Audit a component or page for accessibility issues and fix them
- Works in 4 steps: Perceivable → Operable → Understandable → …

What it does
UI A11y is an agent skill from sickn33/agentic-awesome-skills. Audit a component or page for accessibility issues and fix them
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: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Accessibility
Example prompts
- “/ui-a11y”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit b84d35a. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are css).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
UI A11y loads about 937 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 390 words of instructions outside code blocks.
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.

Accessibility Audit
When to Use
Use this skill when you need audit a component or page for accessibility issues and fix them.
When NOT to use
- For general design system compliance review → use
/ss-review - For Nielsen UX heuristics → use
/ss-audit - For non-StyleSeed code (no
data-slot, no semantic tokens) — assumes StyleSeed conventions - For runtime testing — this is a static code audit, not a screen-reader simulation
Target: $ARGUMENTS
Audit Criteria
WCAG 2.2 AA Compliance
1. Perceivable
- Color contrast: Text must meet 4.5:1 (normal) or 3:1 (large/bold text)
- Check
text-muted-foreground(#717182) onbg-background(#FFFFFF) = 4.6:1 (passes) - Check
text-brandon white (verify contrast with your skin's brand color) - Flag any custom colors that don't meet ratio
- Check
- Non-text contrast: UI controls/graphics must meet 3:1
- Text alternatives: All
<img>needalt, icons needaria-labelwhen meaningful - Color independence: Don't convey info by color alone (add icons/text)
2. Operable
- Touch targets: Minimum 44x44px (
min-h-11 min-w-11)- Common violation:
h-9(36px) buttons — should beh-11 - Icon buttons need explicit size:
w-11 h-11
- Common violation:
- Keyboard navigation: All interactive elements must be keyboard-accessible
- Tab order should be logical
focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2
- Motion: Animations must respect
prefers-reduced-motioncss @media (prefers-reduced-motion: reduce) { *, *::before, *::after { animation-duration: 0.01ms !important; transition-duration: 0.01ms !important; } }
3. Understandable
- Labels: Form inputs must have visible labels or
aria-label - Error messages: Form errors must be programmatically associated (
aria-describedby) - Language:
<html lang="en">(or appropriate language code for your project)
4. Robust
- Semantic HTML: Use appropriate elements (
<button>,<nav>,<main>,<header>) - ARIA: Use Radix UI components (they handle ARIA automatically)
- Roles: Custom interactive elements need proper
roleattributes

| Token | Minimum Contrast | Note |
|---|---|---|
--foreground | 7:1+ | Body text — verify with your skin |
--muted-foreground | 4.5:1+ | Secondary text — verify with your skin |
--brand | 4.5:1+ | Accent — verify with your skin's brand color |
--destructive | 4.5:1+ | Error — verify with your skin |
--success | 3:1+ | Large text/icons only — verify with your skin |
--warning | 4.5:1+ | Warning text — some skins need a darker variant |
Output
- Issues found: List with severity (Critical/Major/Minor)
- Auto-fixes: Apply fixes directly where possible
- Manual review needed: Flag items that need human judgment
Example
User request:
Audit a component or page for accessibility issues and fix them.
Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
