/rewind rolls back both the code and the conversation to an earlier checkpoint. Aliases: /checkpoint, /undo.

Three turns ago everything compiled. Then Claude refactored a helper and now nothing builds. /rewind takes you back to before the refactor so you can approach it differently — with the full conversation context reset to match.

The code rollback and the conversation rollback happen together. There’s no state mismatch where Claude remembers a change that’s no longer in the files.
