helix add

Add a local instance or a Cloud database link

Reference

helix add local --name dev [--port 6969] [--disk | --storage-uri s3://bucket/prefix]
helix add cloud --name production [--database tenant:<id>|cluster:<id>] \
  [--project <id>] [--workspace <id>]

Cloud add uses the WorkOS session, verifies the selected database, and writes only stable IDs to helix.toml. If a project has multiple eligible databases, pass --database explicitly.
