A high-performance hook for AI coding agents that blocks destructive commands before they execute, protecting your work from accidental deletion.

**Supported:** [Claude Code](https://claude.ai/code), [Gemini CLI](https://github.com/google-gemini/gemini-cli), [GitHub Copilot CLI](https://docs.github.com/en/copilot/concepts/agents/coding-agent/about-hooks), [Cursor IDE](https://cursor.com), [OpenCode](https://opencode.ai) (via [community plugin](https://github.com/aspiers/ai-config/blob/main/.config/opencode/plugins/dcg-guard.js)), [Aider](https://aider.chat/) (limited—git hooks only), [Continue](https://continue.dev) (detection only), [Codex CLI](https://github.com/openai/codex)

Quick Install

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/destructive_command_guard/main/install.sh?$(date +%s)" | bash -s -- --easy-mode

Works on Linux, macOS, and Windows (WSL). Auto-detects your platform and downloads the right binary.

TL;DR

**The Problem**: AI coding agents (Claude, GPT, etc.) occasionally run catastrophic commands like `git reset --hard`, `rm -rf ./src`, or `DROP TABLE users`—destroying hours of uncommitted work in seconds.

**The Solution**: dcg is a high-performance hook that intercepts destructive commands *before* they execute, blocking them with clear explanations and safer alternatives.
