SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve? AI coding assistants can execute destructive git commands like git push --force, git reset --hard, or git clean -fd that permanently destroy work or overwrite remote history. This Skill prevents that by installing a hook that intercepts and blocks these commands before they run. ## Core Features & Use Cases - Pre-execution Blocking: Registers a PreToolUse hook that intercepts Bash tool calls and blocks git push, git reset --hard, git clean -f/-fd, git branch -D, git checkout ., and git restore .. - Flexible Scope: Install the guardrail for a single project (.claude/settings.json) or globally across all projects (~/.claude/settings.json). - Customizable Patterns: Edit the bundled shell script to add or remove blocked command patterns to match your team's safety policy. - Use Case: A developer lets Claude Code run autonomously on a repository but wants to guarantee it can never force-push to main or wipe uncommitted changes during a session. ## Quick Start Ask Claude to set up git guardrails that block dangerous git commands like push and reset --hard for this project.

Frequently Asked Questions about git-guardrails-claude-code

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

FAQPage Schema
How do I block dangerous git commands in Claude Code?▼

Install a PreToolUse hook that matches the Bash tool and runs a script checking each command against dangerous patterns. When a command like git push or git reset --hard matches, the script exits with code 2 and Claude sees a blocked message.

Which git commands does this hook block?▼

The script blocks git push (including --force), git reset --hard, git clean -f and -fd, git branch -D, git checkout ., and git restore . by matching regex patterns against the command string.

Can I install git guardrails for all projects at once?▼

Yes, copy the hook script to ~/.claude/hooks/ and register it in ~/.claude/settings.json instead of the project-level file. The hook then applies to every Claude Code session regardless of project.

How do I add or remove blocked git command patterns?▼

Edit the DANGEROUS_PATTERNS array in the copied block-dangerous-git.sh script. Each entry is a grep -E compatible pattern, so you can add new commands or remove existing ones to fit your policy.

Why is the git guardrail hook not blocking commands?▼

Common causes are the script missing executable permission (run chmod +x), an incorrect path in settings.json, or jq not being installed since the script uses jq to parse the tool input JSON.
