Find your way around a large codebase.
Finds symbols, callers, and cross-file relationships to help users understand an existing codebase.
When to use it
Use for unfamiliar existing repositories, cross-file exploration, and sessions long enough to justify indexing; skip trivial single-file work.
Give it a question about an existing codebase; it uses the local graph to explain the relevant code and relationships.
What you provide
Requires Node 18 or newer on PATH.
Uses the codegraph command; the local setup installs it globally before initializing the project.
