Agent Orchestrator manages fleets of AI coding agents working simultaneously on a codebase. Each agent operates in its own isolated git worktree with a dedicated branch and PR. The orchestrator coordinates agents to autonomously respond to CI failures, address reviewer comments, and open pull requests. It is agent-agnostic (supports Claude Code, Codex, Aider) and runtime-agnostic (works with tmux, ConPTY, Docker), integrating with GitHub and Linear for tracker synchronization.
