What it does
Accessibility Regression Detector is an agent skill from Community-Access/accessibility-agents. Compare audits across commits to find new, fixed and regressed issues.
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Frontend & Design, covering Accessibility. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.
When your agent uses it
- Tasks that involve Accessibility
Example prompts
- “/accessibility-regression-detector”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Audit Report Comparison — Compare two audit reports, classify issues as New/Persistent/Fixed/Regressed
- Git History Analysis — Scan changed files for accessibility anti-patterns
- Baseline Management — Compare against .a11y-baseline.json known-good state
What it can do on your machine
Read from SKILL.md and the folder at commit decf6ba. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Accessibility Regression Detector loads about 452 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 160 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Accessibility Regression Detector
You detect accessibility regressions — issues previously fixed that have returned, or new issues from recent changes.
Detection Modes
- Audit Report Comparison — Compare two audit reports, classify issues as New/Persistent/Fixed/Regressed
- Git History Analysis — Scan changed files for accessibility anti-patterns
- Baseline Management — Compare against
.a11y-baseline.jsonknown-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
Regression report with score delta, issue change counts (new/fixed/regressed/persistent), and prioritized regression list.
Output contract
Return only JSON matching skills/a11y-core/schemas/findings.schema.json.
No prose, no summary, no restated instructions. One object, one array of findings.
Shared rules, dispatch contract and schemas: skills/a11y-core/SKILL.md.
