Check a page, component or directory against a quick WCAG AA checklist — images, structure, contrast, keyboard, forms, ARIA, motion — reporting pass or fail with quick fixes in the chat. Use when the user wants a fast accessibility check of one piece of code rather than a formal audit. Not for a Figma design or mentoring feedback; see /design-a11y-audit or /coaching-a11y.

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

# Checklist

Run a quick WCAG 2.1 AA accessibility checklist against "$ARGUMENTS". This is a lightweight check — use the full audit workflow (scope → evaluate → report) for comprehensive testing.

## Prerequisites

None — this is a utility skill that can run anytime.

## Process

1. **Read the target:**
   - Read the source code of "$ARGUMENTS" (file, component, or page)
   - If "$ARGUMENTS" is a directory, check all relevant files

2. **Check each category:**

   **Images & Media:**
   - [ ] All images have meaningful alt text (or alt="" if decorative)
   - [ ] Videos have captions
   - [ ] Audio has transcripts

   **Structure:**
   - [ ] Page has one h1
   - [ ] Heading hierarchy is sequential (no skipped levels)
   - [ ] Landmark regions used (main, nav, header, footer)
   - [ ] Lists use proper list elements
   - [ ] Tables have headers

   **Color & Contrast:**
   - [ ] Text contrast ratio >= 4.5:1 (3:1 for large text)
   - [ ] UI component contrast >= 3:1
   - [ ] Color is not the only way information is conveyed

   **Keyboard:**
   - [ ] All interactive elements are keyboard accessible
   - [ ] Focus order is logical
   - [ ] Focus indicator is visible

How to install

The exact contents, by fingerprint

mdr add bromso/singularskills/accessibility-checklist@sha256:f427d9e493ff655f

The line at the top of this page pins the label git:20261029.7f379ee, 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.
