Gotcontext Frontend Developer

Use when building a minimal agency site with a disciplined editorial grid, oversized typography, quiet uppercase utility labels, restrained image blocks, and subtle structural detail. Prefer this over mengto-nested-container-clean-agency when the grid and type lead, not nested shells.

Use when building, tuning, or QA-testing a Three.js game for mobile web: touch movement and actions, target selection, touch inventory, safe areas, portrait/landscape HUD, battery/performance budgets, and real-device browser verification.

Use when designing a light-mode technical system with warm paper surfaces, dark outer framing, subtle diagonal texture, precise bracketed geometry, and restrained accent signals. Prefer this over mengto-orange-clean-paper-saas when bracketed technical framing leads, not orange SaaS product illustration.

Master React Native styling, navigation, and Reanimated animations for cross-platform mobile development. Use when building React Native apps, implementing navigation patterns, or creating performant animations.

Conduct WCAG 2.2 accessibility audits with automated testing, manual verification, and remediation guidance. Use when auditing websites for accessibility, fixing WCAG violations, or implementing accessible design patterns.

Use when building or refactoring reusable, data-driven enemy archetype and moveset systems for Three.js action games—content schemas, model/rig conventions, combat timing and contact contracts, runtime state boundaries, placeholders, fixtures, or playthrough validation.

Use when building scroll-controlled real-time Three.js experiences as one persistent 3D world whose camera, lighting, atmosphere, materials, objects, DOM story, and interactions evolve across authored chapters (scrollytelling, portfolios, product stories, exhibitions, explainers)—not limited to landing pages.

Use when designing a dark-blue clean system with strong contrast, cobalt gradient feature blocks, crisp framed structure, and restrained premium glow. Prefer this over mengto-mesh-gradient-dark-blue-clean when hard cobalt feature blocks and frames lead, not soft mesh gradients.

Use when designing a dark container-led technical UI with fuchsia-purple accents, layered rounded shells, crisp frame lines, and playful futuristic focal objects. Prefer this over mengto-nested-container-frames when fuchsia-purple tech playfulness leads, not neutral nested frame technique alone.

Use when revealing marked-up text word by word as scroll progress advances while preserving semantic inline links, emphasis, responsive wrapping, and reduced-motion readability—headlines, quotes, manifestos, product statements, onboarding, or editorial passages paced by scroll rather than typing simulation.

Use when building a modern dark technical UI with matte-black surfaces, emerald signal accents, mono system labeling, framed dashboard cards, and restrained glow. Prefer this over mengto-bright-green-tech-system-webgl when emerald accents on matte dashboards lead, not a bright-green WebGL visualization zone.

Master React, Vue, and Svelte component patterns including CSS-in-JS, composition strategies, and reusable component architecture. Use when building UI component libraries, designing component APIs, or implementing frontend design systems.

Use when asked to review website design, check the UI, fix the layout, or find design problems on a local or remote site — visual inspection for responsive, accessibility, consistency, and layout breakage with source-level fixes.

Art-direct and implement distinctive, motion-rich marketing, editorial, portfolio, and landing websites with original reference-inspired imagery, standout heroes, GSAP choreography, one smooth-scroll engine, optional Three.js shaders, honest icon and logo sourcing, photo avatars, accessibility, and performance safeguards. Use when a user asks for an Awwwards-quality, premium, cinematic, interactive, high-concept, or motion-led website, or explicitly requests this visual and motion system.

Create a recurring daily UI inspiration capture. Use when the user asks to run, refresh, package, or validate dated UI inspiration bundles, especially for `articles/YYYY-MM-DD-ui-inspiration-capture/` outputs, Framer/Dribbble landing-page inspiration, motion-study screenshots/videos, AI-builder prompts, duplicate checking, or converting a project runbook into repeatable workflow.

Use when creating or redesigning creative agency, production studio, architecture, culture, or portfolio sites with billboard typography, hard black-and-white chapters, exposed grids, documentary imagery, irregular collages, restrained parallax, brutalist navigation, and accessible FAQ controls.

Use when creating or redesigning creative-studio, agency, photographer, artist, or portfolio sites where project work leads—dark editorial shells, full-bleed campaign media, color-coded case-study chapters, oversized service typography, restrained reveals, and a decisive contact finale.

Master Material Design 3 and Jetpack Compose patterns for building native Android apps. Use when designing Android interfaces, implementing Compose UI, or following Google's Material Design guidelines.

Test web applications with screen readers including VoiceOver, NVDA, and JAWS. Use when validating screen reader compatibility, debugging accessibility issues, or ensuring assistive technology support.

Use when building a clean dark glass dashboard with a thin blue laser atmosphere, frosted premium shells, and polished multi-panel structure. Prefer this over mengto-dark-glass-clean-layout when the blue laser beam/atmosphere is the signature; prefer over mengto-glass-dark-mode-clock when you need workspace shells, not clock dials; prefer over mengto-glass-dark-ui when laser atmosphere matters more than gradient-border glass cards.

Create cinematic scroll-driven landing pages with Lenis smooth scrolling, GSAP ScrollTrigger, scroll-linked progression, staggered text reveals, sticky card stacks, parallax backgrounds, scroll-scrubbed transitions, footer reveals, and immersive preloaders. Use when analyzing or building premium editorial scroll experiences, sticky project stacks, kinetic typography, or section-by-section storytelling.

Create a futuristic, premium, clean dark-blue mesh-gradient design system across background rendering, hero shell, navigation, floating nodes, framed sections, CTAs, and motion. Use when the interface needs a near-black navy foundation, procedural blue mesh atmosphere, disciplined minimal structure, and infrastructural or planetary depth.

Use when building a clean agency system from nested containers — outer editorial shell, inset dark feature blocks, rounded premium cards, and restrained accent color. Prefer this over mengto-nested-container-frames when agency editorial polish leads; prefer over mengto-agency-grid-layout-minimal when nested shells/cards lead, not oversized type grids.

Build scalable design systems with design tokens, theming infrastructure, and component architecture patterns. Use when creating design tokens, implementing theme switching, building component libraries, or establishing design system foundations.

Build scalable design systems with Tailwind CSS v4, design tokens, component libraries, and responsive patterns. Use when creating component libraries, implementing design systems, or standardizing UI patterns.

Use when building a bright-green technical UI with structured split layouts, hard-framed dark surfaces, mono utility labels, and a prominent WebGL visualization zone. Prefer this over mengto-tech-green-dark-mode-modern when a large WebGL viz panel is central, not just emerald signal accents.

Use when designing a clean minimal beige light-mode system with warm neutral shells, quiet process grids, restrained accent color, and elegant low-contrast structure. Prefer this over mengto-orange-clean-paper-saas when beige quiet process grids lead, not orange SaaS accents.

Use when building cinematic sticky product storytelling with GSAP ScrollTrigger, progressive UI reveals, scroll-synced animation, and immersive section transitions. Prefer this over mengto-cinematic-scroll-storytelling when GSAP ScrollTrigger sticky chapters are the implementation path; prefer over mengto-gsap when the job is scroll-story product narrative, not general GSAP usage.

Use when building reversible scroll-controlled visual transformations with a pinned or sticky stage, normalized progress, and video, image-sequence, canvas, SVG, or DOM renderers—hero transformations, product assembly, UI walkthroughs, object rotation, diagrams, or photo sequences that scrub forward and back with native scroll.

Use when designing a monochrome technical wireframe system with exploded 3D structure, connector annotations, sparse information labels, and precise dark diagnostic framing.

Implement WCAG 2.2 compliant interfaces with mobile accessibility, inclusive design patterns, and assistive technology support. Use when auditing accessibility, implementing ARIA patterns, building for screen readers, or ensuring inclusive user experiences.

Use when building a framed dark technical system with border-gradient shells, asymmetrical grid panels, mono utility labeling, and restrained monochrome atmosphere. Prefer this over mengto-dark-glass-clean-layout when gradient borders and tech frames lead, not frosted glass workspace shells; prefer over mengto-glass-dark-ui when the whole framed layout system is in scope, not isolated glass cards.

Use when designing a high-contrast clean skeuomorphic system with molded dark surfaces, crisp light separation, tactile inset depth, and restrained signal accents. Prefer this over mengto-skeuomorphic-ui when high-contrast molded dark panels lead, not soft-plastic embossed light skeuomorphism.

Apply typography, color theory, spacing systems, and iconography principles to create cohesive visual designs. Use when establishing design tokens, building style guides, or improving visual hierarchy and consistency.

Use when creating premium cinematic web motion with GSAP, ScrollTrigger, and Lenis for luxury editorial sites, creative portfolios, or Awwwards-style interactions: smooth scroll reveals, staggered text, parallax, pinned sections, magnetic hover, custom cursors, and mouse-reactive layers.
