Push a template change from your machine, open the editor, and it's already there. Opening a hosted workspace now pulls your latest commits, and Save pulls before it commits. If your changes and the editor's collide, you're shown the conflict to resolve.
What you need to do. Remove any calls to the old reconcile step: templates.reconcileWorkspace in the SDK and the templates_reconcile_workspace MCP tool no longer exist. Reopening the workspace does the same job.
See the CLI guide for the Git workflow.
