Overview

面向 2D 游戏生产可直接进入后续美术流程的素材草图与半成品，重点覆盖：

1. 单体素材：图标、道具、武器、金币、宝箱、药水、UI 小物件
2. 角色素材：角色立绘、敌人概念图、NPC 半身或全身设定
3. 网格素材：四宫格/九宫格 sprite sheet、简易动作帧、tileset 草图
4. 资产整理：透明底导出、宫格拆分、清晰度增强、局部重绘

本 Skill 的目标不是做完整游戏场景原画、3D 建模或复杂骨骼动画，而是为游戏策划、美术和独立开发者快速产出可迭代的 2D 资产基础稿。

Dependencies

• tools: meitu-cli
  • text-to-image - 从文字生成单体素材、角色概念、sprite sheet 或 tileset 草图
  • image-edit - 基于参考图做局部修改、延续风格批量变体、修正细节
  • image-cutout - 将生成结果抠成透明底素材
  • image-grid-split - 将 sprite sheet / 宫格图拆成独立帧
  • image-superres-enhance - 对低分辨率素材做超分和锐化增强
• credentials: 美图 AI 开放平台 API 凭证
  • 环境变量：MEITU_OPENAPI_ACCESS_KEY / MEITU_OPENAPI_SECRET_KEY
  • 或配置文件：~/.meitu/credentials.json
  • 验证：meitu auth verify --json
• workspace (optional): {OPENCLAW_HOME}/workspace/visual/
  • Not found -> skip all knowledge reads, skill works without it

路径别名：下文中 $VISUAL = {OPENCLAW_HOME}/workspace/visual/

Core Workflow

Preflight -> [Context] -> Execute -> Refine -> Deliver -> [Record]
             ^ 创意型任务执行                  ^ 项目模式时执行
             ^ 一次性模式跳过 Context         ^ 一次性模式跳过

Preflight

1. meitu --version -> 未安装则提示 npm install -g meitu-cli
2. meitu auth verify --json -> 凭证无效则引导配置
3. Detect mode: cwd has openclaw.yaml -> project mode; else -> one-off can_record = cwd 有 openclaw.yaml AND $VISUAL 存在（两者缺一即 false）
4. Resolve output_dir: openclaw.yaml -> ./output/ | else -> $VISUAL/output/meitu-game-2d-assets/ mkdir -p {output_dir}
5. 解析用户需求中的最少资产规格：
   • asset_type：icon | prop | character | enemy | tileset | sprite-sheet
   • style：pixel | flat-vector | hand-painted | chibi-cartoon | retro-rpg | custom
   • ratio：未指定时按素材类型自动补默认值
