output contract

In short

The rule that says what an agent may say when it is done: one line if something needs a human, nothing at all otherwise.

An agent that reports every step is noise. An agent that reports nothing is a risk. The output contract sits between: do the work silently, then say exactly one line if a human needs to act, and say nothing if not.

It is written at the top of every scheduled job. It keeps a phone quiet through a hundred successful runs and makes the one failure impossible to miss.

The contract also governs voice. The line that does get sent is delivered word for word, as the agent, so it has to be written the way the company speaks.

Example

What it looks like.

OUTPUT CONTRACT: do all the work first, without narrating. If everything published cleanly, reply exactly [SILENT]. Reply with one line only if something failed or needs a decision.
