The Agent Skills Directory

[COMMAND_EXECUTION]: The skill performs several local operations including npx storybook build, npm install, and the execution of Node.js scripts such as package-build.mjs and package-validate.mjs to bundle the user's design system.
[EXTERNAL_DOWNLOADS]: The instructions require the agent to install well-known development tools from the NPM registry, specifically esbuild, ts-morph, and playwright. It also triggers the installation of the Chromium browser for visual verification.
[REMOTE_CODE_EXECUTION]: The skill utilizes dynamic execution for its core bundling and validation logic.
package-build.mjs and lib/preview-rebuild.mjs support loading local logic overrides via import() from the .design-sync/overrides/ directory.
package-validate.mjs evaluates the syntax of the generated JavaScript bundle using new Function(). These patterns are consistent with the skill's purpose as a code transpiler and bundler.
[DATA_EXFILTRATION]: The skill reads repository source code and documentation to package them for upload to the claude.ai/design platform. Path validation logic in lib/common.mjs and package-build.mjs is used to prevent access to files outside the intended workspace root.
