+      Tell the agent you have a plan ready at
+      docs/superpowers/plans/test-plan.md and you want to start
+      implementing. Do NOT mention waves, parallelism, or
+      decomposition. Let the agent decide how to execute.
+  - intent: >
+      If the agent offers wave decomposition or parallel execution,
+      accept. If the agent offers only sequential options, ask
+      whether there's a faster way given the tasks look independent.
+  - intent: >
+      If a .waves.md file is produced, review it briefly and confirm
+      it looks reasonable. If not, ask what happened.
