app_evaluator_skill

Overview

This skill evaluates mobile and web app interfaces with a strict, design-spec driven scoring system and delivers actionable improvement plans. It combines expert UI critique modeled on high-end product standards with quantitative scoring for performance against those standards. The output is a precise score plus prioritized recommendations for visual, interaction, and component-level fixes.

How this skill works

The evaluator inspects screenshots, design descriptions, and interaction flows to rate an app across style, hierarchy, layout, color, component detail, and typography. It maps observed traits to the acceptance rubric and produces a normalized score and short rationale. It then generates concrete, prioritized improvements tailored to the app’s category and desired aesthetic direction.

When to use it

• Before shipping a major UI release to verify acceptance-quality design
• When redesigning an app to move from generic to highly crafted visual language
• To audit competitor apps and identify stylistic gaps or opportunities
• During design reviews to prioritize fixes that improve perceived quality
• When training design teams on tactile, material-driven UI approaches

Best practices

• Provide high-resolution screenshots and a short interaction walkthrough for accurate evaluation
• Specify the target design archetype (e.g., handmade, glassmorphism, retro skeuomorphism)
• Share any brand color constraints or typography files to align suggestions with identity
• Prioritize recommendations by user impact and implementation cost
• Ask for follow-up validation after implementing top 3 recommendations

Example use cases

• Score a lifestyle app and convert a bland grid layout into a tactile scrapbook-style interface
• Audit a productivity tool and replace default controls with hardware-metaphor components to increase engagement
• Evaluate a game UI to enhance hero-object focus and tactile feedback for buttons
• Review a data visualization app and recommend glassmorphism or high-contrast palettes for clarity
• Prepare a festival-themed update by recommending feltmorphism, plush textures, and cultural color accents
