SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This skill addresses the complexity of extending Claude Code by providing a standardized, secure, and efficient framework for implementing event-driven hooks that validate, automate, and enhance agent behavior.

Core Features & Use Cases

  • Event-Driven Automation: Execute custom logic in response to lifecycle events like PreToolUse, SessionStart, and Stop.
  • Hybrid Validation: Combine deterministic bash-based command hooks with intelligent, context-aware prompt-based hooks.
  • Use Case: Implement a security guardrail that automatically blocks unauthorized file system access or enforces mandatory test execution before an agent is allowed to stop a task.

Quick Start

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

FAQPage Schema
How do I build event-driven hooks for Claude Code plugins?

Claude Code hooks are built using a framework that supports event-driven automation for lifecycle events like PreToolUse and SessionStart, enabling custom logic execution and agent behavior validation.

Can I use both bash commands and LLM prompts for tool validation in Claude Code?

Yes, hybrid validation combines deterministic bash command hooks with context-aware LLM prompt-based validation to enforce tool usage rules and session lifecycle management in Claude Code.

How do I add security guardrails to block unauthorized file access in Claude Code?

You can add security guardrails by implementing PreToolUse hooks that validate file write operations, automatically blocking unauthorized file system access before agent tool execution.

Do I need jq installed to develop Claude Code hooks?

Yes, jq is a required dependency for running the utility scripts that handle configuration schemas and validation logic within the Claude Code hook development framework.

What is the best way to enforce mandatory test execution before a Claude Code agent stops?

The best way to enforce test execution is by configuring Stop lifecycle event hooks that validate test completion, preventing the agent from stopping until mandatory tests pass.

Why use standardized configuration schemas for Claude Code plugin hooks?

Standardized schemas ensure Claude Code plugin hooks remain secure, portable, and performant across different environments while maintaining consistent event-driven behavior.
