What's in it
Page one: the four branches a normal project has and what each is for. Page two: the nine-step loop you actually run every day, and how to write a commit message worth reading. Page three: how to undo things depending on how far the mistake travelled, what a merge conflict really is, and how to open a pull request someone will review.
No rebasing, no cherry-picking, no reflog. Those come later.
Who it's for
Anyone editing files on the live site. Anyone whose backup strategy is a folder called project-final-v2-REAL. Anyone who has heard of a pull request but has never opened one.
Test yourself
There's a companion quiz skill for Claude Code. Install it, then run /quiz-git and
it'll ask you eight questions one at a time and score you at the end —
quiz-git.
