小红书 Publisher

Create, format, and publish posts to 小红书 (Xiaohongshu/RED) through browser automation.

Requirements

• Python 3 with Pillow (pip install Pillow or apt install python3-pil)
• CJK fonts — fonts-noto-cjk on Linux (apt install fonts-noto-cjk), or Noto Sans CJK via Homebrew on macOS
• OpenClaw browser tool — access to a browser with the user logged into 小红书 creator portal
• A connected OpenClaw node (or sandbox browser) with Chrome/Chromium for browser automation

Overview

This skill handles the complete 小红书 publishing pipeline:

1. Draft — Write post content in 小红书 style
2. Cover — Generate a cover image (1080×1440)
3. Review — Send draft to user for approval via messaging channel
4. Publish — Use browser automation to post (or deliver for manual posting)

Workflow

Step 1: Draft Content

Create post content following 小红书 style. See references/content-guide.md for formatting rules, structure, and examples.

Key rules:

• Title ≤20 chars, with emoji hook
• Use --- section breaks, emoji bullets, short paragraphs
• End with question CTA + hashtags (8-12 tags)
• Save draft to memory/xiaohongshu-draft.md

Step 2: Generate Cover Image

Run the cover generation script:

python3 <skill-dir>/scripts/gen_cover.py --title "主标题" --subtitle "副标题" --tags "标签1,标签2,标签3" --output /path/to/cover.png

Options:

• --title — Main title (large text, required)
• --subtitle — Subtitle line (medium text, optional)
• --tags — Comma-separated feature tags shown as pills (optional)
• --badge — Top-right badge text (default: "OpenClaw")
• --output — Output path (default: cover.png)
• --gradient — Color scheme: purple (default), blue, green, orange, dark

Output: 1080×1440 PNG with gradient background, decorative elements, CJK text.

Step 3: Send for Review

Send the draft content + cover image to the user's messaging channel for review. Format:

📝 小红书草稿 — [主题]

标题：[标题]

[正文内容]

封面图已生成：[path]

请确认：
✅ 可以发布
✏️ 需要修改
❌ 不发

Never auto-publish. Always wait for explicit user approval.

Step 4: Publish via Browser

After user approval, publish using browser automation on the configured node.

See references/browser-publish.md for the complete browser automation steps.

Summary:

1. Navigate to https://creator.xiaohongshu.com/publish/publish
2. Enter title and body text
3. Upload cover image via browser upload action
4. Click publish

Fallback: Manual Publishing

If browser automation is unavailable (CDP issues, node offline, etc.), send the complete post to the user's channel with all content formatted for easy copy-paste:

📋 小红书发帖内容（请手动发布）

【标题】[标题]

【正文】
[正文内容]

【标签】[hashtags]

封面图：[path to cover image]

Known Limitations

• Mac Chrome CDP: Chrome launched via SSH/node may fail to bind --remote-debugging-port on macOS (GUI session required). If browser start fails, fall back to manual publishing.
• Login state: 小红书 creator portal requires login. If the session has expired, ask the user to re-login in their browser before proceeding.
• Pillow emoji: Pillow cannot render color emoji (NotoColorEmoji.ttf) — use text/icon alternatives in cover images.

Cron Integration

This skill works with cron jobs for scheduled daily posting. Typical cron setup:

Schedule: 0 8 * * * (Asia/Shanghai)
Session: isolated agentTurn
Delivery: announce to user's channel

The cron job message should reference this skill and include the content plan/topic for the day.
