Identify business capabilities and classify subdomains (Core/Supporting/Generic), producing core-domain declarations, ownership recommendations, and bounded-context boundary candidates. Use when partitioning core/supporting/generic subdomains, or re-partitioning when god-context or circular-dependency signals suggest a subdomain misfire.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DDD Subdomains > English version: [English](SKILL.en.md) ## 使用时机 - 已完成领域发现（事件流与命令/事件候选已就绪），需要将领域切分为子域。 - 需要明确"什么是核心竞争力、什么可以外购/复用"的战略决策。 - `ddd-context-map` 报告"上帝上下文"或子域误分时，作为回溯目标重新执行。 ## 输入要求 - **必需**：事件流、命令/事件候选、边界线索（来自 `ddd-discover`）。 - **可选**：当前系统能力清单或模块清单、业务差异化假设、竞争优势描述（来自 `ddd-scope`）。 **输入缺失时的可观察出口**：若必需工件缺失或事件流为空，**不要**自行臆测分类。输出一段缺失声明：写明"缺少 <工件名>，来自 `ddd-discover`"，并列出为补齐需要跑的入口（无事件流 → 先跑 `ddd-discover`；价值主张不清 → 先跑 `ddd-scope`），然后停下等待。收到补齐材料后从头重跑流程。 **NOT for（不适用，转交对应技能）**： - 还没做领域发现、没有事件流 → `ddd-discover` 先行。 - 业务价值主张本身模糊 → `ddd-scope` 先行。 - 已确定子域、要做上下文划分 → `ddd-contexts`；本技能产出的是子域到上下文的**候选**，不定稿上下文。 - 本技能只做战略层切分，不做战术建模（聚合/实体/不变量 → `ddd-aggregates`）。 ## 流程 1. **提取能力集**：从事件流中抽取业务能力（Capability），去重合并同义能力。 2. **属性标注**：为每个能力标注业务价值、复杂度、变更频率、外部依赖程度。 3. **分类**：按 DDD 子域类型分类——Core（核心差异化）、Supporting（必要但非差异化）、Generic（通用可复用）。 4. **核心域声明**：形成核心域声明文档——为什么它是核心、衡量指标、长期演进方向。 5. **所有权建议**：建议团队归属，对齐语言边界与一致性边界；标注跨团队协作点。 6. **输出边界候选**：为 `ddd-contexts` 提供子域到上下文的初步映射建议。 ## 输出 | 工件 | 结构要求 | | :--------- | :------------------------------------------------------------------------- | …

How to install
mdr add ninjasln-labs/agent-skills/ddd-subdomains@sha256:3db4f674be7466ddThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
