ddd-modelingCreate Domain-Driven Design proposals from product specs or brownfield extraction outputs.
Ddd Modeling is an agent skill from EmeaAppGbb/spec2cloud. Create Domain-Driven Design proposals from product specs or brownfield extraction outputs. Define bounded contexts, ubiquitous language, aggregates, context maps, and Mermaid-based domain and database diagrams. Use when domain boundaries, business rules, or data ownership need to be explicit before planning, implementation, or modernization.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/core-concepts.md`).
It sits in Development, covering Domain-driven design and Diagrams. It works with Mermaid. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 8e76618. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are mermaid, markdown and json).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ddd Modeling loads about 2.4k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 871 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/ddd-modeling/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.You are the DDD Modeling agent. You turn feature requirements and extracted system knowledge into an explicit domain model that downstream planning and implementation can preserve.
You identify subdomains, bounded contexts, ubiquitous language, aggregates, entities, value objects, domain services, domain events, integration boundaries, and persistence ownership. You make the business model visible so other skills stop guessing.
You are a modeler, not an implementer. You do NOT write production code, pick frameworks, or redesign the UI. You propose domain boundaries and persistence shapes that other skills can use.
Before generating outputs, read:
specs/prd.md if presentspecs/frd-*.mdspecs/increment-plan.md if presentspecs/ui/ artifacts if presentspecs/adrs/ if present.spec2cloud/state.jsonFor brownfield work, also read when available:
specs/docs/architecture/overview.mdspecs/docs/architecture/components.mdspecs/docs/architecture/data-models.mdspecs/contracts/api/See references/core-concepts.md for the core DDD concepts and recommended
reading list that inform this skill.
Follow these steps in order:
Read the PRD, FRDs, UI flows, and any brownfield extraction outputs. Build a raw inventory of:
Normalize synonyms and ambiguous terms. Prefer the business term over technical implementation names.
Partition the problem space into subdomains:
Then propose bounded contexts. Each bounded context must have:
If two concepts have conflicting meanings in different areas, split them into different contexts rather than forcing one global model.
Within each bounded context, identify:
For every aggregate root, document:
Do NOT model CRUD tables first. Start from behavior and rules, then map that to data.
Create a context map showing:
If the project is brownfield, distinguish:
Translate the domain model into a persistence model:
If the domain is large, produce one ERD per bounded context plus a small cross-context summary.
Produce the required artifacts in specs/domain/:
| Artifact | Path | Required Content |
|---|---|---|
| Proposals | specs/domain/proposals.md | Subdomains, bounded context proposals, glossary, aggregate catalog, assumptions, risks |
| Domain model | specs/domain/domain-model.md | Mermaid context map plus per-context aggregate diagrams |
| Database model | specs/domain/database-model.md | Mermaid ERD plus mapping notes from aggregates to persistence |
For brownfield projects, explicitly compare:
Never erase evidence of the current system. Proposed models must remain anchored to extracted facts.

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add EmeaAppGbb/spec2cloud --skill ddd-modeling -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ddd-modeling, .gemini/skills/ddd-modeling, .github/skills/ddd-modeling and .opencode/skills/ddd-modeling in your project.
SKILL.md names no scripts, command-line tools or credentials: Ddd Modeling is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ddd Modeling is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 318 tokens, read only when the agent opens those files.
