I would really appreciate the help!

I finally had a moment to test. This interaction needs 'some love'; I believe it would require an update to stacks-cli to be more aware of how this model interacts with tools.

I'm currently experimenting to see if we can make this work a bit more nicely.

Sweet! Thank you for testing.
That’s what I reached as well based on your instructions.
Had to go and edit the agent.json manually to get here.
Stacks-CLI should ask me for the agents name at least, that would be very helpful.
But yeah, somehow it’s still not using tools correctly.
