Browse reusable Agent Skills, each with a clear purpose and practical guidance.
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 auditing an XML sitemap or diagnosing indexing issues. Applies to any site where noindex meta tags or X-Robots-Tag headers may be applied to URLs also listed in the sitemap.
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 rendered HTML, interactive components, or design-system patterns related to Provide alternative text for objects. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
Use when adding PWA capabilities, implementing a service worker, or improving the experience for users on unreliable network connections.
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 auditing Open Graph tags or generating og:image assets. Applies to any page that may be shared on social networks or messaging platforms.
