README

Excerpt

Hook Development for Claude Code Plugins

Overview

Hooks are event-driven automation scripts that execute in response to Claude Code events. Use hooks to validate operations, enforce policies, add context, and integrate external tools into workflows.

Key capabilities:

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

Hook Types

Prompt-Based Hooks (Recommended)

Use LLM-driven decision making for context-aware validation:

{
  "type": "prompt",
  "prompt": "Evaluate if this tool use is appropriate: $TOOL_INPUT",
  "timeout": 30
}

This is the opening of the README. Read the full README on GitHub.
