      corrigir: `Analise completamente todo o projeto e identifique TODOS os bugs, erros, falhas, comportamentos inesperados e possíveis problemas existentes na aplicação.

Seu objetivo é realizar uma auditoria técnica profunda no sistema inteiro, corrigindo problemas de lógica, frontend, backend, integração, renderização, estado, banco de dados, responsividade e performance.

Antes de modificar qualquer coisa:
- Analise toda a estrutura do projeto
- Analise rotas, componentes, hooks, estados globais
- Analise integrações, Supabase, APIs, banco de dados
- Analise autenticação, permissões, carregamentos

Depois de identificar todos os problemas, corrija TODOS de uma única vez.`,

      refatorar: `Realize uma refatoração profunda e completa de toda a aplicação.

Objetivos:
- Elimine código duplicado e morto
- Melhore nomenclatura de variáveis, funções e componentes
- Separe responsabilidades (SRP)
- Melhore tipagem TypeScript
- Otimize imports e dependências
- Aplique padrões modernos (hooks customizados, composição)
- Melhore legibilidade e manutenibilidade
- Adicione tratamento de erros adequado`,

      melhorar: `Melhore significativamente a interface e a experiência do usuário (UI/UX) da aplicação.

Foque em:
- Design visual moderno e profissional
- Animações e transições suaves
- Feedback visual para ações do usuário
- Consistência visual entre componentes
- Tipografia e espaçamento adequados
- Estados de loading, empty e error
- Acessibilidade (contraste, foco, ARIA)
- Micro-interações que encantam o usuário`,

      otimizar: `Otimize a performance completa da aplicação.

Analise e melhore:
- Bundle size e code splitting
- Lazy loading de componentes e imagens
- Memoização (useMemo, useCallback, React.memo)
- Re-renders desnecessários
- Queries e mutations (cache, stale time)
- Imagens (formato, tamanho, lazy loading)
- CSS (especificidade, seletores complexos)
- Core Web Vitals (LCP, FID, CLS)`,

      seguranca: `Realize uma auditoria de segurança completa da aplicação.

Verifique e corrija:
- SQL Injection e XSS
- Validação de inputs (frontend e backend)
- Row Level Security (RLS) no Supabase
- Autenticação e autorização
- Exposição de dados sensíveis
- CORS e CSP
- Rate limiting
- Sanitização de dados do usuário
- Variáveis de ambiente expostas`,

      responsivo: `Torne toda a aplicação 100% responsiva e mobile-first.

Verifique e corrija:
- Layout em todos os breakpoints (mobile, tablet, desktop)
- Navegação mobile (menu hamburguer, drawer)
- Touch targets adequados (mín. 44x44px)
- Tipografia responsiva
- Imagens e mídia responsivas
- Tabelas responsivas
- Formulários mobile-friendly
- Orientação landscape/portrait
- Testes em 320px até 1920px`,
