When should I use semantic navigation vs. text search?

Use semantic navigation for code structures like classes and functions. Use text search for non-code patterns, such as string literals, comments, or configuration values.

Can I find where a function is called across the whole project?

Yes, the find_referencing_symbols tool allows you to find all call sites and usages of a specific symbol across your entire codebase.

How does Serena Navigator save tokens during code exploration?

It uses a tiered approach: first getting a symbol overview, then locating specific symbol coordinates, and finally reading only the relevant line ranges instead of loading entire large files.

Does this skill help with understanding project architecture?

Absolutely. By using get_symbols_overview and integrating with project memory, it helps Claude build and recall a high-level map of your software architecture.
