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)

1. Navigate to LinkedIn feed:

   browser_navigate → https://www.linkedin.com/feed/
   

2. Take a snapshot to find the composer
3. Click "Start a post" button to open the post composer modal

Phase 2: Write Post Text (Playwright)

4. Take a snapshot of the composer modal
5. Type the post text into the composer text area
6. Verify text appears correctly

Phase 3: Upload Video (macOS-use)

7. Get Chrome PID:

   pgrep -x "Google Chrome"
   

8. Do NOT close Playwright — LinkedIn works without closing it
9. 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
10. Wait for native file dialog (AXSheet) to appear
11. Press Cmd+Shift+G via press_key_and_traverse to open "Go to folder"
12. Type the absolute video file path via type_and_traverse
13. Press Return via press_key_and_traverse
14. Grep traversal for "Open" button (AXButton near bottom, y > 1500)
15. Click "Open" via click_and_traverse

Phase 4: Post (macOS-use)

16. Wait for video upload — LinkedIn shows upload progress. Wait for it to complete.
17. LinkedIn shows a video editing/trimming step — click "Next" to skip it
18. Click "Post" button
19. 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.
