The Claude Hook Developer skill empowers developers to build sophisticated, event-driven extensions for Claude Code. It provides a comprehensive framework for implementing both prompt-based hooks for context-aware reasoning and command-based hooks for deterministic shell execution. By mastering lifecycle events such as PreToolUse, SessionStart, and Stop, users can enforce security policies, automate environment setup, and create custom validation gates. This skill ensures your plugin architecture follows best practices for portability, security, and performance, distinguishing between plugin-specific and user-level configuration formats.
