C4 Architecture Documenter
Generates comprehensive C4 model architecture documentation through a systematic, bottom-up analysis of existing codebases.
This skill automates the creation of architectural documentation following the C4 model (Context, Container, Component, Code). By employing a bottom-up approach, it starts by analyzing individual code directories and progressively synthesizes that data into high-level logical components, deployment containers, and system-wide context. This ensures that every technical detail is captured and accurately reflected in the final documentation, providing stakeholders with clear Mermaid diagrams, API specifications, and structural overviews directly from the source code.
