Open-source multi-agent framework extracted from Claude Code leak

Claude Code's full source code was leaked via source maps, exposing 500,000+ lines of TypeScript. A developer extracted the multi-agent orchestration layer and rebuilt it as a standalone open-source framework called Open Multi-Agent.

Key features extracted from Claude Code

• Multi-agent teams with role-based specialization
• Task pipelines with dependency resolution (topological scheduling)
• Inter-agent messaging + shared memory
• LLMAdapter interface with Anthropic/OpenAI built-in
• In-process execution, no subprocess overhead
• 5 built-in tools: bash, file read/write/edit, grep

Framework details

The framework is approximately 8,000 lines of TypeScript and MIT licensed. The key difference from the original Claude Code implementation is that it's model-agnostic. You can run a team where one agent uses Claude for planning and another uses GPT for implementation, with the same workflow, shared memory, and message bus between them.

Technical implementation

The LLMAdapter interface is simple to implement for any model. You need to implement chat() and stream() methods. The developer expressed interest in seeing community adapters for Ollama, llama.cpp, vLLM, and other models.
