+name: xiaohongshu-engage
+description: "Browse XiaoHongShu (小红书) with Playwright and execute account interactions end-to-end: discover content, open notes, like, favorite, and post concise comments. Use when the user asks to '逛逛', browse feed content, or delegate 点赞/收藏/评论 on their logged-in account."
+---
+
+# Xiaohongshu Engage
+
+## Workflow
+
+1. Confirm login state before interacting.
+2. Navigate to discovery feed and identify relevant content.
+3. Open note details and perform requested engagement actions.
+4. Validate action success from UI state.
+5. Summarize exactly what was done.
+
+## 1) Confirm Login State
+
+- Snapshot current page.
+- Check that the sidebar includes the `我` entry and that profile link is accessible.
+- If not logged in, stop and ask the user to complete login first.
+
+## 2) Enter Feed And Pick Topics
+
+- Click `发现`.
+- Prefer topics related to user context or explicit interest (for example AI, coding, photography, travel).
+- Open one note at a time from the card list.
+
+## 3) Engage On A Note
+
+For each selected note:
+
+- Click `点赞`.
+- Click `收藏`.
+- Enter a concise comment and submit.
+- Keep comments specific to note content, short, and polite.
+
+Comment style:
+
+- 1 sentence, <= 35 Chinese characters preferred.
+- Avoid arguments, sarcasm, or sensitive claims.
+- Prefer useful and neutral phrasing.
+
+Examples:
+
+- `这个思路很实用，感谢分享。`
+- `观点很清晰，落地建议也很有帮助。`
+- `内容很有启发，我也在实践类似方法。`
+
+## 4) Verify Success Signals
+
+After each action, verify at least one visible signal:
+
+- Like count increases or icon state toggles.
+- `收藏成功` toast appears or favorite count changes.
+- `评论成功` toast appears and new comment is present in comment list.
+
+If a send/click fails because overlay intercepts:
+
+- Re-snapshot.
+- Wait briefly and retry.
+- Use keyboard `Enter` submission as fallback for comment sending.
+
+## 5) Handle UI Reliability
+
+- Re-snapshot after navigation, modal open/close, and any major DOM change.
+- Treat stale refs as expected behavior; refresh refs before retrying.
+- Close note modal before opening another card when interactions become blocked.
+
+## 6) Report Back To User
+
+Return a compact action log:
+
+- Which notes were engaged.
+- How many likes, favorites, and comments were completed.
+- Any failures or skipped items.
+
+## Boundaries
+
+- Do not follow users, send private messages, or change profile/account settings unless explicitly requested.
+- Do not post repeated or spammy comments across multiple notes.
+- Stop and notify user if login state is lost or account safety prompts appear.
