DDD Strategic Design

Use this skill when

• Defining core, supporting, and generic subdomains.
• Splitting a monolith or service landscape by domain boundaries.
• Aligning teams and ownership with bounded contexts.
• Building a shared ubiquitous language with domain experts.

Do not use this skill when

• The domain model is stable and already well bounded.
• You need tactical code patterns only.
• The task is purely infrastructure or UI oriented.

Instructions

1. Extract domain capabilities and classify subdomains.
2. Define bounded contexts around consistency and ownership.
3. Establish a ubiquitous language glossary and anti-terms.
4. Capture context boundaries in ADRs before implementation.

If detailed templates are needed, open references/strategic-design-template.md.

Required artifacts

• Subdomain classification table
• Bounded context catalog
• Glossary with canonical terms
• Boundary decisions with rationale

Examples

Use @ddd-strategic-design to map our commerce domain into bounded contexts,
classify subdomains, and propose team ownership.

Limitations

• This skill does not produce executable code.
• It cannot infer business truth without stakeholder input.
• It should be followed by tactical design before implementation.
