I read every Claude Code hook so you don’t have to

This article provides an in-depth analysis of all 27 Claude Code hook events, focusing on the most useful ones like PreToolUse, UserPromptSubmit, PostToolUse, and SessionStart. It explains how hooks work with JSON stdin/stdout, and offers practical examples such as secret redaction, command blocking, and dynamic context injection. The author shares real-world usage patterns from building AI DevKit, emphasizing how hooks can enforce rules around coding agents instead of relying on model memory. A technical guide for developers using AI coding tools.
