SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill empowers you to automate complex workflows within Claude Code by leveraging event-driven hooks, ensuring robust validation, context management, and seamless integration.

Core Features & Use Cases

  • Event-Driven Automation: Trigger custom logic on events like tool use, session start/end, or user prompts.
  • Advanced Validation: Implement sophisticated checks for tool calls, file operations, and command execution using prompt-based or command-based hooks.
  • Context Management: Load project context, persist environment variables, and manage session state effectively.
  • Use Case: Automatically validate that all code changes are accompanied by unit tests before allowing the agent to stop the session, preventing incomplete work.

Quick Start

Use the hook-development skill to create a PreToolUse hook that validates file write operations for security.

FAQPage Schema
How do I automate workflows in Claude Code using hooks?▼

Claude Code hooks automate workflows by triggering custom logic on events like tool use or session start. You implement these event-driven hooks using configuration formats like plugin hooks.json or settings files.

What is a PreToolUse hook and how does it validate file operations?▼

A PreToolUse hook triggers custom logic before a tool executes, enabling advanced validation for file write operations and command execution. It uses matchers to target specific tools and ensure security checks pass.

How do I configure matchers for Claude Code event hooks?▼

You configure matchers within plugin hooks.json or settings files to target specific events for your command or prompt-based hooks. This ensures your event-driven automation triggers precisely on the intended tool calls.

Can I use prompt-based hooks to prevent an agent from stopping a session?▼

Yes, prompt-based hooks can evaluate session state on the Stop event to prevent incomplete work. You can automatically validate that code changes have accompanying unit tests before allowing the agent to stop.

What are the security and performance considerations for plugin development?▼

Plugin development requires following security best practices for command execution and applying performance considerations to prevent hook latency. Proper debugging techniques are also essential to maintain efficient event-driven automation.
