name	xhs-noteid
description	Extract Xiaohongshu (小红书) noteId from shared note text or URLs, including xhslink.com short links and xiaohongshu.com/discovery/item/<noteId> links. Use when the user asks for “noteId/笔记ID”, provides a 小红书 share message, or pastes an xhslink short URL that needs redirect expansion.

Extract noteId from XiaoHongShu shares

Fast path (no network)

• Find and return the <noteId> in URLs like https://www.xiaohongshu.com/discovery/item/<noteId>.
• Also accept share text that contains that URL; extract the same <noteId>.
• Prefer returning only the ID (or noteId: <id> if the user wants a labeled answer).

Short-link path (xhslink.com)

If the user only provides a short link like http://xhslink.com/o/..., expand redirects to a long URL, then extract the <noteId> from /discovery/item/<noteId>.

• Resolve redirect (requires network access/approval in sandboxed runs):
  • curl -sS -L -o /dev/null -w '%{url_effective}' '<short-url>'
• Extract <noteId> from the resolved URL.

Script

Use scripts/extract_noteid.py for deterministic extraction and optional short-link resolution.
