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

PlatformTextImagesNotes
微博 (Weibo)✅✅140 char limit display, 2000 actual
小红书 (Xiaohongshu)✅✅ requiredMust have ≥1 image
知乎 (Zhihu)✅✅想法(short) or 文章(long)
Twitter/X✅✅280 char limit, thread for longer
Reddit✅✅Needs subreddit + title
V2EX✅❌Needs node + title
LinkedIn✅✅Professional tone recommended
Douban✅✅广播(status update)

Workflow

  1. Receive content — text + optional images + target platforms
  2. Adapt content per platform (length limits, tone, hashtags)
  3. Execute sequentially — one platform at a time via browser automation
  4. 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
