9# DDD Strategic Design
10 
11## Use this skill when
12 
13- Defining core, supporting, and generic subdomains.
14- Splitting a monolith or service landscape by domain boundaries.
15- Aligning teams and ownership with bounded contexts.
16- Building a shared ubiquitous language with domain experts.
17 
18## Do not use this skill when
19 
20- The domain model is stable and already well bounded.
21- You need tactical code patterns only.
22- The task is purely infrastructure or UI oriented.
23 
24## Instructions
25 
261. Extract domain capabilities and classify subdomains.
272. Define bounded contexts around consistency and ownership.
283. Establish a ubiquitous language glossary and anti-terms.
294. Capture context boundaries in ADRs before implementation.

31If detailed templates are needed, open `references/strategic-design-template.md`.
32 
33## Required artifacts
34 
35- Subdomain classification table
36- Bounded context catalog
37- Glossary with canonical terms
38- Boundary decisions with rationale

40## Examples
41 
42```text
43Use @ddd-strategic-design to map our commerce domain into bounded contexts,
44classify subdomains, and propose team ownership.
45```
46 
47## Limitations
48 
49- This skill does not produce executable code.
50- It cannot infer business truth without stakeholder input.
51- It should be followed by tactical design before implementation.
