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 | $0.00014 | $0.01831 |
| Opus 5 | $0.00007 | $0.00915 |
| Sonnet 5 | $0.00003 | $0.00366 |
| Haiku 4.5 | $0.00001 | $0.00183 |
Grade A, and why
design-md 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
91% identical to design-md — 18 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 — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DESIGN.md Skill
DESIGN.md is Google's open spec (Apache-2.0, google-labs-code/design.md) for
describing a visual identity to coding agents. One file combines:
- YAML front matter — machine-readable design tokens (normative values)
- Markdown body — human-readable rationale, organized into canonical sections
Tokens give exact values. Prose tells agents why those values exist and how to
apply them. The CLI (npx @google/design.md) lints structure + WCAG contrast,
diffs versions for regressions, and exports to Tailwind or W3C DTCG JSON.
When to use this skill
- User asks for a DESIGN.md file, design tokens, or a design system spec
- User wants consistent UI/brand across multiple projects or tools
- User pastes an existing DESIGN.md and asks to lint, diff, export, or extend it
- User asks to port a style guide into a format agents can consume
- User wants contrast / WCAG accessibility validation on their color palette
For purely visual inspiration or layout examples, use popular-web-designs
instead. For process and taste when designing a one-off HTML artifact
from scratch (prototype, deck, landing page, component lab), use
claude-design. This skill is for the formal spec file itself.

## Overview
Architectural Minimalism meets Journalistic Gravitas...
## Colors
- **Primary (#1A1C1E):** Deep ink for headlines and core text.
- **Tertiary (#B8422E):** "Boston Clay" — the sole driver for interaction.
## Typography
Public Sans for everything except small all-caps labels...
## Components
`button-primary` is the only high-emphasis action on a page...
What ships with it
1 file 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.
- 8d ago First seen · 199 lines · 14 tokens per session scan A 6338f959dd6a
design-md is a skill published in the GitHub repository nativ3ai/hermes-agent-camel (196 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 1,831 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to design-md, differing in 18 lines, and is treated as a copy.
