Scene / Background Image Generation

Generate realistic background/scene images via Renoise nano-banana-2 model for use as video environment references.

Arguments

• First argument — Scene description in natural language (required)
• Second argument — Output directory (required)

Instructions

1. Write an English prompt describing the scene. The prompt should specify:

   • Environment and setting details
   • Lighting conditions
   • Perspective (e.g. "shot from a natural handheld perspective")
   • "No people, no hands, no products — just the empty environment"
   • "Photorealistic, like a real photograph. Sharp focus on the main surface area."

2. Generate the image using the renoise-gen CLI:

node ${CLAUDE_SKILL_DIR}/../renoise-gen/renoise-cli.mjs task generate \
  --model nano-banana-2 \
  --prompt "<english_prompt>" \
  --resolution 2k \
  --ratio 9:16

3. The command will output an imageUrl when complete. Download the image to the output directory:

curl -sL "<imageUrl>" -o "<output_dir>/scene.png"

4. Verify the file was created and print file size.

5. Show the generated image to the user for approval. If not satisfactory, adjust the prompt and regenerate.
