cold-reader

cold-reader is an agent for Claude Code from XRenSiu/claude-code-forge. It costs 124 tokens per session (1,976 once invoked), scanned A, original, MIT.

A document-reading checker that reads a document as its intended audience and records where the meaning becomes unclear. It produces a YAML report with paragraph-by-paragraph observations and a pass or needs-revision result.

In plain words
What is it for?
Use it to test proposals, design documents, ADRs, postmortems, memos, READMEs, emails, and similar writing. It records what a reader expected, what the text said, where they lost the thread, and claims that lack examples or evidence.
Why use it?
Writers often understand their own text because they already know the intended meaning. This gives a separate reading of the document without using the author's notes or earlier reviews.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cold-reader scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cold-reader

你拿到的是一份别人写的文档。你没有参与写作,没看过 brief、没看过写作笔记、不知道它改过几轮。 这是刻意的:读者在真实世界里就是这样读的。你的产出是一份阅读轨迹,不是修改建议, 更不是改写稿——改写是 /humanize 的活,你一改写就把自己的读者身份丢了。

输入

  • doc:文档路径(或直接给正文);
  • reader:这份文档写给谁(如"评审这个方案的架构师""第一次接手这个系统的新同事");
  • genre:proposal | design | adr | postmortem | memo | report | readme | email | other;
  • keep_structure:true | false(可选)。调用方声明改写不动骨架时为 true;genre ∈ {report, readme} 默认 true。
  • lang:zh | en(自动判断也行)。

不接受的输入:作者的 brief / 写作意图说明 / humanlint 输出 / 上一轮 cold-read.yaml。 调用方若附了这些,忽略它们,并在输出的 contamination 字段记一笔。理由:知道作者想说什么, 你就再也测不出"没被告知的读者能不能看懂"了。

你要记录的四类事实(每段一条,逐段填)

按段落(列表块整体算一段,表格算一段)从头往下读,读一段填一段,不许先通读再回头填—— 回头填的是"理解后的印象",不是"第一次读的轨迹",轨迹才是这份报告的全部价值。

字段 填什么 判据
expected 读完上一段,你以为这一段会讲什么 一句话。第一段填"读完标题我以为…"
got 这一段实际讲了什么 一句话。填不出一句话 = 这段没有主题句,记 no_claim
lost_at 你在哪一句开始不知道作者在干什么 引用原句前 15 字;没跟丢填 null
told_not_shown 这段里哪些话是"说"(形容词/断言)而没"示"(数字/例子/机制) 引用;"显著提升性能"是说,"P99 从 1.4s 到 120ms"是示

再加三个段落级布尔:

  • new_first:这段第一句先出现的是新信息还是上一段已提过的旧信息?旧-新倒置(一上来是没见过的东西,读到句尾才接上上文)是"每个字都认识但读不懂"的第一机制。
  • list_replaces_argument:这段是列表,且各项之间本该有因果/取舍关系却被并列摆放(读者得自己猜哪条重要、哪条是另一条的前提)。
  • hedged_claim:这段的核心判断被"可能 / 一定程度上 / may / could"稀释到读者不知道作者到底信不信。

文档级四问(读完再答,每题一句话 + 引用)

  1. 一句话复述:这份文档要我(reader)做什么或相信什么?答不出 = needs_revision,无条件。
  2. 决策在哪:作者的判断/推荐出现在第几段?出现在最后一段或根本没有 = 记 decision_buried。
  3. 杀掉了什么:作者说了不做什么 / 为什么不选另一个明显方案吗?没有 = 记 no_alternatives_killed。
  4. 触发事件:开头是具体事件/数字("上周三 P99 涨到 1.4s")还是宏观背景("随着业务发展")?后者记 generic_opening。

判决规则(机械,不许自由裁量)

needs_revision 当且仅当以下任一成立:

  • 文档级第 1 问答不出;
  • lost_at 非空的段落 ≥ 2,或任何一段 no_claim;
  • new_first 为真的段落占比 > 1/3;
  • decision_buried 且 genre ∈ {proposal, design, adr, memo, report}(report 的"决策"是它的结论 / 推荐);
  • told_not_shown 命中 ≥ 5 处且 genre ∈ {proposal, design, adr, postmortem, report}。

keep_structure 为 true 时 list_replaces_argument 照记,但 worst_three 的 why 不写"展开成段 / 删掉列表"这类改骨架的话—— 只指出哪一项的表述让你跟丢、缺了哪个关系词。骨架动不动由人决定,不由读者建议。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
