Research direction
Investigate the promtool source code to understand how it currently handles the text format and where the format flag is processed. Look for any existing openmetrics library or format parser in the repository. The issue suggests adding a format flag, so examine the command line argument parsing in promtool. Check linked PRs or comments for any proposed implementation details.
