How do I ensure my hooks work across different user machines?

You should always use the ${CLAUDE_PLUGIN_ROOT} environment variable to reference files within your plugin directory to ensure portability regardless of the installation path.

Can hooks modify the behavior of Claude's tools?

Yes, specifically PreToolUse hooks can use the exit_modify method to change tool inputs before they are executed, allowing for automated parameter adjustment.

What is a Claude Code hook?

A hook is a specialized script or prompt that intercepts specific events in the Claude Code lifecycle, allowing you to validate, modify, or block operations before or after they occur.

When should I use a Command hook versus a Prompt hook?

Command hooks are best for deterministic, fast, and script-based checks like regex validation. Prompt hooks are ideal for context-aware decisions that require LLM reasoning.

Streamlines the creation of Claude Code hooks for intercepting, validating, and modifying lifecycle events within the development environment.

Acerca de

The Claude Code Hook Architect skill provides a comprehensive framework for developers to extend Claude Code's capabilities through custom plugins. It offers deep technical guidance on implementing Command, Prompt, and Agent-based hooks, allowing for the interception of lifecycle events like PreToolUse and SessionStart. By providing standardized templates and security-first implementation patterns, this skill ensures that developers can build robust safety guards, automated formatters, and custom validation logic that is both performant and portable across different project environments.
