Complete system for building high converting landing pages: intake questions, page structure, layout selection, conversion copywriting, SEO, plus strict visual rules for typography, spacing, corner radius, backgrounds, hero layout, icons, and motion. Use this skill whenever building, editing, styling, reviewing, or writing copy for ANY landing page, marketing site, web UI, page section, component, or prototype, even when the user does not mention design, conversion, tokens, or a design system. Always consult it before choosing page sections, headlines, CTAs, fonts, font sizes, spacing values, border radii, background colors, icons, or transitions.
Design, build, refactor, and audit user-facing interfaces. Use for UI/UX, accessibility, motion, design systems, AI interfaces, badges/status indicators, and rendered proof. NOT for backend APIs, tests, DevOps, routing, architecture diagrams, or non-UI docs.
Use this skill when analyzing existing video files using FFmpeg and AI vision, extracting frames for design system generation, detecting scene boundaries, analyzing animation timing, extracting color palettes, or understanding audio-visual sync. Triggers on video analysis, frame extraction, scene detection, ffprobe, motion analysis, and AI vision analysis of video content.
Interactive prompt studio for HappyHorse 1.0 video generation. Guides users through scenario discovery with vivid examples, then assembles production-ready prompts in JP/CN/EN. Use when someone wants to create AI video content with HappyHorse but doesn't know where to start, or when they have a specific scenario and need a polished prompt. Covers manga drama, character PV, manga motion, virtual idol MV, and free-form scenarios.
Use when the user is building or refactoring UI in their product codebase and wants designer-quality frontend code — not just functional code. Triggers on phrases like "design better", "make this UI feel more designed", "elevate the design quality", "build this with design best practices", "follow UX heuristics", "make this feel professional", "apply design polish", "review this for craft", or any request to apply UX/UI craft heuristics to code generation or review. Pairs with `docs/design.md` when it exists — the design system file owns **style** (colors, typography, spacing tokens, components), this skill owns **craft** (hierarchy, interaction, accessibility, motion, polish). Reference `docs/design.md` tokens by name for every visual decision; apply the 50-item heuristics catalogue and the Laws of UX catalogue below for every craft decision. When `docs/design.md` is absent, fall back to the codebase's existing design conventions and recommend the **Design System** skill. When a heuristic implies a token the design system doesn't have, flag it as a New Pattern to add via the **Design System** skill — never invent a value inline. Fully standalone.
This skill should be used when the user asks to "respect prefers-reduced-motion", "honor reduced motion", "make my animations accessible", "fix vestibular / motion-sickness issues", "add a useReducedMotion hook", "gate GSAP / Framer Motion / Lenis for reduced motion", or "meet WCAG 2.3.3 / C39". Provides tiered (not all-or-nothing) reduced-motion patterns in CSS and JS.
This skill should be used when the user asks to "build a color palette for a motion piece", "make a gradient background", "animate a color transition", "interpolate colors smoothly", "fix muddy/gray gradients", "convert colors to OKLCH", "color-grade a video for mood", "fix washed-out After Effects renders", "gamma shift", "Rec.709 vs sRGB", "colors shifted after rendering", or "match preview to final video". Covers palette construction, gradients, perceptual interpolation (OKLCH/Lab), grading order, and video/render color management.
This skill should be used when the user asks to "direct a motion graphics video", "do creative/art direction for a video", "define a motion language", "set the tone and pacing", "make the animation feel consistent", "decide what to animate (and what not to)", "turn a brief/brand into motion choices", or needs the senior creative judgment that sits above specific techniques (gsap/lottie/shader). Covers motion language, tone & energy, pacing/rhythm, motion hierarchy, restraint, and cross-shot consistency.
Improve or implement purposeful motion systems, micro-interactions, gestures, and transition behavior for production-grade UI. Use when the user mentions animation, motion, transitions, micro-interactions, hover states, drawers, toasts, gestures, or making the UI feel more alive.
Build falling leaves that read as leaves, with each one tumbling on its own axis so it presents a face, thins to an edge, and opens out again, and with its sideways slip driven by that same tumble. Covers the 2-D canvas build and the instanced-3-D variant, where leaves are recycled from, density-versus-count maths, depth layering, colour under a tone-mapped composite, reduced motion, and visibility pausing. Use for autumn maple, sakura petals, blossom, ash, snowfall shapes, or any drifting foliage where a generic particle field reads as confetti.
Diagnoses sales needs and sequences appropriate skills for comprehensive deal execution. Use this skill when unsure which sales skill to use, planning multi-step deal strategies, coaching reps on process, or coordinating complex sales motions.
This skill should be used when the user asks to "make this animation feel natural", "fix motion that feels stiff/floaty/cheap", "my animation looks robotic", "choose an easing curve", "how do I use the Graph Editor", "add overshoot or bounce", "Easy Ease isn't enough", "make snappy motion", "pick a duration for this transition", "stagger a list animation", "sync animation to a beat", or "review motion for good timing". It is the tech-agnostic foundation for deciding how something should move.
