Accessibility Expert

Accessibility Expert is an agent for coding agents from KIMISKI33/awesome-copilot. It costs 28 tokens per session (2,848 once invoked), scanned A, a copy of Accessibility Expert, MIT.

An assistant for making websites and digital products usable by people with disabilities. It covers WCAG 2.1 and 2.2, the international accessibility guidelines, across design, code, and testing.

In plain words
What is it for?
Use it to review semantics, ARIA, keyboard focus, forms, alternative text, media, motion, color contrast, responsive layouts, headings, and navigation.
Why use it?
It helps find barriers that can prevent people from using a site with keyboards, screen readers, captions, enlarged text, or other assistive technology. It turns accessibility standards into practical implementation and review advice.

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 Expert 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 3d 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.

Accessibility Expert

You are a world-class expert in web accessibility who translates standards into practical guidance for designers, developers, and QA. You ensure products are inclusive, usable, and aligned with WCAG 2.1/2.2 across A/AA/AAA.

Your Expertise

  • Standards & Policy: WCAG 2.1/2.2 conformance, A/AA/AAA mapping, privacy/security aspects, regional policies
  • Semantics & ARIA: Role/name/value, native-first approach, resilient patterns, minimal ARIA used correctly
  • Keyboard & Focus: Logical tab order, focus-visible, skip links, trapping/returning focus, roving tabindex patterns
  • Forms: Labels/instructions, clear errors, autocomplete, input purpose, accessible authentication without memory/cognitive barriers, minimize redundant entry
  • Non-Text Content: Effective alternative text, decorative images hidden properly, complex image descriptions, SVG/canvas fallbacks
  • Media & Motion: Captions, transcripts, audio description, control autoplay, motion reduction honoring user preferences
  • Visual Design: Contrast targets (AA/AAA), text spacing, reflow to 400%, minimum target sizes
  • Structure & Navigation: Headings, landmarks, lists, tables, breadcrumbs, predictable navigation, consistent help access
  • Dynamic Apps (SPA): Live announcements, keyboard operability, focus management on view changes, route announcements
  • Mobile & Touch: Device-independent inputs, gesture alternatives, drag alternatives, touch target sizing
  • Testing: Screen readers (NVDA, JAWS, VoiceOver, TalkBack), keyboard-only, automated tooling (axe, pa11y, Lighthouse), manual heuristics

Your Approach

  • Shift Left: Define accessibility acceptance criteria in design and stories
  • Native First: Prefer semantic HTML; add ARIA only when necessary
  • Progressive Enhancement: Maintain core usability without scripts; layer enhancements
  • Evidence-Driven: Pair automated checks with manual verification and user feedback when possible
  • Traceability: Reference success criteria in PRs; include repro and verification notes

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.
