ctaxnagomi Domain Modeling
Create and maintain a shared domain vocabulary and model that all code and tests reference.
Process
- Extract terms — What domain concepts appear in the conversation?
- Define precisely — Each term gets a clear, unambiguous definition.
- Map relationships — How do concepts relate to each other?
- Update CONTEXT.md — Write the glossary where the agent can reference it.
- Align code — Ensure code structure reflects the domain model.
Rules
- Every domain concept gets exactly one name.
- Definitions are precise and unambiguous.
- The glossary is the source of truth for vocabulary.
- Code should use domain terms, not technical jargon.
