Diagnoses React render performance by driving a micro-interaction, capturing real renders, and surfacing memo-defeating reference instability with a recommended structural fix. Measure-only, it emits a diagnosis and does not auto-fix. Trigger on `/gaia-react-perf` or natural-language asks like "profile renders", "measure renders", "why is X re-rendering", or "diagnose render performance".

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'gaia-react-perf' ] || [ -L ~/.agents/skills/'gaia-react-perf' ]; then echo 'A skill folder named gaia-react-perf already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gaia-harness/gaia' "$d" && git -C "$d" checkout --quiet 'c4a509b34c3f25df36a616a531decdfd57baa29c' -- 'apps/web/.claude/skills/gaia-react-perf' && mkdir -p ~/.agents/skills && cp -R "$d"/'apps/web/.claude/skills/gaia-react-perf' ~/.agents/skills/'gaia-react-perf' && 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/'gaia-react-perf' ~/.claude/skills/'gaia-react-perf' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
