Hook Development

Helps you build event-driven automation for Claude Code using hooks that trigger on tool use, session events, and stop conditions. The real value is in the prompt-based hooks API, which lets you use LLM reasoning to validate tool calls or enforce policies instead of writing brittle bash scripts. You can block dangerous file writes, verify task completion before stopping, or inject project context on session start. The documentation clearly separates the plugin hooks.json format (which needs a wrapper object) from the settings format (which doesn't), something easy to mess up. If you're building plugins or want to add guardrails to your workflow, this covers the full hook lifecycle with practical examples for each event type.
