Provides comprehensive implementation patterns and event-driven automation guidance for Claude Code hooks.
The Hooks Reference Skill is a specialized documentation and implementation guide designed to help developers master Claude Code's event-driven hook system. It provides detailed technical specifications for lifecycle events—ranging from tool validation with PreToolUse to session initialization with SessionStart—enabling users to build production-grade automations. By leveraging this skill, developers can implement robust security checks, automate project context loading, and enforce custom workflow rules that transform Claude into a highly controlled and efficient autonomous development agent.
