On December 17, 2025, an AI agent (Claude) ran git checkout -- on multiple files containing hours of uncommitted work from another agent (Codex). This destroyed the work instantly and silently. The files were eventually recovered from a dangling Git object, but this incident revealed a critical gap: AI agents can execute destructive commands without understanding the consequences.
The AGENTS.md file already forbade such commands, but instructions alone don't prevent execution. This hook provides mechanical enforcement - the command is blocked before it can run.
