Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.00868 |
| Opus 5 | $0.00028 | $0.00434 |
| Sonnet 5 | $0.00011 | $0.00174 |
| Haiku 4.5 | $0.00006 | $0.00087 |
Grade A, and why
open-book-layered-index 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 12d 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
Open-Book Layered Index
开卷考试复习索引。输出分层检索结构，将知识点映射至课件文件名与页码；默认不包含知识点解释性正文。
Applicability
- 开卷考试复习资料编制
- 需快速定位：某主题对应哪份 PDF、哪几页
- 输入为全套 lecture PDF/PPT；可选历年试题目录用于附录权重表
Design Principles
- 覆盖完整优先于篇幅压缩
- 知识结构优先于课件原始页序
- 索引职责与解释职责分离：本 skill 仅负责索引
- 图示、UML、流程图、表格须转写为可检索文字条目，不得使用「见图」类占位表述
Output Contract
默认输出 revision_exam.md，推荐结构：
# <Course> Open-Book Index
## Layer 1 — Course Blocks
Mermaid 概览：Block → 课件文件列表
## Layer 2 — Per-Lecture Index Tables
### <PDF filename>
| Topic（缩写首次附全称） | Pages |
|--------|-------|
## Layer 3 — Figure / Diagram Index（可选）
| Figure / Diagram | PDF | Pages | Related topics |
## Appendix — Exam Topic Pointers（可选，需 oldResource）
| Topic | Frequency | Priority | PDF | Pages |
英方课程：英文术语及缩写首次出现须附全称。
Workflow
1. Corpus ingestion
读取全部 PDF/PPT，同时处理：
- 正文、图片、UML、架构图、时序图、状态图、活动图、表格、公式
- 图中箭头、标注及其逻辑关系
对每张关键图示提取：核心概念、组成单元、单元关系、说明的问题、关联知识点。
2. Layer 1 — Course blocks
按主题将课程划分为若干 Block；每 Block 映射一组课件文件。输出 Mermaid 分层概览。
3. Layer 2 — Lecture index tables
对每份 PDF 生成完整「Topic → Pages」表。页码为 PDF 内页序；若课件含 printed slide number，可同时标注。
4. Layer 3 — Figure index
汇总关键图表索引，支持考场按图名检索。
5. Appendix — Exam pointers（可选）
若提供 @oldResource：
- 统计历年试题考点频率
- 输出单一 Master Table，合并频率、优先级与页码指向
- 不得重复生成多张同义排序表
Constraints
- 页码必须对应工作区中真实文件名
- Layer 2 须覆盖全部课件，不得遗漏章节
- 缩写首次出现须含全称
- 合并或删除旧版中间文件前须经用户确认
Examples
使用 open-book-layered-index：@lectureSlides 生成 revision_exam.md。Layer 1–3 为分层索引，不包含知识点解释。
使用 open-book-layered-index，结合 @oldResource 在 Appendix 中追加考点频率与页码指向表。

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 108 lines · 56 tokens per session scan A cba969a06542
open-book-layered-index is a skill published in the GitHub repository wvov7/course-revision-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 868 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
