You'll have to check research publications if you want the latest stuff. The approach indicated in the comment you replied to is from this paper from February: https://arxiv.org/pdf/2402.03620

If you want the semi-latest stuff, you can also try various blogs, but they vary wildly in covered topics and quality.

emergentmind.com - trending AI papers, i just look at the simple papers that pop up from time to time and maybe check their reference links for something it builds on, occasionally get another LLM to extract the actual prompt style to test. I wish there was a simple pre-loaded prompt test arena actually, probably too expensive though. Every time there is an advance in proompting techniques it gets negated by model improoving so it's a funny space.

In your head. You just make some new weird shit up and try it to see if it works any better than the previous shit you made up.
