a11y-audit is a skill for Claude Code, Codex from sawrus/agent-guides. It costs 0 tokens per session (410 once invoked), scanned A, original, MIT.

An accessibility audit checks whether interactive interfaces can be used by people with different abilities, including people who use keyboards or screen readers. It covers labels, keyboard focus, dialog roles, and announcements for changing content.

In plain words
What is it for?
Use it when building interactive components, reviewing a pull request, or fixing accessibility lint errors involving labels, icon buttons, modal focus, ARIA roles, or dynamic messages.
Why use it?
It finds interface problems that can prevent users from understanding or operating controls. Fixing these issues makes forms, buttons, dialogs, and status messages easier to use.

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-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 9d 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.

What it actually says

Skill: Accessibility Audit & Remediation

When to load

When building interactive components, reviewing a PR for accessibility, or fixing a11y lint errors.

Most Common Violations & Fixes

1. Icon-only button without label

// ❌
<button onClick={onClose}><CloseIcon /></button>

// ✅
<button onClick={onClose} aria-label="Close dialog">
  <CloseIcon aria-hidden="true" />
</button>

2. Input without label

// ❌
<input type="email" placeholder="Email address" />

// ✅
<label htmlFor="email">Email address</label>
<input id="email" type="email" placeholder="[email protected]" />

3. Modal focus management

const Modal = ({ isOpen, onClose, children }: ModalProps) => {
  const firstFocusableRef = useRef<HTMLButtonElement>(null);
  useEffect(() => {
    if (isOpen) firstFocusableRef.current?.focus();
  }, [isOpen]);

  return isOpen ? (
    <div role="dialog" aria-modal="true" aria-labelledby="dialog-title">
      {children}
      <button ref={firstFocusableRef} onClick={onClose}>Close</button>
    </div>
  ) : null;
};

4. Dynamic content announcements

const StatusMessage = ({ message }: { message: string }) => (
  <div aria-live="polite" aria-atomic="true" className="sr-only">
    {message}
  </div>
);

Keyboard Navigation Checklist

  • Tab order follows visual reading order (no tabindex > 0)
  • Custom dropdown: Arrow keys navigate, Escape closes, Enter selects
  • Modals: Focus trapped inside; Escape closes; focus returns to trigger
  • All hover interactions have keyboard equivalent

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.
