Can it visualize class inheritance?

Yes, it can generate class hierarchy diagrams showing inheritance and composition in addition to module-level dependency graphs.

How does staleness detection work?

The skill compares the modification timestamps of source files with the metadata in your diagrams. If code has changed more recently than the diagram, it flags it as stale.

Does it support dynamic or runtime imports?

Code Visualizer uses static analysis; therefore, it captures explicit import statements but may not detect dynamic imports like those created via importlib or conditional logic.

Which programming languages are supported?

Currently, Code Visualizer is optimized for Python, utilizing its Abstract Syntax Tree (AST) for deep module and relationship analysis.

Learning & Documentation

Automatically generates and maintains Mermaid architecture diagrams from Python source code to ensure documentation stays synchronized with logic.

Code Visualizer is a specialized utility designed to bridge the gap between source code and architectural documentation. By parsing Python AST (Abstract Syntax Tree), the skill extracts import relationships, class hierarchies, and module dependencies to generate live Mermaid diagrams. Beyond simple generation, it features a proactive staleness detection engine that compares file modification timestamps and Git history against existing diagrams, alerting developers when documentation no longer reflects the current state of the code. It is an essential tool for PR reviews, refactoring, and maintaining transparent project overviews.
