在 OpenClaw 中安装
/install excalidraw
功能描述
Generate hand-drawn style diagrams, flowcharts, and architecture diagrams as PNG images from Excalidraw JSON
安全使用建议
Install this only if you are comfortable with a skill that runs local Node.js code. Review setup.sh before first use because it installs npm packages and downloads fonts; keep generated input and output paths in temporary or workspace locations.
功能分析
Type: OpenClaw Skill
Name: excalidraw
Version: 1.0.0
The skill's functionality is to generate Excalidraw diagrams from JSON input and render them as PNG images. The `SKILL.md` provides clear instructions for the AI agent to generate JSON, save it to `/tmp`, and then execute a local `node` script (`scripts/render.js`) to produce a PNG, also in `/tmp`. The `scripts/setup.sh` installs necessary Node.js dependencies and downloads fonts (Virgil from `cdn.jsdelivr.net` and Cascadia Code from `github.com/microsoft`) required for rendering. The `scripts/render.js` processes local files and does not initiate any external network requests. All actions are directly aligned with the stated purpose, use standard temporary file locations, and download from legitimate sources, showing no evidence of malicious intent, data exfiltration, or prompt injection.
能力评估
Purpose & Capability
The stated purpose is diagram generation, and the artifacts consistently support that by creating Excalidraw JSON and rendering it to PNG.
Instruction Scope
Runtime instructions are limited to saving a diagram file under /tmp, running the specific local renderer, and returning the generated PNG.
Install Mechanism
The setup script runs npm install and downloads font assets from jsDelivr and GitHub; this is purpose-aligned but users should know it relies on external package and font sources.
Credentials
The renderer reads the specified input file, local font files, and writes the specified PNG output. That local file access and Node execution are proportionate for rendering diagrams.
Persistence & Privilege
No credential access, privilege escalation, background service, autonomous persistence, broad indexing, or hidden network behavior was found. Setup creates local dependency/font files only.
