git-guardrails-claude-code

To prevent destructive git commands in Claude Code, you can use a PreToolUse bash hook that intercepts and validates command strings against a blacklist of high-risk operations before they reach the shell.

A bash hook intercepts dangerous git operations by validating command strings against a predefined blacklist before execution. It parses JSON command data using jq to check for high-risk actions like hard resets or force pushes.

Yes, you need jq installed to block git force pushes using this approach. The validation logic relies on jq for parsing JSON command data within the standard bash shell environment to execute the intercepting hook.

You can configure git safety guardrails for both global and project-specific installations. This flexible scope allows you to protect individual repositories or apply the destructive command blocking across your entire local environment.

High-risk git operations that should be blocked during AI-assisted coding include force pushes and hard resets. Blocking these destructive operations protects your repository from irreversible data loss caused by accidental execution.
