Module 4 · Read every diffLesson 3 of 3

Goal: Confirm you can review an agent's diff with the checklist, spot unsafe input handling, and undo a change at each stage.

Four questions: three on this module, one on Module 2. Every answer explains itself, right or wrong.

An agent's diff for a small bug fix also changes package.json, adding a package you don't recognise. What comes first?
In the export review, which checklist question led to the CSV injection bug?
You've committed an agent's change on your branch but not pushed it. It's wrong. Which command undoes it and keeps a record?
From Module 2: an exported app runs locally only after you create a .env file with DATABASE_URL. What goes into Git?

Retry as often as you like.
