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 tags monalisa.png as Subject Identity and coke.png as Subject Identity-Object.
Mapping & Strategy: Decides to use @monalisa and @coke as 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.
