+## 🔄 Como Usar
+
+### Em cada novo projeto:
+1. Copiar `libs/` → `projeto/docs/dev-standards/`
+2. Selecionar pastas relevantes ao stack
+3. Consulte antes de implementar cada camada
+
+### Quando o agente codifica:
+1. `libs/best-practices/CLEAN_CODE.md` — sempre primeiro
+2. `libs/<stack>/` — padrões específicos
+3. Aplica automaticamente — não precisa lembrar de cor
+
+### Quando atualizar:
+- Nova skill instalada → ler SKILL.md → extrair conhecimento → atualizar `libs/`
+- Após cada projeto → feedback → atualizar padrões
