+domain-modeling: trigger on discussing codebase terminology and on writing or editing a CONTEXT.md or an ADR directly, replacing the narrower "pin down domain terminology or a ubiquitous language" / "record an architectural decision" phrasing. Also drops the "another skill needs to maintain the domain model" caveat — that's the invoking skill's job to state explicitly, not this description's.
