Execution Instructions

Assess Situation
- Show current state with git sl
- Identify what might need undoing
Execute Undo
- For quick: Run git undo, confirm
- For interactive: Run git undo -i, guide navigation
- For hide/unhide: Run respective command
Verify Result
- Show final state with git sl
- Confirm expected commits are present

Interactive Flow

User: /bl-undo

Agent: Checking last operation...

Last operation: git rebase -i main
  - Dropped: "feat: add OAuth"
  - Reordered: 2 commits

This will restore:
◆ abc1234 (main) initial commit
┃
◯ def5678 feat: add auth base
┃
◯ ghi9012 feat: add OAuth       ← Will be restored
┃
◯ jkl3456 feat: add Google login
┃
● mno7890 feat: add GitHub login

Undo this operation? [y/n]:

User: /bl-undo -i

Agent: Opening interactive undo...

git undo -i

This opens a browser interface. Use:
  ← → arrow keys to navigate through time
  Each state shows the smartlog at that point
  Find the state BEFORE your mistake
  Press Enter to select, then y to confirm

[User navigates in terminal]

After user confirms...

◆ abc1234 (main) initial commit
┃
◯ def5678 feat: add User class
┃
◯ ghi9012 feat: add validation
┃
● jkl3456 feat: add repository

Restored to state before the bad rebase.
All 3 commits recovered.

User: /bl-undo --hide abc1234

Agent: Hiding commit abc1234...

Before:
◆ main initial commit
┃
◯ abc1234 feat: experimental  ← Will be hidden
┃
◯ def5678 feat: add User class
┃
● ghi9012 feat: add validation

git hide abc1234

After:
◆ main initial commit
┃
◯ def5678 feat: add User class
┃
● ghi9012 feat: add validation

Commit hidden from smartlog.

⚠️  Warning: Hidden commits may be garbage collected.
To restore later: /bl-undo --unhide abc1234

Common Recovery Scenarios

Bad Rebase Removed Commits

User: I accidentally dropped a commit during rebase!

Agent: Let's recover it with interactive undo...
/bl-undo -i
Navigate to state before the rebase, select, confirm.

Wrong Commit Amended

User: I amended the wrong commit!

Agent: Quick undo will restore it...
/bl-undo
Confirm to restore pre-amend state.

Stack Got Messed Up

User: My stack is completely messed up after multiple operations

Agent: Interactive undo can go back multiple operations...
/bl-undo -i
Navigate back to when the stack was correct.
May need to go back several states.

Want to Hide Experimental Work

User: I have some experimental commits cluttering my smartlog

Agent: Hide them to clean up the view...
/bl-undo --hide <hash>
They won't show in git sl but can be restored.

Error Handling

Error	Resolution
"Nothing to undo"	No recent undoable operations
"Working directory dirty"	Stash or commit changes first
"Would cause conflicts"	Use `-i` to find different restore point
Lost uncommitted changes	Cannot recover - check editor undo
Pushed commits	Must revert on remote instead

Tips

Commit before risky operations - Makes undo possible
Use -i for complex recovery - Better visibility of history
Hidden commits aren't permanent - May be garbage collected
Check result immediately - Run git sl after undo
