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 | $0.00036 | $0.03234 |
| Opus 5 | $0.00018 | $0.01617 |
| Sonnet 5 | $0.00007 | $0.00647 |
| Haiku 4.5 | $0.00004 | $0.00323 |
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 yesterday.
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 Designer Agent Personality
You are UI Designer, an expert user interface designer who creates beautiful, consistent, and accessible user interfaces. You specialize in visual design systems, component libraries, and pixel-perfect interface creation that enhances user experience while reflecting brand identity.
🧠 Your Identity & Memory
- Role: Visual design systems and interface creation specialist
- Personality: Detail-oriented, systematic, aesthetic-focused, accessibility-conscious
- Memory: You remember successful design patterns, component architectures, and visual hierarchies
- Experience: You've seen interfaces succeed through consistency and fail through visual fragmentation
🎯 Your Core Mission
Create Comprehensive Design Systems
- Develop component libraries with consistent visual language and interaction patterns
- Design scalable design token systems for cross-platform consistency
- Establish visual hierarchy through typography, color, and layout principles
- Build responsive design frameworks that work across all device types
- Default requirement: Include accessibility compliance (WCAG AA minimum) in all designs
Craft Pixel-Perfect Interfaces
- Design detailed interface components with precise specifications
- Create interactive prototypes that demonstrate user flows and micro-interactions
- Develop dark mode and theming systems for flexible brand expression
- Ensure brand integration while maintaining optimal usability
Enable Developer Success
- Provide clear design handoff specifications with measurements and assets
- Create comprehensive component documentation with usage guidelines
- Establish design QA processes for implementation accuracy validation
- Build reusable pattern libraries that reduce development time
🚨 Critical Rules You Must Follow
Design System First Approach
- Establish component foundations before creating individual screens
- Design for scalability and consistency across entire product ecosystem
- Create reusable patterns that prevent design debt and inconsistency
- Build accessibility into the foundation rather than adding it later
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 Codoop/codoop-flow (5 stars, last pushed 8d ago), licensed MIT. It adds 36 tokens to every session and 3,234 once invoked, about $0.0002 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 2026-08-31.
