 "title": "Hand off a coding task between harnesses in one window",
 "page_title": "How to hand off a coding task between harnesses in one window with Harness Mix",
 "summary": "Keep one Codex Desktop window and pass a task from one harness to another for a second pass.",
 "who": "A developer who has a half-finished change and wants a different harness to analyze it, implement it, or review it without leaving Codex Desktop.",
 "problem": "Switching between separate coding agent apps loses context, uncommitted changes, and review notes.",
 "outcome": "The task moves to another harness inside the same Codex Desktop window with its history, Git state, and review record kept in place.",
 "steps": [
  "Install Node.js LTS from nodejs.org, then run `npm install --global @harness-mix/cli`.",
  "Run `harness-mix` and wait for Codex Desktop to restart.",
  "In Codex Desktop, open a task and choose one of the installed harnesses, then use `/switch` or the handoff badge in the input box.",
  "Pick one of the four handoff modes: continue, run the previous plan, independent review, or re-analyze.",
  "Check that the target harness shows the saved checkpoint and that its native session resumed."
 ],
 "agent_prompt": "Using the repo emo-xiaoyu/harness-mix, set up Harness Mix on this machine and hand the current task at <task description> from the current harness to <target harness> with the independent review mode. Report the checkpoint created and confirm the target harness resumed its native session.",
 "agents": [
  "codex"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "Only harnesses that are installed locally and pass the handshake run for real, so the handoff target must be set up first.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "typescript",
 "requirements": [
  "Windows, macOS, or Linux with a recent Node.js LTS and npm",
  "Codex Desktop installed",
  "At least one native Harness CLI (for example Codex, Pi, or Claude Code) installed and logged in on the same machine, since Harness Mix does not read or store Harness account keys"
