principle-exhaust-the-design-space

What problem does it solve? When facing a novel UI interaction or architectural decision with no precedent in the codebase, committing to the first idea risks building the wrong thing. This Skill enforces a disciplined exploration step so you compare concrete alternatives before implementation. ## Core Features & Use Cases - Prototype Comparison Rule: Build 2-3 competing prototypes or sketches and compare them side by side before committing to one approach. - Applicability Guidance: Clearly defines when the principle applies (novel UI interactions, multi-approach architecture choices, feel-driven product decisions) and when it does not (mechanical implementation, bug fixes, single-approach constraints). - Use Case: You need to add a gesture-based navigation pattern that does not exist anywhere in your Android app. Instead of guessing, you build three small prototypes, compare how each feels, and only then commit to the best one. ## Quick Start Ask the AI to apply the exhaust-the-design-space principle to evaluate competing approaches for a novel UI interaction before writing the final implementation.
