What is design-md-creator?

A skill that creates a DESIGN.md file, a written design system for a brand, product, or project. The document describes visual style, colors, typography, layouts, components, responsive behavior, and guidance for other agents.

Use it to document or generate a design system with visual rules, component guidance, breakpoints, accessibility-related choices, and an agent prompt guide.

It gives developers and agents a shared description of how an interface should look and behave.

Token cost

What it costs to keep this loaded

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	$0.00092	$0.01411
Opus 5	$0.00046	$0.00705
Sonnet 5	$0.00018	$0.00282
Haiku 4.5	$0.00009	$0.00141

Security

Grade A, and why

design-md-creator 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 10d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DESIGN.md Creator

Your task: produce a complete, spec-compliant DESIGN.md for $ARGUMENTS.

Reference files (read these first)

Before writing anything, read:

DESIGN_MD_SPEC.md — the full 9-section specification (field schemas, table formats, naming conventions, quality tiers)
examples/stripe-DESIGN.md — a full-tier reference showing expected depth, tone, and formatting

Both files are in the same directory as this skill file.

Workflow

Step 1 — Load the spec

Read DESIGN_MD_SPEC.md. Internalize:

The exact 9 section names and their order
Table schemas for typography, elevation, and breakpoints
The color entry format: - **Name** (\#hex`): role description`
Required prose elements: Key Characteristics bullets, Shadow Philosophy paragraph
The 13 authoring rules in §9 of the spec

Step 2 — Load the example

Read examples/stripe-DESIGN.md. Note:

How Section 1 opens with atmospheric prose before the Key Characteristics list
How Section 3's typography table is structured (Role / Font / Size / Weight / Line Height / Letter Spacing / Notes)
How Section 4 uses **Bold inline headers** (not ####) for component variants
How Section 6's elevation table + Shadow Philosophy paragraph work together
How Section 9's Example Component Prompts are formatted as quoted, specific, technical prompt strings
The overall depth: ~320 lines, all subsections present, concrete values throughout

Step 3 — Research the brand

For the brand $ARGUMENTS, gather enough context to write specific, accurate values:

If it's a well-known brand: use your training knowledge of their visual identity
If you need to verify: use WebSearch or WebFetch to inspect their website
Target: real hex codes, real font names, real spacing values — never generic placeholders

Key questions to answer before writing:

What is the primary background color? (near-black, white, off-white, branded?)
What is the primary accent / CTA color?
What font(s) do they use? (proprietary, Google Fonts, system?)
What is the typographic weight signature? (light = 300, bold = 700-900, mixed?)
What is their border-radius philosophy? (sharp = 0-4px, rounded = 8-16px, pill = 9999px?)
What is their elevation approach? (shadows, border-opacity, flat?)
What makes their design unmistakably them? (color combo, type treatment, interaction pattern?)

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.

Changes

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.
