title: "Cross-platform project sync: GitHub milestones to Linear projects to Notion"
difficulty: hard
category: composite
description: |
  Synchronize project tracking across three platforms. First, list all open
  GitHub milestones in "acme-corp/web-platform". For each milestone, find or
  create the corresponding Linear project (matching by name). Update the
  Linear project's target date to match the milestone's due date. Finally,
  create a Notion page under "Project Tracking" that shows a unified view
  of all projects with their GitHub milestone progress (open/closed issue
  counts) and Linear project status.
