Based on the information provided in the extracts, there is a way to create relationships using the Ory CLI (Command Line Interface). The command

ory create relationships

is designed to create relationships from JSON files. This command can traverse a directory and create all relationships defined within JSON files found in that directory. You can also pass the special filename

-

to read from STD_IN, allowing for more dynamic input methods. Here's the relevant command syntax extracted from the documentation:

ory create relationships [flags]

And the options that can be used with this command include: - `--authority string`: Set the authority header for the remote gRPC server. - `--block`: Block until the connection is up. - `--format string`: Set the output format. One of table, json, yaml, json-pretty, jsonpath, and jsonpointer. (default "default") - `-h, --help`: help for relationships - `--project string`: The project to use, either project ID or a (partial) slug. - `-q, --quiet`: Be quiet with output printing. However, the documentation extracts provided do not explicitly mention the idempotency of creating relationships. Idempotency, in this context, would mean that running the command multiple times with the same input would not create duplicate relationships but would ensure that the desired state is achieved without side effects from repeated executions. For more detailed information on how to use this command and any idempotency features it might have, you would typically refer to the official Ory documentation or specific guides on using the CLI for managing relationships. Unfortunately, without direct information on idempotency in the provided extracts, I cannot confirm how the Ory CLI handles repeated executions of the

ory create relationships

command with the same input data. For further details, you might want to consult the Ory documentation directly, especially the CLI section: [ory create relationships](https://www.ory.sh/docs/cli/ory-create-relationships#ory-create-relationships).
