Claude Code introduces function hooks as Claude Mods
A new feature called Function Hooks, referred to as Claude Mods, allows developers to extend the capabilities of Claude Code. This update introduces the ability to run small, custom shell scripts at specific, fixed moments during the application's lifecycle, such as right before a tool is executed or immediately after a session completes.
Adding lifecycle hooks to Claude Code represents a major shift from a rigid AI assistant to a highly customizable developer platform, potentially creating a vibrant ecosystem of shareable extensions. "Before tool" hooks allow developers to implement custom safety checks, logging, or input validation before Claude takes an action. "After session" hooks can be leveraged to automate repetitive tasks like code formatting, committing changes, or generating run summaries. The use of simple shell scripts lowers the barrier to entry, making it easy for developers to integrate Claude Code with their existing local tools and workflows.
