accessibility-regression-detector skillA
accessibility-regression-detector is agent-read markdown (skill) from community-access/accessibility-agents: Compare audits across commits to find new, fixed and regressed issues..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install
mdr add community-access/accessibility-agents/accessibility-regression-detector@git:20260922.cd88753mdr add community-access/accessibility-agents/accessibility-regression-detector@sha256:7901f6720435b6cePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
