Part 1 showed how LLM-generated specs lose the rules between microservices. Part 2 introduces archspec, an open source Claude Code plugin that initializes a YAML service contract, generated architecture docs, Mermaid diagrams, and pre-commit checks so idempotency, Outbox, consumers, and service links stay explicit.
