What branches does this skill protect by default?

It protects version branches (matching patterns like v1, v2), main/master branches, and completed task branches from deletion or history rewriting.

What is the purpose of the worktree verification?

It ensures that Claude operates within task-specific worktrees rather than the main /workspace, preventing environment pollution and accidental file changes.

Can I recover if a branch is accidentally modified?

Yes, the skill includes a recovery protocol using git reflog to restore branches to their original state if a safety check is bypassed.

How does it handle dangerous Git commands?

The skill intercepts commands like git filter-branch and git rebase, blocking them if they use global flags that could affect protected branches.

Does this skill allow force pushing?

It discourages standard force pushes and suggests --force-with-lease to ensure you don't overwrite work that you haven't yet pulled locally.

Security & Testing

Protects repositories by validating history-rewriting operations and safeguarding protected branches from accidental data loss.

The validate-git-safety skill serves as a critical protection layer for AI-driven development, ensuring that Claude Code does not perform destructive Git operations. It automatically identifies and protects sensitive branch patterns, such as versioned releases and main branches, while blocking dangerous commands like 'rebase --all' or 'filter-branch --branches'. By enforcing mandatory backups and worktree isolation, it provides a fail-safe environment for complex repository maintenance and history manipulation, allowing developers to leverage AI agents without the risk of irreversible repository corruption.

Key Features

01Mandates the creation of automated backup branches before any risky operation.

02Enforces M101 worktree verification to prevent operating on the main workspace during tasks.

032 GitHub stars

04Promotes safe alternatives such as --force-with-lease over standard force pushes.

05Blocks dangerous global flags like --all or --branches in history-rewriting commands.

06Automated detection and protection of version-patterned branches (e.g., v1, v21).

Use Cases

01Preventing the accidental rewriting of history on shared production or LTS branches.

02Ensuring filter-branch operations are scoped to specific targets rather than the entire repository.

03Safeguarding local environments by verifying the active worktree before executing task-specific logic.
