SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill enables developers to integrate event-driven functionality into their plugins by defining and managing hooks that trigger specific actions based on predefined events.

Core Features & Use Cases

  • Event-Driven Actions: Define custom actions that execute automatically when specific events occur within the Claude environment (e.g., SessionStart, PreToolUse).
  • Configuration Management: Learn how to configure hooks using hooks.json to specify event triggers, matching patterns, and command executions.
  • Script Integration: Understand how to write Python scripts that handle hook events and integrate them into the plugin's execution flow.
  • Use Case: Automatically log detailed information about tool usage before each tool is executed by configuring a PreToolUse hook to run a custom logging script.

Quick Start

Configure a SessionStart hook to execute a Python script located at ./scripts/on_session_start.py.

FAQPage Schema
How do I add event-driven hooks to trigger actions on session start and end?

Event-driven hooks trigger custom actions by configuring `hooks.json` with specific lifecycle events like `SessionStart` and `SessionEnd`, mapping them to Python scripts for reactive plugin behavior. You define matching patterns and command executions tied to those event types.

What is the best way to configure a PreToolUse hook for logging tool usage?

Configuring a `PreToolUse` hook for logging requires defining the event trigger and matching pattern in `hooks.json`, then pointing the command execution to a custom Python script. This script handles the event and records detailed tool usage information before execution.

How does Python script integration work with plugin hook configurations?

Python script integration works by mapping event triggers defined in `hooks.json` to executable Python files. The scripts handle hook events and integrate into the plugin execution flow, allowing custom command executions tied to specific event patterns like `PreToolUse`.

Can I use custom matching patterns to trigger specific hook commands?

Yes, you can use custom matching patterns to trigger specific hook commands. Configuration management through `hooks.json` allows you to specify event triggers, define matching patterns, and set command executions for precise reactive plugin behavior.

Do I need any external dependencies to develop event-driven plugin hooks?

No external dependencies are required to develop event-driven plugin hooks. The Skill provides references and scripts to facilitate hook development using `hooks.json` configuration and Python script integration without additional libraries.
