SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jq, timeout, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers create reliable event-driven automation for Claude Code plugins by providing guidance for validating actions, enforcing workflows, and integrating custom hook behavior without guesswork.

Core Features & Use Cases

Hook Implementation Guidance: Create and configure PreToolUse, PostToolUse, Stop, SessionStart, and other Claude Code hooks with appropriate event handling.
Security and Validation Patterns: Design safer command hooks and prompt-based hooks for checking tool usage, protecting sensitive files, and enforcing development standards.
Use Case: A plugin developer can use this Skill to add a PreToolUse validation workflow that reviews risky commands before execution and reports clear decisions.

Quick Start

Use the hook development skill to help me create a Claude Code plugin hook that validates dangerous tool operations.

Frequently Asked Questions about Hook Development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I build Claude Code hooks to validate tool usage before execution?▼

You build Claude Code hooks for tool validation by configuring a PreToolUse event hook that intercepts risky commands, applies validation rules, and reports decisions before execution proceeds. This Skill provides patterns for implementing these event-driven workflows safely.

What are event-driven hooks in Claude Code plugin development?▼

Event-driven hooks in Claude Code are automation triggers that fire during specific lifecycle events like PreToolUse, PostToolUse, SessionStart, or Stop. They allow plugins to enforce workflows, run security checks, and validate actions automatically.

Can I use command and prompt-based hooks together for security checks in Claude Code?▼

Yes, you can use command and prompt-based hooks together for Claude Code security checks. This Skill guides you through designing safer hook patterns that protect sensitive files and enforce development standards across both implementations.

Do I need jq and timeout installed to configure Claude Code automation hooks?▼

Yes, you need jq and timeout installed to configure reliable Claude Code automation hooks. These dependencies support parsing validation outputs and enforcing time limits on hook processing for safer plugin integration.

What's the best way to automate session lifecycle events in Claude Code plugins?▼

The best way to automate session lifecycle events in Claude Code plugins is implementing SessionStart and Stop hooks with event-driven validation. This Skill provides configuration guidance for applying these patterns to enforce workflows and integrate custom behavior reliably.

Why should I add validation workflows to Claude Code hooks?▼

You should add validation workflows to Claude Code hooks to prevent risky tool operations and protect sensitive files during automated sessions. Implementing PreToolUse security checks ensures commands are reviewed and clear decisions are reported before execution.
