.claude/skills/a11y-audit/SKILL.md

a11y-audit is a skill for Claude Code from SAP/fundamental-ngx. It costs 15 tokens per session (876 once invoked), scanned A, original, Apache-2.0.

An accessibility audit for checking a component and its examples against WCAG AA, a commonly used set of web accessibility guidelines.

In plain words
What is it for?
Use it to inspect semantic HTML, ARIA attributes, keyboard navigation, and other accessibility requirements in a component or folder.
Why use it?
It helps find barriers that can prevent people from using the interface with keyboards, assistive technology, or different visual settings. It checks both the implementation and its documented examples.

About the project

Fundamental Library for Angular is an SAP-maintained Angular component library implementing SAP's design system and wrapping UI5 Web Components. Angular developers use its typed UI components and higher-level composites to build SAP-style web interfaces. Catalogue entries provide skills, agents, instructions, and a rule for working with the library.

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

a11y-audit 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 11d 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.

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Accessibility Audit: $ARGUMENTS

If $ARGUMENTS is empty, ask the user for a component path or folder before proceeding.

Audit the component(s) at $ARGUMENTS for WCAG AA compliance. Check both the component implementation and its documentation examples.

Checklist

1. Semantic HTML

  • Interactive elements use native HTML (<button>, <a>, <input>) — not <div> or <span> with click handlers
  • Lists use <ul>/<ol>/<li> — not divs with list styling
  • Headings use <h1>-<h6> with correct hierarchy
  • Tables use <table>, <thead>, <tbody>, <th> with scope

2. ARIA Attributes

  • Custom interactive components have appropriate role attribute
  • aria-label or aria-labelledby on elements without visible text
  • aria-expanded on expandable triggers (menus, dropdowns, accordions)
  • aria-selected on selectable items (tabs, list items)
  • aria-disabled synced with disabled input
  • aria-haspopup on elements that open popups/menus
  • aria-live regions for dynamic content updates
  • No redundant ARIA (e.g. role="button" on <button>)

3. Keyboard Navigation

  • All interactive elements reachable via Tab
  • Tab order follows visual/logical order
  • Arrow keys for navigation within composite widgets (menus, tabs, grids)
  • Enter/Space activates buttons and links
  • Escape closes modals, popups, and dropdowns
  • Focus trapped inside modals/dialogs when open
  • Focus returns to trigger element when popup/modal closes
  • No keyboard traps (user can always Tab out)

4. Focus Management

  • Focus indicator visible on all interactive elements (:focus-visible styles)
  • Focus moves to new content when dynamically added (e.g. dialog opens)
  • tabindex="0" only on elements that need to be in tab order
  • tabindex="-1" for programmatically focusable elements not in tab order
  • No positive tabindex values (breaks natural tab order)

5. Color and Contrast

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.
