h5i-python

Multi-agent coding is more than launching agents or letting them chat. h5i-python lets you program the full development process in Python: Claude Code, Codex, and other runtimes can implement independently, review one another, revise, run neutral tests, compete, and safely apply the winner. Each agent works in an isolated Git worktree, making every run reproducible and auditable. Open source, with 40 multi-agent LLM paper workflows included.
