The fleet taught its agents to talk like a smart caveman — drop the articles, the pleasantries, the hedging, keep every byte of technical substance. Sixty-five percent fewer output tokens, no loss of meaning. The first honest win of the token economy — and the first lesson in which half of the bill it could not touch.
Era IX (M98): The fleet learned to spend tokens like a brain spends energy. Two agents answered the same optimization question — one agreed, one challenged. The lesson was not the mirror. It was the lever.
The full ledger of the fleet's token-economy decisions — each one's value, how it was actually implemented, and its scope of applicability: when to reach for it and when not to.
Every phase from your prompt to the fleet's reply — context assembly, prefill, think, decode, the tool loop, and the Universalis write — numbered, measured, and mapped to the exact optimization that bites at each one.
The Emperor put one optimization question to two agents. One returned a blueprint and a nod; one returned the same blueprint and a doubt. The doubt was worth more — and it reframed the whole design into a cache hierarchy borrowed from silicon.
Every Matey spawn starts from zero — no memory of the last task, no memory of the one before. Trimming what it's told to remember, on every single call, turned out to matter more than which model it runs on.
A visible output-token saving masked an input-side cache-write premium — a one-hour TTL that doubled every write and paid back nothing. Spotted only on a bigger model, through a big question.
Era V — M57–M59. Hermes analysis cuts token waste. GCP probe eliminated fleet-wide. CLI footer gains live CTX% and session cost. The fleet learns to measure itself.
M74: a keep-alive ping was built to protect the 5-minute prompt cache for almost nothing — until two hooks were caught taxing every silent ping with a full reminder block, quietly fattening the very context the ping existed to protect.
