name	hand-bounded-local-medium-window
description	Create original short videos using the 手势边界换媒｜局部窗口、多形态验真与回归 Creative DNA for MiniMax H3 or Seedance 2.0. Use when the user wants a hand-defined local medium window, repeated geometry proof, strict clipping, and a controlled return with new subjects and surfaces.

手势边界换媒｜局部窗口、多形态验真与回归

Create a new execution from the reusable mechanism, not a surface reskin of any reference video.

Workflow

1. Read references/summary.md for fit, input slots, and the concise starting example.
2. Read references/template.md completely before drafting.
3. Preserve the user's subject and objective, then fill every missing adult identity, environment, boundary, alternate medium, proof region, apex, release, and sound slot.
4. Treat these anchors as mandatory:

• 激活前先建立一名明确成年原创控制者、稳定环境和可见的空闲双手。
• 双手几何必须先于换媒形成，活动边缘始终绑定指尖或手部边线。
• 替代媒介严格限制在移动边界内部，边界两侧空间精确注册，外部保持基线状态。
• 至少用三种几何或覆盖区证明同一规则；最大覆盖留到后段，再主动收回并以原媒介反应或残留确认结束。

5. Change source-specific people, wardrobe, environment, edge styling, exact gestures, timing, reaction, and sound family together.
6. Compile MiniMax H3 and Seedance 2.0 independently; do not leak one model's field syntax into the other.
7. Silently verify hand-before-effect causality, edge registration, clipping, geometry variation, late apex, baseline return, and anti-copy distance.

MiniMax H3

• Use the current official H3 task grammar and language profile.
• Separate integrated visual action, overall soundscape, and non-diegetic music or explicit silence.
• Use timestamps only to make event order executable; keep shots consecutive and duration-safe.

Seedance 2.0

• Define one stable adult identity and one stable environment before the aperture activates.
• Use ordered shots for the geometry proofs and release.
• State overall duration once; do not copy H3 field labels or per-shot timecodes.

Output

Return one concept sentence, filled slots, an anchor-coverage check, one MiniMax H3 prompt, one Seedance 2.0 prompt, and a short anti-copy validation note.

Non-Negotiable

• A subject-only request is underspecified; complete the environment, boundary, alternate medium, proof, apex, and return slots.
• Do not let the alternate medium leak outside the boundary or drift across the registration edge.
• Do not reuse source people, exact styling, exact gestures, exact sequence, or recognizable effect surfaces.
