Installs a Claude Code PreToolUse hook that stops destructive git commands before the shell runs them: force pushes, pushes to protected branches, reset --hard, clean -f, checkouts and restores that discard edits, stash clear and history rewrites, while risky but legitimate commands become a confirmation prompt. Use when someone says "stop Claude from pushing", "block git push --force", "protect main from Claude Code", "add git safety hooks", "Claude wiped my changes with reset --hard", or wants guardrails before running Claude Code in auto mode or with permissions bypassed.
