How it works
sprite-animation-assets
When your agent uses it
Plan, generate, QA, and package continuous raster animation frame sets, GIF previews, and transparent spritesheet atlases. Use when the user asks for a GIF animation, animation frames, sprite rows, web/game animation assets, or reusable visual animation materials.

# Sprite Animation Assets
## 核心判断
动画素材的关键不是“单张图好看”,而是同一个角色或物体在每一帧里保持身份一致、尺寸一致、背景透明、动作能循环。先定义帧规格和状态,再逐组生图,最后用脚本组装和验收。
适合输出:连续帧 PNG、单状态 GIF、透明 spritesheet、固定网格 atlas、网页/游戏动画素材。
不适合输出:单张透明素材;这类转给 `$transparent-visual-assets`。
## 工作流
1. 定义规格:状态名、每个状态帧数、画布尺寸、输出格式。
2. 生成或确认一张 canonical base image,作为所有帧的身份锚点。View the complete source on GitHubtransparent-visual-assets
When your agent uses it
Generate transparent-background raster assets with Codex image generation plus deterministic cleanup. Use when the user wants a PNG sticker, icon, mascot, sprite, UI asset, or web-ready visual element with transparent background, or asks to remove/avoid a generated image background while preserving the subject.

# Transparent Visual Assets
## 核心判断
先让 Codex 生图得到“容易抠干净”的图,再用脚本做确定性清理。不要要求模型直接画棋盘格透明背景;棋盘格会变成图像内容。优先让模型使用纯色背景,例如 `#FF00FF` 或 `#00FF00`,并明确主体不能使用接近背景的颜色。
适合输出:透明 PNG、网页素材、贴纸、图标、单帧 sprite、角色/物体素材。
不适合输出:多帧动画、spritesheet、视频;这些转给 `$sprite-animation-assets`。
## 典型使用场景
- 网站设计素材:Landing page、产品官网、博客插画、功能区装饰、空状态插画。
- PPT / 汇报图表:路演页、数据页、业务复盘、图表旁的视觉解释元素。View the complete source on GitHubSkills included
