Oh My ClaudeCode (OMC) is a multi-agent orchestration plugin that transforms Claude Code from a single-agent terminal tool into a coordinated team of 19 specialized AI agents. Built by Yeachan Heo and installable directly from Claude Code's plugin marketplace, OMC provides five distinct execution modes: Autopilot for fully autonomous development from a high-level description, Ultrawork for maximum parallelism with up to five concurrent workers, Sisyphus for relentless iteration until architect verification passes, Swarm for coordinated agents on a shared task list using Claude Code native teams, and Deep Interview for Socratic requirement gathering before implementation begins.
The plugin's smart model routing automatically delegates simple tasks to Haiku and complex reasoning to Opus, reportedly saving 30-50% on token costs without sacrificing output quality. Its built-in orchestration skills cover everything from structural code analysis via AST-grep to visual QA through screenshot comparison, and a tracer agent for evidence-driven root-cause analysis. The HUD statusline provides real-time observability into agent activity, token usage, and session state. OMC also integrates with OpenClaw gateways for forwarding session events and supports multi-AI orchestration across Claude, Gemini, and Codex simultaneously.
Since its initial release, OMC has grown explosively — reaching over 20,000 GitHub stars, trending as the #1 repository on GitHub, and shipping over 200 releases with continuous improvements to team orchestration, security hardening, and MCP integration. The project includes a comprehensive hook system with 31 lifecycle hooks, anti-AI-slop cleaning workflows, and auto-resume capabilities for rate-limited sessions. For developers already using Claude Code, OMC adds a powerful orchestration layer with zero configuration: install the plugin, run omc-setup, and start delegating.
