Optimize Core Web Vitals (LCP, INP, CLS) for better page experience and search ranking. Use when asked to "improve Core Web Vitals", "fix LCP", "reduce CLS", "optimize INP", "page experience optimization", or "fix layout shifts".

Works with any agent that supports SKILL.md skills.

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/'core-web-vitals' ] || [ -L ~/.agents/skills/'core-web-vitals' ]; then echo 'A skill folder named core-web-vitals already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/open-gsd/gsd-pi' "$d" && git -C "$d" checkout --quiet 'c0bc9c4e7e0a8581aeac3af397031dc3a63d012e' -- 'src/resources/skills/core-web-vitals' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/resources/skills/core-web-vitals' ~/.agents/skills/'core-web-vitals' && 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/'core-web-vitals' ~/.claude/skills/'core-web-vitals' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
