accessibility-audit

accessibility-audit is a skill for Claude Code, Codex from varutasu/agent-pipeline. It costs 0 tokens per session (2,856 once invoked), scanned A, original, MIT.

A review process for checking a user interface against WCAG 2.2, accessibility guidelines for making websites and apps usable by people with disabilities. It produces findings ranked from severity 0 to 4 and links them to specific WCAG requirements.

In plain words
What is it for?
Use it to audit a UI change or surface, check whether a screen reader can use it, investigate a WCAG criterion, or review interactive changes before shipping. It can also suggest code changes for issues that are fixable.
Why use it?
It identifies accessibility problems in interactive interfaces before release, including issues affecting keyboard users, screen readers, forms, navigation, modals, dynamic content, and media.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

accessibility-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.


name: accessibility-audit description: >- Run a WCAG 2.2 accessibility audit on a UI change or surface. Produces a severity-ranked findings report keyed to WCAG success criteria, with code diffs for the fixable cases. Use when role-a11y-auditor is invoked, when the user asks for an a11y review, before shipping a UI convoy, or whenever a change touches anything interactive (forms, navigation, modals, dynamic content, media). Skip if skip: a11y is set in the convoy or the change is server/infra-only.

Accessibility audit

Five-layer audit framework keyed to WCAG 2.2 (W3C, October 2023). Outputs a severity 0–4 findings list, an executive summary, and code-diff suggestions for fixable issues. The default rubric below covers the cases that actually fail in production; the deep reference at references/wcag-2.2-checklist.md covers all 86 success criteria for completeness.

When to invoke

  • Automatic: by role-a11y-auditor when a convoy's PR draft touches app/**, components/**, or any UI surface.
  • Manual: when the user says "audit this for a11y", "check accessibility", "can a screen reader use this", or names a WCAG criterion (2.1.1, 1.4.3, etc.).
  • Pre-merge: when an audit fan-out runs (/multitask role-reviewer + role-security-auditor + role-design-system-auditor + role-a11y-auditor per the multitask playbook).

Severity scale

Severity Meaning Treatment
4 — Blocker WCAG Level A failure on a critical path (auth, checkout, primary navigation). Users on AT cannot complete the journey. Block merge. File as a child task under the audit document (per Phase 2b).
3 — Major WCAG Level AA failure, or Level A failure on a non-critical path. AT users hit a workaround or degraded experience. File as child task. Strongly recommend fix before merge.
2 — Moderate WCAG Level AAA failure, or AA on a low-traffic surface, or AT-specific friction not codified in WCAG (e.g. confusing announcement order). Inline in audit doc; create task only if pattern repeats.
1 — Minor Polish item: improved labels, redundant ARIA cleanup, focus order optimization. Inline only.
0 — Info Note for the maintainer; not a defect. Inline only.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
