## FAQ

### Does the CLI support machine-readable output?

Yes, adding the --json flag to any command provides a machine-readable envelope containing the command status, data, and metadata.

### How can I prevent duplicate messages if a command fails?

You can pass a custom --idempotency-key to ensure that retrying the same operation with a stable key never sends the message twice.
