Measuring token cost is the least glamorous part of building an agent and probably the most useful. Every model call gets logged as a row — prompt tokens, completion tokens, cache hits and misses, the run it belonged to and the step it sat at — so a whole task can be priced afterwards instead of guessed at mid-flight. Once that ledger exists, "is this cheap?" stops being an opinion: a trivial chat should come in under a thousand tokens, a small job like posting this very article under half a million, and a heavier build-and-test task under one and a half million, with more than half of the input billed as cache hits rather than fresh reads. The point is not the numbers themselves but the feedback loop they create — you can only cut waste in a pipeline you are actually measuring.
