mermaid-summarizer

mermaid-summarizer is a skill for Claude Code, Codex from Jacobinwwey/notemdpro. It costs 22 tokens per session (442 once invoked), scanned A, original, MIT.

A document summarizer that turns Markdown into a Mermaid mindmap, a text format for diagrams. It creates a hierarchy of topics, summaries, and key sentences, and can optionally translate the result.

In plain words
What is it for?
Use it to create visual summaries, outlines, study guides, and relationship maps from Markdown files, saving the generated Mermaid diagram to a file.
Why use it?
It makes a long document easier to study or understand by showing its structure and main ideas as a visual map.

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

mermaid-summarizer 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 23d 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

Mermaid summarizer

English

Read the complete authorized document and identify its core concepts and ownership hierarchy. Use a Mermaid mindmap for a genuine hierarchy; use diagram-generator when explicit cross-branch relations need a different diagram family.

Generate a single fenced Mermaid block with a mindmap declaration and consistent indentation. Parentheses are valid shape syntax: a root may be root(("Title")). Preserve labels and required concepts; do not delete punctuation or relationships merely to pass parsing. Track any deliberate summarization separately from syntax repair.

Validate with mermaid-healer. Keep the original output if an unknown family or ambiguous incomplete block needs review. Report source coverage and unresolved errors through workflow-runner. Successful Mermaid text generation does not prove that a host rendered or exported it.

中文

阅读完整的已授权文档,确定核心概念及归属层级。真正的层级适合 Mermaid mindmap;跨分支的显式关系需要其他图形类型时,使用 diagram-generator。

生成单个 Mermaid 围栏代码块,包含 mindmap 声明并使用一致缩进。圆括号是有效形状语法,根节点可以写作 root(("Title"))。保留标签及必要概念,不得为了通过解析而删除标点或关系。将有意的内容摘要与语法修复分别记录。

使用 mermaid-healer 验证。遇到未知类型或含义不明确的未闭合代码块时,保留原输出供审阅。通过 workflow-runner 报告来源覆盖和未解决错误。Mermaid 文本生成成功不代表宿主已完成渲染或导出。

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.
