LinkedIn Post

Post text + optional image to LinkedIn using CDP browser automation against a logged-in Chrome session.

Prerequisites

• Clawdbot installed (script auto-starts the browser if not running)
• Logged into LinkedIn (cookies at cookies/linkedin-zeusbycreatoros.json)
• ws npm package available

Quick Usage

Text-only post

node skills/linkedin-post/scripts/linkedin-post.js --text "Your post text here"

Text + image post

node skills/linkedin-post/scripts/linkedin-post.js \
  --text "Your post text here" \
  --image /path/to/image.png

Custom CDP port

node skills/linkedin-post/scripts/linkedin-post.js \
  --text "Post text" \
  --cdp-port 18800

Output

• stdout: Post URL (e.g. https://www.linkedin.com/feed/update/urn:li:share:...) or POST_SUCCESS_NO_URL
• stderr: Progress/error messages
• Exit 0: Success
• Exit 1: Error

How It Works

1. Connects to Chrome via CDP WebSocket
2. Finds or opens a LinkedIn tab, navigates to feed
3. Clicks "Start a post" to open the editor dialog
4. Injects text via innerHTML on LinkedIn's Quill editor (.ql-editor)
5. If image provided: clicks "Add media", uploads via DOM.setFileInputFiles
6. Clicks "Post" and waits for success dialog
7. Extracts and returns the post URL

Formatting Notes

• Double newlines (\n\n) become separate paragraphs
• HTML entities are auto-escaped
• LinkedIn supports emojis natively in post text
• @mentions in text appear as plain text (not linked mentions) unless LinkedIn auto-resolves them

Cron Automation

To schedule LinkedIn posts via cron, ensure the browser is running and LinkedIn session is active. Example cron job text:

Post to LinkedIn: "Your scheduled content here" with image /path/to/image.png

The agent reads this skill, runs the script, and confirms the post URL.

Troubleshooting

• Browser won't start: Script auto-starts via clawdbot browser start or the control server at :18791. If both fail, start manually.
• Not logged in: Re-import cookies or log in manually via browser automation
• Post button disabled: Text may be empty or image upload failed — check stderr
• Timeout on selector: LinkedIn UI may have changed — update selectors in script
