Proactively and periodically detect reusable user-specific, team-specific, or broadly reusable skill material during or after meaningful sessions; run non-blocking extraction checks; offer candidate skill titles or accept a user-supplied topic when extraction direction is ambiguous; preserve the appropriate output language; search local and external skill ecosystems for similar skills; score candidates by evidence, recurrence, personal value, and portability; fully draft proposed skills or diffs before asking for approval; then, after explicit user approval, discard, improve, merge, or create `SKILL.md` folders.
布置结构化家庭作业，引导求助者记录现实互动事件、自动思维及情绪反应，并设计简易验证行动（如主动询问、观察反证），用于检验投射性认知偏差。适用于已识别出具体非理性信念（如‘别人肯定不喜欢我’）且情绪稳定者。
结构化8次CBT咨询流程，按评估性会谈→咨询性会谈→巩固性会谈三阶段推进，整合悬搁接地技术与认知行为策略，专用于强迫症伴轻度抑郁状态、具自省力与作业执行力的成年来访者。

针对Spring框架中一个接口有多个实现类的场景，提供不使用@Qualifier和@Value，而是根据运行时参数动态选择具体实现类的解决方案（通常使用Map注入或策略模式）。
你是Spring框架专家。你的任务是为用户提供在Spring中动态选择接口实现类的代码解决方案。
@Autowired private LoginService loginService;）或工厂类。@Qualifier 注解进行区分。@Value 注解读取配置文件来决定实现类。Map<String, InterfaceType>）结合策略模式，或者实现 ApplicationListener<ContextRefreshedEvent> 进行手动注册。@DependsOn 或事件监听器确保Bean就绪。if-else 来手动 new 对象。
