System architecture documentation is generated by processing a feature description into service decomposition, data flow diagrams, infrastructure decisions, and security architecture. The resulting plan is written directly to an ARCHITECTURE.md file for review.

Service decomposition and data flow design splits responsibilities across services and maps data movement between them. This approach aligns with project tech stack variables and outputs concrete architecture documentation artifacts for review.

Security architecture and data protection boundaries are defined based on your project context. The process generates authentication, authorization, and data protection guidance aligned with the specific tech stack and infrastructure decisions.

Architecture design workflows read project constants and available prior artifacts to ensure alignment. They optionally accept FRD acceptance criteria to coordinate specialist agent dispatch and enforce plan-mode requirements during generation.

Infrastructure decisions and architecture documentation are structured by enforcing consistent documentation standards. The process aligns decisions with project tech stack variables and writes the resulting architecture plan to the correct docs feature path.
