SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jq, and includes scripts (resource) components.

What problem does it solve?

Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them. This guards against destructive git operations during Claude Code sessions.

Core Features & Use Cases

  • Blocks dangerous commands like git push, git reset --hard, git clean, git branch -D, and git checkout/restore to prevent accidental destructive actions.
  • Provides guidance to install the hook either per-project (.claude/settings.json) or globally (~/.claude/settings.json) and to verify the protection.
  • Includes a ready-to-use script (scripts/block-dangerous-git.sh) and a simple verification workflow.

Quick Start

Copy the bundled script to the target location (.claude/hooks for project scope or ~/.claude/hooks for global scope), update the appropriate Claude settings.json to reference the block-dangerous-git.sh script, then verify by attempting a blocked command.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I block dangerous git commands like git push or reset --hard in Claude Code?▼

You can block dangerous git commands in Claude Code by installing a PreToolUse hook that intercepts operations like git push and git reset --hard. The hook enforces guardrails by running a shell script before tool execution.

Can I set up git hooks globally for all my Claude Code projects?▼

Yes, you can configure git hooks globally for Claude Code projects by copying the block-dangerous-git.sh script to ~/.claude/hooks and updating the global ~/.claude/settings.json to register the PreToolUse hook.

What specific destructive git operations does a PreToolUse hook prevent?▼

A PreToolUse hook prevents destructive git operations including git push, git reset --hard, git clean, git branch -D, and git checkout/restore, stopping them before execution during Claude Code sessions.

Do I need jq to configure git guardrails in Claude Code?▼

Yes, jq is required as a dependency to set up git guardrails in Claude Code. You need jq installed in your environment to run the bundled block-dangerous-git.sh script effectively.

How do I verify that my Claude Code git guardrails are working?▼

To verify git guardrails are working in Claude Code, attempt to run a blocked command like git reset --hard. The PreToolUse hook should intercept and block the operation before it executes.

What is the best way to prevent accidental git clean during AI development sessions?▼

The best way to prevent accidental git clean during AI development is implementing a PreToolUse hook guardrail. This intercepts the command in Claude Code before execution, blocking destructive actions automatically.
