ux-a11y

ux-a11y is a command for Claude Code from Laith0003/ux-skill. It costs 133 tokens per session (3,483 once invoked), scanned A, original, MIT.

A WCAG 2.1 AA accessibility audit for a webpage or interface, plus practical checks for common usability barriers. WCAG is a set of guidelines for making websites usable by people with disabilities.

In plain words
What is it for?
Use it to inspect a live URL, code file, screenshot, or markup for keyboard access, screen-reader semantics, ARIA, focus, contrast, and related accessibility concerns.
Why use it?
It identifies accessibility problems with severity, evidence, and suggested fixes, including issues that automated checks may miss.

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions subagents.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is || bash bin/ux-lint.sh <user-supplied-path>.

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

ux-a11y scanned grade A with 1 finding 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.

/ux-a11y

You are running the /ux-a11y command from the ux plugin. The job is a structured WCAG 2.1 AA audit of a surface, plus the common-courtesy checks that pass automated tools but still hurt real users.

When to use

Triggers: "accessibility check", "WCAG audit", "is this accessible", "a11y review", "screen reader test", "keyboard nav check", "color contrast", "ARIA review", "make this accessible".

Use whenever a surface is touched by users beyond the team, especially before shipping any production change. Also use proactively after a redesign — accessibility regressions are the most common silent failure.

Input

One of: a URL, an absolute file path (Blade view, JSX, HTML), a screenshot, a code snippet. If a live URL is available, prefer it — automated tools and keyboard testing only work on live surfaces. If only static markup is available, the audit will be partial and you must flag what could not be verified.

Process

1. Identify the surface mode

  • Live URL → can verify contrast computationally, keyboard tab order, focus visibility, ARIA in DOM, dynamic states.
  • Code/file → can verify semantic HTML, ARIA attributes, alt text presence, contrast against declared colors, focus management code paths.
  • Screenshot only → can verify visual contrast (sampled), focus visibility if shown, color-not-only, dynamic-type tolerance. Cannot verify keyboard, screen reader, or dynamic states.

Surface the mode at the top of the report so the user knows what could not be verified.

2. Run the 11-point checklist

For each item, check the relevant WCAG success criterion (cite the SC number) and decide pass / fail / partial / not-verifiable.

1. Color contrast (WCAG 1.4.3, 1.4.11)
  • Body text: ≥ 4.5:1 against its background.
  • Large text (18pt regular or 14pt bold): ≥ 3:1.
  • Non-text UI (focus rings, icons, form borders): ≥ 3:1.
  • Compute ratios; do not eyeball.
2. Keyboard navigation (WCAG 2.1.1, 2.1.2)
  • Every interactive element reachable via Tab in a sensible order.
  • No keyboard traps (modals, custom widgets).
  • Custom widgets respond to expected keys (Esc closes, arrows navigate menus).

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.
