The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill references several external libraries from unpkg.com, including three.js, d3.js, react, react-dom, and @babel/standalone. These are all well-known technology services. Several references (e.g., in built-in-skills/3d-object.md and starter-components/chart-stage.js) include subresource integrity (SRI) hashes, which is a security best practice to ensure the downloaded code has not been tampered with.
[DYNAMIC_EXECUTION]: The script agents/build-preview.mjs uses the new Function constructor to load the Babel library and to execute design component scripts within a proxy-based sandbox. This approach is used to isolate component code and provide a safe environment for previewing interactive designs. Similarly, agents/compile-design-system.mjs uses Babel to transpile JSX and TypeScript code. These behaviors are standard for design tools that require runtime compilation and rendering of user-authored components.
[COMMAND_EXECUTION]: The skill includes Node.js CLI tools (agents/gen-pptx and agents/gen-video) that use the playwright library to automate a headless Chromium browser for capturing slides and rendering animations. The video generation tool also spawns ffmpeg as a subprocess to encode PNG frames into video files. These operations are required for the skill's primary functionality of exporting design artifacts to professional formats.
