One bad agent command can erase a working tree in seconds. dcg (Destructive Command Guard) is a command hook for AI coding agents that blocks destructive shell and Git commands before they execute. It helps you put an approval boundary around risky agent actions by intercepting commands, explaining why they were blocked, and suggesting safer alternatives. Key features: • Pre-execution guard – blocks risky Git and filesystem commands before they run • Agent integrations – supports hooks for Claude Code, Codex CLI, Gemini CLI, GitHub Copilot CLI, Cursor, Hermes Agent, and more • Configurable
