Does this skill automate Git backups?

Yes, it requires the creation of a timestamped backup branch before any history-rewriting operation is executed.

What happens if a Git operation goes wrong?

The skill provides a recovery protocol using git reflog to restore protected branches to their original commit position.

Does it support CAT (Cowwoc AI Tools) worktrees?

Yes, it includes specific logic to verify that operations are performed within task-specific worktrees rather than the main workspace to prevent environment pollution.

How does it handle dangerous commands like git push --force?

The skill identifies these commands as dangerous and suggests safer alternatives like --force-with-lease or blocks them if they target protected branches.

Which branches does this skill protect by default?

It protects the 'main' and 'master' branches, as well as any branch matching the version pattern 'v[0-9]+' (e.g., v1, v21), preventing them from being deleted or rewritten.

Developer Tools

Prevents accidental data loss by validating Git history-rewriting operations and protecting mission-critical branches.

The Validate Git Safety skill serves as a critical safeguard for developers and AI agents performing high-risk Git operations. It automatically identifies protected branches—such as main, master, and version-specific patterns (e.g., v1, v13)—and blocks dangerous commands that utilize destructive flags like --all or --branches. By enforcing worktree verification and mandating backup creation before any history-rewriting occurs, this skill ensures that repository integrity is maintained even during complex rebases, resets, or filter-branch operations.
