AI writes your architecture docs—from your code
AI that writes your architecture docs—from your code
Architecture docs often lag behind reality. This research shows a semi-automated way to generate Software Architecture Descriptions (SADs) directly from source code.
- Recover the system’s structure with reverse engineering to build a high-level component diagram.
- Use a large language model to highlight architecturally significant “core” components via prompt engineering.
- Generate state-machine diagrams that capture how components behave, guided by few-shot examples and domain hints.
Why it matters: less manual effort, faster onboarding, lower cognitive load, and documentation that stays aligned with the codebase.
Demonstrated on C++, but the approach is broadly applicable. It pairs human oversight with LLMs to abstract complexity and accurately reflect behavior.
