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

  1. The first agent finishes its part, writes the handoff and reassigns the task — for example from a builder agent to a reviewer agent.
  2. 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.
  3. 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.
