Hooked Model

If you're building features that need repeat engagement without constant marketing nudges, this walks you through Nir Eyal's Hooked Model: the trigger, action, variable reward, investment cycle that makes products feel automatic. It's the framework behind why you check Instagram when you're bored or open Slack when you're anxious. The skill helps you identify internal triggers worth owning and design loops that genuinely improve user lives rather than just extract attention. Best for consumer products where retention matters more than acquisition. Skip it if your product is inherently infrequent or requires conscious evaluation each time.
