Enforce WCAG 2.2 AA compliance with semantic HTML, ARIA roles, keyboard navigation, and color contrast standards for web UIs. Use when building interactive components, adding form labels, fixing focus traps, or auditing a11y compliance.
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
# Common Accessibility (a11y) Standards ## **Priority: P1 (HIGH)** > Legal req: EU (Web Accessibility Directive), USA (ADA/Section 508). Non-compliance = litigation risk. Minimum: **WCAG 2.2 Level AA**. ## 🏗 Semantic HTML First - Use native HTML before ARIA. `<button>`, `<a>`, `<nav>`, `<main>`, `<section>`, `<form>`, `<label>` convey semantics natively. - Never `<div>`/`<span>` for interactive elements — no keyboard role by default. - Headings (`h1`–`h6`) must form logical outline. One `h1` per page. - `<button>` not `<div onClick>`, `<a>` not `<span onClick>`. ## 🎭 ARIA — Use Sparingly ARIA supplements native HTML when insufficient (e.g., custom widgets). Rules: 1. **No ARIA > Bad ARIA**: If native HTML works, use it. ARIA only adds roles, not behavior. 2. **Required attributes**: Every `role` with required properties must include them (e.g., `role="slider"` needs `aria-valuenow`, `aria-valuemin`, `aria-valuemax`). 3. **Live Regions**: Use `aria-live="polite"` for status messages; `aria-live="assertive"` only for critical alerts. 4. **Labels**: Every form control needs programmatic label (`<label>`, `aria-label`, or `aria-labelledby`). …

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-accessibility@sha256:8ce6d4f589a694c7The line at the top of this page pins the label git:20260929.bdf124b, 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.
