A subagent can hand its final report back to the agent that started it through a tool, which answers \"Report delivered to your caller.\" That report is now reviewed by the automatic safety check, and the check records more about each handoff: what kind it was, what the subagent was expected to hand back, and where the handoff happened.\n\nOutput recovered from a subagent that was cut off before finishing is labelled as partial output, with a note that the agent did not finish its task. Whether delivering the report ends the subagent's turn still depends on a remote switch, which is on unless it is switched off remotely.\n\n**Why**\n\nWhat a subagent hands back now passes the same safety review as other actions, so a report that the check objects to can be caught before it reaches the agent that asked for it.\n\n- Flag `tengu_purring_pine`: Not enough to say (read for one account on one subscription tier against v2.1.312; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Subagents\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
