system-designlisted

## 执行环境 | 路径类型 | 说明 | |---------|------| | **使用方式** | 此技能提供模板和指导，**无需本地脚本执行** | | **调用场景** | 当用户需要系统设计、架构文档、技术选型时自动激活 | | **输出位置** | `docs/design-catalog/` 目录（相对于项目根目录） | ## 路径说明 - **无本地脚本依赖**：此技能生成文档模板，不涉及本地脚本执行 - **生成的目录**：保存在执行命令时的当前目录下的 `docs/design-catalog/` - **项目上下文**：基于当前工作目录确定项目根目录 # System Design Through EventStorming ## Overview Transform requirements into navigable design catalogs using EventStorming methodology and Mermaid diagrams. **Core principle:** Progressive elaboration through event-driven thinking, producing token-efficient visual artifacts in standardized catalog structure. **Announce at start:** "I'm using the system-design skill to create a design catalog for your system." ## When to Use **Use when:** - User wants to design a new system - Requirements exist but design doesn't - Need structured thinking before implementation - Team needs shared visual artifacts **Don't use when:** - Adding features to existing system (consider brainstorming instead) - Implementation already started - User wants code, not design ## Quick Reference | Phase | Key Activities | Output Files | |-------|---------------|-------------| | **1. Requirements** | Ask questions, identify actors/constraints | requirements.md | | **2. Big Picture** | EventStorming timeline with events/commands | big-picture.mmd | | **3. Processes** | Zoom into critical processes, add aggregates | process-{name}.mmd | | **4. Data & Flows** | ERD, state charts, sequences | erd.mmd, state-{en
