FAQPage Schema

How do I safely refactor code and trace dependencies across a large codebase?▼

Code navigation tools use semantic analysis to locate symbol definitions and trace references across your project. This maps dependencies before you modify implementation blocks, ensuring refactoring is safe.

What is semantic code analysis and how does it help with code understanding?▼

Semantic code analysis interprets project structure to provide high-level file overviews and detailed insights into specific code blocks. It facilitates code understanding by mapping relationships between symbols rather than just matching text.

Can I store and retrieve project patterns and architectural conventions for consistent development?▼

Yes, you can manage persistent memory files to store and retrieve project patterns, conventions, and architectural decisions. This maintains consistent development practices by retaining project context.

What's the best way to find all symbol references before changing a function?▼

The best way to find symbol references is using the code navigation feature to locate definitions and usages across the project. You can then analyze the current implementation and safely replace code bodies with confidence.

Does this codebase management tool work without external dependencies?▼

Yes, this codebase management tool operates with no external dependencies. It provides symbol analysis and refactoring capabilities natively once you activate the project for your current workspace.

How do I get started with semantic code navigation in my current workspace?▼

To get started with semantic code navigation, simply activate the project for your current workspace. This enables the tools to analyze files, locate symbols, and perform safe code modifications immediately.
