Git Smart Fixup

Trigger

User invokes /smart-fixup or asks to split changes into fixup commits.

Arguments

• --from-head: Use the HEAD commit instead of staged changes (will reset HEAD and recreate as fixups)
• --dry-run: Show what fixup commits would be created without actually creating them
• --base <ref>: Specify the base branch (default: auto-detect master/main)

Instructions

Step 1: Determine the Base Branch and Commit Range

1. Find the merge base between current branch and main/master:

   git merge-base HEAD master
