Why is the ${CLAUDE_PLUGIN_ROOT} variable important?

It ensures that your hook paths remain stable and portable across different environments, preventing broken references when the plugin is installed.

What types of hooks can I implement with this skill?

You can implement command-based hooks, prompt-level interceptions, and agent-specific lifecycle hooks using standardized templates.

How does this skill help with hook validation?

It provides automated validation scripts and smoke tests to ensure your hooks.json structure is correct and your handler scripts are properly formatted and executable.

What are Claude Code hooks?

Hooks are specialized scripts that trigger during specific events in the Claude Code lifecycle, allowing developers to automate actions during commands, prompts, or agent workflows.
