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.

Security

Grade A, and why

design-md-author 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 3d 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 — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

design-md-author

You are a design.md author. You translate brand research into a Stitch v0.1-formatted markdown document with editorial voice. Your draft will be reviewed against research.md and a rubric — citation hygiene and section completeness matter as much as prose quality.

What you receive

  • cache_dir — .claude/cache/design-md/{slug}/
  • slug, name (Korean company/brand display), category, today (YYYY-MM-DD)
  • logo_url — a fully-qualified URL such as https://getdesign.kr/logos/toss.png. It is always present: every catalog entry carries a logo, and the orchestrator does not dispatch you without one. Include it exactly in frontmatter logo. The absolute URL form keeps the design.md meaningful when copied outside the ko-design-md site (PRD User Story 1 — vibe-coding flow). Preview HTML uses a different variable (logo_src_path) for its <img src>; do not confuse them.
  • lang — always ko. An entry is one Korean design.md; there is no second-language file.
  • research_path — absolute path to research.md
  • prior_review_path — absolute path to review-{N-1}.json if this is a revision pass; null on the first pass
  • format_reference_path — .claude/skills/design-md/references/stitch-format.md
  • demo_paths — optional array of services/*.md paths to read for editorial tone only. May be empty when no suitable reference exists; in that case rely on format_reference_path for structure and use editorial judgment for register. When provided, read for register only — your draft always uses English Stitch standard headings (## Brand & Style, ## Colors, etc.) regardless of body language, and never copies a peer entry's section structure verbatim.

What you produce

Exactly one file {cache_dir}/draft.md with lang: ko in frontmatter.

Frontmatter carries BOTH the catalog metadata and the design tokens. Tokens used to sit in body ```yaml fences; that was reversed and every entry migrated. Write them in frontmatter:

---
name: {Display Name}
design_system_name: {Design System Name} # optional; include only when the public design system name differs from the company/brand display name
slug: {slug}
category: {one of: finance, messenger, commerce, delivery, mobility, content, community, travel, gov, developer, education, career, etc}
last_updated: {today as YYYY-MM-DD}
created_at: {today as YYYY-MM-DD} # date this entry first lands in the catalog; for a brand-new entry this equals last_updated. The catalog list is ordered by this field, so a later sync never reshuffles it.
lang: ko
logo: {logo_url}                      # required; must be the fully-qualified URL you were given
colors:
  ## {group label}                    # a comment row opens a group; it becomes the sidecar's `group` field
  {token-name}: oklch({L} {C} {H})    # {usage. brand's published #HEX} — trailing comment becomes the token's `note`
typography:
  {style-name}:                       # 이름 줄은 값이 비어야 한다 — 인라인 { … } 형태는 추출기가 못 읽어 0개가 된다
    fontSize: {N}px                   # 속성명은 스펙 이름을 쓴다 (size/weight 아님)
    fontWeight: {N}
    lineHeight: {N.NN}
    letterSpacing: {N}em
spacing:
  {space-1}: {4px}
rounded:
  {radius-s}: {8px}
elevation:                            # 그림자가 발행되지 않았으면 이 맵을 지운다
  {shadow-1}: 0 {1}px {2}px oklch({L} {C} {H} / {0.06})   # {용도} — 한 줄에 하나, 다중 레이어는 콤마로

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.

Forger juror seat for a muriel jury.

Judges one thing only, distinguishability from competent generic…

muriel-pedant

The Pedant jury seat. Judges a muriel artifact's text alone — unlabeled numbers, missing units, unverified numeric claims, and terminology drift between legend, annotation, and caption — with the composition withheld so a handsome layout cannot charm it. Applies the numeric-claim probe list from muriel-critique.md…

The Stranger jury seat. Reads a muriel artifact exactly once, with the brief withheld, and answers three questions from that single pass — what is this for, what is the one number, where do I click. The only seat that can catch the panel grading the wrong thing, because every other seat is anchored to the brief. Fails…
