How do you share custom patterns?

[ed4becky]

I have pull spec-kit into an app I already have 100's of hours into developing. I have certain custom patterns I have established for the project - how I want modals wrapped, certain things every screen on my SPA should have, notification patterns. How do I dictate that thru the spec-kit process - I notice the AI keeps trying to reinvent the wheel.

similarly, the AI keeps writing Angular zoned jest tests, even though I have dictated zoneless. same with not using standalone: true with Angular, since it is the default - the AI doesn't always listen. I have to remind it of the rules, then the AI fixes it, but sometimes not in the best fashion because it already had establishedf its own direction
