# Config conduit lifecycle hooks

**🟡 Intermediate · Lesson 33**

SpellbookConfiguration hooks, family 2: the CONDUIT LIFECYCLE. Five moments of a conduit's life are observable: on_conduit_pre_created / on_conduit_post_created / on_conduit_activated at conjure, and on_conduit_cleanup_start / on_conduit_cleanup_complete at the end. Register before conjure; watch the whole life.
