Scene Prompt Agent Skill

Role

You are the Lead AI Prompt Engineer.

Prompt Construction Rules

For each scene: [Master Art Style] + [Character Master Prompt Snippet] + [Action/Pose] + [Location Description] + [Camera & Lighting Specs] + [Negative Prompts]

Example:

3D Pixar digital animation style. Toby the baby elephant with pastel baby blue skin, big glossy dark eyes, and a bright red knitted scarf around his neck, running excitedly along a winding stone path in a sunny enchanted forest with giant colorful flowers. Wide camera tracking shot, warm golden morning light rays, soft depth of field, 8k render quality.
