Grok Build 专用技能。将 2D 静态角色通过图像生成/编辑 → 图像转视频 (6秒/10秒原地循环) → ffmpeg 抽帧 → magenta 色键抠像 → 密集采样精灵图 (条状/网格/GIF) 转化为流畅动画精灵。

agent-sprite-forge 是什么？

这是专为 Grok Build 平台设计的精灵动画生成工具。它能将任意 2D 静态角色图像通过自动化流水线转化为流畅的动画精灵序列：首先使用图像生成或编辑 API 创建基础角色图，然后通过 image_to_video 模型生成 6 秒或 10 秒的原地循环动画视频，接着利用 ffmpeg 抽帧并借助 magenta 库进行色键抠像，最终输出密集采样的精灵条、网格或 GIF 动画。该技能特别适合需要从生成的视频中提取运动数据、制作更平滑的奔跑/行走循环动画、或执行 /video2dsprite 命令的场景。请注意，它仅适用于 Grok Build 平台（因依赖 image_to_video 功能），不可用于 Codex 或 Claude。若用户需要清晰的像素风格的精灵工作表（无需视频中间步骤），建议优先使用 generate2dsprite 技能。

agent-sprite-forge 是做什么的？

Grok Build 专用。通过图像生成/编辑基础 → 图像转视频 (6秒/10秒原地循环) → ffmpeg 抽帧 → magenta 色键抠像 → 密集采样精灵图 (条状/网格/GIF) 将 2D 静态角色转化为流畅动画精灵。适用于用户需要视频转精灵、从生成视频中捕获运动、从密集帧中制作更平滑的奔跑/行走循环、或运行 /video2dsprite 时。请勿在 Codex/Claude 上使用——仅有 Grok Build 支持 image_to_video。若需无需视频的清晰像素精灵工作表，建议优先使用 generate2dsprite。

Grok Build ONLY. Turn a 2D character still into smooth animation sprites via image_gen/image_edit base → image_to_video (6s/10s run-in-place) → ffmpeg frames → magenta chroma-key → dense sampled sprites (strip/grid/GIF). Use when the user wants video-to-sprite, motion capture from generated video, smoother run/walk cycles from dense frames, or runs /video2dsprite. Do NOT use on Codex/Claude — only Grok Build has image_to_video. Prefer generate2dsprite for crisp pixel sheets without video.
