oh-my-design: Skill for Claude Code

.agents/skills/omd/SKILL.md

omd is a skill for Claude Code, Codex from kwakseongjae/oh-my-design. It costs 73 tokens per session (793 once invoked), scanned A, original, MIT.

A compatibility router for older OmD commands. It sends existing interface work, new projects, or design-file setup to the correct current workflow.

In plain words
What is it for?
Use it when an old `omd` command is invoked and the work must be directed to `omd:apply`, `omd:autopilot`, or `omd:init`.
Why use it?
It lets older commands keep working while the project uses newer workflows and design rules. It also avoids changing the main design file itself.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is kwakseongjae/oh-my-design's own configuration. It tells Claude Code and Codex 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 →

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 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 compatibility router

ROUTER_ONLY_NO_DESIGN_MD_WRITES

This skill preserves old omd entrypoints while the active workflows live in omd:apply, omd:autopilot, and omd:init. It classifies the available design context, transfers the original request to one canonical workflow, and then stops. Do not duplicate a target workflow here.

Authority classification

Inspect these files without mutating them:

  1. A valid adopted Core v2 package has a hash-bound .omd/system/manifest.json with format: design-md-core, format_version: 2.0.0, profile: portable-core, and authority.canonical: system-graph. Only after the target workflow validates the manifest, graph, projection, and exact bidirectional hashes is .omd/system/graph.json canonical. Root DESIGN.md remains its complete, vendor-neutral portable projection.
  2. profile: migration-candidate is non-authoritative. Keep the source DESIGN.md named by its authority record canonical while the candidate is reviewed. Never use the candidate as a Bound System.
  3. If the package is absent, stale, invalid, or hash-mismatched, use root DESIGN.md independently for the rules it actually expresses. It does not require sidecars, an OmD install, or this skill to be useful. Do not claim graph authority or a conformance level that has not been validated.
  4. A legacy or unmarked root DESIGN.md remains a read-only compatibility input. If root DESIGN.md is absent, .stitch/DESIGN.md may be used only as the same read-only fallback. Apply declared rules, omit unknown values at the smallest boundary, and never silently rewrite or upgrade either file.

A stale binding invalidates graph authority, not the readable Markdown. Never promote reference observations, placeholders, or generic defaults into project facts.

Route once

  • Existing UI, component, styling, motion, microcopy, design review, or other bounded product work -> transfer the unchanged request and authority classification to omd:apply.
  • Broad from-scratch product work, a new surface with delegated decisions, or autonomous design-system-plus-implementation work -> transfer to omd:autopilot.
  • DESIGN.md bootstrap, design-system-only creation, explicit migration, refactor, or refresh without product implementation -> transfer to omd:init.
  • If the user explicitly requests guided checkpoints, transfer to omd:harness; do not convert that request into Autopilot.

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.
