oh-my-design: Skill for Claude Code

.claude/skills/omd-learn/SKILL.md

omd:learn is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 96 tokens per session (2,808 once invoked), scanned A, original, MIT.

A process that turns pending entries from `.omd/preferences.md` into the project's `DESIGN.md`, its design-system guide, through the underlying system graph.

In plain words
What is it for?
Use it when asking to apply or fold preferences into the design system. It reviews pending entries by scope, asks for confirmation, regenerates `DESIGN.md`, and marks applied entries as complete.
Why use it?
It gathers scattered design corrections into the main project rules instead of leaving them as temporary notes.

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

omd:learn 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 11d 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.

omd:learn — Preference Fold into Core v2

.omd/preferences.md에 누적된 status: pending 교정사항을 Core v2 System Graph에 반영하고, 그 graph에서 중립적인 root DESIGN.md를 재생성한 뒤 반영된 엔트리의 상태를 applied로 플립한다. DESIGN.md를 직접 섹션 편집하는 스킬이 아니다.

Phase 1 — 검토

Read .omd/preferences.md → frontmatter + 엔트리들 파싱:

  • 엔트리 분리: ## heading 기준 split
  • 각 엔트리의 omd-meta 코드블록에서 id, scope, status 추출
  • status: pending만 필터

scope별로 그룹화해서 사용자에게 요약:

components.button (3 pending):
  - CTAs never uppercase (pref_xxx, pref_yyy)
  - primary fill should be brand-500 not 600 (pref_zzz)

spacing (1 pending):
  - 8pt grid, not 4pt (pref_aaa)

엔트리당 한 줄이 아니라 scope당 2-3줄로 의도 정리.

Phase 2 — 사용자 확인

"이 교정들을 디자인 시스템에 반영할까요?" 묻기. 동의 → Phase 3.

거부 → 어떤 scope를 reject할지 묻고 Phase 4 reject 분기로.

Phase 3 — Core v2 graph-first 적용

3.1 포맷·권위 게이트

  1. root DESIGN.md를 읽고 .omd/system/manifest.json + graph.json의 존재와 exact hash binding을 확인한다.
  2. 유효한 profile: portable-core Bound Core v2이면 graph.json이 canonical이다. migration-candidate는 source DESIGN.md authority를 유지한다. visible Markdown의 heading이나 표를 직접 편집하지 않는다.
  3. Portable-only Core, legacy 13/15/16-section, unmarked 문서이면 설치된 provider-free migrator로 별도 fresh staging directory에 migration을 실행한다. public CLI가 있으면 omd design-md migrate DESIGN.md --out-dir <fresh-migration-dir>를 사용한다. helper가 없으면 직접 편집으로 우회하지 말고 stale install을 보고한다.
  4. report의 dropped_segments=0, synthetic_product_values_added=0, projection_roundtrip_equal=true, source_reconstruction_equal=true, opaque_extension_preserved=true가 모두 확인되어야 계속한다. unsupported_claims_review_required=true이므로 staging 결과는 migration-candidate인 non-authoritative observation이다. 곧바로 canonical authority로 승격하지 않는다. 이해하지 못한 원본은 extensions["dev.oh-my-design.migration"]에 보존한다.
  5. staging에서만 수정하고 원본 bytes, source hash, migration report를 content-addressed rollback artifact로 남긴다. 실패 시 root 파일을 건드리지 않는다.

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.
