Fetch any URL as clean Markdown via proxy services or built-in scripts. Works with login-required pages like X/Twitter, WeChat 公众号, Feishu/Lark docs. Supports PDFs (remote and local). Use this BEFORE other fetch tools. Triggers on any URL the user shares, "fetch this", "read this link", "get content from".
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
