FAQPage Schema
How do I analyze a codebase to understand its architecture and dependencies?

To analyze a codebase and understand its architecture, use the code-analysis modes to search, trace, and map dependencies. It provides evidence-based outputs with file paths and line numbers for comprehensive architectural understanding.

What is the best way to locate specific code patterns within a large project?

The best way to locate specific code patterns is by using the search mode with Glob and Grep tools. This approach yields evidence-based results, showing exact file paths and line numbers where the patterns occur.

Can I trace how a new feature impacts existing code during a code review?

Yes, you can trace how a new feature impacts existing code during a code review. The trace mode locates functional patterns and maps dependencies to show the precise impact across the codebase.

Does this code explanation tool support onboarding developers at different skill levels?

Yes, this code explanation tool supports onboarding developers at different skill levels. The explain mode deep-dives into code, configs, and docs to teach functionality tailored to specific user intents.

How do I search for a specific function within an unfamiliar codebase?

To search for a specific function within an unfamiliar codebase, utilize the search mode. It leverages Glob and Grep tools to find code patterns and returns exact file paths and line numbers as evidence.

What are the limitations of automated code analysis for complex projects?

Automated code analysis for complex projects relies on file reading tools like Glob, Grep, and Read. It is limited to providing evidence-based outputs from available source code, configs, and docs within the repository.
