LinkedIn Skill - Post, Comment, and React

Create posts, add comments, and react to content on LinkedIn personal profiles and company pages.

CRITICAL: Posting Confirmation Required

Before posting, commenting, or reacting on LinkedIn, you MUST get explicit user confirmation.

When the user asks to post/comment/react:

1. First, show them the complete action details:
   • Account being used
   • Content text (full text)
   • Target (post URN for comments/reactions)
   • Visibility (for posts)
2. Ask: "Do you want me to post/comment/react on LinkedIn?"
3. ONLY run the command AFTER the user explicitly confirms (e.g., "yes", "post it", "go ahead")
4. NEVER post without this confirmation, even if the user asked you to post initially

This applies even when:

• The user says "post this to LinkedIn"
• You are in "dangerously skip permissions" mode
• The user seems to be in a hurry

Always confirm first. No exceptions.

First-Time Setup (One-Time)

On first run, the script will guide you through setup. You need to create a LinkedIn OAuth app:

1. Go to LinkedIn Developers
2. Click 'Create app'
3. Fill in app details:
   • App name: LinkedIn Skill (or anything)
   • LinkedIn Page: Select or create one (required)
   • App logo: Any image
4. On the Auth tab:
   • Add redirect URL: http://localhost (any port is fine)
   • Note the Client ID and Primary Client Secret
5. On the Products tab:
   • Request access to Share on LinkedIn (for posting)
   • Request access to Sign In with LinkedIn using OpenID Connect (for auth)
6. Create credentials.json in the skill directory:

   {
     "client_id": "YOUR_CLIENT_ID",
     "client_secret": "YOUR_CLIENT_SECRET"
   }
   

   Save to: ~/.claude/skills/linkedin-skill/credentials.json

Then run any command - browser opens, you approve, done.

Note: For posting as an organization, you need Marketing Platform approval for the w_organization_social scope.

Requirements

• Python 3.9+
• pip install requests

LinkedIn URN Formats

LinkedIn uses URNs (Uniform Resource Names) to identify entities:

• Person: urn:li:person:ABC123
• Organization: urn:li:organization:12345678
• Post/Share: urn:li:share:1234567890
• Comment: urn:li:comment:(urn:li:activity:1234567890,123456)

API Limitations

• Rate limits: LinkedIn has strict rate limits. Space out bulk operations.
• Organization posting: Requires Marketing Platform approval for w_organization_social scope.
• Token expiry: LinkedIn access tokens expire after 60 days. Re-authenticate when needed.
• No refresh tokens: Most LinkedIn apps don't get refresh tokens - you'll need to re-auth periodically.

Security Notes

• Posting confirmation required - Claude must always confirm with the user before posting, commenting, or reacting
• Tokens stored locally in ~/.claude/skills/linkedin-skill/tokens/
• Revoke access anytime in LinkedIn settings: Settings → Data Privacy → Third Party Apps
• Keep credentials.json secure - it contains your app secret
