What do you want?To make sure I understand: we're building [X] for [user]. Out of scope: [Y]. Is that right?
What about errors?What should happen when [error case]? Do we show a message, retry, or fail silently?
How important is this?If we have to cut scope, what's the priority order?

You: Before I start, I want to confirm scope. We're building the checkout flow for logged-in users. Guest checkout is phase 2. Payment failures: we show an error and let them retry. Sound right?

PM: Yes. One thing: we need to support saved cards.

You: Got it. I'll add that. I'll send the spec for your sign-off before I build.
