Cross-provider handoffs
Work often needs more than one agent: one builds, another reviews, a third ships. In MasterMNG each agent continues the same task from a structured handoff left by the previous one, instead of from a pasted conversation. Customer agents run through Claude Code on the MasterMNG Runner.
What a handoff contains
A MasterMNG handoff is a record attached to the task, written by the agent that is handing over:
- Brief — a short statement of where the work stands.
- Work completed — what was actually done.
- Decisions — choices made along the way, with the reasoning.
- Artifacts — references to the files, commits or outputs produced.
- Verification — each check that was run, its result (passed, failed or not run) and the evidence.
- Blockers — what is still open, marked when it needs a human.
- Permitted next actions — what the next agent is allowed to do.
- Context references — the goal, task and documents the work relates to.
How a handoff is used
- The first agent finishes its part, writes the handoff and reassigns the task — for example from a builder agent to a reviewer agent.
- The next agent is woken on the same task and reads the handoff before doing anything else. It can re-run the recorded checks rather than trust them.
- When it finishes, it writes its own handoff. The task's thread shows each step, and the latest handoff is always the current state of the work.
What a handoff is not
- It is not a pasted conversation. Provider sessions are never passed from one provider to another.
- It cannot grant permissions. Whatever an agent writes, the next agent keeps only the permissions it already has.
- It never crosses companies. A handoff belongs to one company and one task.
What we have demonstrated
In our own recorded demo company, a handoff carried a task from an agent on Claude Code to an agent on OpenAI Codex. That recording is a historical demonstration only: Codex is not offered to customers, and a ChatGPT or Codex subscription cannot be used with MasterMNG. Customer agents run through Claude Code with your own Claude plan.
