accessibility-implementation

A development guide for making websites and applications usable by people with disabilities, including keyboard users and screen-reader users. It covers WCAG accessibility rules, ARIA labels and roles, focus behavior, and accessibility testing.

In plain words
What is it for?
Use it to implement accessible components, keyboard navigation, focus traps, skip links, screen-reader announcements, ARIA states, and automated or manual accessibility checks.
Why use it?
It helps identify and fix barriers such as missing labels, poor keyboard navigation, or unclear screen-reader announcements. This makes interfaces easier to use and helps meet recognized accessibility standards.

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-implementation 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 2d 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 Implementation

Technical implementation of WCAG guidelines, ARIA patterns, and assistive technology support.

When to Use This Skill

Use this skill when... Use design-tokens instead when...
Implementing WCAG 2.1/2.2 success criteria in code Setting up CSS custom properties or theme systems
Adding ARIA roles, states, or live regions Defining semantic colour tokens used by themes
Wiring keyboard navigation, focus traps, or skip links Organizing primitive/semantic/component token tiers
Auditing components with axe-core, jest-axe, or Playwright Implementing light/dark mode token overrides

Core Expertise

  • WCAG Compliance: Implementing WCAG 2.1/2.2 success criteria in code
  • ARIA Patterns: Correct usage of roles, states, and properties
  • Keyboard Navigation: Focus management, key handlers, logical tab order
  • Screen Readers: Content structure, announcements, live regions
  • Testing: Automated and manual accessibility testing

WCAG Quick Reference

Level A (Must Have)

Criterion Implementation
1.1.1 Non-text Content alt for images, labels for inputs
1.3.1 Info and Relationships Semantic HTML, ARIA relationships
2.1.1 Keyboard All interactive elements keyboard accessible
2.4.1 Bypass Blocks Skip links, landmarks
4.1.2 Name, Role, Value ARIA labels, roles for custom widgets

Level AA (Should Have)

Criterion Implementation
1.4.3 Contrast (Minimum) 4.5:1 text, 3:1 large text
1.4.11 Non-text Contrast 3:1 for UI components
2.4.6 Headings and Labels Descriptive, hierarchical headings
2.4.7 Focus Visible Visible focus indicator (2px+ outline)

ARIA Patterns

Buttons and Links

<!-- Custom button -->
<div role="button" tabindex="0"
     aria-pressed="false"
     onkeydown="handleKeyDown(event)">
  Toggle Feature
</div>

<!-- Icon button (needs accessible name) -->
<button aria-label="Close dialog">
  <svg aria-hidden="true">...</svg>
</button>

<!-- Link vs button -->
<!-- Use link for navigation, button for actions -->
<a href="/page">Go to page</a>
<button type="button">Submit form</button>

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.

accessibility-implementation is a skill published in the GitHub repository laurigates/claude-plugins (54 stars, last pushed 3d ago), licensed MIT. It adds 48 tokens to every session and 3,209 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
