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.

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 | $0.00048 | $0.02280 |
| Opus 5.5 | $0.00019 | $0.00912 |
| Sonnet 5.5 | $0.00010 | $0.00456 |
| Haiku 4.5 | $0.00005 | $0.00228 |
Grade A, and why
qa-design 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 16d 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.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI/UX Design Audit
Objective
Audit a web interface against 100+ rules covering accessibility, forms, animations, typography, images, performance, navigation, dark mode, and internationalization.
Audit categories
┌──────────────────────────────────────────────────────────────────┐
│ UI/UX AUDIT │
├──────────────────────────────────────────────────────────────────┤
│ │
│ 1. ACCESSIBILITY ARIA, contrast, focus, keyboard │
│ 2. FORMS Validation, feedback, autofill │
│ 3. ANIMATIONS Performance, reduced-motion, timing │
│ 4. TYPOGRAPHY Hierarchy, readability, responsive │
│ 5. IMAGES Alt text, lazy loading, formats │
│ 6. UI PERFORMANCE Layout shift, first paint, bundle │
│ 7. NAVIGATION Breadcrumbs, mobile menu, deep links │
│ 8. DARK MODE CSS variables, images, contrast │
│ 9. TOUCH INTERACTIONS Target size, swipe, gestures │
│ 10. INTERNATIONALIZATION RTL, dates, plurals, translations │

1. Accessibility
Critical rules
| # | Rule | Verification |
|---|---|---|
| A1 | Minimum contrast 4.5:1 (normal text) | Check CSS colors |
| A2 | Minimum contrast 3:1 (large text, icons) | Check CSS colors |
| A3 | Labels on all form fields | <label for=""> or aria-label |
| A4 | Alt text on all informative images | <img alt=""> non-empty |
| A5 | Full keyboard navigation | Tab, Enter, Escape, Arrow keys |
| A6 | Visible focus on interactive elements | :focus-visible style |
| A7 | Correct ARIA roles | role, aria-* attributes |
| A8 | No purely visual content | Text alternatives |
| A9 | Logical heading structure | h1 > h2 > h3, no skipping |
| A10 | Skip to content link | First focusable element |
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.
