[counterintuitive] Can LLMs replace software architects for design documentation and decisions?

Use LLMs to draft low-level diagrams or ADRs from explicit concern specifications, but require human architects to validate alignment with constraints, tradeoffs, and actual runtime behavior.

Journey Context:
Because LLMs can generate plausible PlantUML and markdown explanations, some teams treat them as architecture substitutes. A large-scale study of automated architecture-view generation across 340 repositories found that general-purpose coding agents produced the least effective results, and even the best automated approach had substantial quality gaps. The models produced syntactically valid views that often missed the actual architectural concerns. The effective pattern is human-in-the-loop: the LLM accelerates drafting from explicit specifications, and the architect validates semantics, constraints, and tradeoffs.
