VERIFIED· install onlyPublisher claims: "Builds, debugs, and reviews React apps: components, hooks, state, Server Components, forms, performance, testing. Use when writing or refactoring components, choosing state management (useState, Context, Zustand, TanStack Query, Redux), when a component rerenders too often, loops infinitely ("too many re-renders"), shows stale or not-updating state, fails with a hydration mismatch or hook-order error, when an effect fires twice or fetches race, when typing lags or long lists scroll slowly, when adopting React 19, Server Actions, or the React Compiler, when testing components with Testing Library, typing props in TypeScript, or reviewing AI-generated React code. Not for React Native (mobile) or Next.js routing and deployment — use react-native or nextjs." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-10 and scored it 89/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Fill once; sessions read this instead of re-asking. Deviations from the recommended stack (setup.md) get a one-line reason in Notes.Fix: Keep SKILL.md to visible, descriptive text. Remove comments and encoded text that address the agent.- **React Compiler:** on / off <!-- decides Core Rule 6: hand memoization or none -->Fix: Remove the text that addresses the agent rather than the reader; describe behavior, do not instruct.- **`ref` is a normal prop** — forwardRef is no longer needed. **`<Context>`** renders as a provider directly. Migration of legacy patterns: `migration.md`.Fix: Remove the text that addresses the agent rather than the reader; describe behavior, do not instruct.Cost to the agent
Tokens estimated at four characters each. Skills load their instruction text when triggered; the figure is what that costs.
