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

Measure, diagnose, and remediate Core Web Vitals and asset budget violations using structured profiling, causality analysis, and repeatable remediation patterns. Triggers on "diagnose why this route fails LCP", "find the cause of our INP regression", "bring this page back under its asset budget".

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/'fe-performance' ] || [ -L ~/.agents/skills/'fe-performance' ]; then echo 'A skill folder named fe-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/eugenelim/agent-ready-repo' "$d" && git -C "$d" checkout --quiet 'b148cf91e083e5a25d673c95234a940c4578503e' -- 'packs/frontend-engineering/.apm/skills/fe-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/frontend-engineering/.apm/skills/fe-performance' ~/.agents/skills/'fe-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/'fe-performance' ~/.claude/skills/'fe-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
