What problem does it solve? Game map changes are easy to break visually and hard to review objectively. This Skill routes every map edit — moving zones, adding landmarks, drawing new terrain primitives, or designing whole new tier sheets — through a deterministic pin-guarded workflow with golden snapshot tests and blind-pass rubric verification, so visual regressions are caught and explained before shipping. ## Core Features & Use Cases - Job routing: Directs each map task (move/resize, add zone, new primitive, tier deltas, new tier sheet) to the correct authoring guide and procedure. - Golden pin discipline: Enforces vitest golden-snapshot checks after every edit, with a capture-review-regen loop for intentional visual changes. - Blind-pass verification: Runs a scoped blind-pass workflow on edited sheets, requiring all mandatory rubric lines to pass before committing. - Use Case: When asked to "add a zone to the T1 map" or "build the T2 valley sheet", the Skill enforces spec-first design, deterministic seeded rendering, and verified commits. ## Quick Start Ask the AI to add a new zone to the T1 map and verify it with the golden pin tests and blind-pass report.
