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 | $0.00016 | $0.05401 |
| Opus 5.5 | $0.00006 | $0.02160 |
| Sonnet 5.5 | $0.00003 | $0.01080 |
| Haiku 4.5 | $0.00002 | $0.00540 |
Grade A, and why
claude-design 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 1mo 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
100% identical to claude-design — 0 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.
How it starts
The opening of the file, as written. The whole thing — 651 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Design for CLI/API Agents
Use this skill when the user asks for design work that would normally fit Claude Design, but the agent is running in a CLI/API environment instead of the hosted Claude Design web UI.
The goal is to preserve Claude Design's useful design behavior and taste while removing hosted-tool plumbing that does not exist in normal agent environments.
Before starting, check for other web-design skills like popular-web-designs (ready-to-paste design systems for Stripe, Linear, Vercel, Notion, etc.) and design-md (Google's DESIGN.md token spec format). If the user wants a known brand's look, load popular-web-designs alongside this one and let it supply the visual vocabulary. If the deliverable is a token spec file rather than a rendered artifact, use design-md instead. Full decision table below.
When To Use This Skill vs popular-web-designs vs design-md
Hermes has three design-related skills under skills/creative/. They do different jobs — load the right one (or combine them):
| Skill | What it gives you | Use when the user wants... |
|---|---|---|
| claude-design (this one) | Design process and taste — how to scope a brief, gather context, produce variants, verify a local HTML artifact, avoid AI-design slop | a from-scratch designed artifact (landing page, prototype, deck, component lab, motion study) with no specific brand or token system dictated |
| popular-web-designs | 54 ready-to-paste design systems — exact colors, typography, components, CSS values for sites like Stripe, Linear, Vercel, Notion, Airbnb | "make it look like Stripe / Linear / Vercel", a page styled after a known brand, or a visual starting point pulled from a real product |
| design-md | Google's DESIGN.md spec format — author/validate/diff/export design-token files, WCAG contrast checking, Tailwind/DTCG export | a formal, persistent, machine-readable design-system spec file (tokens + rationale) that lives in a repo and gets consumed by agents over time |
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 is a skill published in the GitHub repository cyborg-garden/hermes-agent-mt (14 stars, last pushed 3d ago), licensed MIT. It adds 16 tokens to every session and 5,401 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to claude-design, differing in 0 lines, and is treated as a copy.
