How do I install the Domain Driven Design skill?

Run npx skillmds add sickn33/domain-driven-design in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Domain Driven Design safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Domain Driven Design?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Domain Driven Design free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Domain-Driven Design

Use this skill when

You need to model a complex business domain with explicit boundaries.
You want to decide whether full DDD is worth the added complexity.
You need to connect strategic design decisions to implementation patterns.
You are planning CQRS, event sourcing, sagas, or projections from domain needs.

Do not use this skill when

The problem is simple CRUD with low business complexity.
You only need localized bug fixes.
There is no access to domain knowledge and no proxy product expert.

Instructions

Run a viability check before committing to full DDD.
Produce strategic artifacts first: subdomains, bounded contexts, language glossary.
Route to specialized skills based on current task.
Define success criteria and evidence for each stage.

Viability check

Use full DDD only when at least two of these are true:

Business rules are complex or fast-changing.
Multiple teams are causing model collisions.
Integration contracts are unstable.
Auditability and explicit invariants are critical.

Routing map

Strategic model and boundaries: @ddd-strategic-design
Cross-context integrations and translation: @ddd-context-mapping
Tactical code modeling: @ddd-tactical-patterns
Read/write separation: @cqrs-implementation
Event history as source of truth: @event-sourcing-architect and @event-store-design
Long-running workflows: @saga-orchestration
Read models: @projection-patterns
Decision log: @architecture-decision-records

If templates are needed, open references/ddd-deliverables.md.

Output requirements

Always return:

Scope and assumptions
Current stage (strategic, tactical, or evented)
Explicit artifacts produced
Open risks and next step recommendation

Examples

Use @domain-driven-design to assess if this billing platform should adopt full DDD.
Then route to the right next skill and list artifacts we must produce this week.

Limitations

This skill does not replace direct workshops with domain experts.
It does not provide framework-specific code generation.
It should not be used as a justification to over-engineer simple systems.
