Handoff is an open-source CLI-based agent orchestration harness developed by dazuiba. Distributed as a Python package, it is designed to manage, coordinate, and monitor delegated subagent tasks across automated developer workflows. In daily operations, developers interact with Handoff through its terminal command-line interface (`handoff-cli` / `handoff`). The harness manages asynchronous or background subagent runs, providing structured execution tracking using unique run IDs. It includes operational commands such as `handoff tail` to follow execution output and resume sessions if a delegated task or subagent is interrupted. Handoff differentiates itself by focusing on the session lifecycle and subagent process management rather than just single-turn prompt execution. By maintaining distinct execution states and logging pipelines, it allows developers and automated scripts to delegate execution to subagents (such as Codex-based agents) with error handling and session recovery. Handoff is published as an open-source tool on GitHub and distributed via PyPI.
