 ## Go Port Sync Requirements
 
-**Current state:** The Go port has `generate-script` commands, the GitHub API client, shared commands, and cloud storage clients (Azure Blob, AWS S3, GitHub-owned multipart upload). Archive upload orchestration and GHES version checking are also ported.
+**Current state:** The `gei` CLI is fully ported to Go, including `migrate-repo`, `migrate-org`, and all alert migration commands. The GitHub API client, shared commands, and cloud storage clients are also ported.
 
 **When making C# changes, check if the Go port needs updating:**
