domain-driven-design SKILL.md skillA

domain-driven-design from ciembor/agent-rules-books is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add ciembor/agent-rules-books/domain-driven-design@git:20260909.802595f

Pins git:20260909.802595f in mdr.lock. Pin the fingerprint instead.

Apply Eric Evans-inspired DDD rules when modeling a complex domain, defining bounded contexts, protecting ubiquitous language, or designing aggregates.

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

Use this skill when a task involves strategic domain modeling, ubiquitous language, bounded contexts, context mapping, aggregates, repositories, domain services, or model-driven design.

Before making design or code decisions, read and apply [domain-driven-design.mini.md](domain-driven-design.mini.md). Use [domain-driven-design.md](domain-driven-design.md) only as a deeper reference when the mini rules are not enough for the current domain-modeling tradeoff.

How to install

The exact contents, by fingerprint

mdr add ciembor/agent-rules-books/domain-driven-design@sha256:2e50a4156197de93

The line at the top of this page pins the label git:20260909.802595f, 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.
