Purpose
This is the concept prototype — a fast, throwaway build that answers one question: "Is this core idea actually fun to interact with?"
Default use — run right after /brainstorm and /setup-engine, before writing
GDDs or architecture docs. Its verdict determines whether the concept is worth the
investment of full design documentation.
Mid-production? You can also run this at any stage to test a specific mechanic,
design change, or technical question. Pass --spike to activate spike mode: a
lightweight ~4-hour build with no GDD prerequisites and no phase gate implications.
Already have GDDs and architecture complete? To validate the full game loop
before committing to Production, run /vertical-slice instead.
