oh-my-claudecode

oh-my-claudecode turns one Claude Code session into a small dev team. Type /autopilot "build a REST API" or /team 3:executor "fix all TypeScript errors" and it plans, builds, verifies and loops on fixes with specialized agents, no prompting every step. It's a free, MIT-licensed plugin from the Claude Code marketplace, also published on npm as oh-my-claude-sisyphus (same author, odd name).

Nothing to host. It runs inside your session and keeps state, logs and transcripts in a local .omc/ folder. From the terminal, omc team opens tmux panes running Codex, Gemini, Grok, Cursor or Claude CLIs, so a second model can review the first. There is no paid tier, but you need a Claude Pro or Max plan or an Anthropic API key, plus accounts for any other CLI you call. Solo developers and small teams get the most from it; larger teams should pin a version before standardizing.

The catch: it ships up to three releases a day and drops features along the way (swarm became team, the Codex and Gemini MCP servers went in v4.4), so older setups break. Parallel agents chew through usage limits fast. Plain Claude Code subagents cover much of this with fewer moving parts.
