SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Hook Development provides a structured framework for building and managing Claude Code hooks that enforce policies, validate tool usage, and automate workflows across projects and teams.

Core Features & Use Cases

  • Support for both prompt-based and command hooks across multiple events (PreToolUse, PostToolUse, Stop, SessionStart, etc.) to enable flexible, context-aware validation.
  • Guidance on hook configuration, best practices, testing, and debugging to ensure reliability and safety in production environments.
  • Real-world use cases include blocking dangerous tool calls, loading project context at session start, logging hook activity, and coordinating cross-event workflows.

Quick Start

Create a Claude Code plugin with a hooks.json that defines at least one PreToolUse hook and one Stop hook, then implement a prompt-based hook to assess a tool call.

Frequently Asked Questions about Hook Development

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

FAQPage Schema
How do I create Claude Code hooks to validate tool usage and enforce policies?▼

Claude Code hooks validate tool usage and enforce policies by defining structured configurations in hooks.json. You build prompt-based or command hooks across events like PreToolUse and PostToolUse to block dangerous tool calls and automate workflows.

What events can I use to trigger Claude Code hooks for automation?▼

Claude Code hooks support multiple trigger events including PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, and SessionEnd. These events enable flexible, context-aware validation and coordinated cross-event workflow automation.

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

Prompt-based hooks assess tool calls using prompts, while command hooks execute specified scripts. Both hook types are configured in hooks.json to enforce policies and validate usage across different session and tool events.

How do I configure Claude Code hooks to run safely in production environments?▼

Configuring Claude Code hooks safely requires using portable paths like ${CLAUDE_PLUGIN_ROOT} in commands and structuring configurations in hooks.json. Following best practices for robust input validation and testing ensures reliable production automation.

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

Claude Code hooks can load project context automatically using the SessionStart event. By configuring a hook in hooks.json, you run commands or prompts that initialize workflows and coordinate cross-event automation when a session begins.
