Excerpt

Define Language

Extract and formalize domain terminology from the current conversation into a consistent glossary, saved to specs/UBIQUITOUS_LANGUAGE_LATEST.md.

Distinct from model-domain and deepen-architecture: Use this skill to produce a canonical glossary of terms (words and definitions). Use model-domain to stress-test a plan through an interview that resolves domain model decisions. Use deepen-architecture to find module-level refactoring opportunities in the codebase.

HARD GATE — Ubiquitous language is NOT optional. Every term in the domain that could be misunderstood must be glossed. Ambiguity = rework.
