A Practical Guide to Claude Code Hooks

Building upon the previous theoretical discussion, this article provides a hands-on walkthrough of registering and operating Hooks in Claude Code.

We will implement a basic Post-command Hook that automatically displays a notification message whenever the AI model modifies files within the project using the Edit or Write tools.

In addition, we take a detailed look at the updated usage of the /hooks slash command introduced in recent versions, as well as the process of manually registering hooks by defining Matcher and Command arrays directly within the project-scoped settings.json configuration file.
