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 | $0.00058 | $0.01333 |
| Opus 5 | $0.00029 | $0.00666 |
| Sonnet 5 | $0.00012 | $0.00267 |
| Haiku 4.5 | $0.00006 | $0.00133 |
Grade A, and why
ux-visual-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 10d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Visual Design
Visual design is not decoration — it is communication. Every spacing decision, color choice, and animation tells the user what matters and what to do next.
Checklist
| Item | Guidance |
|---|---|
| Touch target size | Minimum 44x44pt on iOS, 48x48dp on Android. Non-negotiable for all tappable elements. |
| Empty state UI | Every empty screen shows an illustration or icon, a heading, a short message, and an optional action. Full standards live in ux-error-handling. |
| Font readability | Body text at 16–17sp. Supporting text (subhead, footnote, caption) no smaller than 12sp. Line height between 1.4 and 1.6. |
| Semantic color usage | Green for success, red for errors and destructive actions, yellow for warnings. Consistent throughout. |
| Error color differentiation | Error, warning, and info states are visually distinct from each other, not just color-coded. |
| Text hierarchy | Maximum 3 levels: title, body, caption. Use weight and size to differentiate, not color alone. |
| Design consistency | Every component and screen looks like it belongs to the same family. |
| Active and inactive states | Active vs inactive is communicated through color change or opacity, never color alone. |
| Row spacing | Minimum 8pt padding between list items. Content rows between 56dp and 72dp tall. |
| Micro-interactions | Button press feedback in under 100ms. Meaningful animations on state changes. |
| Avoid excessive animation | Animations are capped at 300ms for transitions. Reduced for lower-end hardware. |
| RTL and LTR layout | Layout mirrors correctly for right-to-left languages. Directional icons flip. |
| 8pt grid system | All spacing values are multiples of 4 or 8 (margin, padding, icon size, gap). |
| Notch and Dynamic Island | Background color extends into the safe area. Notch is not cut off. |
| Dark mode | Dark mode uses a dedicated color palette with elevated surfaces, not just an inverted light theme. |
| Image zoom | Users can view images at full size. Pinch-to-zoom is supported. |
| Image gallery | Swipe between images is supported where multiple images are shown. |
| Consistent dialogs | Alert and modal dialogs are styled the same way across the entire app. |
| Universal icons | Icons carry meaning without requiring a label for most users. |
| Screen transition animation | Screen transitions use smooth, directional animations that reinforce navigation hierarchy. |
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.

ux-visual-design is a skill published in the GitHub repository parhamb/design-skills (21 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 1,333 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.
