Testing & Quality skills
Browse reusable Agent Skills, each with a clear purpose and practical guidance.
identical-links-same-purpose
Use when reviewing rendered HTML, interactive components, or design-system patterns related to Ensure identical links have consistent destinations. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
image-compression
Use when reviewing image assets, markup, and CDN or build transforms related to Compress images without quality loss. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
image-file-size
Use when auditing the image pipeline, static assets in `public/`, CMS-managed media, or image CDN transforms. Separate file-size problems from dimension mismatches so you can tell whether the issue is compression, format choice, or responsive delivery.
image-optimization
Use when reviewing image assets, markup, and CDN or build transforms related to Optimize all images for web. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
image-redundant-alt
Use when reviewing rendered HTML, interactive components, or design-system patterns related to Avoid redundant image alternative text. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
immutable-patterns
Use when reviewing scripts, client components, bundles, or runtime behavior related to Prefer immutable data patterns. Inspect both source code and the browser execution path so fixes target the real bottleneck or bug.
import-on-interaction
Use when reviewing slow initial loads caused by optional features. Prioritize code that is expensive to download or execute and not required for the first viewport, first input, or core task completion.
input-types
Use when reviewing templates, rendered HTML, or shared components related to Use semantic input type attributes. Validate the final browser-facing markup, not just the source framework abstraction.
