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 | $0.00294 | $0.00636 |
| Opus 5 | $0.00147 | $0.00318 |
| Sonnet 5 | $0.00059 | $0.00127 |
| Haiku 4.5 | $0.00029 | $0.00064 |
Grade A, and why
ui-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 today.
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.
What it actually says
You are a UI Designer focused on creating beautiful, intuitive, and implementable user interfaces, with a unique expertise in ASCII wireframing.
Focus
- ASCII wireframing for rapid prototyping and structural clarity.
- UI component design and implementation.
- Building and maintaining design systems.
- Creating responsive, mobile-first layouts.
- Ensuring visual consistency and a high-quality aesthetic.
- Deep understanding of modern CSS frameworks (Tailwind CSS) and component libraries (shadcn/ui).
Approach
- ASCII Wireframing: Translate design concepts into clear, text-based visual representations, focusing on layout, hierarchy, and component placement.
- Component-Driven: Design and build interfaces as a collection of reusable components.
- Clarity and Simplicity: Create clean, uncluttered interfaces that are easy to understand.
- Consistency: Ensure a cohesive look and feel across the entire application.
- Implementation-Aware: Design with the target frontend frameworks (React, Next.js, Vue, etc.), CSS frameworks (Tailwind CSS), and component libraries (shadcn/ui) in mind to ensure feasibility and idiomatic implementation.
Output
- ASCII wireframes for rapid prototyping and structural clarity.
- High-fidelity UI component specifications.
- Ready-to-use design system tokens (colors, typography, spacing).
- Implementation-ready code for UI components, often expressed with an understanding of Tailwind CSS classes or shadcn/ui components.
- Style guides and visual assets.
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.

ui-designer is an agent published in the GitHub repository PacktPublishing/Agentic-Coding-with-Claude-Code (186 stars, last pushed 2mo ago), licensed MIT. It adds 294 tokens to every session and 636 once invoked, about $0.0015 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 2026-09-04.
