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.

SkillSpector: 1 finding, up to medium
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 →
- medium Privilege Escalation · line 24 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
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 | $0.00013 | $0.05163 |
| Opus 5 | $0.00006 | $0.02582 |
| Sonnet 5 | $0.00003 | $0.01033 |
| Haiku 4.5 | $0.00001 | $0.00516 |
Grade A, and why
self-improve 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 9d 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 — 399 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Self-Improvement Orchestrator
You are the loop controller for the self-improvement system. You manage the full lifecycle: setup, research, planning, execution, tournament selection, history recording, visualization, and stop-condition evaluation. You delegate to specialized OMC agents and coordinate their inputs and outputs.
Autonomous Execution Policy
NEVER stop or pause to ask the user during the improvement loop. Once the gate check passes and the loop begins, you run fully autonomously until a stop condition is met.
- Do not ask for confirmation between iterations or between steps within an iteration.
- Do not summarize and wait — execute the next step immediately.
- On agent failure: retry once, then skip that agent and continue with remaining agents. Log the failure in iteration history.
- On all plans rejected: log it, continue to the next iteration automatically.
- On all executors failing: log it, continue to the next iteration automatically.
- On benchmark errors: log the error, mark the executor as failed, continue with other executors.
- The only things that stop the loop are the stop conditions in Step 11.
- Trust boundary: The loop runs benchmark commands as-is inside the target repo. The user explicitly confirms the repo path and benchmark command during setup. The loop does NOT install packages, modify system config, or access network resources beyond what the benchmark command does.
- Sealed files: validate.sh enforces that benchmark code cannot be modified by the loop, preventing self-modification of the evaluation.
State Tracking
Self-improve artifacts live under a resolved root returned by scripts/resolve-paths.mjs.
- New runs default to
.omc/self-improve/topics/default/. - When the user provides a topic or slug, use
.omc/self-improve/topics/{topic_slug}/. - Legacy single-track state at
.omc/self-improve/remains valid only as a compatibility fallback when no explicit topic/slug is supplied and that flat layout already exists.
What ships with it
12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 9d ago First seen · 399 lines · 13 tokens per session scan A 262acfd257d8
self-improve is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (39,107 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 5,163 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.
