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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00210 | $0.05921 |
| Opus 5 | $0.00105 | $0.02960 |
| Sonnet 5 | $0.00042 | $0.01184 |
| Haiku 4.5 | $0.00021 | $0.00592 |
Grade A, and why
html-line-svg 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.
How it starts
The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HTML 语义框线 SVG
把原内容中的对象、关系、状态与阅读顺序,重新编码为克制的技术文档式框线图。先保证图能准确复述教学判断,再处理构图与 SVG 细节;不要把原插图机械描摹成矢量轮廓。每次交付同时生成一份自包含的线框图提示词,使同一语义设计能够被复用、复核和继续迭代。
开始前
- 读取目标内容、相邻内容、现有图片或草图、承载它的 HTML/CSS 和可用空间。
- 在
course-design中工作时,读取根目录AGENTS.md、docs/design/STYLE_DNA.md、目标页面使用的设计 token 与更具体的目录规范。 - 由其他 skill 调用时,回到调用它的上层工作流:遵守上层 skill 规定的事实来源、源文件、素材登记、追溯记录、生成物和验证范围,不固定绑定
tailor-html-to-slide、ppt-like-html或任何单一载体。独立调用时,遵守目标项目与目标文件所在目录的规则。 - 保护原结论、概念边界、方向、状态与数量。无法从材料确认的关系不要画成箭头。
工作流
1. 写语义规格与可选 Mermaid 关系结构
在画图前写出一个最小规格;可放在工作笔记中,不要求成为最终页面文字。
teaching_claim: 这张图必须让读者看懂的一个判断
objects:
- id: object-a
label: 对象名称
role: interface | agent | task | container | document | state
relations:
- from: object-a
to: object-b
type: flow | dispatch | claim | sync | association | compare | contains
direction: forward | bidirectional | none
path: primary | alternative
payload: 可选;仅在理解交接物时填写
states:
- target: object-b
type: added-later | waiting | incomplete | fading | persistent | warning | blocked
visible_labels:
- text: 对读者可见的文字
role: group-title | object-label | relation-label | caption
layout_constraints:
peer_alignment: visual-center-y | top | baseline | none
alignment_tolerance: "0.5% of viewBox height"
minimum_safe_gap: "2% of viewBox width"
containment_label_zone: top | side | none
reading_order: left-to-right | top-to-bottom | center-out | board-to-peers
只保留支持 teaching_claim 的信息。名称、数量、箭头方向、实线或虚线都必须能在规格中找到语义理由。path 区分主流程与非主流程;payload 仅在不说明交接物就无法理解关系时填写,不要为每条箭头强行补产物。visible_labels 用来提前发现相邻层级的重复文字;layout_constraints 写相对约束,不写只适用于某一张图的坐标。
当图以节点关系为主时,优先在 YAML 之前或之后补一段 Mermaid,把它作为可执行、可预览的关系结构规格。系统架构、流程、Agent 协作、状态转换、时序交互、类关系和实体关系通常适合;GUI 页面线框、纯视觉对比和难以抽象为节点关系的插图可以省略。选择语法和写法时参考 Mermaid 官方图表语法文档,并从该页导航到 Flowchart、Architecture、Sequence、State、Class、Entity Relationship 等对应图型。
Mermaid 规格遵循以下要求:
- 使用稳定、可读的节点 ID;把必须展示的文字写成显式标签。
- 写清分组、关系动词、箭头方向和可确认的状态;材料没有依据的连接不要添加。
- 选择能表达语义的最小图型,不为展示 Mermaid 功能而增加节点形状、颜色或关系。
- 把 Mermaid 的节点、分组和边视为语义依据,不把自动布局、折线路径、坐标或默认样式视为最终设计。
- Mermaid 不能替代
teaching_claim、对象角色、状态歧义说明、可见标签、布局约束、阅读顺序和窄屏行为;仍用 YAML 或紧邻 Mermaid 的文字补齐这些信息。

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.

html-line-svg is a skill published in the GitHub repository simbajigege/book2skills (162 stars, last pushed 16d ago), licensed MIT. It adds 210 tokens to every session and 5,921 once invoked, about $0.0011 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 2026-08-30.
