What it does
Excalidraw Diagram is an agent skill from infometa/workbuddyskills. Create Excalidraw diagrams for workflows, architectures, protocols, concepts, and system explanations. Use when a user wants a flowchart, architecture sketch, visual explanation, or diagram as a .excalidraw file plus PNG preview. Includes a local Playwright renderer for visual QA and reference files for palette, JSON structure, and reusable element patterns.
Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `references/color-palette.md`, `references/element-templates.md` and `references/json-schema.md`).
It sits in Development, covering Diagrams. It works with Excalidraw and Playwright. The repository describes itself as: WorkBuddy skills / connectors / experts archive for offline study.
When your agent uses it
- A user wants a flowchart
- Architecture sketch
- Visual explanation
- Diagram as a .excalidraw file plus PNG preview
Example prompts
- “/excalidraw-diagram”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Bash
Workflow steps
10 steps, taken from the step headings in SKILL.md.
- 先判断深度
- 结构先行，不要先写样式
- 默认少容器、多层级文字
- 技术图必须给“证据”
- ：定义视觉论点
- ：列出区块
- ：选择视觉模式
- ：生成 .excalidraw
- ：本地渲染并回看
- ：修正后再交付
What it can do on your machine
Read from SKILL.md and the folder at commit 91b77ea. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uvbrew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, 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
Excalidraw Diagram loads about 951 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 221 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Bash
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); the scripts in this folder are not scanned.
