Microsoft open-sources SkillOpt for training Agent skill documents, reaching 3.3k stars in a week

一周3.3k star，微软开启Skills自我进化！像训练神经网络一样训练技能

Microsoft open-sourced SkillOpt, a text-space optimization framework that trains Agent skill documents without changing model weights; the paper reports best or tied-best results across 52 combinations covering 7 target models, 6 benchmarks, and 3 execution environments.

Why it matters: Microsoft’s open-source SkillOpt is a strong Agent tooling and research release. HKR-H has the 3.3k-star/trainable-skill hook, HKR-K has the text-parameter mechanism and 52 eval setups, and HKR-R hits agent engineering pain, so it lands in featured at 82.
