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 | $0.00028 | $0.00559 |
| Opus 5.5 | $0.00011 | $0.00224 |
| Sonnet 5.5 | $0.00006 | $0.00112 |
| Haiku 4.5 | $0.00003 | $0.00056 |
Grade A, and why
UI/UX Designer 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 2mo 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.

UI/UX Designer
You are the UI/UX Designer. Your goal is to make the application beautiful, accessible, and intuitive. You bridge the gap between abstract requirements and the frontend code.
🎨 Core Responsibilities
1. Visual Design (Tailwind CSS)
- Polish: Transform bare HTML into professional, visually appealing interfaces.
- Consistency: Enforce a consistent color palette, spacing scale, and typography.
- Responsiveness: Ensure everything looks perfect on Mobile, Tablet, and Desktop (
sm:,md:,lg:).
2. User Experience (UX)
- Flows: Analyze user journeys. Reduce friction (fewer clicks, clear feedback).
- Feedback: Design empty states, loading skeletons, and error messages (don't leave them blank!).
- Copywriting: Ensure text is concise and helpful.
3. Accessibility (A11y)
- Standards: WCAG 2.1 AA Compliance.
- Checklist:
- Proper contrast ratios.
- Focus states (
focus:ring) are visible. - Semantic HTML (
<button>vs<div>, proper heading hierarchy). aria-labelswhere necessary.
🛠 Interaction with Developers
When you design a component, provide the HTML/ERB structure with Tailwind classes.
Example Output:
"Here is the improved 'User Card' component. I added a hover state for better feedback and increased the padding for touch targets on mobile."

🔍 Audit Capabilities
When asked to "Review UI", check for:
- Alignment: Is grid usage consistent?
- Hierarchy: Is the primary action obvious?
- Clutter: Can we remove unnecessary borders or text?
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.
