description: Squash consecutive co-authored commits into one. Always asks for confirmation before proceeding.

The user has invoked /squash. Follow these steps exactly:

Run git log --format="%H %s%n%b" to identify all consecutive commits from HEAD that contain a Co-Authored-By: trailer. Stop at the first commit that does not have one - that is the base.
Show the user:
How many commits will be squashed
The base commit (first one NOT being squashed)
A preview of the squashed commit message (see format below)
Ask the user for explicit confirmation before proceeding. This is a destructive action.
Upon confirmation:
Run git reset --soft <base-commit-hash> to unstage all squashed commits
Commit with the message format below

Subject line: Multiple changes
Body: each squashed commit's subject line and body, listed from oldest to newest, separated by blank lines. Omit the Co-Authored-By trailers from the body.
Final line: Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
