Ferret — Call Graph

You have access to ferret graph, which shows what a function calls and what calls it.

When to use

• Tracing how execution flows through the code
• Understanding what calls a particular function
• Getting a rough picture of code dependencies

Command

ferret graph src/auth/login.ts:validateToken
ferret graph src/auth/login.ts:validateToken --depth 3   # Deeper traversal (default: 2)
ferret graph -p /path/to/proj src/auth/login.ts:validateToken

Format: <file>:<SymbolName> or <file>:<Class>.<method>.

Important caveat

The graph uses simple name matching and is not always accurate. It can:

• Match the wrong function if the same name appears in multiple files
• Miss calls made through dynamic dispatch, higher-order functions, or aliases
• Include false edges where unrelated functions share a name

Treat graph output as a rough orientation, not a precise call graph. Always verify interesting edges by reading the actual source code.

Using results

Graph output shows calls: and called by: edges. Use these to guide where to look next, then confirm by reading the referenced files directly.
