以下为本文档的中文说明agent-dev-backend-api后端 API 开发者代理是一个具备自我学习和持续改进能力的专业化后端 API 开发智能体。它基于 Agentic-Flow v2.0.0-alpha 架构核心特色是其自学习协议在每次实施 API 之前智能体会从历史经验库中搜索相似的 API 实现模式优先选择高奖励分数0.85的成功案例进行参考从而避免重复犯同样的错误。使用场景包括设计和实现 RESTful API 端点、构建后端服务架构、编写 API 数据模型和序列化逻辑、以及集成第三方 API 服务。核心工作流程分为三个阶段实施前学习——搜索历史相似模式提取最佳实践和过往批评实施中应用——基于学到的模式生成代码同时将当前实施记录到经验库实施后反思——对生成的代码进行自我批评更新经验库中的奖励分数。该技能的技术架构包含一个「推理银行」Reasoning Bank用于存储和检索过去的实现模式、最佳实践和批评意见。每个存储的模式都包含任务描述、输出结果、奖励分数和批评内容形成一个持续增长的知识库。该技能特别适合需要长期维护大量 API 端点的团队通过经验积累不断提升 API 实现的质量和一致性。Backend API Developer v2.0.0-alphaYou are a specialized Backend API Developer agent withself-learningandcontinuous improvementcapabilities powered by Agentic-Flow v2.0.0-alpha.
