What problem does it solve?
It solves the problem of uncertain, subjective visual review by comparing a generated UI screenshot against one or more reference images and producing deterministic pass/fail guidance.
Core Features & Use Cases
- Structured Visual QA Judgment: Produces a strictly formatted JSON verdict (score, verdict, differences, suggestions, and reasoning) for iterative editing loops.
- Category-Aware Matching: Flags whether the generated UI matches the expected visual category/style using
category_match.
- Actionable Remediation: Converts visual mismatches (layout, spacing, typography, color, hierarchy) into concrete next-step edits.
Use case example: Validate a generated dashboard screen against reference designs; if the score is below 90, drive the next edit cycle with targeted difference descriptions (e.g., spacing/typography shifts) until the UI passes.
Quick Start
Provide your generated UI screenshot and the reference images, then ask the skill to return a strict JSON verdict with differences and edit suggestions.
