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 | $0.00041 | $0.00774 |
| Opus 5.5 | $0.00016 | $0.00310 |
| Sonnet 5.5 | $0.00008 | $0.00155 |
| Haiku 4.5 | $0.00004 | $0.00077 |
Grade A, and why
omd:add-reference 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 12d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
omd:add-reference — Core v2 catalog cutover gate
Status: CORE_V2_CATALOG_WRITE_BLOCKED.
Scope, narrowed by owner decision 2026-09-16. This gate blocks writes that
create a new legacy reference or a new Core catalog package. It does not
block refreshing evidence on an existing reference — verification_v2,
.verification.md, tokens.components state values, ## Proof — because that
produces no Core package and adds no migration debt; the file stays legacy and
stays in the same queue. Creating a reference, adding a brand, restoring a legacy
YAML marker, emitting retired section output, placeholder sentinels, or hand-editing
generated counts and mirrors all remain refused. Full rationale and the two expiry
conditions: .claude/skills/omd-add-reference/SKILL.md.
This repository still reads the 440 historical reference files through the
legacy frontmatter adapter. That makes them valid migration inputs, but it does
not authorize a new legacy writer. Do not create, update, backfill, or sync a
web/references/<id>/DESIGN.md from this skill.
When invoked:
- Inspect only. Do not write a reference, token block, generated catalog, or public count.
- Explain that project/user-facing DESIGN.md is already single-write Core v2, while reference authoring is paused until the catalog has a graph-backed metadata/evidence package and Core projection compiler.
- If research is still useful, save nothing to the catalog. Return a concise proposed source list and the intended reference id in chat only.
- Resume writes only after all of these exist and pass together:
- Core v2 reference metadata/evidence sidecar schema;
- registry, quality, AST, token, and verification readers for that schema;
- deterministic graph → portable DESIGN.md projection;
- legacy dual-read and Core single-write tests;
- migration report with
dropped_segments=0and unknown facts absent.
Never work around this gate by restoring a legacy YAML marker, numbered 13/15/16 sections, placeholder sentinels, or a second authoritative Markdown dialect.
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.

omd:add-reference is a skill published in the GitHub repository kwakseongjae/oh-my-design (549 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 774 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

dembrandt
A TypeScript command-line tool that renders a web page with Playwright and examines its actual styles. It turns colours, typography, spacing, borders, shadows, animation curves, components, and breakpoints into structured design tokens.
extract-design
Extract the full design language from any website URL. Produces 8 output files including AI-optimized markdown, visual HTML preview, Tailwind config, React theme, shadcn/ui theme, Figma variables, W3C design tokens, and CSS variables. Also runs WCAG accessibility scoring. Use when user says 'extract design', 'get…
designlang-tokens
Use when styling UI for cal.com — references the extracted design system tokens instead of inventing colors, spacing, or typography.
docs-crawler
Crawl an entire documentation or design-system website into one LLM-ready Markdown corpus. Discovers every page from the site's sitemap.xml (with a same-origin link-following fallback when there is no sitemap), extracts each page's main content as clean Markdown, downloads each page's images (and inline base64 images)…

Apply a Korean brand's published DESIGN.md from the ko-design-md catalog (getdesign.kr) — colors, typography, spacing, radius, components, do's & don'ts — to the UI you are building in the CURRENT project. Use this skill whenever the user wants UI built or restyled in the style of a catalogued Korean service — "토스…
brandmd
Extract a website's design system into a DESIGN.md file. Use when starting a new frontend project, rebuilding a site, or when the user wants AI-generated UI to match an existing brand.
