modbender Seedance 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.
Core Workflow
This skill follows a strict three-phase workflow. The output of each phase is the input for the next.
| Phase | Goal | Key Actions | Output |
|---|---|---|---|
| 1. Recognition | Understand user input | Parse intent, analyze assets, tag with atomic roles | recognition_output.json |
| 2. Mapping & Strategy | Design an executable reference strategy | Determine optimal reference method (Text, Asset, Hybrid) | strategy_output.json |
| 3. Construction & Assembly | Generate the final, complete prompt | Assemble text, append @-syntax, consult templates | final_prompt.json |
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's Internal Process:
- Recognition: Identifies
action_intent("drink a Coke"),style_intent("cinematic, close-up"), and tagsmonalisa.pngasSubject Identityandcoke.pngasSubject Identity-Object. - Mapping & Strategy: Decides to use
@monalisaand@cokeas asset references and the rest as text prompts. - Construction & Assembly: Assembles the final prompt.
Final Output:
{
"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. Must be consulted during Phase 1 and Phase 2./references/seedance_syntax_guide.md: Seedance 2.0 "@asset_name" syntax reference. Must be consulted during Phase 3 to ensure correct syntax generation./references/prompt_templates.md: Advanced prompt templates for different genres (e.g., Cinematic, Product Showcase, Narrative). Optional consultation during Phase 3 for stylistic enhancement.
