Previously it gave a narrow rule mainly about not delegating simple single-fact lookups when the location was already known. The new version actively recommends delegating whenever a task matches an available agent type, involves independent parallel work, or spans several files.\n\n**Why**\n\nThis pushes Claude to make more use of subagents for tasks that benefit from delegation, such as parallel or multi-file work, rather than doing everything inline in the main session.\n\n- Area: Agent Tool\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 2\/5"}
