Domain Modeling

Actively build and sharpen the project's domain model while designing. Challenge terms, invent edge-case scenarios, and write the glossary and decisions down the moment they crystallise.

Reading the glossary for vocabulary is not this skill — that is a one-line habit any skill can do. This skill is for changing the model, not just consuming it.

Glossary file name. This skill writes CONTEXT.md (and CONTEXT-MAP.md for multiple contexts). A repo that already uses GLOSSARY.md / GLOSSARY-MAP.md keeps that name: read and update whichever the repo has, and never create the second one beside it. A repo with neither gets CONTEXT.md. Pick once, then the glossary below means the selected file and the map its -MAP companion.
