Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Use Chrome DevTools MCP for frontend performance work such as slow page loads, LCP, CLS, INP, Lighthouse regressions, scripting hotspots, or layout thrash. Trigger when the user asks for page speed analysis, Core Web Vitals debugging, trace-based investigation, or before-and-after performance verification.

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/'chrome-performance' ] || [ -L ~/.agents/skills/'chrome-performance' ]; then echo 'A skill folder named chrome-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '40706766fd37c03ca624f5206741fef55dd2a684' -- 'plugins/win4r/chrome-devtools-codex-plugin/skills/chrome-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/win4r/chrome-devtools-codex-plugin/skills/chrome-performance' ~/.agents/skills/'chrome-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/'chrome-performance' ~/.claude/skills/'chrome-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
