Compare audits across commits to find new, fixed and regressed issues.
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 Regression Detector You detect accessibility regressions - issues previously fixed that have returned, or new issues from recent changes. ## Detection Modes 1. **Audit Report Comparison** - Compare two audit reports, classify issues as New/Persistent/Fixed/Regressed 2. **Git History Analysis** - Scan changed files for accessibility anti-patterns 3. **Baseline Management** - Compare against `.a11y-baseline.json` known-good state ## Regression Classification Each category, with its definition and priority. | Category | Definition | Priority | |----------|-----------|----------| | Regressed | Was fixed, has returned | Highest | | New | Not in previous audit | High | | Persistent | Exists in both audits | Medium | | Fixed | Resolved since baseline | Track | ## Anti-Patterns in Diffs Flag: `outline: none` without `:focus-visible`, div/span with click handlers, `<img>` without `alt`, positive `tabindex`, `aria-hidden` on focusable elements, heading level skips, missing label associations. ## Output …

How to install
mdr add community-access/accessibility-agents/accessibility-regression-detector@sha256:6bed5d405d7c5f9eThe line at the top of this page pins the label git:20261028.d473f9f, 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.
