oh-my-design: Skill for Claude Code

.agents/skills/omd-add-reference/SKILL.md

omd:add-reference is a skill for Claude Code from kwakseongjae/oh-my-design. It costs 41 tokens per session (368 once invoked), scanned A, original, MIT.

A safety gate for adding reference entries to a catalogue. It checks whether the newer Core v2 catalogue system is ready before allowing new design references.

In plain words
What is it for?
Use it to inspect whether reference writing can resume, understand the required migration checks, or receive a proposed source list without changing the catalogue.
Why use it?
It prevents new entries from being written in the older format while the catalogue still depends on historical files. This avoids creating data that later migration could mishandle.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: installed under .agents/ (shared by several agents).

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 →

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:add-reference 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.

What it actually says

omd:add-reference — Core v2 catalog cutover gate

Status: CORE_V2_CATALOG_WRITE_BLOCKED.

This repository still reads the 440 historical reference files through the legacy frontmatter adapter. That makes them valid migration inputs, but it does not authorize a new legacy writer. Do not create, update, backfill, or sync a web/references/<id>/DESIGN.md from this skill.

When invoked:

  1. Inspect only. Do not write a reference, token block, generated catalog, or public count.
  2. Explain that project/user-facing DESIGN.md is already single-write Core v2, while reference authoring is paused until the catalog has a graph-backed metadata/evidence package and Core projection compiler.
  3. If research is still useful, save nothing to the catalog. Return a concise proposed source list and the intended reference id in chat only.
  4. Resume writes only after all of these exist and pass together:
    • Core v2 reference metadata/evidence sidecar schema;
    • registry, quality, AST, token, and verification readers for that schema;
    • deterministic graph → portable DESIGN.md projection;
    • legacy dual-read and Core single-write tests;
    • migration report with dropped_segments=0 and unknown facts absent.

Never work around this gate by restoring a legacy YAML marker, numbered 13/15/16 sections, placeholder sentinels, or a second authoritative Markdown dialect.

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.
