+      Ask the agent to decompose the plan at
+      docs/superpowers/plans/test-plan.md into waves. The plan has
+      three tasks that each create a file named types.ts but in
+      different directories (src/auth/, src/users/, src/billing/).
+      Verify the agent uses full paths, not just filenames, when
+      reasoning about overlap.
+  - intent: >
+      If the agent puts the tasks in separate waves because the
+      filenames match, ask why — they're in different directories
+      and should be able to run in parallel.
