# Domain Modeling
The *active* discipline of shaping the model — challenging terms, inventing edge-case scenarios, and writing vocabulary down the moment it crystallizes. Merely *reading* a glossary for vocabulary is a one-line habit any skill does; this skill is for when you're changing the model, not consuming it.
## Artifact
Maintain the project's glossary in its existing convention. If there is none, create `CONTEXT.md` at the repo root. Record decisions that settle a term via `/create-adr` so the *why* is preserved separately from the *what*.
## Ubiquitous language
One term, one meaning, used everywhere — prose, code, docs, and the glossary agree. For each term write:
- A crisp definition.
- An **Avoid** list of the rejected synonyms, so the same concept never travels under two names.
When the same word means two things, that ambiguity *is* the work — split it into two named terms and retire the overloaded one.
## Sharpen by stress
Invent edge-case scenarios that a term must survive. A definition that can't classify the edge case is still fuzzy — refine it until it can, then write it down immediately. Flag ambiguities you can't yet resolve; record the resolution once decided.
Completion: every term touched has a definition and an Avoid list, and every flagged ambiguity is either resolved or explicitly parked.
