Common Workflows

Publish to Single Platform

1. list_accounts → verify account exists
2. create_post(title, body_md) → get postId
3. publish_post(postId, [{platform}]) → get jobId
4. get_job_status(jobId) → track until done

Publish to Multiple Platforms

1. list_platforms → check capabilities
2. list_accounts → verify all target accounts
3. create_post(title, body_md) → get postId
4. publish_post(postId, [
    {platform: 'juejin'},
    {platform: 'csdn'},
    {platform: 'zhihu'}
  ]) → get jobId
5. get_job_status(jobId) → monitor progress

WeChat Article Formatting

render_wechat_html(markdown, {theme: 'default'}) → get html + css

Copy output to WeChat editor manually or via browser automation.
