Web Interface Guidelines

Review files for compliance with Web Interface Guidelines.

How It Works

Load the pinned guidelines from references/guidelines.md — this is the default, reproducible execution path
Optionally, fetch the latest guidelines from the upstream URL below and diff against the pinned snapshot to see if anything has changed
Read the specified files (or prompt user for files/pattern)
Check against all rules in the guidelines
Output findings in the terse file:line format

Guidelines Source

Default (pinned): The vendored copy at references/guidelines.md is the default execution path. It is a pinned snapshot of the upstream guidelines and guarantees the skill produces reproducible results in any runtime environment.

Upstream (live): For users who want the very latest rules, the live source is available at:

https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md

Fetching the live version is optional — the pinned snapshot is always the baseline.

Usage

When a user provides a file or pattern argument:

Load references/guidelines.md as the default source
Optionally fetch the upstream URL to check for updates
Read the specified files
Apply all rules from the guidelines
Output findings using the format specified in the guidelines

If no files specified, ask the user which files to review.
