SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Automating and governing Claude Code tool usage with reliable, event-driven hooks that enforce policies and reduce risk.

Core Features & Use Cases

Supports both prompt-based and command-based hooks for events like PreToolUse, PostToolUse, Stop, and SessionStart.
Provides templates and patterns for context loading, validation, logging, and risk scoring across projects.
Enables safe extension via optional directories (scripts/, references/, assets/) and ensures hooks run in parallel for performance.

Quick Start

Create a prompt-based PreToolUse hook to analyze tool_input and block dangerous operations.

FAQPage Schema

How do I create Claude Code hooks to validate PreToolUse and PostToolUse events?▼

Claude Code hooks validate PreToolUse and PostToolUse events by applying structured configurations to analyze tool_input, enforce policies, and block dangerous operations. You can create prompt-based or command-based hooks to automate safety checks and reduce risk.

What is the best way to secure plugin automation with event-driven hooks in Claude Code?▼

Securing plugin automation with event-driven hooks requires enforcing validation, risk scoring, and environment variable handling. This approach guards events like SessionStart and Stop, ensuring safe extension via optional directories while running hooks in parallel for performance.

Do I need jq installed to build and run command-based Claude Code hooks?▼

Yes, you need jq installed to build and run command-based Claude Code hooks. The hook development process depends on jq for parsing environment variables and structured tool_input data during event validation and context loading.

Can I run multiple Claude Code hooks in parallel for performance during plugin development?▼

Yes, you can run multiple Claude Code hooks in parallel for performance during plugin development. The hook configuration enforces parallel execution across events such as SubagentStop, ensuring automated validation and context loading do not bottleneck the workflow.

What are the limitations of prompt-based hooks for context loading in Claude Code?▼

Limitations of prompt-based hooks for context loading involve managing environment variable handling and debugging complexity. While prompt-based hooks analyze tool_input effectively, command-based hooks using jq are sometimes required for structured validation and performance.
