Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

- NVIDIA SkillSpector warn
SkillSpector: 4 findings, up to high
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00088 | $0.05933 |
| Opus 5.5 | $0.00035 | $0.02373 |
| Sonnet 5.5 | $0.00018 | $0.01187 |
| Haiku 4.5 | $0.00009 | $0.00593 |
Grade A, and why
drydock 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 25d 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.
How it starts
The opening of the file, as written. The whole thing — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Drydock
Lay the keel of the shipyard: one repo, one shared harness, every contributor inherits it. This skill seeds exactly two faces (CLAUDE.md and GLOSSARY.md), with a read-once migration for recognizable legacy glossary CONTEXT.md files, and defines the first-use moment when every other surface appears. It wires the flows that fill them (launch writes GLOSSARY.md vocabulary and decision records; launch C5 sediment and reviews sediment standards) and reports what was seeded, what is deferred and why, and what was skipped on purpose.
The four pillars and where they physically live:
| Pillar | Surfaces |
|---|---|
| Context (shared background) | GLOSSARY.md (glossary) + docs/business/ + docs/adr/ + OMC wiki |
| Rules (boundaries) | CLAUDE.md (thin entry: conventions, principles, index) + docs/standards/ |
| Tools (composable capability) | .omc/skills/ + .mcp.json + scripts/ |
| Standards (the classification society) | design-system/ (tokens, components, patterns) + docs/standards/ |
Metaphor map: the shipyard is the shared facility; the classification society (docs/standards/ + design-system/) sets the rules a ship must pass to be seaworthy; drydock lays the keel; launch ships it.
When to Use
- starting a repo that humans and agents will both build on
- a repo where knowledge lives in people's heads and chat history instead of files
- onboarding: a new teammate or agent should inherit context by reading, not by asking
When Not to Use
- throwaway prototypes with no collaborators
- a repo already running this harness (use
--checkinstead)
Workflow
1. Detect (never clobber)
Inventory what exists before writing anything:
CLAUDE.mdpresent?AGENTS.mdpresent? (rule: if either exists, extend it in place; create the missing one as a one-line pointer to the other; never create both fresh)GLOSSARY.md(or a recognizable legacy glossaryCONTEXT.md),docs/adr/,docs/standards/,docs/business/,design-system/,.omc/skills/,.mcp.json,scripts/,.gitattributes— which exist (adopted — their integrity is audited), which are absent (not adopted — each gets its first-use trigger below, never a speculative creation)?- OMC installed? — only worth checking when running inside an OMC session; outside one, skip this check silently (the harness works with or without OMC)
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.

drydock is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (40,625 stars, last pushed yesterday), licensed MIT. It adds 88 tokens to every session and 5,933 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-02.
