Microsoft’s open-source SkillOpt automatically upgrades AI agent skills without touching model weights

Summary

Microsoft released SkillOpt, an open-source framework that optimizes AI agent skill files (.md). Traditionally, skill optimization requires manual instruction editing, which is slow and error-prone. SkillOpt treats skill documents as trainable objects, automatically exploring optimal instruction combinations via deep-learning-style optimization, boosting accuracy for models like GPT-5.5 without altering underlying weights.
