huh that's weird is it actually calling tools? or just saying it is.

Just saying it is its super weird, one time i got it to work was i told claude to prompt opencode and it did the action that way but any direct interaction i have or try with it, it just completely hallucinates and says its doing stuff and does nothing... Like i said its only a issues with gh opus 4.1
