Building Hooks is a specialized skill for Claude Code that enables developers to create, modify, and manage event-driven automations. By leveraging lifecycle events like session starts, tool invocations, and user prompts, this skill allows for automated validation, formatting, logging, and security policy enforcement. Whether you need to block dangerous bash commands, auto-format code after a write operation, or initialize environment variables at startup, Building Hooks provides the structure and schema validation necessary to build robust, reliable Claude Code plugins and local configurations.
