SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps you design Claude Code hooks that validate tool usage, enforce workflow rules, and automate responses to agent events without brittle manual intervention.

Core Features & Use Cases

  • Prompt-based validation for context-aware decisions on events like PreToolUse, Stop, SubagentStop, and UserPromptSubmit.
  • Command-based automation for deterministic checks, startup context loading, and portable execution using CLAUDE_PLUGIN_ROOT.
  • Use cases include blocking dangerous file operations, verifying completion before stopping, and loading project context at session start.

Quick Start

Ask for a Claude Code hook setup that validates Write and Edit actions with the right event matchers and safe output format.

Frequently Asked Questions about hook-development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate Claude Code tool execution before modifying files?▼

You can validate Claude Code tool execution by configuring PreToolUse hooks with prompt-based decisions and matcher-based targeting to block dangerous file operations. This approach requires structured JSON outputs to enforce safety-focused validation rules.

Can I use Claude Code hooks to load project context automatically at session start?▼

Yes, you can use SessionStart hooks to load project context automatically at session start. This command-based automation ensures portable execution using the CLAUDE_PLUGIN_ROOT environment variable for deterministic startup checks.

What is the best way to automate responses to Claude Code agent events?▼

The best way to automate Claude Code agent event responses is implementing event-driven hooks for PostToolUse, SubagentStop, and Stop workflows. These hooks apply prompt-based validation to verify completion and enforce workflow rules automatically.

Does hook-based validation work with UserPromptSubmit and PreCompact workflows?▼

Hook-based validation works with UserPromptSubmit and PreCompact workflows by applying prompt-based decisions to govern Claude Code execution. It supports matcher-based targeting and structured JSON outputs across all supported event types.

How do I ensure my Claude Code plugin hooks remain portable across environments?▼

To ensure Claude Code plugin hooks remain portable, use command-hook portability with CLAUDE_PLUGIN_ROOT for environment-agnostic execution. This allows scripts to reference plugin resources consistently across different configurations.
