This generates Architecture Decision Records in a structured format, which is honestly more useful than it sounds. You feed it a technical choice (Kafka vs SQS, microservices vs monolith) and get back a proper ADR with options, trade-offs, and consequences laid out. The format forces you to document why you picked something, not just what you picked. It can also evaluate existing designs or help you sketch out new components from requirements. Works best when you state your constraints upfront (budget, timeline, scale requirements) so it doesn't give you the theoretically perfect answer that's completely impractical for your situation.
