Save points for your whole project.
Git records every change to your project, so you can always go back. You'll mostly ask the agent to use it, but you need the five words.
Five Words
Repository
The project folder plus its full history.
Commit
A save point with a short note: “Added date validation.”
Diff
Exactly what changed between two save points, line by line.
Branch
A safe copy to experiment on without touching the main version.
Push
Send your save points to GitHub, off your laptop.
Commit early. Commit often. Commit before every ask.
