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

kernel-chat-design 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 5d ago.

The scan reads SKILL.md. This mod also ships 15 executable files (_ds_bundle.js, build-gallery.mjs, components/editorial/Banner.d.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Read the readme.md file within this skill, and explore the other available files.

If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand.

Quick start

  • Entry point: styles.css — link it (or its @imported tokens/ + primitives/editorial.css) to get every token, the two webfonts, and the pop-* editorial utility classes.
  • The register — warm paper stocks, tomato (#E24E1B) as the only spot colour, EB Garamond display + Courier Prime meta, bilingual JP/EN, bracketed kickers, numbered catalogs, issue monuments. Type-first, square, hairline rules. The terminal "quiet utility core" carries a hard tomato block shadow.
  • Components (React): components/editorial/ — Kicker, Banner, Monument, CatalogRow, Terminal. Each has a .prompt.md with usage; mount from the compiled bundle namespace.
  • Whole surface: copy ui_kits/magazine/ (cover → contents → essay spread → colophon) and adapt.
  • Icons: the one system glyph is the asterisk ★ (inline 3-line SVG); <PopIcon> editorial pictograms (1.75px stroke) for sparing accents. No emoji.

Hard rules

  1. Never name the design inspiration on any user-visible surface.
  2. Tomato is the only spot colour. (Purple #6B5B95 is the logo mark only.)
  3. EB Garamond + Courier Prime for Latin; Noto Serif JP for Japanese.
  4. Never pure #ffffff — use warm ivory/cream/butter/kraft/ledger stocks.
  5. Bilingual everywhere it fits. One system glyph (★). No emoji.
  6. Every release is an "ISSUE N · MONTH YEAR".

If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.

Files

What ships with it

60 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.
