Why SDD Breaks Down in Microservices: Part 2. Why I Built Archspec to Keep Service Context Explicit

This story was originally published on HackerNoon at: https://hackernoon.com/why-sdd-breaks-down-in-microservices-part-2-why-i-built-archspec-to-keep-service-context-explicit. I built archspec, an open source Claude Code plugin that turns microservice architecture rules into YAML contracts, docs, diagrams, and commit checks.

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.
