Some whitepapers I have found:

https://arxiv.org/html/2509.14483v1 https://arxiv.org/html/2402.07158v2 https://pmc.ncbi.nlm.nih.gov/articles/PMC13050940/ https://link.springer.com/article/10.1007/s10791-026-10331-6 https://link.springer.com/article/10.1007/s00766-026-00463-y

Is there a skill/prompt that has been accurately working for you?
