What problem does it solve?

This Skill streamlines the creation of Claude Code hooks, enabling automated tool validation, workflow enhancements, and proactive security checks. It eliminates manual intervention for repetitive tasks and ensures compliance, allowing you to focus on core development.

Core Features & Use Cases

• Event-Driven Automation: Create hooks that trigger on specific events like PreToolUse, PostToolUse, UserPromptSubmit, and SessionStart to automate actions at critical points.
• Tool Validation & Blocking: Implement scripts to validate bash commands, prevent access to sensitive files, or auto-approve safe operations, enhancing security and control.
• Contextual Enhancements: Automatically add relevant context to prompts or set up environment variables at session start, improving Claude's effectiveness and reducing manual setup.
• Use Case: Create a PreToolUse hook that validates all Bash commands to prevent dangerous operations like rm -rf /, and a PostToolUse hook that auto-formats Python files after Write or Edit operations.

Quick Start
