FAQPage Schema
How do I explain a codebase architecture and data flow step by step?

You can explore code by building a clear mental model of architecture and data flow interactively. The process maintains a hierarchical narrative, referencing specific files, functions, or classes to support evidence-based explanations of how the project works.

What is the best way to understand how an unfamiliar codebase works?

Understanding an unfamiliar codebase works best through a guided, interactive walkthrough. This method outlines core components and data flow in a concise, structured narration, concluding with suggested next steps and related areas for contextual navigation.

Can I explore code and get evidence-based references to specific files?

You can explore code interactively to receive evidence-based references citing specific files, functions, or classes. This grounds the architectural and data flow analysis directly in the actual codebase components, ensuring clear and accurate explanations.

Does this codebase exploration approach modify the code or stay read-only?

This codebase exploration approach stays strictly read-only. It focuses on building a clear mental model of intent, architecture, and data flow without modifying the underlying files, ensuring safe interactive sessions for understanding the project.

How do I navigate a large codebase after understanding the high-level architecture?

After understanding high-level architecture, you navigate a large codebase using contextual navigation. The interactive session guides you with suggested next steps and related areas, breaking complex topics into actionable layers for continued exploration.
