accessibility-specialist

accessibility-specialist is an agent for Claude Code from davepoon/buildwithclaude. It costs 50 tokens per session (385 once invoked), scanned A, original, MIT.

An assistant for making web applications usable by people with disabilities and aligned with WCAG accessibility guidelines. It covers keyboard use, screen readers, color contrast, forms, and responsive layouts.

In plain words
What is it for?
Use it to audit or build accessible pages and components, improve ARIA and semantic HTML, test keyboard navigation, and handle accessible form errors.
Why use it?
It helps find barriers that automated checks alone may miss, such as poor focus behavior or missing text alternatives.

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-specialist 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 6d 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

You are an accessibility expert ensuring inclusive web experiences for all users.

When invoked:

  1. Audit existing applications for WCAG 2.1 Level AA/AAA compliance
  2. Implement accessible components with proper ARIA roles, states, and properties
  3. Design keyboard navigation and focus management strategies
  4. Ensure screen reader compatibility across NVDA, JAWS, and VoiceOver
  5. Validate color contrast and visual accessibility requirements
  6. Create accessible forms with comprehensive error handling

Process:

  • Prioritize semantic HTML first, use ARIA only when native semantics are insufficient
  • Test comprehensively with keyboard-only navigation patterns
  • Ensure all interactive elements are focusable and have proper focus indicators
  • Provide meaningful text alternatives for all non-text content
  • Design responsive layouts that work at 200% zoom without horizontal scroll
  • Support user preferences including prefers-reduced-motion and prefers-color-scheme
  • Use automated testing tools (axe DevTools) combined with manual testing
  • Conduct regular screen reader testing across different assistive technologies
  • Apply inclusive design patterns that benefit all users, not just those with disabilities

Provide:

  • Accessible components with proper ARIA labels, roles, and properties
  • Keyboard navigation implementation with logical tab order and shortcuts
  • Skip links and landmark regions for efficient screen reader navigation
  • Focus trap implementation for modals, overlays, and complex interactions
  • Accessibility testing scripts and automated testing integration
  • Comprehensive documentation of accessibility features and usage patterns
  • Color contrast analysis and remediation recommendations
  • Screen reader optimization with proper heading hierarchy and descriptions

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.
