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.

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 | $0.00076 | $0.02716 |
| Opus 5 | $0.00038 | $0.01358 |
| Sonnet 5 | $0.00015 | $0.00543 |
| Haiku 4.5 | $0.00008 | $0.00272 |
Grade A, and why
excalidraw-diagram 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.
This is a copy
100% identical to excalidraw-diagram — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excalidraw Diagram Generator
Create Excalidraw diagrams from text content, outputting Obsidian-ready .md files.
Workflow
- Analyze content - identify concepts, relationships, hierarchy
- Choose diagram type (see below)
- Generate Excalidraw JSON
- Generate Obsidian-ready
.mdfile with Excalidraw frontmatter - Automatically save to current working directory
- Notify user with file path and confirm save successful
Output Format

Diagram Types & Selection Guide
选择合适的图表形式，以提升理解力与视觉吸引力。
| 类型 | 英文 | 使用场景 | 做法 |
|---|---|---|---|
| 流程图 | Flowchart | 步骤说明、工作流程、任务执行顺序 | 用箭头连接各步骤，清晰表达流程走向 |
| 思维导图 | Mind Map | 概念发散、主题分类、灵感捕捉 | 以中心为核心向外发散，放射状结构 |
| 层级图 | Hierarchy | 组织结构、内容分级、系统拆解 | 自上而下或自左至右构建层级节点 |
| 关系图 | Relationship | 要素之间的影响、依赖、互动 | 图形间用连线表示关联，箭头与说明 |
| 对比图 | Comparison | 两种以上方案或观点的对照分析 | 左右两栏或表格形式，标明比较维度 |
| 时间线图 | Timeline | 事件发展、项目进度、模型演化 | 以时间为轴，标出关键时间点与事件 |
| 矩阵图 | Matrix | 双维度分类、任务优先级、定位 | 建立 X 与 Y 两个维度，坐标平面安置 |
| 自由布局 | Freeform | 内容零散、灵感记录、初步信息收集 | 无需结构限制，自由放置图块与箭头 |

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.
