Automates workflows and enforces safety policies by creating event-driven hooks for Claude Code operations.
Claude Hook Authoring empowers developers to extend and secure Claude Code by implementing event-driven logic throughout the development lifecycle. It enables the creation of both complex LLM-powered prompt hooks and deterministic command hooks to validate tool inputs, automate formatting, and manage session context. Whether you're enforcing security policies to block dangerous commands or setting up auto-formatters like Biome or Prettier, this skill provides the standardized patterns and implementation guidance necessary to build robust, reactive agent workflows.
