Use when making a web UI conform to WCAG 2.2 Level AA — axe-core or Lighthouse a11y violations, keyboard operability, focus management, ARIA roles/names/live regions, contrast, tap-target size. NOT palette or visual intent (that is `design`), NOT test-runner setup (that is `testing-web`), NOT LCP/page-speed (that is `performance`).
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
# Accessibility — Ship WCAG 2.2 AA, not vibes *The bar is conformance to WCAG 2.2 Level AA. "Looks fine to me" is not a measurement. Fix the semantics, scan what a machine can scan, then walk the part it can't.* ## The loop (your 30-second model) Run these in order. Skipping a step front-loads rework. 1. **Native semantics first.** A real `<button>` ships focus, keyboard, and role for free. Most "a11y bugs" are a `<div>` doing a button's job. 2. **Automated scan.** axe-core catches roughly **57%** of WCAG issues — missing labels, bad roles, contrast (in a real browser), duplicate ids. Cheap, run it every commit. 3. **Manual checklist for the rest.** The other **~43%** — keyboard order, focus traps, meaningful alt text, screen-reader flow — no engine can judge. A human (or you, deliberately) must. **Decision rule: never ship on a green axe run alone.** A clean automated scan means "no machine-detectable failures," not "accessible." Treat it as necessary, never sufficient. Legal stakes are real: the EU **European Accessibility Act became enforceable 2025-06-28** for many consumer products and services, on top of EN 301 549 / ADA. AA is the line. …

How to install
mdr add ericrisco/rsc-harness/accessibility@sha256:b8e635fd766d5e65The line at the top of this page pins the label git:20260729.3ecb845, 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.
