What problem does it solve? Before committing a team to full Production, studios need proof that the complete game loop can be built at production quality on schedule. This Skill guides the end-to-end construction of a vertical slice and produces a PROCEED/PIVOT/KILL verdict that gates the Pre-Production to Production transition. ## Core Features & Use Cases - Scoped Slice Planning: Defines a falsifiable validation question, enforces a 3-5 minute polished gameplay scope, and applies a day-3 sunk cost checkpoint to stop runaway builds. - Structured Playtest Debrief: Runs a one-question-at-a-time debrief covering loop completion, time-to-first-action, core fantasy delivery, blockers, and pipeline feasibility. - Verdict and Reporting: Generates a vertical slice report with a day-by-day velocity log, routes PROCEED to epic and sprint planning, PIVOT to GDD revision with a carry-forward note, and KILL to a documented graveyard entry. - Use Case: After finishing GDDs, architecture, and UX specs for a roguelike, run the slice to prove one full start-challenge-resolution cycle is buildable in two weeks, then use the velocity log to plan the first production sprint. ## Quick Start Use the vertical-slice skill to validate my game's full loop at production quality and give me a PROCEED, PIVOT, or KILL verdict with a report.
