Check - BeforeTool command firewall, 152 failures → 1

[golproductions]

Already works as a Gemini CLI BeforeTool hook. Validates every shell command before execution. Tested on a real production session: 152 command failures without validation, 1 with it. Deterministic, sub-100ms, no LLM in the validation path.

Hey there. Thanks for sharing this.

This is a really interesting idea and something we have been discussing internally. We love seeing how the community is pushing the boundaries of the CLI.

We will definitely keep this in mind for future iterations.
