What are Claude Code hooks?

Hooks are event-driven scripts that trigger during specific lifecycle events of Claude Code commands, prompts, or agents to modify behavior or automate tasks.

How does this skill help with hook validation?

It provides specialized utility scripts for smoke testing and deterministic validation of your hooks/hooks.json configuration to prevent runtime errors.

Where should hook files be placed?

The skill manages hook placement within the hooks/ directory of your plugin and uses the ${CLAUDE_PLUGIN_ROOT} variable for stable pathing.

Can I use templates for hook scripts?

Yes, the skill provides standardized templates for command, prompt, and agent hook examples to help you jumpstart development.

Does this support agent-specific workflows?

Yes, it is designed to handle sophisticated hook configurations for agent prompt interception and multi-step agentic behavior coordination.

Productivity & Workflow

Simplifies the creation and validation of Claude Code hook configurations and scripts for custom agentic workflows.

This skill enables developers to architect sophisticated event-driven behaviors within Claude Code plugins by automating the setup and maintenance of hook configurations. It provides structured guidance on identifying hook events, matchers, and types, ensuring that scripts are properly implemented, executable, and validated. Whether you are building command-specific triggers or complex agent prompt hooks, this skill ensures deterministic integration and robust error checking through progressive disclosure of configuration rules and ready-to-use script templates.
