To block destructive commands before execution, you can use a Claude Code hook that intercepts dangerous CLI inputs like `rm -rf` or `git push --force` and prevents them from running, safeguarding against data loss.

The best way to prevent AI agents from running dangerous terminal commands is to configure a pre-execution blocking hook that intercepts inputs, applies sub-millisecond filtering, and stops execution with a clear explanation.

Yes, you can configure which specific commands are blocked using modular security packs, allowing granular control over terminal protection rules for different areas like git, databases, Kubernetes, and cloud platforms.

Command blocking does not slow down terminal performance because the filtering uses SIMD acceleration and Aho-Corasick algorithms to achieve sub-millisecond latency during command interception.

To set up guardrails for `git reset --hard`, configure a Claude Code hook that intercepts the command before execution, utilizing security packs designed to block destructive git operations and prevent accidental data destruction.

You need a pre-execution hook to protect your filesystem when AI agents or automated processes have terminal access, risking accidental data loss from destructive commands like `rm -rf /` or forced git operations.
