Undo Last Commit

Current State

!`git status`

Last Commit

!`git log -1 --pretty=format:'%h %s'`

Remote Status

!`git log origin/HEAD..HEAD --oneline 2>/dev/null || echo "No remote tracking"`

Instructions

Safely undo the last commit while keeping changes.

Security Check (MANDATORY)

IF the last commit is already pushed to remote:

• **REFUSE** to reset
• Explain: "Cannot undo pushed commits with reset."
• Suggest: `git revert HEAD` to create a reverting commit
• Ask confirmation before executing revert

IF the last commit is NOT pushed: 1. Ask confirmation: "Undo last commit? Changes will be kept." 2. Determine mode:

• `--soft` (default): Keep changes staged
• `--mixed`: Keep changes unstaged

3. Execute: `git reset $ARGUMENTS HEAD~1` 4. Show result with `git status`

Options

| Flag | Effect | |------|--------| | `--soft` | Keep changes staged (default) | | `--mixed` | Keep changes unstaged |
