  • 3d-cloth-material

    Build convincing woven cloth in Three.js, with a thread-level weave normal map, sheen and anisotropic highlights, folds that never stretch the texture, hems with thickness, stitches, seams, frayed edges, fold occlusion, dye and wear variation, and light passing through thin fabric. Use for linen, silk, wool, canvas, curtains, banners, cloaks, tablecloths, tapestries or any 3D drape that currently looks like a plastic sheet, a stretched texture, or a flat coloured plane.

  • 3d-falling-leaves

    Build recognizable falling leaves in world space using instanced geometry, independent tumble, coupled sideways drift, shared wind, scene occlusion, and camera-aware recycling. Use for 3D autumn leaves or drifting foliage in Three.js and similar scenes; use falling-leaves for a 2D canvas overlay.

  • 3d-four-seasons

    Add coordinated spring, summer, fall, and winter states to a 3D scene, blending foliage, sunlight, sky, ground materials, snow, and particles without rebuilding the world. Use for seasonal controls, architectural walkthroughs, and outdoor scenes with four-season transitions.

  • 3d-high-poly-models

    Create or integrate highly detailed 3D models with smooth silhouettes, shaped surfaces, believable bevels, and close-up geometry, then prepare suitable runtime LODs and loading. Use when a user requests high polygon counts, ultra-realistic models, detailed architectural assets, or removal of visibly faceted geometry.

  • 3d-high-resolution-textures

    Build sharp, physically coherent high-resolution materials for 3D rendering with appropriate PBR maps, texel density, UV direction, mipmaps, anisotropic filtering, and progressive asset delivery. Use for detailed wood, stone, fabric, foliage, and architectural close-ups without excessive download or GPU memory costs.

  • 3d-metal-material

    Build hyperrealistic PBR metal in Three.js: steel, brass, gold, copper and iron as true conductors (metalness 1, measured F0 tint, no albedo) with roughness-varied finishes (polished, brushed anisotropic, aged with patina and worn edges) lit by a dark HDR studio of real bright window cards prefiltered with PMREM. Use when metal looks like grey plastic, a dull blur, or a black hole; when blades, tools, rings, ingots, hardware or product metal need reflections with edges and structure; or when a finish needs scratches, streaks, fingerprints and bevels that catch light.

  • 3d-orbit-inspect-demo

    Make a 3D object lean around on hover and open a full inspect view on click. Hover is a damped, bounded camera lean; click lifts the piece off its bench into the hand, where you drag to turn it, coast, dolly with wheel or pinch, and put it back with Esc, click-away or a Close button. Use for product, object, joinery and portfolio pieces in Three.js where a hover orbit and click-to-full-view must not fight each other; use webgl-3d-object for a floating hero mesh with no inspect mode, and 3d-virtual-tour for a camera path through a place.

  • 3d-paper-material

    Build a paper sheet in Three.js that reads as paper up close — washi, cotton rag or kraft with baked fibre and tooth relief, laid and chain lines, a torn deckle edge with frayed fibres, four-layer thickness, a rolled corner and crease, ink that wicks along the fibres, toasted aged edges, contact shadows and back-lit translucency. Use for a hung sheet, scroll, page, label, shoji pane or card that must survive a macro close-up, or when paper looks like a flat white plane, has ruler-straight edges, no thickness, or does not glow when lit from behind. Use 3d-wood-material, 3d-cloth-material or 3d-metal-material for those materials, and paper-cinder-transition for burning paper.

  • 3d-retina-resolution

    Render a 3D canvas sharply on Retina and HiDPI displays, including explicit 200 percent resolution, synchronized renderer and post-processing sizes, correct pointer coordinates, and measured quality fallbacks. Use for blurry WebGL output, 2x rendering, high-resolution previews, and display-density changes.

  • 3d-sky-background

    Create a camera-correct sky background for a 3D scene with a procedural atmosphere or panorama, horizon haze, aligned sunlight, and coherent environment lighting. Use for architectural skies, outdoor 3D backgrounds, golden hour, and day-to-night sky transitions.

  • 3d-sky-rays

    Add sun shafts and crepuscular rays to a Three.js or equivalent 3D scene, using scene occlusion, a projected sun position, controlled foreground spill, and scalable post-processing. Use for rays of light from the sky, sunlight through trees or roofs, and golden-hour architectural scenes.

  • 3d-ultra-realistic-water

    Build an ultra-realistic open ocean in Three.js with a deep-water Gerstner spectrum shaded per pixel from analytic derivatives, each wave faded at its own pixel footprint, plus Fresnel sky-cube and planar reflections, subsurface light through the crests, HDR sun glitter, Jacobian lace foam, a Kelvin wake, hull foam, buoyancy queries and aerial perspective into the sky's horizon haze. Use for seas, oceans, sunset or daylight water, sun glitter paths, ship or boat scenes, wakes, coastal flyovers and any 3D scene with a moving camera and a water horizon. Includes the approved water from Pirate Ship Sunset as a reusable module and demo.

  • 3d-underwater-god-rays

    Add volumetric underwater god rays to a Three.js scene, marching one drifting swell field along every view ray at half resolution so the light shafts converge on the sun, parallax with the camera and carry rippling caustic streaks, with a shimmering surface underside, a sun that wobbles through the ripples, and the same light dappling fish as they swim through the beams. Use for underwater scenes, oceans seen from below, aquariums, reefs, kelp forests, diving and shipwreck scenes, schools of fish, sunbeams or light shafts through water, caustics, "rays of light shining through the ocean", or watery ripples on a background. Includes a reusable module and the Blue Hour sardine-school demo.

  • 3d-virtual-tour

    Build guided and interactive virtual tours through a 3D environment with authored camera paths, room and floor-plan navigation, orbit inspection, smooth mode handoffs, and progressive loading. Use for architectural walkthroughs, real-estate tours, museums, showrooms, and explorable spaces built with Three.js or a similar renderer.

  • 3d-wood-lighting-scorecard

    Light carved wood in a dark room in three.js, with procedural grain and pores, one warm key through a window, soft shadows that touch, light shafts, background rays and dust, then score the render out of 10 on an anchored rubric with a runnable headless scorecard and iterate until each item reaches the target. Use for oiled timber, kumiko, joinery and workshop scenes; wood that reads flat, plastic or washed out; volumetrics that lift the blacks; "score this out of 10"; or "get the lighting to 8".

  • 3d-wood-material

    Build convincing timber for Three.js as one procedural MeshPhysicalMaterial with growth rings, cathedral figure, pores, medullary rays, checks, tool marks, end grain, and oil, wax, or lacquer finishes, so the grain follows the form and survives macro close-ups without image textures. Use for wood boards, benches, carved panels, tool handles, joinery, floors, and any request to make 3D wood look real, detailed, or less like a tiled photo or plastic.

  • add-mouse-driven-orbit

    Add restrained mouse-driven orbit and parallax depth to a Three.js hero by damping one pointer target and splitting it across camera translation, look-at, and small object rotations. Use for passive cinematic 3D heroes, pointer-responsive scenes, organic model parallax, and interactive depth where OrbitControls would feel like a product viewer.

  • add-shader-cursor-trail

    Add the Shaders WebGPU mouse effect used for the Tidal Commons hero: a white twinkling halftone cursor trail driven by ChromaFlow, masked through a DotGrid, finished with chromatic ripples and film grain, and protected by static, touch, accessibility, SSR, and performance fallbacks. Use when a user asks for this shader mouse effect, a halftone cursor trail, an interactive WebGPU hero/contact background, or a reusable cursor-following shader layer in React, Next.js, Vue, Svelte, Solid, or plain web projects.

  • agency-grid-layout-minimal

    Create a minimal agency design system with a disciplined editorial grid, oversized typography, quiet uppercase utility labels, restrained image blocks, and subtle structural detail.

  • ambient-section-particles

    Add a restrained particle atmosphere inside one section with configurable shapes, density, gravity, wind, sway, rotation, recycling or settling, pointer disturbance, visibility pausing, responsive limits, and reduced-motion fallbacks. Use for petals, leaves, snow, sparks, confetti, dots, paper, icons, or brand fragments that support a section's mood without obscuring content.

  • article-prompts-to-skills

    Convert an article, tutorial, or prompt pack into focused reusable AgentSkills, one independent capability per skill, with portable instructions, example prompts, working demos, preview screenshots, validation, gallery updates, and a narrow commit. Use when the user asks to turn an article's prompts, tutorial sections, design patterns, interactions, or workflow ideas into complete skills rather than leaving them as prose.

  • audit-ai-design-slop

    Audit websites, apps, screenshots, mockups, and design code for harmful AI-design clichés, generic generated defaults, and established UI defects. Use when the user wants evidence-backed design feedback, an anti-slop review, or a removal-first cleanup plan without a speculative redesign.

  • audit-reference-originality

    Audit a website or digital experience against its supplied source references for originality and plagiarism risk. Use when Codex must compare current or historical site output with reference pages, capture packs, screenshots, copy, brands, numbers, images, assets, videos, layouts, motion, or code; raise evidence-backed red flags; distinguish common visual grammar from distinctive copying; and propose concrete fixes without making unsupported legal claims.

  • audit-verify-explain-grade-5

    Audit work, verify claims with concrete evidence, and explain the result in simple grade-5 language. Use when the user asks to review, audit, check, verify, explain a change, explain a fix, summarize test results, validate whether something works, or translate technical findings into plain language for non-technical readers.

  • aura-asset-images

    Use when you need high-quality stock-style images from Aura Assets (aura.build/assets) similar to Unsplash for design mockups and marketing: backgrounds, abstract wallpapers, architecture, portraits, and headshots. Includes a workflow for searching by tag on aura.build/assets and returns 5 real image URLs per category plus practical guidance for using different resolutions and aspect ratios.

  • browser-video-recording

    Create polished 60 fps 4:3 4K browser screen-recording style videos from Codex in-app browser captures, with browser-only crop, natural macOS cursor styling, deliberate click choreography, zoom-follow framing, ffprobe/thumbnail verification, and optional native recording compatibility checks. Use when the user asks to record or re-record browser actions, show cursor clicks and zooms, make Dribbble/UI inspiration or product demo recordings, or asks whether Codex, Playwright, or an MCP can produce a natural browser demo video.

  • build-awwwards-quality-sites

    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.

  • build-daily-inspiration-sites

    Turn a completed daily UI inspiration capture into exactly five original landing-page builds, one per separate Codex task, using Sites. Use when the user asks to turn the daily inspiration references, a five-item UI prompt pack, or a dated `*-ui-inspiration-capture` article into distinct HTML landing pages while changing the source brands, names, copy, people, numbers, pricing, claims, and imagery.

  • build-wireframe-scan-reveal

    Reveal Three.js geometry with an expanding world-space scan whose wire cage leads the solid surface, then burns away. Use for wireframe scanning, radial mesh reveals, survey pulses, holographic assembly, topology intros, and 3D model entrances where a plain opacity wipe does not explain the form.

  • cinematic-gsap-lenis-motion-system

    Create premium cinematic web motion systems with GSAP, ScrollTrigger, and Lenis. Use for luxury editorial websites, creative studio portfolios, Awwwards-style interactions, smooth scroll reveals, staggered text, parallax, pinned sections, magnetic hover states, custom cursors, and mouse-reactive layered movement.

  • corner-diagonals

    Apply diagonal-cut corners and chamfered edges to buttons, cards, panels, and container shells. Use when a design needs precise geometric framing, sci-fi UI surfaces, clipped-corner controls, or engineered sharp containers instead of rounded pills or plain rectangles.

  • corner-lasers

    Create a corner-anchored laser composition with thin beams, a bright emitter node, bloom, and atmospheric glow or fog.

  • create-game-vfx

    Create readable, performance-safe Three.js game visual effects. Use for attacks, impacts, damage feedback, status effects, spell trails, particles, shaders, telegraphs, quality tiers, and reduced-motion alternatives.

  • dither-background

    Create a dark monochrome procedural background with enlarged square pixels and visible Bayer-style ordered dithering. Use when a page needs an atmospheric near-black dither field, broad organic waves or cloud masses, and restrained gray-white highlights behind framed UI, hero content, or data overlays.

  • dither-laser-dark-mode

    Create a dark premium design system that combines near-black surfaces, subtle ordered-dither texture, and a thin accent-colored laser atmosphere.

  • documentary-brutalist-agency

  • editorial-service-booking

    Create or redesign appointment-based service websites for salons, barbers, spas, wellness studios, clinics, and hospitality brands. Use for warm editorial layouts, serif-led identity, documentary portrait crops, calm treatment selectors, location-aware booking, and operational states that remain elegant and trustworthy.

  • editorial-tech

    Blend editorial magazine composition with precision product-tech detailing using asymmetrical grids, cinematic media bands, mono utility labels, and restrained accent color.

  • elevenlabs-tts

    Generate ElevenLabs text-to-speech audio from scripts or inline text using local voice profiles. Use when the user asks for ElevenLabs, text-to-speech, TTS, narration, voiceover, speech audio, or voice generation; load voice names, voice ids, emails, owners, and account-specific defaults only from local config outside the skill.

  • falling-leaves

    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.

  • fire-paper-loader

    Build a burning-paper ring loader whose GLSL flame is drawn by a Worker on an OffscreenCanvas started from the head, so a main thread blocked by the page build cannot freeze it, with a progress count, an even-paced run into the hand-off, and a clean fade to the page. Covers the ember thread and ember gradient, porous char, worker start-up, parallel shader compile with a waited 1-px warm-up draw, hand-off without a stall, reduced motion and hidden-tab behaviour. Use for a loading screen, preloader, page loader, splash, "kindling", burn loader, ember ring, burning paper hole, fire loader, or a loader that must keep moving while heavy JavaScript, three.js or shader builds hold the main thread.

  • fire-smoke-skill-vfx

    Build the effects of a fire skill as one visual language in Three.js. Flames that read as fire, not as orange fog or cones: ray-marched flame volumes whose turbulence rises with buoyancy (slow at the root, accelerating and stretching as it climbs) instead of scrolling, a temperature ramp from a white-hot core a little above the fuel through yellow and orange to deep red tips, broad brighter licks inside, walls of fire broken into clumps of separate tongues of very different heights with notches between them and licks that detach and go out, a fire whirl wound in helical sheets with a waist and a blue root; charcoal smoke drawn premultiplied over the frame and lit only by the fire (cauliflower billows for a burst, a thin streaked curtain off a grass-fire front, fibrous wisps off small fires, ragged hot cracks inside a burst's smoke); embers and sparks that drift on a curl field, cool from white through orange to red and fall as ash; heat haze as refraction; firelight shared with the world; a world-space heat map that makes the ground's needles smoulder as hairlines and its pockets breathe; and gentle ink impact frames limited to three flashes a second. Use for fire or flame skills, fireballs, fire waves or breath, rings of fire, fire tornadoes or whirls, burning ground, wildfire fronts, smoke columns, embers, smouldering aftermath, "fire and smoke", "realistic fire", "flame thrower", "inferno", "burning field" or "skill effects only". Includes a reusable module and a five-beat demo on a scanned CC0 burned-ground floor with failure-mode switches.

  • framed-grid-layout

    Create minimal framed grid layouts with thin visible boundary lines, L-shaped corner brackets, subtle diagonal line texture, and strict section alignment. Use when asked for clean, neutral, precise, structured, editorial, technical, or guide-border web layouts.

  • funky-purple-container-tech

    Create a dark container-led technical design system with fuchsia-purple accents, layered rounded shells, crisp frame lines, and playful futuristic focal objects.

  • game-dev-combat-animation

    Build, fix and review character combat animations (melee strikes, bow shots, spell casts, skills, monster attacks, whole move sets) so they read like Diablo IV, Baldur's Gate 3 or Elden Ring and never stretch, lock, wring or break an arm, wrist or hand. A written standard with numbered rules, per-frame tests on the real skinned mesh, keys designed from upper-arm, forearm and blade intents, checks from every camera the player sees, two blind critics plus a blind A/B against the last release, and every critic claim verified against full-resolution frames and live-rig numbers. Use when creating or reworking any attack, skill or move set; when the user says arms, hands, wrists, elbows or weapons look stretched, weird, broken or wrong; when they ask for a standard, rules or tests for animations; or when they ask to score animations or get them to N out of 10.

  • game-dev-combat-skill-polish

    Score a game's combat skills and spells out of 10 with blind judges, then raise the weakest to a bar, for timing and readability (does a skill read as itself, does the blow land when it lands) and for art (detail, light, trails, impact, art direction, judged against a reference such as Diablo IV). Covers filming casts on a stopped, stepped clock, contact strips and close-ups, anonymised two-judge rounds, the levers that moved scores (hero props made from a painted concept with image-to-3D, own schedules and keyed moves, painted additive textures, camera-facing ribbons, light outside the body), the traps that cost points, asset and load budgets, and shipping each skill as its own version. Use when the user asks to score, review, improve, polish or rebuild combat skills, spells or attacks; says a skill "doesn't make sense", "looks bad" or should look like another game; names a target score; or starts a "next skill" thread. Project specifics (review hooks, harness settings, where each skill's code lives, scores so far) go in an optional local references/<project>.md next to this skill.

  • generate-reference-inspired-brand-worlds

    Generate multiple original brand campaign worlds from a supplied visual reference while controlling how close the new work feels without copying protected signature elements. Use when a user provides a brand identity image, poster, editorial campaign, moodboard, or generated concept and asks for inspired alternatives, several distinct brands in one visual family, a closer-to-reference V2, exact wordmarks inside images, or originality-safe image-generation prompts and outputs.

  • glass-dark-mode-clock

    Create a dark glass design system with frosted shells, soft beam grids, circular clock-like calibration dials, and precise sci-fi instrument framing.

  • glass-dark-ui

    Build dark-mode glassmorphism interfaces with readable contrast, frosted surfaces, and gradient borders using a pseudo-element mask. Use when asked for glass cards, frosted dark hero sections, blur panels, or dark UI systems with gradient/glow borders.

  • globe-gl

    Use when implementing globe.gl (Globe.GL) for 3D globe data visualization with WebGL/ThreeJS, including setup, data layers (points, arcs, polygons, labels), and integration patterns in plain HTML or React.

  • globe-particles

    Create a globe-like 3D particle visualization with a dense luminous spherical core and thinner orbital ring or flattened disc. Use when a design needs a premium planetary, orbital, synthesized data-globe effect rendered with real WebGL/Three.js particles, not generic starfields or full page layout changes.

  • gooey-blob-system

    Create a gooey blob system using SVG filters where multiple shapes merge into a single fluid form. Use overlapping circles combined with a Gaussian blur and color matrix filter to produce a continuous, organic mass. The forms should visually fuse and separate based on proximity. Focus on filter-driven merging (blur + threshold effect), soft organic boundaries with no hard edges, multiple independent shapes behaving as one system, and smooth continuous motion that feels fluid and cohesive.

  • gsap

    Use when implementing motion with GSAP and you want practical animation structure and sequencing guidance.

  • horizontal-scroll-scenes

    Build scene-by-scene chapters that advance left to right on one fixed stage while the user scrolls vertically, with native scroll as the only input. One pure function turns scrollY into scene, dwell and move, so forward, reverse, scrollbar drags, fast skips and reload at depth all land on the right frame. Covers dwell versus transition budgets, a burn-wipe or pan between scenes, chapter index and progress UI, glide-to-scene links that skip intermediate scenes, keyboard and reduced-motion behaviour. Use for horizontal scrollytelling, multi-scene product tours, "scroll down to travel sideways", chapter carousels driven by the wheel, or any piece where a wheel-jacked slider keeps breaking on touch, keys, refresh or back.

  • html-demo

    Show an app working on a web page by drawing it live in HTML instead of recording it. A Mac-style window plays the app step by step, and every frame is a pure function of one clock, View(t), drawn on a fixed 1200 × 750 stage that one CSS scale fits to any width. The pointer is scripted, labels and pictures come from the real app, a steps bar sits under the window, it plays only while on screen, and reduced motion gets designed end frames. Use when someone wants a product demo, an animated app window or hero, a feature walkthrough, "the UI animated and simulated in HTML", "like a screen recording but HTML", an interactive product tour on a landing or download page, or wants to replace screen recordings, GIFs or MP4s of their UI with crisp live HTML. Also use to build many such windows at once with helper agents, or to scrub, freeze and screenshot them.

  • html-reel

    Turn a tweet, a video, a YouTube video or a landing page into a 9:16 reel (Instagram Reels, TikTok, Shorts) that says what the source says and looks like it, with every cut on a word. Read the source (its words, its media, its measured fonts and colours), pick a structure (a promo, a showcase, "found this", an explainer, before and after), write the script in the creator's voice from the source's own facts, make the voice with timestamps (their cloned ElevenLabs voice), then build the picture from HTML scenes drawn from one clock (window.__frame(t)) in the source's look, opening on its cover (the hook's best moment as the first frame), its demo video framed and cut to words, and assemble it in Fil's video editor over MCP. The creator is in it from the first draft as a placeholder in the camera layouts (a backlit studio silhouette) (full frame, a bubble, half the frame), swapped for their phone takes when they record, and everything retimed to their own words by word anchors, t = W(τ); a reel can also be faceless. Use when someone wants a reel, a short or a vertical video from a post, a thread, a launch, a landing page, a demo video or a YouTube video, "a reel like this one", or a talking-head promo cut to their own delivery.

  • html-to-interaction-prompts

    Convert a supplied HTML page or generated HTML reference into a screenshot-backed article containing multiple reusable interaction prompts. Use when the user provides an HTML file, exported page, generated-page.html, or local/live reference and asks to extract animation/interactions, create prompts, capture screenshots for each prompt, add them to an article, or commit the resulting article/assets.

  • ice-frost-skill-vfx

    Build the effects of an ice and frost skill as one visual language in Three.js. Frost that grows like real frost, not a painted fern: a dendritic tree grown on the CPU from a seed point, stems racing outward with barbs and sub-barbs that compete for space in one time-ordered queue, side branches leaned toward their tips, baked into a distance field so the shader draws hairline feathers growing out from the seed with a bright tip, rime, crystal glints and a contact shadow. Faceted ice spikes built from half-spaces and ray-traced against their own planes (Snell, Fresnel, total internal reflection, Beer-Lambert blue, trapped bubbles, a fracture network, frosted edges) that erupt along the frost line, crack along visible planes and shatter into convex pieces that tumble, land on a face and rest, with snow lumps and ice chips settled into the crust. A low freezing mist marched as wind-stretched banks that churn in place and part around the ice, a blizzard column of powder on helical strands with a fibrous veil, glinting diamond dust, and a scanned snow floor with dunes, broken crust, a raking moon with self-shadow and two populations of glints. Use for ice or frost skills, frost novas, ice spikes or walls, glacial eruptions, shattering ice, blizzards, snow devils, freezing mist, frozen ground, "ice and frost", "frost creep", "ice shards", "realistic ice" or "skill effects only". Includes two reusable modules and a five-beat demo on a scanned CC0 snow floor with a failure-mode switch.

  • lightning-energy-skill-vfx

    Build the effects of a close-combat energy skill as one visual language in Three.js. Lightning that reads as lightning, dynamic but never in your face: trees of strips (trunk, forks of forks, hair-fine branchlets) with a fine white core in a violet-blue glow, each channel reaching out as a stepped leader, flaring as it connects, holding its shape and fading through an afterglow, one discharge at a time; a storm-cloud orb (a lit billow surface that churns in place, 10-15 plasma-globe arcs from a small white core to its inner wall, crawlers on the rim, a hairline fresnel); ground strikes that flash when the leader arrives, crawl along the stone's own cracks and reflect in wet stone (the demo's floor is a scanned CC0 texture); a torn black shadow with dry-brush edges that hangs off the orb and streams behind it, air bursts felt as refraction, orange sparks, fractured rocks that land or float in a storm domain, and impact frames that hold, invert in two-tone ink with tapered speed lines, shake and bend the lens, limited to three flashes a second. Use for anime or dark-fantasy skill effects, lightning or thunder fists, plasma or energy balls, charge-ups, dashes with shadow trails, ground strikes, storm or domain rings, ultimates, hit-stop, impact frames, negative flashes, screen shake, "black lightning", "thunderstorm fist", "realistic lightning", "afterimage" or "skill effects only".

  • mesh-gradient-dark-blue-clean

    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.

  • nested-container-clean-agency

    Create a clean agency design system built from nested containers, with an outer editorial shell, inset dark feature blocks, rounded premium cards, and restrained accent color.

  • nested-container-frames

    Create a container-in-container layout system using nested frames. Use an outer centered container with visible vertical boundary lines and corner markers. Inside, place inner containers inset from the edges, each with its own background and rounded frame. Technique: outer container defines global bounds, inner containers use padding to create inset spacing, layered frames (border + background) to separate levels, and consistent spacing between outer frame and inner blocks.

  • no-ai-design-slop

    Prevent and remove generic AI-generated design defaults, incoherent visual choices, and established UI defects while creating, revising, or reviewing websites, apps, screenshots, mockups, and design code.

    Profile, audit, and optimize frontend page performance with emphasis on animation work, memory-leak risks, long-session slowdowns, CSS animations, canvas/WebGL requestAnimationFrame loops, marquees, skeletons, GSAP/Three/Matter effects, timers, listeners, and observers. Use when the user asks to make animations performant, pause offscreen animations, look for memory leaks, profile pages that slow the computer over time, fix janky scrolling, reduce CPU/GPU use, or repeat the "only play in view" optimization on React/Vite/Next/frontend pages using Codex Browser.

  • orange-clean-paper-saas

    Create a clean paper-toned SaaS design system with warm neutrals, orange accent signals, rounded premium forms, and polished product illustration surfaces.

  • paper-cinder-transition

    Change between pages, chapters or scenes with a paper-burn transition, a ragged ember line that sweeps across the frame, chars the old page ahead of it and reveals the next scene live behind it, written as one WebGL composite pass over a frozen frame and a scissored live scene. Covers the front's silhouette, the luminous ember gradient with a beading gold thread, torn porous charcoal that is alpha-masked, baked noise, finite-difference slopes, the 0.75-scale live scene, sweep direction, timing, reduced motion and visibility pausing. Use for a burn transition, paper burn, cinder wipe, chapter change by fire, charring page reveal, burn-away section change, ember dissolve, or when a fade, slide or generic dissolve between scenes reads as cheap.

  • performance-profiling

    Guide performance profiling for Apple platform apps with Instruments, Xcode diagnostics, and MetricKit. Use when investigating app hangs, stutters, high CPU, memory leaks, memory growth, OOM crashes, slow launch, battery drain, thermal issues, App Store performance readiness, or when adding os_signpost and measurement hooks.

  • pointer-trail-emitter

    Build a cursor trail whose spacing stays constant at any hand speed, by emitting motes per unit of distance travelled rather than on a timer, so a flick draws the same continuous ribbon as a crawl instead of breaking into scattered dots. Covers sub-segment placement, the ring-buffer ordering trap, the idle breath a distance emitter needs, anchoring the trail to the screen in a 3-D scene, scaling scatter against the plane it hangs on, coasting instead of stopping dead, touch and reduced-motion fallbacks, and why moving the emitter to a DOM overlay to raise its z-index costs more than it buys. Use for cursor wisps, pointer sparks, embers, magic trails, comet tails, plankton, dust, or any mote trail that must stay legible however fast the hand moves.

  • product-proof-saas

    Create or redesign SaaS and AI product landing pages where a real workflow, interface, or deterministic demo is the central proof. Use for pale atmospheric shells, product UI in the hero, prompt-to-output stories, audience tabs, compact feature modules, honest pricing comparisons, and FAQ handoffs.

  • publish-project-to-github

    Package a finished local project into an intentional GitHub repository, create a strong README and visual preview, push it safely, configure a public GitHub Pages URL when the project is compatible, and verify the deployed result. Use when a user asks to upload, publish, open-source, share, or turn a local HTML/CSS/JavaScript experiment or small web project into a documented GitHub repository with a live demo.

  • reveal-hover-effect

    Build cursor-following spotlight reveals that expose a second aligned image through a soft radial mask.

    Turn any ordered process into a data-driven vertical or horizontal scroll story with a base line, progress fill, active step states, responsive collapse, semantic fallback, and reduced-motion behavior. Use for onboarding, checkout, roadmaps, recipes, case studies, service processes, histories, or narratives where progress through the sequence should become visible while scrolling.

  • scroll-scrubbed-visual-sequence

    Build reversible scroll-controlled visual transformations with a pinned or sticky stage, normalized progress, and video, image-sequence, canvas, SVG, or DOM renderers. Use for hero transformations, product assembly, interface state walkthroughs, object rotation, diagrams, or photo sequences that must move forward and backward with native scrolling.

  • scroll-scrubbed-word-reveal

    Reveal marked-up text word by word as scroll progress advances, while preserving semantic inline links, emphasis, responsive line wrapping, and reduced-motion readability. Use for headlines, quotes, manifestos, product statements, onboarding messages, or editorial passages where scrolling should pace comprehension rather than simulate typing.

  • scroll-world-storytelling

    Turn an article, case study, brand narrative, product journey, or long-form story into a cinematic scroll-driven landing page using one of three renderers: scrubbed video, a real-time Three.js world, or semantic HTML/SVG data and typography. Use when the user asks for a scroll world, fly-through landing page, article-to-website transformation, animated planet, data scrollytelling, video-scrubbed page, connected visual journey, or story-led alternative to ordinary stacked sections.

  • shaders-cursor-ripples

    Add cursor-following fluid WebGPU distortion over an existing image with the Shaders library's ImageTexture and CursorRipples components. Use when a hero, gallery, or media panel needs a water-ripple mouse effect; when replacing a drifting CSS spotlight or flashlight reveal; or when a prompt says to borrow only the shader interaction from a Shaders.com reference while preserving the current brand, image, copy, and layout.

  • ship-web-games

    Package, deploy, and verify a playable Three.js or web game. Use for release builds, asset delivery, private/public deployment, production smoke tests, browser proof, release notes, rollback readiness, and cleanup of temporary QA resources.

  • stitched-full-page-capture

    Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

  • tailwindcss

    Use when you are implementing UI with Tailwind and want reusable, practical utility-first patterns.

  • threejs

    Use when building 3D scenes, interactions, or WebGL-backed interface moments in Three.js.

  • threejs-landscape

    Build a live Three.js landscape that stays quiet behind a subject — a noise heightfield on a polar grid so resolution follows the lens, ground coloured by slope and moisture rather than by texture, instanced GPU grass whose wind costs nothing on the CPU, scattered stones, a gradient sky dome, a star field you can actually see, and a time-of-day system that cross-fades instead of cutting. Use for hero backdrops, product stages, scroll worlds, or any scene where a building, object, or figure has to sit in a place rather than float on a gradient.

  • threejs-towers

    Generate architecture procedurally in Three.js and film it assembling — a small geometry vocabulary that builds pagodas, castles, domes and spires from parameters instead of mesh files, hip roofs with flying eaves driven by a single profile function, and a clipping-plane build animation where everything below a rising line is finished work and scaffolding stands above it. Use for construction studies, architectural title sequences, procedural landmarks, or any hero object that should build itself rather than fade in.

  • threejs-weather

    Put weather into a Three.js scene that reads as weather — rain anchored inside the frustum, a storm that is the rain leaned on rather than a second system, lightning on its own light with thunder scheduled by distance, snow that blows up into blizzards and keeps settling until the ground goes white, wet ground with puddles and splashes, and looping ambience that has no seam. Use for scene atmosphere, seasonal states, hero backdrops, or any world where clear/rain/storm/snow needs to be a control the viewer can turn.

  • tune-enemy-ai

    Build, debug, balance, or test combat enemy AI for playable action games. Use for aggro, target selection, navigation, spacing, attack choices, telegraphs, retreats, boss behavior, behavior-state machines, and deterministic AI regression tests.

  • unsplash-asset-images

    Use when you need to pick high-quality Unsplash images for product/design assets (avatars, headshots, portraits, large website backgrounds, and abstract wallpapers) and output real Unsplash URLs plus practical instructions for producing the right resolutions and aspect ratios (1:1, 4:5, 3:4, 16:9, 9:16).

  • vantajs

    Use when adding animated WebGL background effects with Vanta.js (setup, parameters, resizing, performance, integration in React/Next.js).

  • video-to-superprompt

    Turn a reference video into a super detailed recreation or inspiration prompt. Use when the user provides, mentions, uploads, links, or points to a video and asks to analyze the design, UI, animations, transitions, scroll interactions, typography, colors, assets, WebGL/Three.js, storytelling, section-by-section behavior, or to create a prompt/article that recreates the page, app, interaction, or motion system.

  • water-crystal-skill-vfx

    Build the effects of a water and crystal skill as one visual language in Three.js. Water that reads as clear water, never a teal fill or a textured ball. A ray-marched water orb whose surface swells, rings and deforms in place: it refracts the frame behind it with an inverted horizon, has a silver rim and sharp highlights, and shows a faint caustic web on its far wall. Streams wound up from tide pools as uneven beaded ropes with silver edges, drips and shed drops. A lash that unspools from the orb, whips and pours into a pool under a torn, lopsided splash crown of aerated white water with spikes breaking into drops. Analytic ripple rings and rain on the pools. Crystals traced against their own half-space planes (Snell, Fresnel, total internal reflection, exit dispersion, Beer–Lambert, fracture discs, a white-hot root glow and a resonance band that climbs the stone), growing out of the water in a draining veil, then shattering into Voronoi shards that fall, tumble and rest with real contact on a heightfield. Caustics on the pool floor, and a moonlit tidal rock flat: rock banks traced from target images onto a world grid, flat mirror pools, a moon-glitter column of micro-facet glints, and a moon disc with maria. Use for water or ice-crystal skills, water orbs or bubbles, water whips, jets or tentacles, splash impacts, tide pools, rain, crystal growth or eruption, crystal resonance, shattering glass or quartz, caustics, wet-stone night scenes, moon reflections on water, "water and crystal", "hydro", "clear water VFX", "crystal shatter" or "skill effects only". Includes a reusable module and a five-beat demo on a scanned CC0 low-tide floor with failure-mode switches.

  • web-technique-to-skill

    Turn a visual or interaction technique you already built into a reusable web-design skill, by isolating the one mechanism that makes it work while reproducing its approved reference exactly around that focus, and packaging it with a demo that proves both the mechanism and the visual fidelity. Covers finding the mechanism, naming the technique plainly, disclosing the verified runtime and renderer, auditing reference layers, carrying real numbers instead of adjectives, preserving owned staging, keeping expensive gotchas, declaring the boundary against neighbouring skills, and browser-verifying before claiming it works. Use when a page, canvas scene, shader, scroll effect, layout system, or hover interaction turned out well and should become a skill rather than staying in one project.

  • webgl-3d-object

    Create a real 3D WebGL object with geometric mesh depth, physically based material, directional and ambient lighting, perspective camera, subtle rotation, and floating motion. Use when a page needs a faceted 3D hero object or product-like visual with real lighting instead of CSS transform tricks.

  • webgl-laser

    Create a fixed full-screen WebGL laser background effect with a thin white-hot vertical core, restrained brand-colored halo, and soft smoky fog around the beam. Use only for laser background effects, not full page layout, copy, generic hero scenes, particles, or unrelated motion systems.

  • workflow-progress-screenshots

    Show the user real screenshots of the work as it progresses, without being asked. Capture the start, the key moment and the result of every visual change, send them as files with captions as soon as each is ready, and look at every image before sending it. Use on any task with a visible result (UI, pages, games, 3D, charts, motion), when the user says "show me", "screenshots", "keep giving me screenshots" or "where are the screenshots?", and before any report that claims a visual change works.

  • workflow-score-to-target

    Score work out of 10 against a clear rubric, then improve it round by round until every item reaches the target score the user named (for example "get it to 8 out of 10", "bring everything under 6 up to 6+"). Covers anchored rubrics, measurable criteria, independent or blind judging, before/after scorecards, and honest reporting of anything still short. Use whenever the user asks to score, rate, grade or judge something out of 10, names a target score, or asks "what would make this a 9?".

  • workflow-ship-change

    Ship every change the way the user requires, with the guardrails. Take screenshots of the start, the key moment and the result; give the change its own changelog version with pictures; verify with tests; commit only your own files; merge with the latest main and push as a fast-forward; publish that exact main live; confirm each step; and report measured sizes, asking before any upload over 50 MB. Use at the end of every change (feature, fix, tweak, art, balance, polish) and whenever the user says "ship it", "commit", "push", "merge", "publish", "deploy", "go live" or "update the changelog". Project specifics (hosting, the changelog pipeline, merge conflicts) go in an optional local references/<project>.md next to this skill.

  • workflow-threads-manager

    Oversee the other Claude threads (sessions) working on the same project. Check what each is doing, confirm finished work is merged to main, has its changelog entry with screenshots, and is live, archive threads that are truly done, and restart or flag threads that were cut off. Use when the user says "check threads", "check new changes", "are the threads merged and pushed", "archive the done threads", or asks what the other sessions are up to. Project specifics (changelog format, live site, capture folders) go in an optional local references/<project>.md next to this skill.

  • write-like-meng-on-x

    Write, rewrite, review, or continuously refine X/Twitter posts in Meng To's current voice using his deduplicated authored-post corpus, personal and product context, shared resources, and Content repo evidence. Use when asked to improve a tweet in Meng's tone, draft an original post, reply, thread, resource share, or quote post as Meng, check whether an angle repeats an earlier post, study Meng's writing style, ingest another 20-50 authored posts, or hone the reusable Meng X voice profile.

  • x-bookmark-quote-posts

    Check a user's latest X/Twitter bookmarks and turn recent saved posts into source-backed quote-post drafts calibrated against the user's latest 100 authored posts. Use when asked to review X bookmarks, create quote posts from bookmarks, refresh a bookmark quote queue, run a bookmark quote automation, study a user's X voice, or write first-person quote posts from X sources.
