The `Agent` tool is how Claude passes work to a subagent, a separate helper copy of Claude.\n\nThe new text gives Claude a default for unclear cases: \"When in doubt, don't spawn.\"\n\n**Why**\n\nThis text is part of Claude's own instructions, so the rewrite changes how often Claude starts helpers. When the choice is unclear, it is now told to do the work itself.\n\n- Area: Subagents\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
