Event hooks run automatically when something important finishes, without relying on chat to remember a follow-up.Examples: after a tool succeeds, after a record is created or updated, after a form is submitted, or after a scheduled job completes. A hook can notify someone or run another tool.A common pattern is welcoming new end users: when someone is invited or registers, a hook can create their profile row, set defaults, or send a welcome email. Those follow-ups should be safe to retry; if a hook fails, the invite itself still stands.Find them under App Blueprint → Event Hooks.
