Getting AI to Explain Someone Else's Repo

AI can summarize code structure faster than you can grep

Some examples

• Pasting the file tree and asking for the entry point
• Asking what each top-level folder does
• Requesting a sequence diagram of one user action

Try it!

Open your favorite AI tool and try one of the examples above. Pick the one that matches what you are actually working on this week. Spend 10 minutes, no more. Notice what worked and what did not — that's the real lesson.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain codebase in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Getting AI to Explain Someone Else's Repo" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check entry point against a trusted source, teacher, adult, expert, or original document before you use it.
