What are Claude Code hooks?

Hooks are event-driven scripts or LLM prompts that execute in response to specific events within the Claude Code CLI environment, such as tool usage or session starts.

Can hooks block actions?

Yes, 'Pre' events like PreToolUse or UserPromptSubmit can return a 'block' decision to prevent a specific command from executing based on custom logic.

How do I debug my hooks?

Run Claude Code with the 'claude --debug' flag to see which hooks are matching, the execution output of commands, and detailed error logs.

Where are hook configurations stored?

Hooks can be configured at the project level in .claude/hooks.json or at the user level in ~/.claude/hooks.json for global automation.

What is the difference between command and prompt hooks?

Command hooks execute standard shell scripts for logging or external tools, while prompt hooks use the LLM to make complex, context-aware decisions using natural language.

Automates and customizes Claude Code behavior through event-driven shell commands and LLM-powered prompt hooks.

Acerca de

The create-hooks skill provides comprehensive guidance for implementing event-driven automation within Claude Code. It enables developers to configure custom triggers for tool usage, session events, and user interactions, allowing for advanced workflows such as automated code formatting, safety checks for destructive commands, desktop notifications, and project-specific context injection. By leveraging both shell commands and LLM-evaluated prompts, this skill empowers users to build a personalized, efficient, and secure development environment without modifying the core Claude Code application.
