基础设施技能——维护项目 docs/ 目录的模块化组织和进度追踪。由编排器在 Plan 末尾和 Deliver 阶段强制调用，禁止跳过。模块文档按业务维度分目录存放详细内容，进度记录按日期/会话hash存放摘要。支持多人协作和跨会话任务追溯，文件头部标识 Git 账号。 务必在以下场景使用本 skill：创建文档、文档目录管理、docs 目录、产出物管理、输出文档、document output、docs management、模块文档、文档分类、多人协作文档、跨会话文档、进度记录、任务摘要、progress、会话记录、开发日志。
Infrastructure skill — maintains modular organization and progress tracking for the project docs/ directory. Mandatory invocation by orchestrator at end of Plan and during Deliver stages; must not be skipped. Module documents are organized by business dimension in subdirectories with detailed content; progress records are stored as summaries by date/session hash. Supports multi-person collaboration and cross-session task tracing with Git account identification in file headers. Use this skill when: creating documents, document directory management, docs directory, deliverable management, output documentation, document output, docs management, module documentation, document classification, multi-person collaborative documentation, cross-session documentation, progress records, task summaries, progress, session records, development logs.
Full-lifecycle flow orchestrator for project development. Upon receiving user input, it first classifies the input (4 tiers), then adaptively senses project context, scores task difficulty, selects the optimal route, and orchestrates the Plan→Execute→Validate→Deliver four-phase pipeline with quality gates and failure reflow. Use this skill when: the user wants to start a new project, receives a new requirement, needs a full development iteration, wants to go through the complete flow from requirements to delivery, or says things like "start building", "launch the project", "how to implement this requirement", "help me plan this", "do it end-to-end". When the user's intent is to complete an end-to-end development task (rather than just one step), use this skill to orchestrate the entire flow. If the user only needs a specific step (e.g., just write requirement docs), use the corresponding specialized skill directly.
Infrastructure skill — maintains project file tree snapshots and code structure summaries in a SQLite database (.cache/context.db) at the project root, solving the problem of models forgetting project structure across sessions. Mandatory invocation by orchestrator during context awareness stage (before route selection) and Deliver stage; must not be skipped. Scans all project files (source, config, docs, tests, assets), never modifies files. Use this skill when: understanding overall project structure, querying a module's file list and exported symbols, restoring project structure understanding across sessions, project awareness, context sync, project memory, code summary indexing, viewing project structure. This skill does not modify source code or manage document outputs.
项目开发全生命周期的流程编排器。接收用户输入后，先做输入分类（4 档），自适应感知项目上下文、评估任务难度、选择最优路径，编排 Plan→Execute→Validate→Deliver 四阶段并管理质量卡点和失败回流。 务必在以下场景使用本 skill：用户要开始一个新项目、接到一个新需求、要做一次完整的开发迭代、要从需求到交付走一遍完整流程，或者用户说"开始做"、"启动项目"、"这个需求怎么落地"、"帮我规划一下"、"从头到尾做一遍"。 当用户的意图是完成一个端到端的开发任务（而不是只做其中某一步），使用本 skill 来编排整个流程。如果用户只需要其中某一步（如只写需求文档），直接使用对应的专项 skill。
基础设施技能——在项目根目录 .cache/context.db（SQLite）中维护项目文件树快照与代码结构摘要，解决模型跨会话遗忘项目结构的问题。由编排器在上下文感知阶段和 Deliver 阶段强制调用，禁止跳过。扫描项目中所有文件（源码、配置、文档、测试、资源），不修改任何文件。 务必在以下场景使用本 skill：需要了解项目全局结构、查询某模块的文件列表和导出符号、跨会话恢复项目结构理解、项目感知、context sync、项目记忆、project memory、代码摘要索引、查看项目结构。本 skill 不修改源码，不管理文档产出。
API 接口契约与类型系统的详细设计工具。从领域模型和需求文档出发，生成 RESTful/GraphQL API 端点定义、Request/Response DTO 结构、错误响应标准、OpenAPI 规范以及类型代码骨架。产出输出到 specs/{module}/api-contract.md（按业务模块分目录）。 务必在以下场景使用本 skill：用户需要设计 API 接口、定义数据传输对象(DTO)、编写接口文档、制定错误码规范，或者用户说"设计接口"、"定义 API"、"写接口契约"、"DTO 设计"、"接口规范"、"错误码"、"OpenAPI"、"Swagger"。 当用户的任务涉及从业务模型到技术接口的转化时使用本 skill。
从设计文档生成项目代码骨架——包括目录结构、分层架构、Entity/Repository/Service 骨架、配置文件和测试框架初始化。执行阶段的核心工具，将 Plan 阶段产出的领域模型、时序设计、组件设计转化为可编译运行的项目框架。 务必在以下场景使用本 skill：用户要求初始化项目、生成代码骨架、搭建项目结构、创建 Entity、创建 Repository、创建 Service、项目脚手架、scaffold、项目初始化、从设计到代码、组件结构生成、代码生成、模块注册，或将 spec-writing 的交互流描述和 api-contract-design 的端点契约以及 engineering-principles 的架构模式转化为实际代码。
