小红书私信 · Android Computer Use

Read and reply to the user's 小红书 (Xiaohongshu) private messages by driving the app's UI on their own Android phone through Nexior's Computer Use accessibility service. This skill writes to the user's real account, so it is deliberately conservative: dry-run first, confirm before every send, and obey the red lines below.

适用范围（仅 Android / Nexior 手机端）— 先做运行时校验

This skill is Android-only. It requires the on-device computer.* screen-control tools (Nexior mobile + the "AceData Computer Use" accessibility service). Before doing anything else:

1. Call computer.screenshot. If it errors or the tools are unavailable → STOP and tell the user: this skill only runs on the Nexior 手机端 (Android) with Computer Use enabled — it does not work on desktop or web.
2. Confirm the screen is a phone running 小红书 (com.xingin.xhs). If 小红书 isn't installed/logged in → stop and ask the user to open and log into 小红书 first.
