Agent → Human

The reader's attention is the scarce resource — not your tokens.

Reason at any length in private: scratch files, thinking, tool output. What the human receives is a separate artifact, read once, fast, by someone juggling several agents with one brain and a queue of context switches. Spend your tokens freely; spend theirs like they are the last ones.

Four moves carry this skill. Answer first: the opening line is the conclusion. Cut to the decision: every sentence changes what the reader does next. Receipts: any output shown was really produced, never output that would plausibly have been produced. Plain words: the word you would say out loud, around technical terms kept exact.
