What you'll learn

Map any agent to four rungs you can engineer

Prompt, context, harness, loop: see what each one controls, and why you climb them in order.

See what actually makes an agent reliable

Watch a real agent stop smartly, use your own data, trace every step, and reconcile a team of sub-agents.

Take the map to your own agent

Leave able to place any agent you'd build — research, ops, policy — on the same four rungs.

Why this topic matters

Anyone can get an impressive demo from an LLM. Turning one into an agent you can actually rely on comes down to four engineering decisions: its prompt, its context, its harness, and the loop it runs in. In 30 minutes I'll climb all four on a real forecasting agent that researches live questions and scores its own calls — then show you the same map builds any agent, far beyond markets.
