SKILL.md

Master error handling patterns for building resilient Node.js applications that fail gracefully and provide meaningful feedback.

| Unhandled rejection warnings | Missing .catch() | Add process handler + local catches | | Error swallowed silently | Empty catch block | Log or rethrow errors | | Stack trace missing | Error.captureStackTrace not called | Use AppError base class | | Memory leak from errors | Storing error references | Use WeakMap or clean up |
