Meet BookWorm - a reading companion agent built with the new Think SDK from Cloudflare Agents. Think is an opinionated base class that gives your agents superpowers: persistent session memory, dynamic code generation, user-built extensions, background fibers, and more.
In this demo, I'll show you how BookWorm keeps track of my books across conversations, learns what I like, and even lets me build custom extensions on the fly. You'll see the new Session API in action, watch me generate a "Motivation Station" extension dynamically, and explore how fibers enable long-running background tasks.
Think is experimental and ready for you to explore. If you've been wanting to build agents that remember, adapt, and grow with your users—this is for you.
