Enforce Web Interface Guidelines

The skill reviews files for compliance with the Web Interface Guidelines by fetching the rules fresh before every review rather than relying on a baked-in copy. It fetches the latest guidelines from the source URL, reads the specified files (or asks the user which files/pattern to review if none were given), checks the files against every rule in the fetched guidelines, and outputs findings in the terse file:line format that the fetched guidelines themselves specify - meaning the output format is defined by the live document, not hardcoded into the skill.

Use it when files need to be checked against the Web Interface Guidelines for compliance. It is not a substitute for environment-specific validation, testing, or expert review, and it stops to ask for clarification when required inputs, permissions, safety boundaries, or success criteria are missing.

Input is a file or file-pattern argument identifying what to review; if none is given, the skill asks the user which files to review. Output is a list of findings in the terse file:line format specified by the fetched guidelines document.

Developers and reviewers who want file changes checked against the current Vercel Web Interface Guidelines automatically, without manually re-reading the guidelines document or risking a stale local copy of the rules.
