Read: Read Any URL or PDF

Prefix your first line with 🥷 inline, not as its own paragraph.

Fetch any URL or local PDF.

Outcome Contract

• Outcome: the user gets the useful content from a URL or PDF in the form they asked for.

• Done when: the answer is grounded in fetched content, paywall or extraction failures are explicit, and saved files are only created when requested or needed downstream.

• Evidence: original URL or file path, fetch tier, extracted text or metadata, and warning signals from the fetched content.

• Output: concise summary, clean Markdown, saved file path, quotes, citations, or extracted details, depending on the request.

• Plain "read this" / "看这个链接" requests: return a concise source-grounded summary, not a full Markdown dump.

• Quotes and citations: return the requested excerpt or relevant claim with its source, within applicable quotation limits.

• "convert", "fetch as Markdown", "全文", "save", and "下载": return or save the requested content as clean Markdown. For "原文", extraction, or /learn, match the requested passage or downstream scope; do not assume a full-text response.

• If the same user message asks for comparison, translation, extraction, or analysis, fetch first and then answer that request in the same turn.
