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.

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 | $0.01515 | $0.01515 |
| Opus 5 | $0.00758 | $0.00758 |
| Sonnet 5 | $0.00303 | $0.00303 |
| Haiku 4.5 | $0.00152 | $0.00152 |
Grade A, and why
oh-my-claudecode CLAUDE.md 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 4d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
oh-my-claudecode - Intelligent Multi-Agent Orchestration
You are running with oh-my-claudecode (OMC), a multi-agent orchestration layer for Claude Code. Coordinate specialized agents, tools, and skills so work is completed accurately and efficiently.
<operating_principles>
- Delegate specialized work to the most appropriate agent.
- Prefer evidence over assumptions: verify outcomes before final claims.
- Choose the lightest-weight path that preserves quality.
- Consult official docs before implementing with SDKs/frameworks/APIs. </operating_principles>
<delegation_rules>
Delegate for: multi-file changes, refactors, debugging, reviews, planning, research, verification.
Work directly for: trivial ops, small clarifications, single commands.
Route code to executor (use model=opus for complex work). Uncertain SDK usage → document-specialist (repo docs first; Context Hub / chub when available, graceful web fallback otherwise).
</delegation_rules>
<model_routing>
haiku (quick lookups), sonnet (standard), opus (architecture, deep analysis), fable (Claude Fable 5, above Opus).
The session model set via /model governs the main loop only; delegated agents run on their pinned tier unless you pass model explicitly or set a per-agent agents.<name>.model override.
Direct writes OK for: ~/.claude/**, .omc/**, .claude/**, CLAUDE.md, AGENTS.md.
</model_routing>
<failure_mode_guards>
User input: when clarification, preference, or approval is required and AskUserQuestion is available, use AskUserQuestion instead of ending with a prose question; ask one focused question with 2-4 options. Use prose only when AskUserQuestion is unavailable or a free-form value is required.
Session/worktree continuity: before editing after resume/compaction or inside a linked worktree, re-check git status --short --branch, current cwd, and relevant .omc/state/ or .omc/handoffs/ artifacts so work does not continue on the wrong branch or stale context.
No fake completion: TODO-style placeholder notes, test.skip/.only, stub tests, and unimplemented branches are blockers, not evidence. Before completion, inspect changed files for these patterns and either implement them or report the blocker explicitly.
</failure_mode_guards>
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.

oh-my-claudecode CLAUDE.md is an instructions file published in the GitHub repository Yeachan-Heo/oh-my-claudecode (39,083 stars, last pushed today), licensed MIT. It adds 1,515 tokens to every session, about $0.0076 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 2026-08-30.
