ui-accessibility

ui-accessibility is a skill for Claude Code, Codex from volomydyr/design-engineer-plugin. It costs 38 tokens per session (1,351 once invoked), scanned A, original, MIT.

A review guide for checking whether designs and interfaces work for people with different abilities. It covers color contrast, touch target size, and support for screen readers, which read interface content aloud.

In plain words
What is it for?
Use it to review Figma designs, audit implemented screens, test a live application, or examine a specific component for accessibility issues.
Why use it?
It helps find barriers that can make an interface difficult or impossible to use, while also improving usability for everyone.

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

ui-accessibility 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 5d 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 Review

Why This Matters

Accessibility is a UX improvement, not just a compliance requirement. Principles like Fitts's Law (larger targets are easier to hit) and Cognitive Load theory (simpler interfaces reduce mental effort) apply to every user – not just those with disabilities. Building accessible products creates better experiences for everyone.

Interaction Method

If AskUserQuestion is available, use it for all prompts below.

If not, present each question as a numbered list and wait for a reply before proceeding. For multiSelect questions, accept comma-separated numbers (e.g. 1, 3). Never skip or auto-answer without explicit user consent.


Step 1: Determine Review Scope

question: "What are you reviewing for accessibility?"
header: "Review Scope"
options:
  - label: "Figma designs (pre-implementation)"
    description: "Check designs before code is written"
  - label: "Implemented screens (code audit)"
    description: "Audit existing code for accessibility issues"
  - label: "Live application (URL or device)"
    description: "Test a running application"
  - label: "Specific component"
    description: "Focus on one component or interaction"
  - label: "HTML prototype"
    description: "Check an HTML prototype file for accessibility issues"

When "HTML prototype" is selected, read the HTML file at the path the user provides (default: .design-engineer-plugin/prototype/prototype.html). Run the full accessibility checklist with particular attention to contrast ratios, touch/click target sizes, keyboard navigation, screen reader support (semantic HTML, ARIA labels), and heading hierarchy.


Step 2: Run the Accessibility Audit

Use the comprehensive checklist from accessibility-checklist.md covering:

Touch and Click Targets

  • Minimum tap target size: 56 points (based on Fitts's Law – smaller targets require more precision and slow users down)
  • Adequate spacing between interactive elements to prevent accidental taps
  • Touch targets that extend beyond visible boundaries where needed for small icons

Changes

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.
