# 手势对齐｜前景动作触发后景状态

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

## Workflow

1. Read [references/summary.md](references/summary.md) for fit, input slots, and the concise starting example.
2. Read [references/template.md](references/template.md) completely before drafting.
3. Preserve the user's subject and objective, then fill every missing scene, trigger, event-chain, camera, sound, and payoff slot.
4. Treat these anchors as mandatory:

- Establish one stable subject-target geography and one readable baseline state before the effector enters.
- Use one unambiguous effector path that ends in a clean foreground-to-background alignment with the target.
- Change exactly one target state during or immediately after the alignment, without asserting literal contact that is not shown.
- End on the persistent changed state with one brief acknowledgment or recall gesture, not a second state change.

5. Change source-specific people, setting, props, palette, dialogue, shot boundaries, sound family, and payoff surfaces together.
6. Compile MiniMax H3 and Seedance 2.0 independently; do not leak one model's field syntax into the other.
7. Silently verify anchor coverage, continuity, timing, physical causality, and anti-copy distance before returning the final prompts.

## 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 stable subjects once and preserve event order, camera motivation, sound intent, and overall duration.
- Use a simple paragraph for simple concepts or an ordered multi-shot structure for complex concepts.
- State overall duration once; do not copy H3 field labels or per-shot timecode grammar.

## Output

Return one concept sentence, the 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. Preserve that subject and complete the mechanism instead of returning a generic portrait or showcase.
- Do not omit, reorder, or weaken a required anchor.
- Do not reuse source people, brands, dialogue, exact storyboard, signature props, exact timings, or recognizable effect surfaces.
