claude-skills

por Jeffallan · Jeffallan/claude-skills

66 full-stack developer skills across 12 categories — auto-loads the right reference when you ask about NestJS JWT, React hooks, or Postgres indexes.

A focused skill library for full-stack developers. 66 SKILL.md bundles cover languages, backend and frontend frameworks (NestJS, React, etc.), infrastructure, APIs, testing, DevOps, security, data/ML, and platform-specific patterns. Contextual activation means mentioning a specific stack auto-pulls the relevant reference.

Implement JWT auth in NestJS the idiomatic way

👤 Backend engineers working in NestJS ⏱ ~40 min intermediate

Cuándo usarlo: You need JWT with refresh tokens and don't want to wire up the passport modules from scratch.

Requisitos previos
  • NestJS project — nest new my-app
Flujo
  1. Request the implementation
    Use the NestJS skill. Add JWT auth with refresh tokens to this project.✓ Copiado
    → Claude loads the NestJS reference and produces idiomatic module structure (AuthModule, JwtStrategy, guards)
  2. Add tests
    Now add e2e tests for the auth endpoints using the testing skill.✓ Copiado
    → Jest + supertest test files following NestJS conventions

Resultado: Production-pattern JWT auth with tests.

Errores comunes
  • Claude mixes NestJS decorators with Express middleware patterns — Insist on 'NestJS idioms only — no raw Express'
Combinar con: github

Diagnose a React perf regression

👤 Frontend engineers ⏱ ~30 min intermediate

Cuándo usarlo: A page that was snappy is now janky and React DevTools shows too many re-renders.

Flujo
  1. Share the suspect component
    Use the React skill. Here's the component tree [paste]. Identify why Settings.tsx re-renders on every keystroke.✓ Copiado
    → Concrete diagnosis (context provider wrap, unmemoized object prop, etc.) with the fix
  2. Apply + measure
    Apply the fix and walk me through how to verify in DevTools.✓ Copiado
    → Specific profiler steps

Resultado: A fixed render regression with a reproducible verification.

Errores comunes
  • Wrapping everything in memo/useCallback without measuring — The skill explicitly pushes measure-first
Combinar con: chrome-devtools
