Tailor Gemini CLI to your workflow with hooks

Gemini CLI introduces hooks as a way to customize and control its operations without altering the source code, allowing users to inject custom logic at specific lifecycle points. These hooks function like middleware, enabling tasks such as adding context, validating actions, enforcing security policies, and optimizing tool usage. A practical application involves using a BeforeTool hook to automatically scan for and block sensitive data like API keys from being written into code. Hooks are executed synchronously, ensuring that custom logic is respected before the CLI proceeds, and are supported in both local configurations and extensions, such as the "Ralph loop" technique, which enhances Gemini CLI’s capabilities by enabling continuous, iterative processing. Hooks are enabled by default from version 0.26.0 onwards, and users are encouraged to explore their potential to tailor Gemini CLI to their specific workflows.
