What it does
Space Chart HTML is an agent skill from SpaceZephyr/design-buddy. 生成设计美观的图表 HTML 文件。支持 10 种图表类型：流程图、架构图、ER 图、商业模式画布、用户旅程图、思维导图、竞品分析图、SWOT 分析、产品路线图、组织架构图。支持 3 种内置视觉风格（黑白简约、深色暗调、Claude 暖色）+ 品牌风格扩展。 触发词："画个 XX 图"、"生成商业模式画布"、"做个架构图"、"画 ER 图"、"帮我画个流程图"、"生成用户旅程图"、"做个思维导图"、"竞品分析图"、"SWOT 分析图"、"产品路线图"、"组织架构图"、"商业模式画布"、"XX 风格的图表"、"帮我可视化"。 当用户提供了一段描述并要求可视化、画图、生成图表时使用。当用户要求切换图表风格时也触发。
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/chart-templates.md` and `references/style-presets.md`).
It sits in Business, Finance & HR, covering Startup and business strategy. It works with Notion. The repository describes itself as: Design Buddy: visual production Agent Skills for brand design systems, GPT-image-2 images, diagrams, infographics, logos, slide decks, WeChat layouts and social images.

What it can do on your machine
Read from SKILL.md and the folder at commit f1d835f. 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:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
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
Space Chart HTML loads about 1.5k tokens when it runs, and up to ~6.9k if it reads all its reference files. Until then it costs about 82 tokens; SKILL.md has 453 words of instructions outside code blocks.
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 453 words (~1,541 tokens).

- space-chart-html
Files
