ddd SKILL.md skillA

ddd from svngoku/coding-agents-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add svngoku/coding-agents-skills/ddd@git:20261013.980e7e1

Pins git:20261013.980e7e1 in mdr.lock. Pin the fingerprint instead.

Domain-Driven Design system for software development. Use when designing new systems with DDD principles, refactoring existing codebases toward DDD, generating code scaffolding (entities, aggregates, repositories, domain events), facilitating Event Storming sessions, creating bounded context maps, or performing code reviews with a DDD lens. Covers both strategic design (bounded contexts, subdomains, context maps, ubiquitous language) and tactical design…

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

# Domain-Driven Design Skill

Apply DDD to build software that reflects deep understanding of the business domain.

## Quick Reference

| Task | Reference |
|------|-----------|
| Bounded contexts, subdomains, context maps | [strategic-design.md](references/strategic-design.md) |
| Entities, value objects, aggregates, repositories | [tactical-design.md](references/tactical-design.md) |
| Hexagonal, CQRS, Event Sourcing, Clean Architecture | [architecture-patterns.md](references/architecture-patterns.md) |
| Event Storming facilitation & documentation | [event-storming.md](references/event-storming.md) |
| Python implementations (Pydantic, SQLAlchemy, FastAPI) | [python-patterns.md](references/python-patterns.md) |
| TypeScript implementations (NestJS, TypeORM, Prisma) | [typescript-patterns.md](references/typescript-patterns.md) |
| DDD code review criteria | [code-review.md](references/code-review.md) |

## Core Workflow

### 1. Identify the Task Type

**Designing new system?** → Start with strategic design, then tactical
**Refactoring existing code?** → Assess current state, identify bounded contexts, refactor incrementally

How to install

The exact contents, by fingerprint
mdr add svngoku/coding-agents-skills/ddd@sha256:140d2efd7a5efe7a

The line at the top of this page pins the label git:20261013.980e7e1, 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.
