SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a structured approach to designing and implementing Claude Code plugin hooks, enabling developers to enforce validation, automate workflows, and safely integrate tools across events.

Core Features & Use Cases

  • Supports prompt-based hooks for flexible, context-aware decision making.
  • Supports command hooks for fast, deterministic checks and external tool integration.
  • Covers a full lifecycle of events (SessionStart, PreToolUse, PostToolUse, Stop, SessionEnd) with best practices for safe, scalable hook implementations.

Quick Start

Describe how to implement a minimal prompt-based PreToolUse hook and validate it end-to-end using the test-hook tooling.

FAQPage Schema
How do I validate tool usage in Claude Code using hooks?▼

You can validate tool usage in Claude Code by implementing PreToolUse hooks. This skill helps you design prompt-based or command-based hooks to enforce deterministic checks and safely validate tool executions across diverse plugin projects.

What is the difference between prompt-based and command hooks in Claude Code plugins?▼

Prompt-based hooks enable flexible, context-aware decision making, while command hooks execute fast, deterministic checks and integrate with external tools. This skill provides patterns for safely implementing both types across your plugin lifecycle.

How do I automate event-driven workflows across a Claude Code session?▼

Automate event-driven workflows by configuring hooks for lifecycle events like SessionStart, PostToolUse, and SessionEnd. This skill establishes safe, scalable patterns to trigger automated validations and actions throughout your entire Claude Code session.

Can I use Claude Code hooks for external tool integration and automated checks?▼

Yes, command hooks support fast, deterministic checks and external tool integration. This skill provides implementation patterns to safely connect external tools and automate validation workflows within your Claude Code plugin architecture.

What are the best practices for safely building scalable Claude Code plugin hooks?▼

Best practices for scalable Claude Code plugin hooks include using prompt-based hooks for context-aware decisions and command hooks for deterministic validation. This skill enforces safety patterns across all lifecycle events to ensure robust, scalable implementations.
