How the Grok Bot harness works - @gabefletcher
The Grok Bot host builds model requests, runs tools and saves the agent's state. Hosted services also handle identity, scheduling, sync and other features.
A message starts in the desktop app. The desktop sends it to the box host and shows the response. It also manages account connections and can run tools on the user's computer. The host builds the model's context, calls the provider, runs requested tools and saves the results. It then decides whether another model call is needed. The visible chat, model conversation and learned memory use separate stores. Changing the model provider leaves the other hosted service calls in place.
The original architecture sections cover public host 17e335e and desktop 0.52. The later comparison adds five-host source analysis, desktop .57.1 findings and isolated runtime measurements. Host and desktop have separate version number
