What it does
HAR is an open-source agent harness for AI coding workflows you can trust and verify. It runs every coding agent in its own isolated, consistent worktree, with deterministic validation, verifiable proof, and full observability. Run one agent or a whole fleet, with the same quality and control. It wraps the tools, tests, and CI you already use, and stays yours to customize.
