HTTP caching header analyzer that checks Cache-Control directives, ETag/Last-Modified freshness, Vary correctness, CDN cache status (X-Cache, CF-Cache-Status, Age), and stale-while-revalidate opportunities for any URL or local dev server.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'phy-http-cache-audit' ] || [ -L ~/.agents/skills/'phy-http-cache-audit' ]; then echo 'A skill folder named phy-http-cache-audit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LeoYeAI/agent-master-skills' "$d" && git -C "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/phy-http-cache-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/phy-http-cache-audit' ~/.agents/skills/'phy-http-cache-audit' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'phy-http-cache-audit' ~/.claude/skills/'phy-http-cache-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
