Cognitive context for your code
A map of your codebase you don't have to hold in your head.
See how your code connects to the rest of the system. What depends on it. What it depends on. Follow the call paths across files and modules.
"How does auth work?" gets an answer grounded in your actual code. Graph-traversal, not keyword matching.
Parsing happens on your machine. Only the graph structure goes to the API. No source code, no string literals, no secrets.
