SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Hook Development provides a structured approach to creating and managing Claude Code hooks that validate tool usage, enforce policies, and automate workflows, reducing risk and manual labor.

Core Features & Use Cases

Event-driven hooks for PreToolUse, PostToolUse, SessionStart, Stop, SubagentStop, etc., enabling validation, response, and context loading.
Supports both prompt-based and command-based hooks; uses hooks.json at plugin level or settings.json to configure behavior; includes guidance for integrating with scripts under scripts/, references/, assets/ as needed.
Real-world use: automatically block dangerous tool calls, log results, load project context on session start, and coordinate across events to maintain policy compliance.

Quick Start

Configure hooks.json and place scripts under scripts/ to define and enforce your Claude Code hooks.

FAQPage Schema

How do I create Claude Code hooks to validate and block dangerous tool calls?▼

Claude Code hooks validate tool usage by defining event-driven configurations in hooks.json. You can use PreToolUse events to automatically block dangerous tool calls and enforce safety policies during automation pipelines.

Can I use Claude Code hooks to load project context automatically on session start?▼

Yes, Claude Code hooks support SessionStart events to load project context automatically. You configure these event-driven hooks in hooks.json or settings.json to automate context loading when a session begins.

What events are supported when defining event-driven hooks for Claude Code?▼

Claude Code hooks support PreToolUse, PostToolUse, SessionStart, Stop, SubagentStop, SessionEnd, PreCompact, and Notification events. These events enable validation, response, and context loading across plugin workflows.

Do I need jq to configure Claude Code hooks?▼

Yes, jq is required as a dependency for Hook Development. You need jq installed in your environment to process JSON data and execute command-based hooks within your automation pipelines.

How do I set up prompt-based and command-based hooks for Claude Code?▼

Prompt-based and command-based hooks are configured by defining behavior in hooks.json or settings.json. You place executable scripts under the scripts/ directory and reference them within the configuration to enforce policies.

Why use Claude Code hooks instead of manual validation for plugin development workflows?▼

Claude Code hooks provide a structured approach to enforce policies and automate workflows, reducing manual labor and risk. They coordinate across events to maintain compliance automatically, unlike manual validation which is error-prone.
