Takes a Product Requirements Document and generates a comprehensive technical architecture specification for an Epic. Creates detailed Mermaid diagrams showing user, application, service, data, and infrastructure layers, then breaks down high-level features, technical enablers, and technology stack requirements. Outputs everything as a structured markdown file ready for your docs folder. Built for teams using TypeScript, Next.js, tRPC, and Docker who need to bridge the gap between product requirements and actual development work. The architecture specs include t-shirt sizing and technical value estimates, making sprint planning much more predictable.
