What this skill helps you build
Test one gameplay question with a timeboxed greybox loop, observable playtest criteria, and a keep-or-kill decision.
Patterns in the upstream playbook
The entrypoint covers: The prototype brief (fill this in before coding); Greybox the core loop, fake everything else (engine-agnostic pseudocode); Kill criteria — make the keep/kill call observable, not emotional; Containment: keep a spike out of the shipping codebase.
