SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Hooks provide event-driven automation for Claude Code plugins, enabling validation, policy enforcement, and context loading to streamline safe tool use.

Core Features & Use Cases

  • Validate tool calls before execution (PreToolUse)
  • React to tool results (PostToolUse)
  • Enforce completion standards (Stop, SubagentStop)
  • Load project context (SessionStart)
  • Automate workflows across the development lifecycle
  • Supports Prompt-Based and Command Hooks, plus plugin/settings formats

Quick Start

Create a new hook by editing SKILL.md and add corresponding scripts in scripts/, then restart Claude Code to load the updated hooks and test with claude --debug.

Frequently Asked Questions about hook-development

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

FAQPage Schema
How do I automate tool validation in Claude Code using event-driven hooks?▼

Event-driven Claude Code hooks automate tool validation by intercepting PreToolUse and PostToolUse events. You configure validation rules in SKILL.md, add corresponding scripts in the scripts/ directory, and restart Claude Code to load the updated hooks.

What is the difference between PreToolUse and PostToolUse hooks for plugin workflows?▼

PreToolUse hooks validate tool calls before execution to enforce policy, while PostToolUse hooks react to tool results after execution. Both event-driven hook types enable automation and context loading within Claude Code plugin workflows.

Can I use Claude Code hooks to load project context on SessionStart?▼

Yes, SessionStart hooks enable event-driven context loading when a Claude Code session begins. You define the hook in SKILL.md, place the loading scripts in scripts/, and restart Claude Code to apply the automated context injection.

What's the best way to enforce completion standards with SubagentStop and Stop hooks?▼

Stop and SubagentStop hooks enforce completion standards by intercepting session termination events in Claude Code. You implement validation scripts in the scripts/ directory, register them in SKILL.md, and restart to activate the event-driven policy enforcement.

Do I need to restart Claude Code for new plugin hooks to take effect?▼

Yes, you must restart Claude Code after editing SKILL.md and adding scripts to load updated hooks. You can then test the event-driven automation and validation behavior using the claude --debug command to ensure proper hook execution.

Claude Code hooks not working after editing SKILL.md, how do I debug them?▼

Debug Claude Code hooks by running claude --debug to inspect event-driven hook execution and validation errors. Ensure scripts are correctly placed in the scripts/ directory and restart Claude Code to load the updated plugin configuration.
