Microsoft's optimizer that trains agent skills like neural networks, with epochs and validation gates, without touching weights.
SkillOpt treats a skill document as the trainable state of a frozen agent. It turns scored runs into edits, keeps only changes that pass validation, and outputs a deployable best_skill.md.
Follow the installation and training guide in the SkillOpt documentation linked from the README.
