A subagent is a separate helper copy of Claude that takes on a piece of work, and the `Agent` tool is how one is started.\n\nThe new text tells Claude to brief a helper like a peer:\n\n- State the goal and what has already been ruled out.\n\n- Point it at the files and docs worth reading instead of retyping them.\n\n- Keep the scope explicit and narrow.\n\n**Why**\n\nThis text is part of Claude's own instructions, so the rewrite changes how Claude hands work over. Clearer, narrower briefs give the helper what it needs without repeating material it can read 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"}
