Auto-post GitHub code summaries to LinkedIn using Gemini AI

Description

How it works
Listens for a GitHub push event via Webhook
Lists and fetches all files from the pushed repository
Decodes base64 file content and merges it into a single text block
AI Agent (Gemini 2.5 Flash) analyzes the code and generates a article
A second AI Agent converts the article into a LinkedIn-ready post (max 2500 chars)
Automatically publishes the post to your LinkedIn profile

Set up steps
Connect your GitHub account and configure the Webhook in your repo's settings
Add your Google Gemini API key under credentials
Connect your LinkedIn OAuth2 account
Activate the workflow — posts will publish automatically on every push
