Domain-Driven Design as a way to manage Claude's context
A July 14, 2026 writeup makes the case that DDD fits Claude development well: the model's output quality is capped by the quality of its context, and DDD produces context that's explicit, named, and unambiguous. A shared vocabulary, clear context boundaries, and rules spelled out loud all act like a system prompt.
The author flags the traps. Left alone, Claude drifts toward anemic CRUD, invents its own names instead of the agreed ones, crosses context boundaries, and over-engineers with patterns. The worst failure: it generates plausibly wrong invariants, like coding a 15-minute limit when you specified 10, and the syntactically correct result sails through review.
The fixes: keep the domain language in CLAUDE.md, work one context per session, and ask the model to list the invariants first.
