web-performance

77 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Audit and optimize web performance — Core Web Vitals (LCP, INP, CLS), bundle splitting, lazy loading, image optimization, caching strategies, and resource hints. Use when asked to "improve performance", "fix LCP/CLS/INP", "optimize bundle", "reduce load time", "lazy load images", "add caching", or before marking any public-facing page as production-ready. Do NOT use for server-side database performance — this covers frontend and network-layer only.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'web-performance' ] || [ -L ~/.agents/skills/'web-performance' ]; then echo 'A skill folder named web-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yanacuti1121/Yana-AI' "$d" && git -C "$d" checkout --quiet '54d4aa9fa3241319f4d37212bd23826658bf6bed' -- '.claude/skills/web-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/web-performance' ~/.agents/skills/'web-performance' && 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/'web-performance' ~/.claude/skills/'web-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
