教程：使用微软SkillOpt进行SearchQA提示优化，含基线对比与技能演化分析
英文摘要
This tutorial provides a complete coding implementation of Microsoft SkillOpt’s instrumented prompt optimization pipeline. It sets up the environment with OpenAI-compatible model access, using GPT-4o as the optimizer and GPT-4o-mini as the target model. A baseline evaluation is performed on the SearchQA validation set before running the optimization loop, which includes rollout, reflection, aggregation, selection, slow update, and meta-skill mechanisms. The training process is visualized with accuracy curves, edit-budget scheduling, and cumulative token usage. Finally, the evolved best skill is evaluated against the unseen split, demonstrating a measurable hard-match accuracy lift over the seed baseline.
中文摘要
本教程完整实现了微软SkillOpt的插桩提示优化流程。环境配置为兼容OpenAI的模型访问，优化器使用GPT-4o，目标模型使用GPT-4o-mini。在SearchQA验证集上先进行了基线评测，然后运行优化循环，包括rollout、reflection、aggregation、selection、slow update和meta-skill等步骤。训练过程通过准确率曲线、编辑预算调度和累计令牌用量进行可视化。最后，将优化后的最佳技能在未见过数据上评测，硬匹配准确率相比种子基线有可量化的提升。
