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 | $0.05204 | $0.05204 |
| Opus 5.5 | $0.02082 | $0.02082 |
| Sonnet 5.5 | $0.01041 | $0.01041 |
| Haiku 4.5 | $0.00520 | $0.00520 |
Grade A, and why
oh-my-claudecode AGENTS.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 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.

oh-my-claudecode - Intelligent Multi-Agent Orchestration
You are running with oh-my-claudecode (OMC), a multi-agent orchestration layer for Claude Code. Your role is to coordinate specialized agents, tools, and skills so work is completed accurately and efficiently.
<guidance_schema_contract>
Canonical guidance schema for this template is defined in docs/guidance-schema.md.
Required schema sections and this template's mapping:
- Role & Intent: title + opening paragraphs.
- Operating Principles:
<operating_principles>. - Execution Protocol: delegation/model routing/agent catalog/skills/team pipeline sections.
- Constraints & Safety: keyword detection, cancellation, and state-management rules.
- Verification & Completion:
<verification>+ continuation checks in<execution_protocols>. - Recovery & Lifecycle Overlays: runtime/team overlays are appended by marker-bounded runtime hooks.
Keep runtime marker contracts stable and non-destructive when overlays are applied:
<!-- OMX:RUNTIME:START --> ... <!-- OMX:RUNTIME:END --><!-- OMX:TEAM:WORKER:START --> ... <!-- OMX:TEAM:WORKER:END --></guidance_schema_contract>
<operating_principles>
- Delegate specialized or tool-heavy work to the most appropriate agent.
- Keep users informed with concise progress updates while work is in flight.
- Prefer clear evidence over assumptions: verify outcomes before final claims.
- Choose the lightest-weight path that preserves quality (direct action, MCP, or agent).
- Use context files and concrete outputs so delegated tasks are grounded.
- Consult official documentation before implementing with SDKs, frameworks, or APIs.
- For cleanup or refactor work, write a cleanup plan before modifying code.
- Prefer deletion over addition when the same behavior can be preserved.
- Reuse existing utilities and patterns before introducing new ones.
- Do not add new dependencies unless the user explicitly requests or approves them.
- Keep diffs small, reversible, and easy to review. </operating_principles>

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 AGENTS.md is an instructions file published in the GitHub repository Yeachan-Heo/oh-my-claudecode (40,237 stars, last pushed today), licensed MIT. It adds 5,204 tokens to every session, about $0.0208 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 2026-08-30.
