When it finishes and returns a result directly, without a handback, Claude Code may now put a note about the tools it used at the start of that result. Before, only a handback warning and notes about being cut off were added there.\n\n**Why**\n\nThis can change what the main conversation sees from a subagent.\n\n- Area: Background Agents\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
