How the brain works
Agents start light and look up what they need.
When you pay for AI by usage, the provider earns more the more tokens you burn. Fleet earns a flat USD 19 a month and nothing on your AI usage, so our incentive runs the other way: get the job done with less. That is why the brain is minimalist. Short lesson records, small briefs and on-demand lookups keep the model's context clear, so you spend fewer tokens on reading and more on the work.
Most AI setups start every session by loading a wiki: old handoff notes, long rules files, last week's chats. That uses up the model's focus before it does any work, and half of it is out of date.
Fleet keeps what your team learns as lesson records. Each one is four short lines: when it applies, what to do, why, and an id. Never more than 60 words.
An agent starts with a short brief for one task. When its work touches something a lesson names, it looks that lesson up. Nothing else comes along.
Not every lesson makes the cut. Fleet ranks lessons by how closely they match the task and hands the model only the top few. The librarian keeps the set lean: it merges duplicates, retires lessons that are wrong or out of date, and writes down why, so the model's attention goes to the knowledge that matters most. You can see what each lesson is doing for you, and undo any change.
