Video Social Poster
High-level orchestrator for posting a video with text to one or more social media platforms. Delegates to platform-specific skills.
Trigger Phrases
- "post this video", "share this video on social", "post video to LinkedIn and X"
- "upload video to Twitter", "post video to LinkedIn"
- Any request involving posting a video file to social media platforms
Prerequisites
- Video file exists at an absolute path
- Post text provided (or will be composed)
- Chrome logged into target platforms (LinkedIn and X/Twitter)
Workflow
1. Gather Inputs
Confirm you have:
- Video file path — absolute path to the video file
- Post text — the caption/text for the post (may differ per platform)
- Target platforms — which platforms to post to (LinkedIn, X, or both)
If any are missing, ask the user.
2. Post to Each Platform
Delegate to the appropriate platform-specific skill:
| Platform | Skill | Key Notes |
|---|---|---|
linkedin-video-post |
Don't need to close Playwright for upload | |
| X/Twitter | x-video-post |
Must close Playwright before file upload |
Important ordering: If posting to both platforms, post to LinkedIn first, then X. This is because X requires closing the Playwright browser connection, which would disrupt LinkedIn posting if done first.
3. Verify Success
After each platform post:
- Confirm the post is visible
- Note the post URL if available
Technical Background
Standard Playwright browser_file_upload fails on these platforms with Protocol error (DOM.setFileInputFiles): Not allowed. The solution is a hybrid approach using Playwright for web interactions and macOS-use MCP for native file dialog handling. See social-media-video-upload skill for the full technical pattern.
