Antigravity as sql query generator

My main case for using an LLM is generating sql queries for reporting. I get the query and I run it on clients systems (copy and paste)

To improve the process I did:
- created custom gems with instructions and uploaded as knowledge base schemas and samples. It works but sometimes it mixes things up

- use Gemini API key with goose desktop and markdown files as knowledge base. It works much better but it costs me more than the 22€/month, depends on how complex the analysis is

SInce I still have Google Ai Pro, I was trying to use Antigravity to help me write the sql code, but the agent takes ages and does not produce any output.

Is it the right tool?
