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 | $0.00138 | $0.01427 |
| Opus 5.5 | $0.00055 | $0.00571 |
| Sonnet 5.5 | $0.00028 | $0.00285 |
| Haiku 4.5 | $0.00014 | $0.00143 |
Grade A, and why
claude-design-md-generator 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 2mo 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md Generator
For users designing UI screens in Claude Design — dashboards, apps, admin tools, SaaS products, internal tools, any product surface.
Produces a CLAUDE.md file, ~60–100 lines, that Claude Design auto-loads at the root of every chat in the project. Ask 5 questions, compose, present.
This skill is scoped to UI screen design. If the user is building something else (marketing sites, editorial/lifestyle brand sites, long-form content surfaces), still produce a CLAUDE.md — but flag that the shape is optimised for product UI and some rules may need adjusting.
The interview
Ask one question at a time, conversationally. Don't dump the full list. Adapt based on prior answers.
Q1. Name and one-sentence description. "What's the project called, and what is it in one sentence?"
Q2. Codebase and design system state. "Is there a linked codebase? A design system? Or is this design-only for now?" If linked, ask the stack in one line.
Q3. Aesthetic in one concrete sentence. "Describe the feel in one or two concrete sentences. Avoid adjectives like 'modern' or 'clean' — name measurable things (density, font treatment, surface style, palette direction)." If they only give adjectives, push back once: "Can you give me one concrete constraint? E.g., 'dense tables with tabular figures, 1px borders instead of fills' or 'lots of whitespace, one accent colour, 4pt grid'."
Q4. Tokens. Ask only if no linked design system. Request: background, foreground, one accent (with scope of use — e.g., "CTAs only"), headline font, body font. 5 values, not a full palette. For product UI, also ask if there's a mono font for numbers, IDs, and code.
Q5. Top three don'ts. "What are three things Claude Design should never do on this project?" If they don't know, suggest defaults and let them confirm or adjust. Product UI defaults:
- Never invent hex values outside the token set.
- Never use drop shadows (use 1px borders instead).
- Never Title Case button labels — sentence case only.
- Never use emoji in UI chrome.
- Never use more than 2 font weights on a single screen.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-design-md-generator is a skill published in the GitHub repository eddie199/claude-design-md (3 stars, last pushed 6mo ago), licensed MIT. It adds 138 tokens to every session and 1,427 once invoked, about $0.0006 per session on Opus 5.5. 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.
