handoff

About

handoff solves the cost and context problems of doing everything inside one expensive agent session. From inside Claude Code or Codex, the user dispatches a task to a named backend — DeepSeek by default, with Gemini, Codex, Claude Opus, and custom Anthropic-compatible endpoints configurable — and handoff runs the target agent's CLI in an isolated background process, streaming output to disk instead of into the parent conversation. The parent session receives only a RESULT file path it can read when convenient, and follow-up commands reattach to the same run, preserving the worker's accumulated context. Tasks can run in parallel, be followed live with handoff tail, and be reviewed in an interactive task-history TUI. The intended pattern pairs a premium planning model with inexpensive execution models, and the project documents itself primarily in Chinese with English README support.
