Ejecutar la batería de verificaciones automatizadas de un proyecto TypeScript/Node antes de aceptar una implementación como apta para merge - `tsc --noEmit` (crítico, fail-fast), `eslint` (calidad), suite de tests (comportamiento), `build` (integración) y `sonar-scanner` (análisis estático). Usar siempre que el usuario pida "revisión de código", "code review", "valida el código", "ejecuta los checks", "revisa antes de PR/merge", o tras terminar una historia o TK que toque código TS. Devolver un informe Markdown con estado por check, errores agrupados, veredicto (apto / no apto / incompleto) y próximas acciones priorizadas. No corrige código ni modifica configuración.
Improve the quality and type-safety of TypeScript/JavaScript being written or refactored — parse-don't-validate, make-illegal-states-irrepresentable, exhaustive matching, pure-function/IO separation, and public-API hygiene. Use when asked to refactor, clean up, improve, harden, or review the design/quality of code or an API. NOT for hunting bugs (that's /code-review) and NOT for vigiles's own spec/lint rules.
Systematic JavaScript/TypeScript performance audit and optimization using V8 profiling and runtime patterns. Use when (1) Users say 'optimize performance', 'audit performance', 'this is slow', 'reduce allocations', 'improve speed', 'check performance', (2) Analyzing code for performance anti-patterns (O(n²) complexity, excessive allocations, I/O blocking, template literal waste), (3) Optimizing functions regardless of current usage context - utilities, formatters, parsers are often called in hot paths even when they appear simple, (4) Fixing V8 deoptimization (monomorphic/polymorphic issues, inline caching). Audits ALL code for anti-patterns and reports findings with expected gains. Covers loops, caching, batching, memory locality, algorithmic complexity fixes with ❌/✅ patterns.
