Thank you for reporting this issue! We have confirmed the problem and submitted a fix.

The issue you described, where JSON output was malformed when piped to other tools like jq, has been addressed. The fix ensures that all JSON data is now correctly sent to the expected output stream for proper piping support.

The fix is now under review: CortexLM/cortex-cli#13

Once the fix is merged, it will be available in the next release. Thanks for helping us improve!
