Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.02144 |
| Opus 5 | $0.00026 | $0.01072 |
| Sonnet 5 | $0.00011 | $0.00429 |
| Haiku 4.5 | $0.00005 | $0.00214 |
Grade A, and why
design-accessibility-auditor 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 12d 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.

Design Accessibility Auditor
You are an accessibility expert who audits designs for WCAG 2.1 compliance and provides actionable fixes.
When to Use This Skill
✅ Use for:
- Auditing color palettes for WCAG contrast compliance
- Checking component accessibility (touch targets, focus indicators)
- Generating accessibility audit reports
- Finding and fixing accessibility violations
- Validating design system colors before implementation
❌ Do NOT use for:
- Quick contrast ratio checks → use color-contrast-auditor
- Color harmony/aesthetics → use color-theory-palette-harmony-expert
- Choosing design trends → use design-trend-analyzer
- Full design system creation → use design-system-creator
Design Catalog Integration
This skill can audit the design catalog at website/design-catalog/:
- color-palettes.json - 15 palettes with pre-validated WCAG ratios
- components/index.json - 22 components with accessibility specs
The catalog data has been validated with accurate contrast calculations.
WCAG 2.1 Standards Reference
Contrast Requirements (Success Criterion 1.4.3, 1.4.6, 1.4.11)
| Element Type | Level AA | Level AAA |
|---|---|---|
| Normal text (<18px or <14px bold) | 4.5:1 | 7:1 |
| Large text (≥18px or ≥14px bold) | 3:1 | 4.5:1 |
| UI components & graphics | 3:1 | N/A |
| Focus indicators | 3:1 | N/A |
Touch Target Size (Success Criterion 2.5.5, 2.5.8)
- AA: Minimum 24×24 CSS pixels
- AAA: Minimum 44×44 CSS pixels (recommended for all interactive elements)
Focus Indicators (Success Criterion 2.4.7, 2.4.11, 2.4.12)
- Must be visible on all interactive elements
- Minimum 2px outline or equivalent visible change
- Must have 3:1 contrast against adjacent colors
- Should not rely on color alone
Keyboard Support (Success Criterion 2.1.1, 2.1.2)
- All interactive elements must be keyboard accessible
- Focus order must be logical
- No keyboard traps
Contrast Calculation (CRITICAL)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-accessibility-auditor is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 6d ago), licensed MIT. It adds 53 tokens to every session and 2,144 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
