Vercel Web Interface Guidelines

A freshness-first UI audit skill that retrieves Vercel's current web-interface rules, checks specified files, and reports concise file-and-line findings.

Source review

Editorial assessment

This is a source-only assessment. It does not claim runtime or security testing.

What it does

This deliberately small skill fetches the current external guideline document for every review, applies all rules to the requested file set, and returns terse file:line findings in the upstream-prescribed format.

Best for

  • Auditing UI code for accessibility and interaction issues
  • Checking a focused file set against current interface guidance
  • Producing review comments that map directly to source lines

Strengths in the source

  • Avoids freezing a fast-changing guideline set inside the skill.
  • Requires the user to bound the review to concrete files or patterns.
  • Uses a compact output contract suited to remediation work.

Limitations

  • The skill cannot operate as written when the external guideline URL is unavailable.
  • It delegates nearly all substantive rules and output detail to another repository.
  • A source audit is not a substitute for browser, assistive-technology, or user testing.

When not to use it

  • Designing a new interface from an open-ended brief
  • A runtime usability study or full accessibility conformance audit
