- 404-pageUse when reviewing templates, rendered HTML, or shared components related to Create a custom 404 error page. Validate the final browser-facing markup, not just the source framework abstraction.
- back-forward-cacheUse when reviewing navigation performance, browser lifecycle events, or resume-from-memory behavior. Check the actual browser lifecycle and restore path, not only static code patterns.
- button-nameUse when reviewing rendered HTML, interactive components, or design-system patterns related to Provide accessible names for buttons. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
- definition-listUse when reviewing rendered HTML, interactive components, or design-system patterns related to Use correct definition list structure. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
- focus-orderUse when reviewing rendered HTML, interactive components, or design-system patterns related to Ensure logical focus order. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

- frame-titleUse when reviewing rendered HTML, interactive components, or design-system patterns related to Provide titles for iframes and frames. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
- json-safetyUse when reviewing scripts, client components, bundles, or runtime behavior related to Parse JSON safely with error handling. Inspect both source code and the browser execution path so fixes target the real bottleneck or bug.
- lang-attributeUse when applies to all HTML documents. Check the `<html>` opening tag for a `lang` attribute with a non-empty, valid BCP 47 language code. Also check for `lang` attribute changes on individual elements when the document contains content in multiple languages (inline quotes, foreign terms, multilingual sections). The `lang` attribute is inherited — child elements inherit the language from their nearest ancestor with `lang`.

- specificity-managementUse when reviewing stylesheets, component styles, and responsive behavior related to Keep CSS specificity low and flat. Check the rendered layout across breakpoints and interaction states before proposing a fix.
- videoUse when applies to any page embedding or hosting video content (YouTube, Vimeo, self-hosted). Use when adding video content to a site or auditing structured data coverage.
- viewport-zoomUse when applies to any `<meta name='viewport'>` element in HTML documents. Check the `content` attribute for `user-scalable=no`, `user-scalable=0`, `maximum-scale=1`, or `maximum-scale` values less than 2. This is a common mistake in mobile-first templates and CSS frameworks.
- web-design-guidelinesReview UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".
- webp-formatUse when reviewing image assets, markup, and CDN or build transforms related to Use WebP format with fallbacks. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
