Seatbelt for Claude Code

Four hooks that stop Claude Code from making the mistakes you only make once.

• Blocks destructive shell commands: rm -rf on / or ~, force push, reset --hard, git add -A, git commit -a, pkill -f, curl | sh, DROP from the shell.
• Refuses to write API keys (Anthropic, OpenAI, Stripe, AWS, GitHub, Supabase service role...) anywhere but .env.
• Stops dangerous SQL through MCP, including the three classic Supabase leaks: views readable by anon, SECURITY DEFINER functions, tables without RLS.
• Sends Claude back to check when it says "it's live" without having verified the deployment.

One-command install, one-command uninstall, 131 checks included. Python 3.9+ standard library only, nothing sent anywhere. macOS only for now.
