AC React
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.
As a process C 64/100 · Has gaps — weak spots: inputs and preconditions, running it twice, progress reporting
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- warning
name-formatname should be kebab-case (lowercase letters, digits, hyphens) - note
frontmatter-keyunknown frontmatter key "slug" - note
frontmatter-keyunknown frontmatter key "homepage" - note
frontmatter-keyunknown frontmatter key "changelog"
Process rating: all ten parameters 64/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 8 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 60Tools and files. Uses tools (web, node) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70Execution cost. Instruction body is 4085 tokens
- 100Steps. 44 steps
- 100Failures and branches. 2 branches, has a failure section
- 100Consistency. Name and required fields are in place
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 15 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
Quality signals
