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
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00018 | $0.05723 |
| Opus 5 | $0.00009 | $0.02861 |
| Sonnet 5 | $0.00004 | $0.01145 |
| Haiku 4.5 | $0.00002 | $0.00572 |
Grade A, and why
skill 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 7d 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.

The opening of the file, as written. The whole thing — 848 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Management CLI
Meta-skill for managing oh-my-claudecode skills via CLI-like commands.
Subcommands
/skill list
Show all available skills organized by scope.
Behavior:
- Scan bundled built-in skills in the plugin
skills/directory (read-only) - Scan user skills at
${CLAUDE_CONFIG_DIR:-~/.claude}/skills/omc-learned/ - Scan project skills at
.omc/skills/ - Parse YAML frontmatter for metadata
- Display in organized table format:
BUILT-IN SKILLS (bundled with oh-my-claudecode):
| Name | Description | Scope |
|-------------------|--------------------------------|----------|
| visual-verdict | Structured visual QA verdicts | built-in |
| ralph | Persistence loop | built-in |
USER SKILLS (~/.claude/skills/omc-learned/):
| Name | Triggers | Quality | Usage | Scope |
|-------------------|--------------------|---------|-------|-------|
| error-handler | fix, error | 95% | 42 | user |
| api-builder | api, endpoint | 88% | 23 | user |
PROJECT SKILLS (.omc/skills/):
| Name | Triggers | Quality | Usage | Scope |
|-------------------|--------------------|---------|-------|---------|
| test-runner | test, run | 92% | 15 | project |
Fallback: If quality/usage stats not available, show "N/A"
Built-in skill note: Built-in skills are bundled with oh-my-claudecode and are discoverable/readable, but not removed or edited through /skill remove or /skill edit.
/skill add [name]
Interactive wizard for creating a new skill.
Behavior:
- Ask for skill name (if not provided in command)
- Validate: lowercase, hyphens only, no spaces
- Ask for description
- Clear, concise one-liner
- Ask for triggers (comma-separated keywords)
- Example: "error, fix, debug"
- Ask for argument hint (optional)
- Example: " [options]"
- Ask for scope:
user→${CLAUDE_CONFIG_DIR:-~/.claude}/skills/omc-learned/<name>/SKILL.mdproject→.omc/skills/<name>/SKILL.md
- Create skill file with template:
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.

skill is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (39,083 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 5,723 once invoked, about $0.0001 per session on Opus 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 2026-09-03.

computer-use
OS-level computer use on the local X11 desktop via the cua-driver daemon: screenshots, AT-SPI element trees, background (co-work) mouse/keyboard input, and window management for NATIVE applications only. Use for native GUI apps without APIs, OS dialogs, and desktop automation; NOT for any browser/web task (use…
handoff-relay
Emit and resume cross-session handoff artifacts. Emit captures a session's mission, state, and next steps into a versioned file at explicit checkpoints; resume boots a new session from the artifact behind a continue/revise/archive decision checkpoint. Use for context handoffs between sessions, operators, or their…
oh-my-opencode-slim
Configure and improve oh-my-opencode-slim for the current user. Use when users want to tune agents, models, prompts, custom agents, skills, MCPs, presets, or plugin behavior. Also use when recurring workflow friction suggests a safe config or prompt improvement.
clonedeps
Clone important project dependency source code into an ignored local workspace so OpenCode can inspect library internals. Use when the user asks to clone dependencies, inspect dependency/source internals, understand SDK/framework behavior from source, debug library implementation details, or make core dependency repos…
codemap
Generate comprehensive hierarchical codemaps for UNFAMILIAR repositories. Expensive operation - only use when explicitly asked for codebase documentation or initial repository mapping.
worktrees
Manage Git worktrees as OMO safe isolated coding lanes for complex, risky, or parallel work.
