name: 3d-cloth-material
description: 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.

name: 3d-falling-leaves
description: 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.

name: 3d-four-seasons
description: 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.

name: 3d-high-poly-models
description: 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.

---
name: 3d-high-resolution-textures
description: 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.

name: 3d-orbit-inspect-demo
description: 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.

name: 3d-paper-material
description: 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.

name: 3d-retina-resolution
description: 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.

name: 3d-sky-background
description: 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.
---

• SKILL.md

---
name: 3d-sky-rays
description: 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.

---
name: 3d-ultra-realistic-water
description: 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.

---
name: 3d-virtual-tour
description: 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.

name: 3d-wood-lighting-scorecard
description: 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".

---
name: 3d-wood-material
description: 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.

name: codex-gpt-image-2-5-flare
description: Generate or edit artwork with built-in Codex image gen, especially transparent PNG ornaments, game sprites, emblems, and UI graphics. Use when the user requests GPT 2.5 Flare, /codex-gpt-image-2-5-flare, or this built-in transparent-asset workflow. Includes alpha verification, prompt preservation, and optional project integration.

name: game-dev-combat-animation
description: 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.

name: game-dev-combat-skill-polish
description: 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.

name: horizontal-scroll-scenes
description: 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.

name: paper-cinder-transition
description: 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.

name: workflow-progress-screenshots
description: 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.

---
name: workflow-score-to-target
description: 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?".

name: workflow-ship-change
description: 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.

name: workflow-threads-manager
description: 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.
