About

Harness Mix connects native coding harnesses such as Codex, Pi, Oh My Pi, Claude Code, DeepSeek, OpenCode, Grok and Cursor CLI to the official Codex Desktop interface. It can hand a task from one harness to another in four modes, import and resume history from Pi, Claude and Codex, and show a harness's subagents as native cards. Model calls, tool execution and credentials stay with each harness, and only harnesses installed locally that pass a handshake run.

Use cases: coding, agent-orchestration, code-generation
