domain-model

Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer. Ask the questions one at a time, waiting for feedback on each question before continuing. If a question can be answered by exploring the codebase, explore the codebase instead. Domain awareness During codebase exploration, also look for existing documentation: File structure Most repos have a single context: / ├── CONTEXT.md ├── docs/ │ └── adr/ │ ├── 0001-event-sourced-orders.md │ └── 0002-postgres-for-write-model.md └── src/ If a CONTEXT-MAP.md exists at the root, the repo has multiple contexts. The map points to where each one lives: / ├── CONTEXT-MAP.md ├── docs/ │ └── adr/ ← system-wide decisions ├── src/ │ ├── ordering/ │ │ ├── CONTEXT.md │ │ └── docs/adr/ ← context-specific decisions │ └── billing/ │ ├── CONTEXT.md │ └── docs/adr/ Create files lazily — only when you have something to write. If no CONTEXT.md exists, create one when the first term is resolved. If no docs/adr/ exists, create it when the first ADR is needed. During the session Challenge against the glossary When the user uses a term that conflicts with the existing language in CONTEXT.md , call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?" Sharpen fuzzy language When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things." Discuss concrete scenarios When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts. Cross-reference with code When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?" Update CONTEXT.md inline When a term is resolved, update CONTEXT.md right there. Don't batch these up — capture them as they happen. Use the format in CONTEXT-FORMAT.md . Offer ADRs sparingly Only offer to create an ADR when all three are true: Hard to reverse — the cost of changing your mind later is meaningful Surprising without context — a future reader will wonder "why did they do it this way?" The result of a real trade-off — there were genuine alternatives and you picked one for specific reasons If any of the three is missing, skip the ADR. Use the format in ADR-FORMAT.md .
