name: gaia-react-perf
description: 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". Do NOT trigger on vague "feels slow", "janky", or "optimize my app" (react-doctor's `scan` mode covers those).

Run the GAIA **react-perf** measure-only diagnostic with these arguments: `$ARGUMENTS`

Run it in whichever tree holds the branch, the main checkout or a linked worktree: the dev server and Playwright bind that tree's own ports (`bash .gaia/scripts/ports.sh` prints them).

Read `frontend/.claude/skills/gaia-react-perf/references/measure-only.md` from the project root and follow it exactly. Treat the arguments above as an optional inline target (the page plus the micro-interaction to profile); if empty, ask the user to name a concrete micro-interaction before proceeding, per the reference.
