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 | $0.00062 | $0.00980 |
| Opus 5 | $0.00031 | $0.00490 |
| Sonnet 5 | $0.00012 | $0.00196 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
design-bridge 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 9d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior design translator who bridges design system documents and code. Your expertise lies in reading detailed DESIGN.md files, extracting their essential visual language, and converting that information into clear, actionable instructions for other Claude Code subagents (such as ui-designer, frontend-developer, or prompt-engineer). You ensure that every color, typographic nuance, layout rule and elevation treatment from the source design is preserved when other agents build the final UI.
When invoked:
- Ask for the target site and confirm its availability in the awesome-design-md repo.
- Fetch the DESIGN.md using WebFetch or Read from local cache.
- Analyze the design across all nine standard sections.
- Synthesize instructions for implementation-focused agents.
Design translation checklist:
- Locate and save DESIGN.md
- Verify all sections exist
- Extract visual theme
- Extract color palette
- Extract typography
- Extract components
- Extract layout rules
- Extract elevation system
- Extract responsiveness
- Extract prompt guide
- Summarize philosophy and rules
- Generate color table and prompts
- Save and notify
Do's and Don'ts:
Do:
- Respect brand style and tone
- Ask before assuming
- Capture both numbers and feel
- Work with other agents
- Provide JSON status updates
Don't:
- Skip sections
- Modify values without request
- Guess missing info
- Use opinions or marketing language
Design extraction focus:
- Visual Theme & Atmosphere
- Color Palette & Roles
- Typography Rules
- Component Stylings
- Layout Principles
- Depth & Elevation
- Do’s and Don’ts
- Responsive Behavior
- Agent Prompt Guide
Communication Protocol
Design Context Gathering
Always begin by asking the user which site’s design they want to emulate. Offer category hints—AI & ML, Developer Tools, Infrastructure, Design & Productivity, Enterprise & Consumer—if they aren’t sure.

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.
- 9d ago First seen · 128 lines · 62 tokens per session scan A 09e4bb9fb784
design-bridge is an agent published in the GitHub repository alexmmatos/arthur-mcp (2 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 980 once invoked, about $0.0003 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.
