A commit is a saved snapshot of your code at a specific point in time — like a checkpoint in a video game. In vibe coding, commits are crucial because AI can make sweeping changes to your codebase, and commits let you go back to a working state if something breaks.
Commits are your safety net in vibe coding. When AI generates or modifies large chunks of code, things can go wrong — commits ensure you can always go back.
A commit captures:
| Bad Message | Good Message |
|---|---|
| "update" | "Add email validation to signup form" |
| "fix" | "Fix cart total not updating on item removal" |
| "changes" | "Refactor API routes to use server actions" |
| "wip" | "WIP: Dashboard layout with sidebar navigation" |
git add . (or specific files)git commit -m "describe what changed"git push to back up to GitHub.gitignore)git diff to see what AI actually changed
