Pi-cowboy is a multi-agent orchestrator that decomposes large coding tasks into subtasks and runs them in parallel across isolated copy-on-write Git worktrees. It supports mixing harnesses like Pi, Claude Code, Codex, and OpenCode, with live visibility via Herdr terminals and configurable concurrency limits.
