Hook Development

It covers the five main hook types: PreToolUse for validating operations before they run, PostToolUse for reacting to results, Stop and SubagentStop for enforcing completion standards, and SessionStart for loading project context. The guide emphasizes prompt-based hooks over function-based ones, which makes sense since you get LLM-driven decision making instead of hard-coded logic.
