SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Developers need reliable guidance and resources to create, configure, and secure event‑driven hooks for Claude Code plugins, ensuring safe tool usage and automated workflows.

Core Features & Use Cases

  • Comprehensive Hook Documentation: Detailed explanations of hook events, configuration formats, and matcher patterns.
  • Prompt‑Based and Command Hooks: Templates for both LLM‑driven validation and fast deterministic scripts.
  • Utility Scripts & Linters: Tools to validate hook schemas, test hooks, and enforce best‑practice coding standards.
  • Use Case Example: Quickly add a PreToolUse prompt hook that validates file writes before the tool executes, or a SessionStart command hook that loads project context automatically.

Quick Start

Ask the assistant to generate a PreToolUse hook that validates file write operations using a prompt‑based hook.

FAQPage Schema
How do I create Claude Code hooks for event-driven automation?

Prompt-based hooks use LLM-driven validation for complex logic, while command hooks execute fast deterministic scripts. Both formats apply to Claude Code events like PreToolUse and SessionStart, with templates provided for validation, testing, and deployment.

How do I validate file writes before tool execution in Claude Code?

Validating file writes before tool execution requires a PreToolUse hook. You can generate a prompt-based PreToolUse hook template to intercept and validate file write operations before the tool runs.

Do I need jq installed to manage Claude Code plugin hooks?

Yes, jq is a required dependency to manage Claude Code plugin hooks. The utility scripts use jq to validate hook schemas, test hooks, and enforce best-practice coding standards.

How do I load project context automatically when a Claude Code session starts?

Loading project context automatically requires a SessionStart command hook. This event-driven hook executes deterministic scripts upon session initialization to load context and orchestrate workflows.

What is the best way to enforce security and validation in Claude Code plugins?

Enforcing security in Claude Code plugins is best achieved by configuring event-driven hooks for PreToolUse and PostToolUse. The skill provides utility scripts and linters to validate schemas and enforce best-practice coding standards.

How do I test and validate Claude Code hook schemas?

Testing and validating Claude Code hook schemas is handled by provided utility scripts and linters. These tools enforce best-practice coding standards and validate configurations before deployment.
