Autonomous UX copy improvement — rewrites unclear labels, error messages, microcopy, CTAs, tooltips, and onboarding text. Makes every word earn its place. Supports web and mobile.

Runtime sweep that catches mobile-layout bugs: content clipped off the edge of a phone screen, touch targets smaller than 44×44px, text inside a button or input that overflows its visible width, and modals that extend past the viewport. Loads the running web app in headless Chromium at 360px / 390px / 768px and repo...

Audit game user experience across HUD clarity, menu navigation, tutorial effectiveness, control responsiveness, camera systems, feedback loops, loading screens, and settings completeness. Detects game engine (Unity UGUI/UI Toolkit, Unreal UMG, Godot Control, web-based), maps all UI screens and input contexts, evalua...

Final autonomous quality pass before shipping. Fixes alignment, spacing, consistency, typography hierarchy, color harmony, motion timing, and every micro-detail that separates good from great.

Extract, consolidate, and modernize design tokens — oklch color scales, fluid spacing with clamp(), typography scales, motion timing, and shadow depths. Builds a systematic token architecture from scattered values. Use when: 'extract design tokens', 'create design system tokens', 'consolidate styles', 'modernize CSS...

Turn a design into production-quality frontend code: extract a design system with tokens and components, make layouts responsive across breakpoints, add dark mode with WCAG-compliant theming, then run a UX audit to validate everything. Use when implementing UI from Figma, adding theming, making an app responsive, or...

Set up internationalization by extracting all hardcoded user-facing strings to locale files.
