Codebase Navigation

Before modifying unfamiliar code, build a mental model.

Exploration strategy:

1. Start with entry points: main.py, __init__.py, index.ts, App.tsx.
2. Follow imports to understand dependency structure.
3. Find the data model first — it shapes everything else.
4. Read tests: they document expected behavior better than comments.
5. Check git log: recent commits explain why things are the way they are.

Efficient search:

• Use file pattern search (glob) to find files by name/extension.
• Use content search (grep) to find where a function/class is defined vs. called.
• Search for the error message text to find the source location directly.
