Safe Git Guard

Name: safe-git-guard
Author: svenja-dev

Skill to prevent destructive Git operations

Trigger

This skill activates automatically on these commands:

git reset --hard
git checkout -- <file>
git clean -fd
git rebase (without explicit confirmation)
git push --force

Rules

FORBIDDEN (never execute):

git reset --hard - Deletes uncommitted changes irreversibly
git push --force on main/master - Can destroy remote history
git clean -fd - Deletes untracked files irreversibly

WARNING + BACKUP required:

git checkout -- <file> - Overwrites local changes
- BEFORE execution: Create backup
- git stash push -m "backup-before-checkout-$(date +%s)"
git reset HEAD~n - Resets commits
- BEFORE execution: Create tag
- git tag backup-before-reset-$(date +%s)
git rebase - Modifies history
- BEFORE execution: Create backup branch
- git branch backup-before-rebase-$(date +%s)

Workflow for Destructive Operations

1. STOP - Don't execute immediately
2. BACKUP - Save current state (tag/branch/stash)
3. ASK - "Are you sure? What will be lost?"
4. CONFIRM - Explicit "Yes, I understand the risk"
5. EXECUTE - Only then run the command

Example Dialog

User: "Undo the last 3 commits"

Claude (with this skill):

WARNING: DESTRUCTIVE OPERATION DETECTED

You want to run `git reset HEAD~3`. This would:
- Remove 3 commits from history
- Changes become "unstaged" (--soft) or deleted (--hard)

Creating backup:
> git tag backup-YYYYMMDD-pre-reset

Should I proceed? (Answer with "Yes, proceed with reset")

Protected Branches

Configure in your project's CLAUDE.md:

protected_branches:
  - main      # Production branch, never force-push
  - master    # Legacy production branch
  - develop   # Development branch, PR only
  - release/* # Release branches, approval only

Integration with No-Touch Zones

This skill respects No-Touch Zones defined in CLAUDE.md. When changes affect protected files: Additional warning + Impact Analysis.

Configuration

Add to your CLAUDE.md:

### Git Safety Rules

Protected Branches:
- main, develop, release/*

No-Touch Zones (require explicit approval):
- src/auth/**
- src/core/**
- config/production.*
