Check yourself

Check what you remember from this chapter. Answer each flashcard in your head, then turn it over and choose Got it or Missed it. Cards you do not know yet come back sooner. The quiz mixes the questions from this chapter's pages and asks 10 at a time.

Before you move on. You should be able to do these without notes:

1. Say where the bottleneck moved when agents began writing code, and name the two skills that now matter most.
2. Name the four layers of trust in agent-written code, and show from a branch's history that its tests came first and failed for the right reason.
3. Say what a pull request holds that a file does not, and what it still lacks that evidence supplies.
4. Read a short diff and say what one changed character does to the program's meaning.
5. Show where your desktop app displays the agent's changes, and say why you still read git diff main...<branch> before a pull request.
6. Name three git commands to approve without worry, and two to refuse until you know exactly what they remove.
7. For a described bug, name the check that should catch it, and say whether that check is blocking.
8. Write three lines of a review rules file, and say why it is read from main.
9. Say what to do with an Important finding, a nit and a pre-existing bug.
10. Set the risk tier for a described change, and say who must approve it.
11. Explain when a feature flag that is off lowers the risk of a merge. Say what still takes effect at the merge, and how you would undo it.

From Chapter 16 on, every change to brightline-ap arrives as a reviewed pull request.
