I just landed in an unfamiliar codebase. Here’s what I’m looking at:
[paste code, file tree, or attach files]
Walk me through it like an experienced teammate onboarding me:
- What does this thing do — one sentence, no jargon
- The main entry point and how data flows through it
- The key files/functions and what each one is responsible for
- Any patterns, conventions, or “gotchas” a newcomer would trip on
Don’t just narrate the code line by line. Give me the mental model so I can navigate it myself.
