Microsoft's SkillOpt boosts GPT-5.5 by using nothing but a trained Markdown file Microsoft and three Chinese universities developed SkillOpt, a method that optimizes instruction documents for AI agents using principles from traditional model training. A simple Markdown file boosted GPT-5.5 by about 23 points on procedural tasks, and the same file transferred across models and agent environments like Codex and Claude Code.
