Hook Development

Acerca de

Enhances your ability to create and implement Claude Code plugin hooks, which are event-driven scripts that execute in response to specific workflow events. This skill provides comprehensive guidance on using hooks to validate operations, enforce policies, add context, and integrate external tools. It covers both simple command-based hooks for deterministic checks and advanced, LLM-driven prompt-based hooks for powerful, context-aware logic. Use this skill to build robust, secure, and highly customized automations within the Claude Code environment.

Características Principales

• Explains hook configuration formats for both plugins and user settings
• Details environment variables like ${CLAUDE_PLUGIN_ROOT} for building portable scripts
• Implements event-driven automation using hooks (PreToolUse, PostToolUse, SessionStart, etc.)
• 4 GitHub stars
• Provides security best practices for writing safe hooks, including input validation and path safety
• Guides creation of both command-based and advanced prompt-based hooks for context-aware validation

Casos de Uso

• Automating project setup by loading context or environment variables when a new session starts.
• Validating tool usage before execution, such as blocking dangerous file writes or shell commands.
• Enforcing task completion criteria or coding standards before allowing Claude to finish a task.
