domain-modeling

构建与维护项目的领域模型与通用术语表。

把项目的领域概念、术语表和关键决策体系化，形成团队一致的 ubiquitous language，减少沟通歧义。在要确定业务词汇、记录架构决策或其他技能需要读写领域模型时使用。其特点是主动维护：遇到边界情况就质疑、澄清并立刻写下决策，保证模型随设计演进而更新。

# Domain Modeling

Actively build and sharpen the project's domain model as you design. This is the *active* discipline — challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallise. (Merely *reading* `CONTEXT.md` for vocabulary is not this skill — that's a one-line habit any skill can do. This skill is for when you're changing the model, not just consuming it.)

## File structure

Most repos have a single context:

```
/
├── CONTEXT.md
├── docs/
│   └── adr/
│       ├── 0001-event-sourced-orders.md
│       └── 0002-postgres-for-write-model.md
└── src/
```

If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts.
