The Agent Skills Directory

[SAFE]: The skill is entirely educational and focuses on frontend development best practices. It explains how adblocker filter lists work and provides guidance on renaming CSS classes and IDs to prevent legitimate UI elements (like cookie banners) from being hidden by extensions like uBlock Origin or EasyList rules.
[COMMAND_EXECUTION]: While the skill contains code snippets (JavaScript and CSS), these are provided as static documentation examples and are not executed by the agent or system. The provided isElementBlocked function is a standard utility for client-side visibility checks.
[EXTERNAL_DOWNLOADS]: The skill links to trusted documentation sources including MDN (Mozilla Developer Network), GitHub (uBlock Origin repository), and EasyList. These are recognized well-known services and do not involve remote code execution or suspicious downloads.
