Third-party skill — Vercel Web Interface Guidelines compliance (focus, forms, animation, copy). Use when the user names Vercel or web interface guidelines. Generic a11y → audit-accessibility.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Web Interface Guidelines

> **Third-party skill** (upstream-maintained). See [ATTRIBUTION.md](ATTRIBUTION.md).  
> Upstream: [vercel-labs/web-interface-guidelines](https://github.com/vercel-labs/web-interface-guidelines) · [vercel.com/design/guidelines](https://vercel.com/design/guidelines) · Local name: `thirdparty-web-interface-guidelines`

Review target files for compliance. Read files, check against rules below. Output concise but comprehensive—sacrifice grammar for brevity. High signal-to-noise.

When the user provides specific files or patterns, review those. Otherwise ask which files to review.

## Rules

### Accessibility

- Icon-only buttons need `aria-label`
- Form controls need `<label>` or `aria-label`
- Interactive elements need keyboard handlers (`onKeyDown`/`onKeyUp`)
- `<button>` for actions, `<a>`/`<Link>` for navigation (not `<div onClick>`)
- Images need `alt` (or `alt=""` if decorative)
- Decorative icons need `aria-hidden="true"`
- Async updates (toasts, validation) need `aria-live="polite"`
- Use semantic HTML (`<button>`, `<a>`, `<label>`, `<table>`) before ARIA
- Headings hierarchical `<h1>`–`<h6>`; include skip link for main content

How to install

The exact contents, by fingerprint
mdr add kensaurus/skills/thirdparty-web-interface-guidelines@sha256:f20b470d9493e4ea

The line at the top of this page pins the label git:20261001.3fce9fb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
