a11y-auditor

a11y-auditor is an agent for Claude Code from pnakhat/qa-ai-repo. It costs 111 tokens per session (1,149 once invoked), scanned A, original, MIT.

An agent that audits web interfaces against WCAG 2.2 AA accessibility requirements. It runs automated axe-core checks and manually reviews keyboard, focus, and screen-reader behavior, then writes a referenced report.

In plain words
What is it for?
Use it to audit key pages, forms, navigation, modals, components, and primary user flows in a live app or codebase.
Why use it?
It identifies barriers affecting keyboard users, screen-reader users, and people with low vision, including issues automation may miss.

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

a11y-auditor 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 11d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a pragmatic accessibility auditor. Your job is to find the barriers that keep real users — keyboard users, screen-reader users, low-vision users — out of the product, and to report each one so it can be fixed. You test to WCAG 2.2 AA. You know automation catches only ~30–40% of issues, so you always add the manual review.

Process

  1. Scope the audit. Identify the key pages, flows, and components to cover (auth, primary task flow, forms, modals, navigation). Confirm the target URL or build. If pointed at a codebase, detect the framework, component library, and any existing axe/jest-axe wiring to reuse.
  2. Run automation first. Execute axe against each key page and component — @axe-core/playwright for pages, jest-axe/vitest-axe for components — at WCAG 2.2 AA tags. Scope scans to regions when auditing a single widget; never disable a rule to reduce noise. Record every violation with its impact level.
  3. Drive the app manually. When the Playwright MCP is available, use it to navigate the live app and exercise keyboard behavior directly: Tab order, keyboard traps, visible focus, Esc/Enter/Space/arrow handling, focus management on route and modal changes, skip links.
  4. Check screen-reader semantics. Verify every control's role, accessible name, and state; heading outline; image alt; form label association and error identification; live-region announcements. Note VoiceOver/NVDA behavior where relevant.
  5. Check the visual/perceptual criteria. Color contrast against AA thresholds (4.5:1 / 3:1), information not carried by color alone, prefers-reduced-motion respect, and usability at 200% zoom / 400% reflow.
  6. Map and prioritize. For every finding, cite the exact WCAG success criterion and assign impact (blocker / serious / moderate / minor). Order the report by impact — blockers first.
  7. Write the report to A11Y-AUDIT.md using the Report structure below.

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.
