Video & Animation

How to use the Imagine tools in Grok Build: imagine_text_to_image, imagine_image_to_image, imagine_reference_to_image, imagine_text_to_video, imagine_image_to_video, imagine_reference_to_video, and render_file for chat previews. When to build a visual with code instead of generating it, prompt-craft, reference-first handling of real people, factual grounding, and asset-consistency. Load this whenever generating or editing an image or video is on the table. Tool-usage-driven, not triggered by a user merely mentioning images.

Peer-to-peer realtime multiplayer over WebRTC data channels: every user of the deployed app connects directly to every other user (full mesh), the server only brokers the handshake at /api/rtc. Lowest possible latency, zero per-message server cost. Use for 2-8 player co-op/casual realtime: shared cursors, drawing, party games, casual action. Triggers: p2p, peer to peer, webrtc, low latency multiplayer, direct connection.

Use Neon Postgres (the database) in this TanStack Start app. Use when the app needs to store or query data, persist state, or keep per-user data. Triggers on "database", "Postgres", "Neon", "save data", "store data", "persist", "tables", "SQL", "query", "migrations".

Official Three.js API and TSL (Three.js Shading Language) reference for LLM code generation. Load when writing or debugging three.js / WebGL / WebGPU / custom materials / shaders / GLTF / advanced three APIs beyond basic game loop/controls. Prefer building-games for game correctness (loop, WASD, camera, orientation); use this skill for full API/TSL depth. Triggers on "three.js", "threejs", "WebGPU", "TSL", "NodeMaterial", "shader", "GLTF", "MeshStandard", "OrbitControls", "WebGLRenderer".

Generate and postprocess 2D game sprites and animation sheets: pixel-art characters, NPCs, creatures, spells, projectiles, impacts, props, summons, and transparent PNG/GIF exports. Use when building browser games that need real sprite sheets (not code-drawn placeholders), matching a map art style, or producing magenta-background sheets for chroma-key cleanup. Triggers on "sprite", "sprite sheet", "animation sheet", "pixel art character", "walk cycle", "attack animation", "projectile sprite", "2D game asset".

Share-link previews and app identity for apps on *.grok.me: the injector-owned og:image card, the SVG favicon, and PWA icons for installable apps. Use when scaffolding, renaming, or restyling the app — and for share / unfurl / OG / Twitter card questions. A custom 1200×630 card from the app's own art is the default — games of every kind (DOM board/word games included), whimsical apps, creative tools, and brand-forward pages; only plain utilities keep the placeholder. Always run the brand-asset pass as a `task` subagent and never wait for it. Triggers on "share", "rename", "app name", "OG", "Open Graph", "twitter card", "unfurl", "og:image", "og:type", "x:game:image", "x-banner", "link preview", "social card", "thumbnail", "preview image", "favicon", "app icon", "PWA", "manifest", "installable", "home screen", "SEO", "meta description".

Generate production-oriented 2D game maps with `imagine_text_to_image`: RPG/top-down maps, side-scroller parallax stages, tilemaps, layered raster maps, prop packs, collision zones, and walkable areas. Use when building browser games that need real map art (not pure code-drawn tiles), layered props, or map collision metadata. Triggers on "map", "level", "stage", "tilemap", "overworld", "dungeon", "side scroller background", "prop pack", "2D map".

Deep guide for game TILE assets: seamless tileable textures, terrain transition tilesets, autotiles, and ground/platform tiles. Use whenever generating tileable textures, tilesets, terrain transitions, or seamless patterns. Complements game-asset-core.

Player-facing input signs for browser games: WASD, vehicles, flight, FPS mouse-look, and the #1 failure mode (inverted A/D). Mandatory control self-tests and a tiny test interface so you can verify A turns left before shipping. Load for ANY game with movement, steering, flying, driving, tanks, boats, mechs, drones, planes, karts, third-person follow cams — not only racing. Triggers on "controls", "WASD", "inverted", "steer", "flight", "airplane", "kart", "vehicle", "yaw", "roll", "pitch", "mouse look", "A/D".

Deep guide for CHARACTER IDENTITY across images: turnarounds (front/side/ back), state and damage variants, palette swaps, equipment changes, and same-character-in-context sets. Use whenever generating character turnarounds, character sheets, variants of an existing sprite, or any same-subject multi-image set. Complements game-asset-core.

Build browser games and interactive/canvas/3D experiences in this TanStack Start + React app. Use for any game, simulation, or WebGL/Canvas experience — 2D or 3D, single-player. Covers the game loop & timing, 3D orientation/camera conventions, collision, performance, assets, audio, save, game feel, and per-genre playbooks. For WASD / vehicle / flight **input signs and inverted A/D**, open the **`controls`** skill — do not rely on this file or racing-kart alone. Triggers on "game", "minecraft", "fps", "platformer", "racing", "tetris", "snake", "shooter", "3d", "three.js", "canvas", "voxel", "physics".

Deep guide for game ANIMATION assets: motion cycles, action keyframes, effect sequences, and animation sprite sheets — built around a video-first pipeline. In this app-builder sandbox, execute via the video2dsprite / generate2dsprite skills (magenta + scripts), not ad-hoc ffmpeg. Use whenever generating anything that moves: walk/run cycles, attacks, idles, FX, flags, fire, animation sheets. Complements game-asset-core.

Animate a Stickman Kino film - write scenes.js from film.json/storyboard using the stickman engine (rigged stick figures with 58 poses and IK, ~190 props, charts and diagrams, kinetic text, captions, camera moves, effects, environments, themes, transitions), synced to the voice-over, then verify with check + snapshots. Use for any scene choreography, motion, layout or visual-fix work on a Stickman Kino film.

Remotion 代码驱动视频动画专业控制技能。用 React/TypeScript 代码精确控制2D动画，原生支持透明背景(Alpha通道)渲染，可输出WebM/MOV带透明通道视频，适用于剪映模板动画素材制作、UI动画、文字排版动画、角色2D动画等场景。提供API服务化、模板库、质量控制和自学习进化能力。

Add user accounts and sign-in to this TanStack Start app. Use when the app needs authentication, sign-in, user accounts, protected routes, or per-user data. Triggers on "auth", "login", "log in", "sign in", "sign up", "account", "users", "authentication", "protected", "who is logged in", "current user", "per-user".

End-to-end multi-tenant brand explainer/promo-video pipeline. Generates a complete branded video from a URL — extracts brand identity, writes script, generates voice + AI avatar + B-roll images + music underbed, assembles in HyperFrames, and renders. Trigger phrases include "Hyper Frames for <url>", "make a Hyper Frames video for <brand>", "Hyper Frames promo for <url>", "explainer video for <brand>", or just "Hyper Frames <url>".

End-to-end pipeline that takes a URL and produces a complete branded landing-page revision with a generated hero background video, then deploys it live to Netlify. Chains four steps with zero clarifying questions in between - brand book extraction (with GitHub publish), Nano Banana 2 + Seedance 2 video generation, frontend-design page build, and Netlify deploy. Trigger phrases - "animated website for <url>", "build an animated website from <url>", or "/animated-website <url>". Use when the user wants a viewable HTML landing page revision auto-generated and deployed from a reference URL for design comparison or rapid prototyping.

Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the animations", "audit the motion", "make this app feel better", or wants a roadmap of animation fixes rather than a review of a single diff.

为Seedance、即梦、小云雀、MiniMax H3等AI视频模型编写、审查或重构高精度中文视频提示词。适用于无参考图、首帧/首尾帧/尾帧驱动、多模态参考、参考图先行、连续运镜、动作匹配分镜、手机POV、人物微表演、对白同步、复杂物理运动与生成失败修复。

Build animations in React Native and Expo, making the decisions in the order that determines whether they feel right — should it animate, which thread it runs on, which properties, spring or timing, how the gesture hands off, how it degrades. Writes the implementation with Reanimated, Gesture Handler, Expo Router and expo-haptics. Use when animating anything in an Expo app, adding gestures, sheets, screen transitions, press feedback or haptics, or fixing motion that stutters on device. For web animation use `animate`.

Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations.
