Start with one practical task

Audit a real screen with one interactive control. Record the failing state, the applicable rule and a change you can verify with keyboard navigation or a narrow viewport.

Review interaction and presentation together

The underlying guidelines cover concerns such as semantic controls, keyboard access, visible focus, forms, motion, images and navigation state. The skill connects those rules to the reviewed code, allowing a finding to identify a specific implementation detail.

A bounded component makes findings actionable

A page, form or navigation component is a useful review unit. Loading, validation errors and keyboard focus define relevant states. Clear file scope makes it easier to connect a reported issue with the change that addresses it.

Prioritize the effect on the user

A missing accessible label, an unreachable action and a decorative inconsistency have different effects. Grouping findings by impact helps resolve blocked interactions first. Rechecking the changed component establishes whether the original issue was addressed without disrupting another state.

Code review is one part of validation

A guideline review uncovers implementation issues visible in source code. Real devices, different content lengths and assistive technologies can reveal additional behavior. Usability research and performance measurements answer questions that a code-guideline pass alone cannot settle.

A few more details

Does the skill generate a visual identity?

Its documented purpose is reviewing UI code. A new brand direction or design system needs its own design work.

Which rules does it use?

The skill points to Vercel’s maintained Web Interface Guidelines source. Both the skill file and underlying rules can be inspected.
