yohaku-design

The Yohaku design system: static tokens, component catalog, and section snippets for the Yohaku personal blog. Adapts the Kami constraint-system shape to a webapp context.

If unsure, ask one short question instead of guessing.

Step 2 · Produce

New mockup

  1. Copy templates/scaffold.html to docs/superpowers/plans/<topic>-mockup.html (or wherever the user wants).
  2. Pick relevant pieces from templates/snippets/ (hero, list-card, modal, sheet, form, code-block, stat-grid, comment-thread). Copy and adapt.
  3. Use only token classes / vars listed in CHEATSHEET.md. No raw hex except inside <style> blocks where contract applies.
  4. Open the file in a browser to verify before declaring done.

New React component

  1. First check references/components.md and apps/web/src/components/ui/ to confirm the primitive does not already exist. Reuse beats reinvent.
  2. If a new ui/ entry is needed, follow the patterns in components.md (file structure, exports, Tailwind variants).
  3. Use only the tokens listed in CHEATSHEET.md. Never reach for text-neutral-50…950.
  4. Run pnpm --filter @yohaku/web lint on changed files only (do not lint the whole project).

Handoff

  1. Open the mockup HTML and references/mockup-to-react.md side by side.
  2. Walk the mapping table top-to-bottom: every HTML class / pattern has a target React component or Tailwind class.
  3. Replace structure first, styling second. Do not introduce new tokens during handoff.
  4. Run pnpm --filter @yohaku/web lint on the changed files.

Token audit

  1. Read references/anti-patterns.md.
  2. Scan the target file for: text-neutral-50/100/200/.../950, raw hex literals, n-5 used as text, hardcoded font-family, synthetic font-weight: bold on Chinese text.
  3. Report a punch list with line numbers and proposed replacements.

Step 3 · Verify

pnpm --filter @yohaku/design-system check

Lints token drift between the cheatsheet and src/tokens.css, plus forbidden patterns in templates/. Run before committing changes inside packages/design-system/.

When NOT to use this skill

  • Editing application logic, routes, queries, hooks — this skill is design-only.
  • Producing PDF / slides / marketing pages — Yohaku is a webapp, use Kami for static documents.
  • Restyling @haklex/* packages — those have their own rich-style-token system.
  • Modifying apps/web/src/styles/yohaku.css runtime injection — that is application owned, not design contract.

Languages

This skill, the cheatsheet, and references are English. The web app and its content are Chinese-first. Do not translate the contract docs.
