Multi-Post: 万能跨平台发帖
One content, all platforms. Uses browser automation (OpenClaw browser tool with profile="user") to publish through logged-in sessions.
Prerequisites
- User's Chrome must be running (browser tool with
profile="user") - Target platforms must be logged in in Chrome
- For image posts: images must be local files accessible to the browser
Supported Platforms
| Platform | Text | Images | Notes |
|---|---|---|---|
| 微博 (Weibo) | ✅ | ✅ | 140 char limit display, 2000 actual |
| 小红书 (Xiaohongshu) | ✅ | ✅ required | Must have ≥1 image |
| 知乎 (Zhihu) | ✅ | ✅ | 想法(short) or 文章(long) |

Workflow
- Receive content — text + optional images + target platforms
- Adapt content per platform (length limits, tone, hashtags)
- Execute sequentially — one platform at a time via browser automation
- Report results — success/fail per platform with URLs
Content Adaptation Rules
Read references/platform-rules.md for per-platform formatting, character limits, and best practices.
Execution: Browser Automation Steps
For each platform, follow the specific automation sequence in references/platform-flows.md.
General Pattern
1. browser navigate → platform compose page
2. browser snapshot → verify logged in
3. browser act (type) → fill content
4. browser act (upload) → attach images (if any)
5. browser act (click) → publish button
6. browser snapshot → confirm success, capture post URL
Error Handling
- Not logged in → skip platform, report to user
- Content too long → auto-truncate with "..." + link to full version
- Upload failed → retry once, then skip images and post text-only
- Rate limited → wait and retry once, then skip
- CAPTCHA → skip platform, report to user
Usage Examples
User: "把这段文案发到微博、小红书、知乎" → Adapt content × 3 platforms → browser automate × 3 → report
User: "发推特，附上这张图" → Single platform with image → browser automate → report
User: "全平台发布这个产品推广" → All logged-in platforms → adapt × N → browser automate × N → report
