oh-my-claudecode

// Overview

oh-my-claudecode — OMC — is a plugin and companion CLI that sits on top of Claude Code and turns it into a multi-agent workflow runner. Its pitch is that you should not have to learn the harness: after a one-time setup you describe a task in one line and OMC decides which specialised agents to run, in what order, and how to hand work between them.

It exposes two distinct surfaces that are easy to confuse. In-session slash commands (`/autopilot`, `/ralph`, `/execute`, `/deep-interview`, `/team`) run inside a Claude Code session and drive the native in-session workflows. The terminal CLI, installed from npm as `oh-my-claude-sisyphus`, adds commands that make sense outside a session — `omc setup`, `omc ask` to consult another provider, `omc team` to launch tmux CLI workers, and `omc lookout scan` as an advisory pre-flight danger scan before an unattended run.

Multiple model providers are first-class: the advisor flow routes to `claude`, `codex`, `gemini`, `antigravity`, `grok` or `cursor`, so a plan written by one model can be reviewed by another. Autopilot supports named stage profiles — ordered sequences such as `plan-build-qa` configured in `.claude/omc.jsonc` — with state, cancel, resume and HUD lifecycle carried across stages. The project also exports TypeScript helpers such as `createOmcSession()` for programs built on the Claude Agent SDK.

// What it does

• `/autopilot` runs a task end to end through staged agents; named stage profiles pin the sequence, with cancel, resume and crash-safe state
• Two surfaces — in-session slash commands inside Claude Code, and an `omc` terminal CLI for setup, advisors and workers
• Cross-provider advisors: route a review or second opinion to Codex, Gemini, Grok, Cursor or Antigravity from inside a Claude session
• Parallel teams — `omc team` launches tmux CLI workers, `/team` runs the in-session native team workflow
• `omc lookout scan` reads a task briefing and the workspace before an unattended run and reports danger findings with severities and CI-friendly exit codes
• An SDK surface (`createOmcSession()`, prompt expansion helpers) for local Node.js programs on `@anthropic-ai/claude-agent-sdk`

// Getting started

The marketplace install is the recommended path for Claude Code users. The two slash commands must be entered one at a time — pasting both lines together fails.

/plugin marketplace add https://github.com/Yeachan-Heo/oh-my-claudecode

/plugin install oh-my-claudecode

npm i -g oh-my-claude-sisyphus@latest

# inside a Claude Code / OMC session
/omc-setup

# from your terminal
omc setup

/autopilot "build a REST API for managing tasks"

/autopilot --workflow plan-build-qa "build a REST API for managing tasks"

omc ask codex "review this patch"
omc team 2:codex "review auth flow"
omc lookout scan --brief "..." --json --strict

// When to use it

• Hand a whole feature to Claude Code as one sentence and let staged agents plan, build and QA it
• Get a second opinion on a patch from a different vendor's model without leaving the session
• Run several coding workers in parallel on independent parts of a task
• Scan a task briefing for risky operations before starting an unattended run in CI
