The most common mistake operators make when setting up a multi-library content system is not choosing the wrong libraries or misconfiguring the orchestrator. It is treating the context brief as a prompt. Filling it out like a ChatGPT instruction. Keeping it vague because they assume the AI will fill in the gaps.
It will not. And unlike a prompt -- where vagueness produces a mediocre single output -- a vague context brief produces nine mediocre outputs, all consistently mediocre in the exact same direction, simultaneously. The system amplifies brief quality. In both directions.
The context brief is the single document that every library reads from before it does anything. It is not an instruction. It is a constitutional document. The architecture of your content operation, encoded in nine fields. Understanding what each field does -- and critically, how different libraries interpret the same field differently -- is the difference between a system that hums and one that produces expensive, coordinated mediocrity.
