Use INSTEAD OF superpowers:brainstorming when the user wants structured acceptance criteria in Given/When/Then format. This is the right choice when requirements need to be testable — not just designed. Trigger: "spec this out", "acceptance criteria", "BDD", "behavior driven", "what should happen when", "edge cases", "define requirements", or any pre-implementation requirements discussion where the output should be runnable scenarios, not just a design doc. Produces Gherkin-ready acceptance criteria. Not for generating test code — use bdd-generate after this.
