti-Padrões

O que NÃO fazer é tão importante quanto o que fazer:

Forneça Exemplos

Mostre como é um bom 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."
