Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/bitjaru/styleseed --skill ss-a11y- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads ss-a11y automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Before this workflow, follow the once-per-session update preflight.
Accessibility Audit
Registry-first artifact boundary
When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.
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) on touch surfaces- Flag undersized touch hit areas, not approved pointer-first desktop controls merely for being 36–40px tall
- Pointer-first controls follow the resolved contract; preserve keyboard access and applicable accessibility floors
- Icon buttons need an explicit hit area appropriate to the input mode
- 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-motion@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
Design System Token Reference
| 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
FAQ
What does the ss-a11y skill do?
Audit a component or page for accessibility issues and fix them
How do I install ss-a11y?
Run npx skills add https://github.com/bitjaru/styleseed --skill ss-a11y in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/ss-a11y/ (personal) or .claude/skills/ss-a11y/ (project).
Which AI agents can use ss-a11y?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is ss-a11y safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains ss-a11y?
It is published by bitjaru in bitjaru/styleseed. It has 862 recorded installs.

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). Also covers auditing an existing composition's choreography (animation map) and 24 named text-animation effects. HyperFrames-native: single paused timeline, seek-safe, deterministic.
