僅限 Grok Build。將 2D 角色靜態圖轉換為流暢動畫精靈，透過影像生成/編輯基礎 → 影像轉影片 (6s/10s 原地動作) → ffmpeg 幀抽取 → magenta 色鍵去背 → 密集取樣精靈（條狀/網格/GIF）。當使用者需要影片轉精靈、從生成影片中進行動作捕捉、透過密集幀獲得流暢跑步/行走循環，或執行 /video2dsprite 時使用。

agent-sprite-forge 是什麼？

這是一個專門為 Grok Build 平台設計的 AI Agent 技能，用於從 2D 角色靜態圖生成流暢的動畫精靈。其核心工作流程為：先透過影像生成或編輯模型建立基礎影像，再使用 Grok Build 獨有的 image_to_video 功能生成 6 或 10 秒的原地動作影片，接著用 ffmpeg 抽取影片幀，並以 magenta 進行色鍵去背，最後從密集取樣的幀中輸出精靈條狀圖、網格圖或 GIF 動圖。此技能解決了傳統手工繪製動畫精靈費時費力的痛點，特別適合需要影片轉精靈、動作捕捉、或更流暢跑步/行走循環的場景。**重要限制**：僅能在 Grok Build 上使用，因為其他平台（如 Codex、Claude）缺乏 image_to_video 功能。若使用者不需要影片中間步驟，直接生成清晰像素圖時，建議改用 generate2dsprite 技能。

agent-sprite-forge 是做什麼的？

僅限 Grok Build 使用。透過影像生成/編輯基礎 → 影像轉影片（6s/10s 原地動作）→ ffmpeg 幀抽取 → magenta 色鍵去背 → 密集取樣精靈（條狀/網格/GIF），將 2D 角色靜態圖轉換為流暢動畫精靈。當使用者需要影片轉精靈、從生成影片中進行動作捕捉、透過密集幀獲得流暢跑步/行走循環，或執行 /video2dsprite 時使用。請勿在 Codex/Claude 上使用 — 僅有 Grok Build 具備 image_to_video 功能。若無需影片步驟，偏好直接生成清晰像素圖時，請優先使用 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.
