oh-my-design: Skill for Claude Code

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

omd:sync is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 98 tokens per session (1,877 once invoked), scanned A, original, MIT.

A maintenance workflow that copies the project’s design rules from DESIGN.md into instruction files used by Claude Code, Codex, and Cursor. It updates only the managed sections where appropriate.

In plain words
What is it for?
Use it after changing DESIGN.md, or to check and update CLAUDE.md, AGENTS.md, and the Cursor design-rules file.
Why use it?
It keeps coding agents aligned with the current design rules and reduces drift between the source document and their project instructions.

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is kwakseongjae/oh-my-design's own configuration. It tells Claude Code how to work on oh-my-design itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything oh-my-design configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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:sync 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.

CLAUDE.md body

# Design System (oh-my-design)

Read the standalone design contract at **@./DESIGN.md** before any UI,
styling, microcopy, or motion work. When a valid adopted Core v2
`.omd/system/manifest.json` declares `profile: portable-core` and binds exact
graph/projection hashes, the System Graph is machine authority and DESIGN.md is
its standalone projection. A migration candidate is never adopted authority.

Preference log (pending corrections): @./.omd/preferences.md

Precedence: pending explicit preference corrections > adopted Bound System
graph/standalone DESIGN.md > your defaults. Fold pending corrections into the
graph and regenerate the projection before clearing them.

AGENTS.md body

## Design System (oh-my-design)

**Before any UI, styling, copy, or motion change, open and read `./DESIGN.md` in full.** It is the standalone design contract. If an exact valid adopted Core v2 manifest exists, its hash-bound System Graph is machine authority and DESIGN.md is the projection. A migration candidate remains non-authoritative.

If present, read `./.omd/preferences.md` — pending explicit corrections override the current contract until atomically folded into the graph/projection. Apply them and flag conflicts.

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.
