Guidance for Testcontainers — running Docker containers in automated integration tests. Covers Java (@Testcontainers, @Container, PostgreSQL/Redis/Kafka/Elasticsearch), Python (testcontainers-python with pytest), container lifecycle management (singleton, reuse), CI/CD integration (Docker-in-Docker, Ryuk), Testcontainer best practices, and database migration testing. Use when the user asks about testcontainers, integration testing with Docker, database testing, Java testcontainers, Python testcontainers, or needs to test with real Docker services. 使用场景：testcontainers、集成测试、docker 测试、数据库测试、Java Testcontainers、Python Testcontainers.

Guidance for debugging and troubleshooting Docker issues. Covers container startup failures (exit codes, docker logs, inspect), disk space exhaustion (system df/prune, log rotation), OOM and resource pressure (memory limits, stats), network connectivity problems (network inspect, iptables, DNS resolution), storage issues (permission denied, volume inspection), daemon problems (dockerd startup, socket permissions), and common error diagnosis. Use when the user asks about docker troubleshooting, docker debug, OOM, disk full, network issues, docker not starting, container crash, or needs to investigate Docker problems. 使用场景：docker 排查、docker debug、容器问题、OOM、磁盘满、网络不通、启动失败、配置问题.

Records decisions and documentation. Use when making architectural decisions, changing public APIs, shipping features, or recording context.

Create and manipulate Microsoft Word documents programmatically. Use when users need to generate, edit, or convert Word documents.

Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.

Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when correctness matters more than speed.

Create effective internal communications including emails, announcements, and team updates. Use when users need help drafting internal messages.

基于 Alibaba EasyExcel（com.alibaba:easyexcel:4.0.3）的 Excel 模板填充技能。覆盖简单对象填充、列表填充（{.}+forceNewRow）、横向多列组合填充（FillWrapper+WriteDirectionEnum.HORIZONTAL）、复杂填充（含合计行/统计行/先 fill 后 write）、Spring Boot 集成、模板设计规范、转义字符、03版/07版差异、性能优化（分次 fill、文件缓存）。当用户需要把 Java 对象或 Map 数据按预制 .xlsx 模板（变量语法 {var}、{.}、{prefix.}）填充生成报表（工资条/合同/对账单/发票/财务报表/统计表/汇总表）时使用此技能，不适用于不基于模板的"程序生成 Excel"场景（改用 easyexcel-write）。

基于 Alibaba EasyExcel（com.alibaba:easyexcel:4.0.3）的 Excel 数据读取技能。覆盖监听器模式（ReadListener/AnalysisEventListener/PageReadListener）、同步读取（doReadSync）、多 Sheet 读取、@ExcelProperty(index/name)匹配、多行表头（headRowNumber）、日期数字自定义转换器（@DateTimeFormat/@NumberFormat/Converter）、监听器异常处理（onException + ExcelDataConvertException）、额外信息读取（批注/超链接/合并单元格，extraRead + CellExtra）、公式和单元格类型（CellData<T>）、不创建对象的读（ReadListener<Map<Integer,String>>）、Web 上传读取（MultipartFile→InputStream）。当用户需要解析 Excel（导入数据/批量入库/对账文件/用户上传/Excel 转对象/Excel 转 Map）时使用此技能，不适用于按预制模板填充（改用 easyexcel-fill）、不适用于程序化生成 Excel（改用 easyexcel-write）。

基于 Alibaba EasyExcel（com.alibaba:easyexcel:4.0.3）的 Excel 数据写入技能。覆盖最简写入（3 种写法）、复杂表头（多级）、@ExcelProperty/@ExcelIgnore/@DateTimeFormat/@NumberFormat 注解、includeColumn/excludeColumn 选择列、@ColumnWidth/@ContentRowHeight 样式注解、@HeadStyle/@ContentStyle 自定义样式、合并单元格（@ContentLoopMerge/LoopMergeStrategy）、图片导出（File/InputStream/URL/byte[]）、超链接/批注/公式/富文本（WriteCellData）、动态表头、自动列宽、自定义拦截器（CellWriteHandler/SheetWriteHandler/RowWriteHandler）、分页分批写入、Web 下载直接写 OutputStream、03/07 版兼容。当用户需要程序化生成 Excel（无预制模板）导出订单/用户/财务/库存/报表/对账单/审批单等结构化数据时使用此技能，不适用于按预制模板填充（改用 easyexcel-fill）、不适用于读取 Excel（改用 easyexcel-read）。
