Hooks System

Version: 1.0.0 Purpose: Lifecycle hook patterns for validation, automation, security, and metrics in Claude Code workflows Status: Production Ready

Overview

Hooks are lifecycle callbacks that execute at specific points in the Claude Code workflow. They enable:

• Validation (block dangerous operations before execution)
• Automation (auto-format code after file changes)
• Security (enforce safety policies on commands and tools)
• Metrics (track tool usage, performance, costs)
• Quality Control (run tests after implementation changes)
• Context Injection (load project-specific context at session start)

Hooks transform Claude Code from a reactive assistant into a proactive, policy-enforced development environment.
