Domain Modeling

Degree of freedom: MIXED. Which term is canonical [HIGH freedom]; CONTEXT.md shape, lazy create, and the three ADR gates [LOW freedom — run exactly].

A shared language between user, agent, and codebase pays off every session: consistent naming, fewer tokens spent describing concepts, and a codebase the agent can navigate by vocabulary. Adapted from mattpocock/skills (MIT).

This is the active discipline — challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallize. Merely reading CONTEXT.md for vocabulary is a one-line habit any skill can do; this skill is for changing the model, not consuming it.
