What problem does it solve?

This Skill helps you design and review HTTP systems so the method meanings, status code families, conditional request behavior, content negotiation, and caching rules match RFC 9110/9111 expectations.

Core Features & Use Cases

  • Method semantics validation: Determine safe vs. idempotent behavior and ensure the chosen method matches the operation’s semantics.
  • Status code selection guidance: Pick correct 2xx/3xx/4xx/5xx families based on outcome rather than convention.
  • Conditional requests & caching correctness: Use ETag/If-* and Cache-Control/Vary correctly to prevent retry bugs and cache poisoning.
  • Practical verification checklist: Confirms idempotency, header contracts, and correct 401 vs 403 usage.

Quick Start

Use the http-semantics skill to review whether your API’s GET/POST/PUT/PATCH/DELETE handlers, status codes, and caching headers follow RFC semantics and won’t break CDN/proxy behavior.
