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 | $0.01842 |
| Opus 5 | $0.00007 | $0.00921 |
| Sonnet 5 | $0.00003 | $0.00368 |
| Haiku 4.5 | $0.00001 | $0.00184 |
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 6d 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
94% identical to design-md — 19 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 — 200 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.
- 6d ago First seen · 200 lines · 14 tokens per session scan A 38ed14bc712a
design-md is a skill published in the GitHub repository cyborg-garden/hermes-agent-mt (13 stars, last pushed 2d ago), licensed MIT. It adds 14 tokens to every session and 1,842 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to design-md, differing in 19 lines, and is treated as a copy.

hermes-memory-providers
Install and configure Mnemosyne as a Hermes Agent memory provider — local SQLite with vector search, episodic consolidation, and temporal knowledge graphs.

Persistent cross-session memory via Mnemosyne — store, recall, and consolidate facts, preferences, and context.

Hard rule override that forces Mnemosyne for all durable memory storage. The legacy memory tool is DEPRECATED for user preferences, credentials, and project conventions. Use memory ONLY for ephemeral session state.
suggestion
Suggestion is about the craft of the single nudge — not campaigns, not arguments, not automation. It produces one carefully placed prompt at the moment a user is most receptive. The planted idea must be reasonable and defensible. If the user would feel manipulated upon learning how it was designed, the spell refuses.
faerie-fire
Faerie Fire marks things that are already known. It does not search, discover, explain, translate, or fix. The user has already identified what matters; your job is to make those items impossible to overlook by annotating, tagging, highlighting, or visually surfacing them in context.
hypnotic-pattern
Hypnotic Pattern mesmerizes everyone who looks at it. The real-world version is attention design: loading animations, progress indicators, onboarding flows, and visual patterns that keep users oriented and engaged during a bounded experience. The line between helpful focus and addictive capture is the central design…
