SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill provides comprehensive guidance for creating and implementing Claude Code plugin hooks, focusing on advanced prompt-based hooks API for event-driven automation, tool use validation, and policy enforcement.

Core Features & Use Cases

Event-Driven Automation: Use hooks to trigger actions based on Claude Code events like PreToolUse, PostToolUse, Stop, etc.
Tool Use Validation: Validate tool use before execution to ensure compliance and security.
Prompt-Based Hooks: Leverage LLM-driven decision making for context-aware validation and flexible evaluation logic.
Advanced API: Support for custom matcher patterns, JSON configuration formats, and robust error handling.
Use Case: For a developer looking to implement a PreToolUse hook to validate code submissions and provide real-time feedback based on the submitted code.

Quick Start

Use the hook-development skill to create a PreToolUse hook to validate code submissions and provide real-time feedback.

FAQPage Schema

How do I create Claude Code plugin hooks for event-driven automation?▼

Claude Code plugin hooks trigger event-driven automation by configuring JSON files with custom matcher patterns to intercept events like PreToolUse and PostToolUse. This allows you to execute Python scripts for HTTP requests and JSON parsing to validate tool use.

Can I validate tool use before execution in Claude Code?▼

Yes, you can validate tool use before execution in Claude Code by implementing a PreToolUse hook. This event-driven mechanism intercepts tool calls to enforce compliance, validate code submissions, and provide real-time feedback before actions proceed.

What are prompt-based hooks in Claude Code and how do they work?▼

Prompt-based hooks in Claude Code leverage LLM-driven decision making for context-aware validation. They use an advanced API to evaluate flexible logic against event data, enabling dynamic policy enforcement rather than relying solely on static rules.

Do I need Python to implement advanced matcher patterns for Claude Code hooks?▼

You need Python to implement advanced Claude Code hooks if your automation logic requires HTTP requests or JSON parsing. The hook development process utilizes Python libraries like requests and json to process event data and execute validation scripts.

What is the best way to enforce policy compliance using Claude Code events?▼

The best way to enforce policy compliance using Claude Code events is by configuring prompt-based hooks with custom matcher patterns. This approach validates tool use dynamically and provides real-time feedback based on your specific security rules.
