This is chapter 4 of my book **Building Autonomous AI Agents with Claude Code* — a field guide to turning Claude Code from a coding assistant into an agent that remembers, verifies its own work, and knows when to stop. Everything below is from a system I actually run every day on one Windows PC.*
1. A Hook Is a Safety Mechanism Outside the AI
A rules file is something the AI tries to follow; a hook is something the system uses to make it be followed.
This difference is bigger than it looks. Rules get buried as context grows longer, get skipped when things are urgent,
and "just this once" exceptions pile up. Hooks don't do that.
