LinkedIn Video Post
Posts a video with accompanying text to LinkedIn. Uses Playwright for web interactions and macOS-use for the native file upload dialog.
Prerequisites
- Chrome logged into LinkedIn
- Video file exists at an absolute path on disk
- Post text prepared
Step-by-Step Workflow
Phase 1: Open Composer (Playwright)
- Navigate to LinkedIn feed:
browser_navigate → https://www.linkedin.com/feed/
- Take a snapshot to find the composer
- Click "Start a post" button to open the post composer modal
Phase 2: Write Post Text (Playwright)
- Take a snapshot of the composer modal
- Type the post text into the composer text area
- Verify text appears correctly
Phase 3: Upload Video (macOS-use)
- Get Chrome PID:
pgrep -x "Google Chrome"
- Do NOT close Playwright — LinkedIn works without closing it
- Use
click_and_traverse on the "Add media" button (camera/image icon in composer toolbar)
- Find it in the Playwright snapshot first to identify its position
- Or grep the macOS-use traversal for "Add media" or the media icon
- Wait for native file dialog (AXSheet) to appear
- Press
Cmd+Shift+G via press_key_and_traverse to open "Go to folder"
- Type the absolute video file path via
type_and_traverse
- Press
Return via press_key_and_traverse
- Grep traversal for
"Open" button (AXButton near bottom, y > 1500)
- Click "Open" via
click_and_traverse
Phase 4: Post (macOS-use)
- Wait for video upload — LinkedIn shows upload progress. Wait for it to complete.
- LinkedIn shows a video editing/trimming step — click "Next" to skip it
- Click "Post" button
- Dismiss boost offer — LinkedIn may show a "Boost this post" dialog. Dismiss it by clicking "Got it" or the X button.
Troubleshooting
- "Add media" not found: Look for camera icon or image icon in the composer toolbar. Try snapshot/traversal to locate it.
- File dialog didn't open: Playwright may have intercepted it. Try closing Playwright (
browser_close), then clicking via macOS-use.
- Upload stuck: Large videos take time. Wait 30-60 seconds and check traversal for progress indicators.
- "Next" button not appearing: The video may still be processing. Wait and refresh traversal.
- Boost dialog blocking: After posting, LinkedIn often shows a boost promotion. Dismiss it before confirming success.
