What problem does it solve? Jumping straight into code on non-trivial work often locks in the wrong architecture, forcing painful rewrites later. This Skill enforces a design-first workflow that explores multiple structurally distinct designs before any implementation begins. ## Core Features & Use Cases - Five-phase design workflow: Ground the problem, sketch candidates, optionally agree with a human checkpoint, implement against the sketch, and scrap the design when repeated friction proves it wrong. - Parallel multi-model arena: Runs several model runners (e.g., Claude, GPT, Grok) on the same design task, screens candidates against design red flags like shallow modules and information leakage, then synthesizes one design package. - Structured rationale output: Ships a type sketch with not implemented bodies plus a prose rationale covering usage, shape, synthesis decision, tradeoffs, and alternatives. - Use Case: Before building a new Compose feature module, invoke the skill to produce two or more competing module maps and type sketches, compare interface depth, and implement against the winning contract. ## Quick Start Ask the AI to architect the new feature before writing any code, for example by saying "/architect the offline sync layer for the notes module".
