Overview#

After having Copilot rewrite a bunch of files, ever found yourself thinking “wait, what exactly changed?”

Opening each file one by one to check is tedious. The /diff command gives you a quick overview of all changes.

Run this in Copilot CLI:

/copilot> /diff

All changes in the current directory are displayed as a diff — similar to git diff.

Scenario	Why it helps
After Copilot modified multiple files	See all changes at a glance
Before committing	Catch any unintended changes
Session recap	Understand what was done

If you review the diff and don’t like what you see, use /rewind to undo the last change.
