How to make spark communite with my other agents?

I have a Gemini Pro subscription. I mostly don't use Gemini spark and its quota remains unused. I use antigravity though.

I have Hermes setup on VPS. I have specialist profiles for tasks and crons running.

I want to utilise a Gemini spark agent as a researcher or something more that can take off some load from my Hermes agent.

As far as I know, Gemini spark does not have a CLI support. The only way I can make my Hermes agent give a task to spark is via an email and it is so annoying and time consuming.

Is there a good formal way to make the spark agent part of my agent team?

How do you guys "integrate" Gemini spark agent into your other agent harness/ecosystems?
