Domain Modeling Plus

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.

Runs alongside grill-me-plus sessions, wayfinder-plus grilling tickets, and to-spec-plus synthesis — anywhere terms get decided.
