What problem does it solve? Validating a new game concept or mechanic normally requires production-quality code, which is slow and risky when the idea might fail. This Skill lets you test a concept quickly with relaxed standards, producing a clear PROCEED, PIVOT, or KILL recommendation backed by evidence. ## Core Features & Use Cases - Isolated Prototype Creation: Builds throwaway code in a dedicated prototypes/[concept-name]/ directory that never imports from or leaks into production source. - Structured Prototype Report: Generates a REPORT.md capturing the hypothesis, approach, measured results, metrics, and a PROCEED/PIVOT/KILL recommendation. - Timeboxed Scope Control: Enforces a 1-3 day effort limit and stops scope creep by reassessing whether the core question can be simplified. - Use Case: You want to know if a drag-and-drop floppy disk mechanic feels responsive in your Phaser game. Invoke the skill with the concept, and it builds a minimal test scene, measures interaction feel, and recommends whether to proceed with a full implementation. ## Quick Start Ask the assistant to prototype a drag-and-drop disk loading mechanic to test whether it feels responsive enough for the core gameplay loop.
