FAQPage Schema
How do I explain code with call graphs and pseudocode for feature documentation?

Explain code by generating Mermaid-based call graphs to visualize function relationships and breaking down logic into pseudocode with labeled cross-references. This structured framework improves clarity for feature discussions, onboarding, and documentation.

What's the best way to visualize function relationships for developer onboarding?

Visualize function relationships using Mermaid call graphs that map data flow and dependencies. Pairing these diagrams with pseudocode breakdowns provides a clear, structured explanation that accelerates developer onboarding and codebase comprehension.

Do I need external dependencies to generate Mermaid diagrams and pseudocode from code?

No external dependencies are required to generate Mermaid diagrams and pseudocode. The framework provides guidelines and templates to structure code explanations, ensuring consistent documentation without needing additional libraries or tools.

How does pseudocode with labeled cross-references improve code reviews?

Pseudocode with labeled cross-references improves code reviews by connecting each logical step directly to the codebase. This creates consistent documentation templates that make complex feature logic easier to follow and evaluate during reviews.

Can I use this approach to document data flow across multiple functions?

Yes, you can document data flow across multiple functions using Mermaid call graphs. The framework enforces visual mapping of function relationships combined with pseudocode breakdowns to clarify how data moves through the feature.
