The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses npx to execute its search and retrieval functions. This is the primary mechanism for the agent to interact with the documentation repository and is consistent with the skill's intended purpose.
[EXTERNAL_DOWNLOADS]: The skill downloads and runs its core logic using npx from the modern-web-guidance package on the NPM registry. As the author is Google Chrome (a well-known and trusted entity), this is treated as safe behavior for a developer tool.
[REMOTE_CODE_EXECUTION]: The skill's documentation contains references and code examples for various browser polyfills (e.g., from unpkg.com, cdn.jsdelivr.net, and esm.sh). These are provided strictly for educational purposes and developer implementation guidance, posing no runtime risk to the AI agent's environment.
