Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Use when reviewing templates, rendered HTML, or shared components related to Use navigation landmark regions. Validate the final browser-facing markup, not just the source framework abstraction.
Use when reviewing TypeScript files for type safety regressions, during code review of functions that handle external data, or when the codebase has ESLint warnings for @typescript-eslint/no-explicit-any.
Use when auditing tsconfig.json for missing safety flags, reviewing code that uses array index access in data processing pipelines, or investigating runtime undefined errors that TypeScript did not catch.
Use when auditing internal link structure or reviewing link attributes. Applies to any site using rel=nofollow on links pointing to pages within the same domain.
Use when reviewing templates, rendered HTML, or shared components related to Provide noscript fallback content. Validate the final browser-facing markup, not just the source framework abstraction.
Use when reviewing image assets, markup, and CDN or build transforms related to Lazy load offscreen images. Check encoded size, rendered size, loading strategy, and above-the-fold impact together. Missing `loading='lazy'` is only a valid finding when you can reasonably tell the image is offscreen or non-critical.
Use when reviewing mobile-first layouts, tablet experiences, fullscreen flows, forms, dashboards, or media interfaces. Check rendered behavior in both portrait and landscape and separate genuine layout constraints from unnecessary orientation assumptions.
Use when auditing slow page loads, heavy assets, or rendering delays related to Keep page load time under 3 seconds. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
