Seedance 2.0 Prompter

# Seedance 2.0 Prompt Designer Skill

This skill transforms a user's scattered multimodal assets (images, videos, audio) and ambiguous creative intent into a structured, executable prompt for the Seedance 2.0 video generation model. It acts as an expert prompt engineer, ensuring the highest quality output from the underlying model.

## When to Use

- When the user provides multiple assets (images, videos, audio) for video generation.
- When the user's request is complex and requires careful prompt construction.
- When using the Seedance 2.0 model for video generation.

## Core Function

This skill analyzes all user inputs and generates a single, optimized JSON object containing the final prompt and recommended parameters. The internal workflow (Recognition, Mapping, Construction) is handled automatically and should not be exposed to the user.

## Usage Example

**User Request:** "Make the Mona Lisa drink a Coke. I want it to feel cinematic, like a close-up shot."
*User uploads `monalisa.png` and `coke.png`*

**Agent using `seedance-2.0-prompter`:**
*The agent internally processes the request and assets, then outputs the final JSON to the next skill in the chain.*

**Final Output (for internal use):**
```json
{
  "final_prompt": "A cinematic close-up shot of a woman picking up a bottle of Coke and taking a sip. The scene is lit with dramatic, high-contrast lighting. Use @monalisa as the subject reference, and the object appearing in the video is @coke.",
  "recommended_parameters": {
    "duration": 8,
    "aspect_ratio": "16:9"
  }
}
```

## Knowledge Base

This skill relies on an internal knowledge base to make informed decisions. The agent MUST consult these files during execution.

- **`/references/atomic_element_mapping.md`**: **Core Knowledge**. Contains the "Asset Type -> Atomic Element" and "Atomic Element -> Optimal Reference Method" mapping tables.
- **`/references/seedance_syntax_guide.md`**: Seedance 2.0 "@asset_name" syntax reference.
- **`/references/prompt_templates.md`**: Advanced prompt templates for different genres (e.g., Cinematic, Product Showcase, Narrative).


# Atomic Element Mapping Knowledge Base

This document provides the core logic for the Seedance Prompt Designer skill. It contains two critical mapping tables.

## Table 1: Asset Type -> Potential Atomic Elements

This table maps the type of user-uploaded asset to the most likely atomic element roles it can play in video generation. The skill should use this table in **Phase 1** to analyze uploaded assets.

| Asset Type (Heuristic) | Potential Atomic Element(s) |
| :--- | :--- |
| Image with a clear human/character face | Subject Identity, Aesthetic Style |
| Image of an object/product | Subject Identity (Object) |
| Image of a landscape/environment | Scene Environment, Aesthetic Style |
| Image with strong artistic style (e.g., painting, sketch) | Aesthetic Style |
| Image with clear compositional structure | Composition / Layout |
| Video with a character performing an action | Subject Motion, Subject Identity |
| Video with significant camera movement | Camera Language |
| Video with prominent visual effects | Visual Effects |
| Audio file with speech | Voice (Timbre) |
| Audio file with music | Non-speech (Music) |
| Audio file with sound effects | Non-speech (Sound Effect) |

## Table 2: Atomic Element -> Optimal Reference Method

This table defines the best way to reference each atomic element when constructing the prompt. The skill must use this table in **Phase 2** to design the reference strategy.

| Atomic Element | Optimal Method | Rationale |
| :--- | :--- | :--- |
| **Subject Identity** | **Asset** | High information density. Must
