nano-banana-pro-pptx: AI-Generated Image Presentations

Generate a PowerPoint presentation where every slide is a single full-bleed AI-generated image. Gemini handles both the narrative planning and image generation end-to-end.

Usage

Run the script using absolute path (do NOT cd to skill directory first):

CODEBLOCK0

Arguments

The script checks for API key in this order:

1. 1. --api-key argument (use if user provided key in chat)
2. INLINECODE14 environment variable

If neither is available, the script exits with an error message.

The script checks for base URL in this order:

1. 1. --base-url argument (use if user provided URL in chat)
2. INLINECODE16 environment variable

If neither is available, the script uses the default Gemini API base URL.

Instructions

1. 1. Always use the absolute path to the script — never cd to the skill directory
2. INLINECODE18 is always required — ask the user if not provided
3. Default to --resolution 1K for drafts; suggest 2K for final output
4. Omit --filename to let the script auto-generate a slug from the prompt (do not construct the filename yourself)
5. Confirm the output file path to the user after completion
6. If GEMINI_API_KEY is not set in the environment, remind the user to set it or pass INLINECODE23

Workflow

1. 1. Draft at 1K resolution to verify narrative and composition
2. Regenerate at 2K or 4K for final delivery

Environment Variables

• - GEMINI_API_KEY — required (or pass --api-key)
• INLINECODE29 — optional, for custom/proxy endpoints
