Analyze what a design forecloses and what it opens — second-order effects, irreversible actions, path foreclosure, data implications, future-design lock-in. Use this whenever the user asks about side effects, what happens after a user clicks, what gets stored or exposed, whether an action is reversible, what this prevents the team from doing later, or knock-on effects on other features. Also trigger when the user is about to ship a destructive flow (deletion, payment, account changes) and asks for a review. Produces a structured decision artifact with score, criteria, and anti-pattern matches.
