What Domain Modeling does

Domain Modeling actively shapes a project's glossary and domain terms by challenging fuzzy language, testing edge cases, and updating CONTEXT.md as the model evolves. Use it when defining or refining concepts, and in read-only mode to apply the project's established vocabulary.

Domain Modeling is cataloged under AI Engineering on DirSkills. Domain Modeling comes from a repository tagged agent-harness, claude-code, claude-code-plugin, context-engineering and harness-engineering.

Documentation

README

Excerpt

Domain Modeling

Actively build and sharpen the project's domain model as you design. This is the active discipline — challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallise. (Merely reading CONTEXT.md for vocabulary is not this skill — that's a one-line habit any skill can do. This skill is for when you're changing the model, not just consuming it.)

Active vs read-only
