SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Explains how parts of the codebase work by tracing execution paths, listing the key files involved, and pointing to backing tests to speed up understanding and debugging.

Core Features & Use Cases

  • Map the execution path of a feature or component, with file references and concise explanations suitable for non-experts.
  • Trace code flow across modules to locate responsible files, functions, and tests.
  • Use cases include onboarding new developers, performing quick debug sessions, and answering questions like "how does X work" or "where is X handled" with a clear, test-backed narrative.

Quick Start

Ask it to explain how the login flow works in the codebase.

FAQPage Schema
How do I trace and explain an execution path across my codebase?

Tracing an execution path involves outlining how a feature is implemented by following code flow across modules, pointing to key files with line references, and identifying backing tests to provide a clear, test-backed narrative for debugging.

What is the best way to locate where a specific feature is handled in the code?

Locating where a feature is handled requires tracing the code flow across modules to pinpoint responsible files and functions, validating the execution path against test evidence, and highlighting any untested gaps in the implementation.

How do I use code tracing to speed up onboarding for new developers?

Code tracing accelerates onboarding by mapping feature execution paths into concise summaries with file:line references, explaining how components interact across the codebase, and providing test evidence to validate the documented behavior.

Can I map code flow across modules without missing untested areas?

Mapping code flow across modules requires identifying the execution path with file:line references and validating it against backing tests. The process explicitly highlights gaps to ensure no untested areas are left unaddressed in the trace.

What's needed to generate a test-backed walk-through of a feature flow?

Generating a test-backed walk-through requires tracing the feature's execution path, listing key files with file:line references, and correlating the flow with existing tests to produce a structured summary that identifies any coverage gaps.
