Common App 的活动列表是整份申请里信息密度最高的地方：50 个字符写职位，150 个字符写描述，十条封顶。中文流水账压进去之后，多数人的问题不是写得不好，是**超限被系统截断**——而截断通常发生在句子中间，最后半句直接消失，读起来像没写完。 所以字符数必须由代码量。模型很会说「已压到 150 字符内」然后给你一条 187 字符的描述——这个 app 的代码活就在出口：逐条实测职位与描述的字符数，同时标出哪几条没有数字、哪几条不是动词开头。 再加上四个在 150 字符里塞进最多信息的具体办法（删冠词代词、分号串联、箭头代替 to、删掉自我评价），以及排序策略——第一条决定了后面还会不会被认真读。 还有一条反直觉的：**列超过十条时，削减本身是最有价值的一步**。深度一致的列表比广度分散的更容易让人记住你。$2 解锁逐条压缩改写（中译英 + 压到限内 + 补数字）、十条排序方案、以及动词与量化词的可选清单。The activities list is the densest part of a Common App application: fifty characters for the position, a hundred and fifty for the description, ten slots. After compressing a Chinese narrative into that, most people's problem isn't the writing — it's **truncation**, which happens mid-sentence and simply removes the second half. So the counting has to happen in code. A model will happily claim it fit in 150 characters and hand you 187. This tool's work is at the output: measuring every position and description, and flagging which entries have no number and which don't open with a verb. Plus four concrete techniques for fitting more into 150 characters — drop articles and pronouns, chain with semicolons, use arrows instead of "to", cut self-assessment — and an ordering strategy, since the first entry decides whether the rest gets read carefully. And one counter-intuitive point: **when you have more than ten, the cutting is the most valuable step**. A list with consistent depth is remembered; a broad scattered one isn't. $2 unlocks per-entry rewrites (translated, compressed to fit, with quantification), an ordering plan, and verb and metric word banks.
逐条压缩改写（中译英、压到限内、把「组织了活动」补成带数字的版本，改写后由代码复量）+ 十条的排序方案与理由 + 动词与量化词可选清单 + 该删哪几条的具体判断。Per-entry rewrites — translated, compressed to fit, quantified where possible, and re-measured in code afterwards — plus an ordering plan with reasoning, verb and metric word banks, and which entries to cut.
字符上限按 Common App 常见口径（职位 50、描述 150、十条）计算，不同申请系统、不同年份与不同栏目的限制可能不同——请以你实际填写的表单显示的计数为准，提交前在系统里核对一次。本工具只做字符计数与结构提示，不代表任何学校的评估标准，也不预测录取结果。请勿在活动列表中夸大职位、虚构规模或编造成果——这一栏经常在面试或校友面谈中被追问，也可能被推荐信内容交叉印证。你填写的内容不入库。Limits follow the common Common App convention (50 for position, 150 for description, ten entries); other systems, years and fields differ — rely on the counter in the form you're actually filling and verify before submitting. This counts characters and flags structure; it represents no school's criteria and predicts no outcome. Never inflate a title, invent scale or fabricate outcomes — this section is frequently probed in interviews and can be cross-checked against recommendations. Nothing you enter is stored.
