What events can I trigger hooks with in Claude Code?

Claude Code supports several events including SessionStart, SessionEnd, PreToolUse, PostToolUse, UserPromptSubmit, and Stop.

How do I make my hooks work across different machines?

The Hook Creator uses the ${CLAUDE_PLUGIN_ROOT} environment variable in configurations to ensure paths remain relative to the plugin directory.

What is the difference between command and validation hooks?

Command hooks execute shell scripts or commands to perform actions, while validation hooks are specifically designed to check the state of files or the project.

Can I trigger a hook only for specific file edits?

Yes, by using the 'matcher' property, you can filter hooks to only trigger when specific tools (like Write or Edit) are invoked by Claude.

About

The Hook Creator skill enables developers to build responsive, event-driven behaviors within Claude Code plugins by automating the setup of hooks. By defining triggers for specific lifecycle events—such as SessionStart, PostToolUse, or UserPromptSubmit—this skill streamlines repetitive tasks like auto-formatting code, running test suites after edits, or initializing custom environment notifications. It provides structured guidance on hooks.json configuration, including precise tool matchers and the correct usage of environment variables like CLAUDE_PLUGIN_ROOT to ensure portable and robust automation.
