Tailor Gemini CLI to your workflow with hooks

Summary

The article introduces Gemini CLI hooks, a feature that allows developers to customize the behavior of the Gemini CLI without modifying its source code. Hooks act as middleware, enabling users to inject context, validate actions, enforce security policies, and log tool usage. The article provides a practical example of using hooks for automated secret scanning, detailing the implementation of a script that blocks sensitive data from being written to the codebase. Best practices for using hooks are also discussed, emphasizing performance and security considerations.
