一句话结论：微软 SkillOpt 证明优化后的 Agent 技能可跨模型和跨框架迁移，Codex 训练的 SpreadsheetBench 技能让 Claude Code 得分从 22.1 跃升至 81.8。原始信息强调，该研究最关键的发现并非 52/52 的满分成绩，而是技能工件在不同环境中的泛化能力，但迁移效果因任务类型差异显著，表格类任务保留率达 102%，数学类任务仅 10%。值得关注的原因是，这意味着 Agent 技能可以像软件包一样被训练一次、多处部署，极大降低重复训练成本，但任务类型对迁移效果的影响仍需深入研究。影响对象是研究 Agent 泛化能力的学者、构建多框架 Agent 系统的工程师，以及依赖 Claude Code 或 Codex 的自动化团队。下一步建议阅读论文第 4.3 节，并尝试将已训练的技能工件导入不同 Agent 框架，验证其在实际业务任务中的迁移表现。
