write-architecture-roadmap
Create or substantially revise two separate, tightly coupled Markdown deliverables—a technical architecture design document and an executable development roadmap. Use when turning product ideas, prior discussions, requirements, codebase findings, feasibility conclusions, remediation findings, or an existing proposal into an implementation-ready system design plus dependency-ordered delivery plan. Trigger for technical architecture documents, system design books, architecture整改方案, phased implementation plans, MVP-to-platform roadmaps, P0/P1 remediation roadmaps, or paired architecture-and-roadmap outputs. Support greenfield products, existing-system refactors, self-hosted services, multi-client applications, AI systems, developer tools, and research or engineering software.
