Membership lesson · Build Your Jarvis · Module 6 — Agent core

The loop — Jarvis picks the tool

The agent arrives. core/agent/ gets the loop — given a job, the model reads the registry, decides which tool it needs (or that it needs none), the app runs it, the result comes back, and round it goes for multi-step jobs — a date from the clock feeding a sum in the calculator feeding the answer. Built with its honest guardrails from breath one — a step limit the loop cannot blow through, a stop button that kills a run dead, and a step trail in the chat showing every decision, call and result while it happens and after. Plain questions still get plain answers with no tool theatre. The member designs the trail and working signal in their own words; the loop runs one tool call at a time on purpose.
