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