About Extension Publish

• [nitpick] The example uses empty values for --storage-account-name and --storage-container-name. Provide valid placeholders or remove those flags from the example.

text: az azure-data-transfer connection flow create --resource-group resourceGroup --connection-name connectionName --name flowName --flow-type "Mission" --location WestUs --status "Enabled" --storage-account-id /subscriptions/... --storage-account-name  --storage-container-name  --data-type "Blob"

[Copilot]

Currently load_arguments is a no-op, so CLI parameters won’t be registered. Implement argument loading or remove the stub to ensure commands accept their defined arguments.

Suggested change

	pass
	with self.argument_context('azure-data-transfer') as c:
	c.argument('source', options_list=['--source'], help='The source location for the data transfer.')
	c.argument('destination', options_list=['--destination'], help='The destination location for the data transfer.')
	c.argument('overwrite', options_list=['--overwrite'], action='store_true', help='Overwrite existing files at the destination.')

[Copilot]

The README usage section is a placeholder. Add actual usage examples or remove the placeholder text before publishing the extension.
