SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

The Hook Development skill empowers teams to design, validate, and implement event-driven Claude Code hooks for plugins, reducing manual QA and ensuring policy compliance.

Core Features & Use Cases

  • Design and implement PreToolUse, PostToolUse, Stop, SessionStart, and other hook events
  • Provide a mix of prompt-based and command-based hooks with best practices
  • Use references to validate and test hooks, and leverage scripts for automation
  • Real-world example: enforce safety checks before tool use and log outcomes for audit

Quick Start

Configure and wire a starter set of hooks into your Claude Code plugin, then run tests to verify correct operation.

Frequently Asked Questions about hook-development

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

FAQPage Schema
How do I implement Claude Code plugin hooks for event-driven automation?▼

Implement Claude Code plugin hooks by configuring a hooks.json file to define PreToolUse, PostToolUse, Stop, and SessionStart events. This skill provides references and scripts to design deterministic checks and LLM-assisted reasoning for secure, event-driven tool and policy automation.

What are PreToolUse and PostToolUse hooks used for in Claude Code?▼

PreToolUse and PostToolUse hooks execute deterministic safety checks before tools run and log outcomes for audit after execution. They enforce policy compliance and reduce manual QA by validating event-driven automation within Claude Code plugins.

How do I validate and test Claude Code hooks before deploying them?▼

Validate and test Claude Code hooks using the scripts directory utilities provided by this skill. Run automated tests against your hooks.json configuration to verify correct operation of PreToolUse, PostToolUse, Stop, and SessionStart event triggers.

Do I need jq installed to develop Claude Code hooks with this skill?▼

Yes, jq is a required dependency for the hook-development skill. You need jq installed in your environment to run the validation scripts and process JSON payloads for Claude Code hook automation and testing.

Can I use command-based and prompt-based hooks together in a Claude Code plugin?▼

Yes, you can mix command-based and prompt-based hooks in a single Claude Code plugin. This skill provides best practices for combining both hook types to achieve deterministic checks and LLM-assisted reasoning across your automation workflows.

What is the best way to enforce safety checks before tool use in Claude Code?▼

The best way to enforce safety checks is configuring PreToolUse hooks in your hooks.json file. This intercepts tool execution for deterministic policy validation and logs audit outcomes, ensuring secure event-driven automation across projects.
