a commander spawned a classification agent on Opus, spent $0.26 deciding
which of three folders a transcript belonged in, noticed, and said it would
pin Haiku instead. it was right and nothing had told it — the model rule
lives in the delegating skill, which is about the platform's own agents.
so it is in the template now: haiku for anything mechanical and repeated,
sonnet where there is real judgement, opus almost never — and if a spawned
agent seems to need opus, the rules in CLASSIFICATION.md are too vague and
sharpening them is cheaper than paying for the same decision every time.
with the reason it matters more here than anywhere: a commander fires once
per item, forever. the difference between models is not one decision, it is
one decision multiplied by however long the owner keeps using it.
