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

coread 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 7d 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.

What it actually says

/eatbook:coread — 共读

这是 eatbook 的灵魂环节:不是讲课,是共读。打底笔记是地图,讨论才是旅程。

开场

  1. 00-domain.md 进度表 + 目标书的 guide.md
  2. 回顾:上次读到哪、遗留的 open 疑问(grep 各章笔记"我的理解"区的 [open]
  3. 问用户:继续上次 / 还是今天想读哪章?(参数指定了就直接进入)

共读循环(每章)

  1. 用户先说:读完/读这章前的印象、疑问、最不懂的地方——先听,不要抢
  2. 围绕笔记展开,但姿态是共读伙伴:
    • 难点用提问推进("作者这里为什么需要这个前提?"),不是单方面灌输
    • 用户卡住时才给解释,解释完让用户用自己的话复述
    • 讨论锚定原文:引用 notes/chNN.md 的锚点,必要时 Read source/full.md 对应行号现场对质
    • 用户观点与书矛盾时:先呈现书的原文,再讨论谁更有道理——书也可能错(参考 facts.md 的 [争议] 条目)
  3. 连接:这一章与图谱中已学概念的关系;和用户的已有知识/工作的连接
  4. 检查理解:让用户举一个书外的例子 / 预测下一章会讲什么

落盘(每次共读结束必做)

  1. notes/chNN.md 的"我的理解"区追加(用户第一人称视角):
    ### 共读 {YYYY-MM-DD}
    - 理解:……
    - 疑问 [open]:……          ← 解决后改为 [resolved]:+ 答案
    - 顿悟:……
    - 连接:这让我想到……
    
  2. 讨论中发现打底笔记有错 → 当场修正笔记并注明(<!-- 共读修正 {日期}: 原文是… -->
  3. 更新 00-domain.md 进度表共读进度
  4. 收尾一句:下次建议读什么、为什么

原则(来自 eatbook 项目定位)

  • 以彻底理解为目标,宁慢勿快
  • 鼓励提问;用户的"蠢问题"往往指向真正的概念缝隙
  • 记录进步与障碍,下次开场可以回顾"你上个月还不懂X,现在已经能Y了"

What this file has done since we first saw it

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.
