The tool I am developing focuses solely on analyzing LokerML metadata (based on https://cloud.google.com/products/agent-builder?hl=en) and provides users with guidance on actions to take or what is available. Governance is fully implemented on GCP with logging. The LLM will not handle the data directly; it will only process the commands.
