Optimize web performance: bundle size, images, caching, lazy loading, and overall page speed. Use when site is slow, reducing bundle size, fixing layout shifts, improving Time to Interactive, or optimizing for Lighthouse scores. Triggers on: web performance, bundle size, page speed, slow site, lazy loading. Do NOT use for Core Web Vitals-specific fixes (use core-web-vitals), running Lighthouse audits (use perf-lighthouse), or Astro-specific optimization (use perf-astro).

Install

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

if [ -e ~/.agents/skills/'perf-web-optimization' ] || [ -L ~/.agents/skills/'perf-web-optimization' ]; then echo 'A skill folder named perf-web-optimization already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/onfire7777/universal-ai-skills-library' "$d" && git -C "$d" checkout --quiet '2a76bf42ce5c860adf8d0f3fcf3f6804109ac65b' -- 'skills/perf-web-optimization' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/perf-web-optimization' ~/.agents/skills/'perf-web-optimization' && 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/'perf-web-optimization' ~/.claude/skills/'perf-web-optimization' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
