Does anyone know if it’s possible to have “ultrathink” be the default instead of saying it in every prompt?

Put it in CLAUDE.md because that just gets added to the prompt

		Ah, thank you! Now I feel like an idiot. I guess I was thinking “ultrathink” was a specially interpreted command within claude code (sort of like a slash command).
