A knowledge base of the rationale, judgment lines, how to build, and how to read automated checks for each WCAG 2.2 success criterion. Used in implementation, review, and auditing to look up the relevant file by success criterion or component.
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
[日本語版 (Japanese)](./SKILL.ja.md) # Accessibility Knowledge Base A reference knowledge base that collects, per success criterion, "what the judgment is based on". It does not restate the definitions of WCAG success criteria or the ARIA specification (the agent is assumed to know them). What it does write down is: which parts of the Understanding documents to hold onto, the judgment lines for interpretation, how to build so the judgment lines are met, and what automated checks can and cannot decide. This skill does not do work on its own. The implementation, review, and audit skills use it to read only the files for the success criteria they need. ## How to look things up 1. **When you know the success criterion number**: read `references/criteria/<number>.md` (for example `references/criteria/1.1.1.md`). The list is in [references/index-by-criterion.md](./references/index-by-criterion.md). 2. **When searching by component type** (when writing or reviewing code): use [references/index-by-component.md](./references/index-by-component.md) to find, from the component (button, link, image, dialog, and so on), the success criteria that apply to it, then read each file. …

How to install
mdr add masup9/a11y-specialist-skills/a11y-knowledge@sha256:065cfa08f7e4cde7The line at the top of this page pins the label git:20261105.2983584, 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.
