Not a lab — a read, and worth repeating even if you've heard some of it before. The same opening the live core session starts with, then three words you'll hear constantly and should be able to define precisely: agentic, agent, context.
Done
Model, tools, context. Nothing else in the box.
Every impressive thing an agent has done in front of you — including in this very seminar — decomposes into those three ingredients and nothing more. A stateless regression predicting tokens. A set of functions it's allowed to call, each one a request/response round trip exactly like the curl calls earlier in this track. And a context window someone deliberately filled with the right instructions, history, and results. When something an agent does looks like magic, it's worth the five seconds to ask which of the three is actually doing the work — because one of them always is, and it's never "the model got smarter."
