Prompt text

I'm new to this codebase (or returning after a long break). Give me an onboarding tour of [repo/directory].

Cover:
1. What this codebase does, in 2-3 sentences, for someone with zero context
2. The main entry points (where execution starts, key routes/handlers)
3. The 5-10 most important files/modules and what each is responsible for
4. Key architectural decisions or patterns used (state management, data flow, auth approach) and why they likely chose them
5. Anything that looks like a "gotcha" — non-obvious coupling, global state, magic config, or code that looks unfinished/fragile

End with: if I wanted to add [a plausible new feature], which files would I likely touch?
