What problem does it solve? Product redesigns often blur operational meaning, hide technical evidence behind visual polish, or overwrite working baselines without governance. This Skill provides a governed contract for structuring product information architecture, state semantics, and acceptance evidence so design changes preserve product meaning and remain verifiable. ## Core Features & Use Cases - Information Architecture Definition: Establish workspaces, navigation, operational views, and technical/evidence depth proportionate to product scale. - Evidence-Backed State Semantics: Define explicit states such as HEALTHY, ATTENTION, DEGRADED, BLOCKED, and UNKNOWN tied to real product data sources, never treating UNKNOWN as healthy. - Governed Redesign Workflow: Protect known-working baselines, gate material redesigns behind candidate mockup review, and hand micro-polish and accessibility to dedicated specialists. - Use Case: When redesigning a monitoring dashboard, use this Skill to define the operational summary view, drill-down technical evidence, state definitions, identity asset slots, and a build handoff contract with an acceptance matrix before implementation begins. ## Quick Start Ask the AI to define the information architecture, state semantics, and acceptance evidence plan for a product redesign using the signalproof-design contract.
