 "what": "Harness Mix is a local kernel that adds a native Codex Desktop interface for connecting many coding agent harnesses and passing tasks between them.",
 "why": "",
 "language": "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"
 ],
 "audience_note": "Developers who already use Codex Desktop or several coding agent CLIs and want to switch, compare, or coordinate them in one window.",
