Image Generation Skill
This skill generates an appropriate cover image for the radio show based on a prompt, using the Gemini 3 Flash Image model, with a fallback to the Gemini 3 Pro Image model ("Nano Banana Pro") if needed.
Requirements
- Python 3.10+
google-genai Python package (>= 2.0.1)
Instructions
-
Generate an image (Recommended: use the metadata file directly):
python3 skills/cover-image-generation/scripts/generate_image.py \
--workspace ./workspace \
--metadata ./workspace/data/show_notes.json
Note: Using --metadata will automatically extract the show title and apply a random, high-quality prompt template. This is the preferred method.
Alternative (Manual prompt):
python3 skills/cover-image-generation/scripts/generate_image.py \
--workspace ./workspace \
--prompt "A prompt describing the image"
-
Output:
- The image will be saved to
{workspace}/images/cover.png.
Model
- Primary Model:
gemini-3.1-flash-image
- Fallback Model:
gemini-3.1-pro-image
- Resolution: 1:1 (default)
Prompting rules
When using the --metadata option, this skill uses a set of predefined prompt templates and selects one at random to generate cover images. It dynamically inserts the show title into the selected template.
- Example Prompt:
"A professional podcast cover image for a show titled 'AI Talk Radio' on the 'AI Talk Radio' station. The design features the text 'AI Talk Radio' in a bold, stylish white font centered on the cover. The background is a vibrant purple with a textured water ripple effect that covers the entire frame, creating a dynamic and clean aesthetic."
If you choose to use the --prompt option instead, you must construct the prompt yourself. In that case, follow these rules:
Forbidden themes
- Do not ask for futuristic, cyberpunk or neon themes
- Do not include any text other than the show title
