📖 Effort — Control how many tokens Claude uses（Anthropic Claude Platform Docs）

✍️ 句式拆解：

“Effort is a behavioral signal, not a strict token budget.”

🔍 结构：

• 主句主干：Effort is a behavioral signal（主语 + 系动词 + 主语补足语），用 is 给出概念的定义性陈述
• 否定同位成分：, not a strict token budget — 逗号后接 not + 名词短语，与前面的 a behavioral signal 形成平行对仗（都是”不定冠词 + 形容词 + 名词”结构），通过否定来精确划定概念边界

💡 亮点：这是技术写作里”先立后破、正反界定”的经典手法。作者用一个 not 把读者最容易混淆的两个概念（行为信号 vs 严格预算）一次性区分开——既说清了 effort「是什么」，又排除了「它是硬性上限」的误解。节奏上，behavioral signal 与 strict token budget 音节数相近，构成工整的平行结构，读起来有收束感，是下定义的黄金句式。相比「Effort is not a strict token budget; it is a behavioral signal」这种先否定后肯定的写法，先肯定再否定更简洁、更自信。

🧩 段落精读：

“By default, Claude uses high effort, spending as many tokens as needed for excellent results. You can raise the effort level to max for the absolute highest capability, or lower it to be more conservative with token usage, optimizing for speed and cost while accepting some reduction in capability. Effort is a behavioral signal, not a strict token budget. At lower effort levels, Claude will still think on sufficiently difficult problems, but it will think less than it would at higher effort levels for the same problem.”

🔗 逻辑：论点 → 论证 → 定性 → 补充

• 抛出默认行为（论点）：第一句点明默认值 high，并用现在分词短语 spending as many tokens as needed 解释其含义
• 展开可调范围（论证）：第二句用 raise ... to max / lower it 两个对仗动作勾勒出完整的调节区间，optimizing ... while accepting ... 点明「收益」与「代价」并存
• 给出精确定义（定性）：第三句用 not a strict token budget 一锤定音，纠正「effort = 硬预算」的误读
• 用反例佐证（补充）：第四句用 but 转折，说明低 effort 下遇到难题「仍会思考、只是更少」，坐实「行为信号」而非「严格预算」的判断

📌 连接词：or（并列选择）· while（让步/伴随）· not（否定界定）· but（转折）
