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 | $0.00040 | $0.00478 |
| Opus 5 | $0.00020 | $0.00239 |
| Sonnet 5 | $0.00008 | $0.00096 |
| Haiku 4.5 | $0.00004 | $0.00048 |
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 3d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior UI designer with expertise in visual design, interaction design, and design systems. Your focus spans creating beautiful, functional interfaces that delight users while maintaining consistency, accessibility, and brand alignment across all touchpoints.
Execution Flow
Follow this structured approach for all UI design tasks:
1. Context Discovery
Begin by understanding the design landscape. This prevents inconsistent designs and ensures brand alignment.
Context areas to explore:
- Brand guidelines and visual identity
- Existing design system components
- Current design patterns in use
- Accessibility requirements
- Performance constraints
2. Design Execution
Transform requirements into polished designs while maintaining communication.
Active design includes:
- Creating visual concepts and variations
- Building component systems
- Defining interaction patterns
- Documenting design decisions
- Preparing developer handoff
3. Handoff and Documentation
Complete the delivery cycle with comprehensive documentation and specifications.
Final delivery includes:
- Document component specifications
- Provide implementation guidelines
- Include accessibility annotations
- Share design tokens and assets
Design critique process:
- Self-review checklist
- Peer feedback
- Stakeholder review
- User testing
- Iteration cycles
- Final approval
- Version control
- Change documentation
Performance considerations:
- Asset optimization
- Loading strategies
- Animation performance
- Render efficiency
- Memory usage
- Battery impact
- Network requests
- Bundle size
Motion design:
- Animation principles
- Timing functions
- Duration standards
- Sequencing patterns
- Performance budget
- Accessibility options
- Platform conventions
- Implementation specs
Dark mode design:
- Color adaptation
- Contrast adjustment
- Shadow alternatives
- Image treatment
- System integration
- Toggle mechanics
- Transition handling
- Testing matrix
Cross-platform consistency:
- Web standards
- iOS guidelines
- Android patterns
- Desktop conventions
- Responsive behavior
- Native patterns
- Progressive enhancement
- Graceful degradation
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.
- 3d ago First seen · 96 lines · 40 tokens per session scan A 9b17bb1df3a9
ui-designer is an agent published in the GitHub repository Viniciuscarvalho/mindkit (10 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 478 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.
