What it does

Accessibility Patterns is an agent skill from vibeeval/vibecosystem. WCAG 2.2 AA compliance, ARIA patterns, keyboard navigation, screen reader optimization

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Accessibility. The repository describes itself as: AI software team for Claude Code - 138 agents, 295 skills, 73 hooks. Self-learning, multi-agent swarm, autonomous skill evolution. The licence is MIT.

Requirements

Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 3b763b1. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npx
- lighthouse
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Accessibility Patterns loads about 943 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 174 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~943

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Motion Preferences

css

@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after {
    animation-duration: 0.01ms !important;
    transition-duration: 0.01ms !important;
  }
}

Testing

bash

# axe-core (automated)
npx @axe-core/cli https://localhost:3000

# Lighthouse accessibility audit
lighthouse --only-categories=accessibility https://localhost:3000

Checklist

Semantic HTML (headings, landmarks, lists)
Alt text on all images
Color contrast 4.5:1 (text), 3:1 (UI)
Keyboard navigable (tab order logical)
Focus visible indicator
Skip link to main content
Form labels and error messages
ARIA roles where needed
prefers-reduced-motion respected

Anti-Patterns

<div onclick> instead of <button>
Color-only information (add icon/text)
Auto-playing video/audio
Removing focus outline without replacement
Using ARIA when native HTML suffices
