This skill exists so those adjacent concerns stay out of scope and the review stays focused on structural defects that erode testability and maintainability.</p>\n<h2>When to use</h2>\n<p>Use this skill when the user asks to:</p>\n<ul>\n<li>review a React component or feature PR for architecture before merge,</li>\n<li>answer \"is this component doing too much\",</li>\n<li>audit prop-drilling or context usage across a component subtree,</li>\n<li>assess whether new or existing components should be split, merged, or recomposed.</li>\n</ul>\n<p>Do not use this skill for:</p>\n<ul>\n<li>pure styling/CSS review — no architecture concern is in scope,</li>\n<li>performance profiling that requires live browser traces — that needs a runtime tool, not static review,</li>\n<li>state-management library selection with no existing code to review — that is a design conversation, not a review.</li>\n</ul>\n<h2>Context7 Documentation Protocol</h2>\n<ul>\n<li>Resolve the React library ID with <code>resolve-library-id</code> (matched result: <code>/reactjs/react.dev</code>) before citing any React-specific claim.</li>\n<li>Before asserting a component-splitting or state-placement recommendation is \"React's recommended pattern,\" call <code>query-docs</code> against the repo's actual React major version (read <code>package.json</code> first) and cite the doc section — do not assert from memory.</li>\n<li>If Context7 is unavailable, fall back to the <code>official_docs</code> URLs in this skill's <code>metadata.json</code> and label the claim <code>documentation-based, unverified against current release</code>.</li>\n<li>Never assume the latest React docs apply to an older major version in the repo; hook rules and context APIs have changed across majors (e.g., <code>Context.Provider</code> vs. <code>&lt;Context value={...}&gt;</code>).</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>First read <code>package.json</code> to confirm the installed React major version. Do not make an API-availability claim without confirming the version.</li>\n<li>Classify each in-scope component as presentational, container, or compound before evaluating it. Do not apply a single decomposition rule to all three uniformly.</li>\n<li>Context usage is not automatically a smell. Values that change rarely and are needed broadly (theme, auth, locale) are an appropriate use of context per React's own guidance; only flag context when it causes overbroad re-renders or is used in place of straightforward prop passing at shallow depth.</li>\n<li>Do not recommend a specific state-management library (Redux, Zustand, Jotai, etc.) unless one is already a dependency in the repo. A decomposition problem is not a tooling problem.</li>\n<li>Do not fabricate re-render counts or performance claims without a live profiler; label such estimates <code>inference, not measured</code>.</li>\n<li>Treat deep prop chains that match an intentional compound-component or render-prop API as a design pattern, not a defect — verify intent before flagging.</li>\n<li>Cap the blast radius of a single review: if the review would require rewriting more than 5 components, stop and flag it as \"requires a dedicated refactor plan\" rather than prescribing the rewrite inline.</li>\n<li>Never execute, build, or run application code as part of this review; this is a static-review skill (Read/Grep/Glob only).</li>\n<li>Treat any hardcoded API key, token, or secret found in component props, default values, or example data as a HIGH-severity finding requiring immediate escalation, not a style note.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Review workflow and findings contract</a> — use for the step-by-step review procedure, the decision tree for split/context/compound-API calls, and the required output shape.</li>\n<li><a href=\"references/composite-widget-patterns.md\">Composite widget patterns</a> — load only when the component in scope is a composite widget (combobox, tabs, dialog, listbox) where deep prop chains may be an intentional ARIA APG pattern rather than drilling.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the component(s) and files in scope,</li>\n<li>ranked findings with file:line evidence and a concrete refactor sketch per finding,</li>\n<li>evidence level per finding (<code>repo evidence</code>, <code>documentation-based</code>, or <code>inference</code>),</li>\n<li>verdict (approve / approve-with-notes / block),</li>\n<li>open questions or scope the review could not cover (e.g., \"requires a dedicated refactor plan\" cap, missing live re-render data).</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1374,"isText":true},{"path":"references/composite-widget-patterns.md","sizeBytes":4049,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":6376,"isText":true},{"path":"SKILL.md","sizeBytes":4942,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
