Give us an hour and we’ll give you a working agentic web app prototype. We’ll assemble a minimal chat UI, define tool-calling agents, and deploy to the cloud, narrating how AI pair programming speeds up the connective tissue so you can focus on design and behavior. Expect practical patterns for function calling, context strategy, and streaming responses, plus a clear view of what’s demo‑safe versus production‑ready. It’s a fast, honest look at building with AI in the loop, what works, what breaks, and how to ship a compelling prototype without pretending it’s ready for scale.
