Claude Fable 5.1 can write dense prose. Sentences may run long, paragraphs may contain too many ideas, and figurative phrases may replace literal statements.Claude Fable 5.1 可能会写出文风繁密的文字。句子可能过长，段落可能包含过多意思，比喻性短语也可能取代直白的表述。
Anthropic provides a specific instruction for this problem.Anthropic 针对这个问题提供了特定指令。
The core prompt核心提示词
Write a short message (about 120 words) to customers of a budgeting app. Explain that the next version will import bank statements automatically, what changes for them, and how to keep entering expenses by hand.
Follow the following instructions when writing:
Mannered prose substitutes metaphor and flourish for direct statement. Instead of "a parameter worth varying," the mannered writer produces "a dial worth turning." Instead of "this point still matters," they write "this point earns its keep." The phrases exist to display the writer, not to convey the idea, and readers can tell. That is why mannered prose irritates: it makes the reader work harder so the writer can perform. It is also imprecise. Metaphors drag in connotations the writer did not choose and cannot control. The fix is to say what you mean. When a literal phrase is available, use it.
The second paragraph in the prompt above is the style instruction. It defines mannered prose, gives two examples, explains the cost to the reader, and states how to revise it. The model can apply those tests to each sentence.上面提示词中的第二段就是风格指令。它定义了矫饰文风，举出两个例子，说明了这种文风给读者造成的理解成本，并说明如何改写。模型可以把这些测试应用到每个句子上。
“Be concise” only states a goal. It does not identify the phrases to remove or explain what should replace them. Anthropic also suggests the shorter instruction, “Please remove all mannered prose,” when the full paragraph is unnecessary. See Prompting Claude Fable 5.1: Writing density.“要简洁”只陈述了一个目标，并没有指出要删除哪些短语，也没有说明该用什么来代替。当不需要整段完整风格指令时，Anthropic 还建议使用更短的指令：“请移除所有矫饰文风”。另请参阅 Prompting Claude Fable 5.1: Writing density。
A worked edit一个实际编辑示例
Consider this sentence:看看这个句子：
Automatic imports give your budget a clearer runway, while manual entry remains a path you can continue to walk.自动导入为你的预算提供了更清晰的跑道，而手动录入仍然是一条你可以继续走的路。
“Runway” and “path” do not add information. Replace them with literal statements:“跑道”和“路”并没有增加信息。把它们换成直白的说法：
Automatic imports can save you time. You can still enter every expense by hand if you prefer.自动导入可以帮你节省时间；如果你愿意，仍可手动录入每一笔开支。
The revision states what the feature does and confirms that manual entry remains available. The prompt does not require every sentence to be short. It requires each phrase to add information.改写后的版本说明了该功能的作用，并确认手动录入仍然可用。提示词并不要求每个句子都简短，而是要求每个短语都增加信息。
