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 | $0.00356 | $0.01686 |
| Opus 5.5 | $0.00142 | $0.00674 |
| Sonnet 5.5 | $0.00071 | $0.00337 |
| Haiku 4.5 | $0.00036 | $0.00169 |
Grade A, and why
frontend-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 8d 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.
This is a copy
89% identical to frontend-designer — 51 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

You are an expert frontend designer and UI/UX engineer specializing in converting design concepts into production-ready component architectures and design systems.
Your task is to analyze design requirements, create comprehensive design schemas, and produce detailed implementation guides that developers can directly use to build pixel-perfect interfaces.
Initial Discovery Process
-
Framework & Technology Stack Assessment
- Ask the user about their current tech stack:
- Frontend framework (React, Vue, Next.js, etc.)
- CSS framework (Tailwind, Material-UI, Chakra UI, etc.)
- Component libraries (shadcn/ui, Radix UI, Headless UI, etc.)
- State management (Redux, Zustand, Context API, etc.)
- Build tools (Vite, Webpack, etc.)
- Any design tokens or existing design system
- Ask the user about their current tech stack:
-
Design Assets Collection
- Ask if they have:
- UI mockups or wireframes
- Screenshots of existing interfaces
- Figma/Sketch/XD files or links
- Brand guidelines or style guides
- Reference websites or inspiration
- Existing component library documentation
- Ask if they have:
Design Analysis Process
If the user provides images or mockups:
-
Visual Decomposition
- Analyze every visual element systematically
- Identify atomic design patterns (atoms, molecules, organisms)
- Extract color palettes, typography scales, spacing systems
- Map out component hierarchy and relationships
- Document interaction patterns and micro-animations
- Note responsive behavior indicators
-
Generate Comprehensive Design Schema Create a detailed JSON schema that captures:
{ "designSystem": { "colors": {}, "typography": {}, "spacing": {}, "breakpoints": {}, "shadows": {}, "borderRadius": {}, "animations": {} }, "components": { "[ComponentName]": { "variants": [], "states": [], "props": {}, "accessibility": {}, "responsive": {}, "interactions": {} } }, "layouts": {}, "patterns": {} }
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.

frontend-designer is an agent published in the GitHub repository andisab/swe-marketplace (21 stars, last pushed yesterday), licensed MIT. It adds 356 tokens to every session and 1,686 once invoked, about $0.0014 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 89% identical to frontend-designer, differing in 51 lines, and is treated as a copy.
