A host can set classifyHandoff false to skip the classifier deciding whether a subagent hands control back.
What's wrong with this entry?
When a subagent finishes in permission mode auto, Claude Code normally runs a classifier to decide whether control hands back to you. A host or SDK integration can now set classifyHandoff: false in its config to skip that classifier entirely. It applies to both local subagents and cloud agents run with isolation: 'remote'. The guard only fires in mode auto, so nothing changes unless a host opts out.
- Skips are logged as a
tengu_auto_mode_decisionevent with decisionskipped_enveloped_handback, plus the handoff marker and the tool-use count. - With no host opt-out, the classifier runs exactly as before.
skipped_enveloped_handback
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
