  • Works in 3 steps: 插入文档:gen_diagram 生成后,在 feishu_doc_create… → 交互式大图表:单文件 HTML,图表自己用内联 SVG / canvas… → 图表下方补一行数据来源/口径说明
  • Tasks that involve Diagrams
  • SKILL.md covers 铁律:画图用 gen_diagram,不要手写 SVG, 选型(按图的内容选 kind), echarts 模板要点 and dot(架构图)要点, plus 3 more sections
  • Calls curl; reaches cdn.jsdelivr.net

What it does

Data Viz is an agent skill from CatCatUncle/openworkbuddy. 数据可视化与画图——流程图/架构图/时序图/数据图表,用 gendiagram 工具一键渲染成 SVG+PNG,或生成交互式 ECharts 页面

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Diagrams. It works with Mermaid. The repository describes itself as: Open-source Claude Cowork / Codex alternative — a local-first AI office agent that turns one request into real PPTX, DOCX, XLSX and HTML files. Runs DeepSeek, Qwen, Doubao…

When your agent uses it

  • Tasks that involve Diagrams

Example prompts

  • “/data-viz”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 插入文档:gen_diagram 生成后,在 feishu_doc_create 的 markdown 里独占一行写 图说明 即真插图;Word/PPT 也用 PNG
  2. 交互式大图表:单文件 HTML,图表自己用内联 SVG / canvas 画,不引 CDN。
  3. 图表下方补一行数据来源/口径说明

What it can do on your machine

Read from SKILL.md and the folder at commit b960479. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • cdn.jsdelivr.net

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Data Viz loads about 494 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 122 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~494

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 122 words (~494 tokens).

“手写 SVG 坐标全靠脑算,一画就崩。gen_diagram 是真渲染器(ECharts/Graphviz/mermaid/PlantUML), 输出 <名字>.svg + <名字>.png(PNG 直接可插飞书/Word/PPT)。”
