Media Generation, Vision, and Video

Choose the right path

• - Image generation or editing: use the preferred Nano Banana 2 / Gemini image workflow.
• Image understanding / screenshot analysis: use Gemini multimodal image understanding.
• Video generation: use Google Veo 3.1.

Non-negotiables

• - Prefer Google-native media models and official flows first.
• Preserve aspect ratio, resolution, style, and reference-image constraints.
• Do not guess image contents when a multimodal path is available.
• Do not claim video generation succeeded unless a real video file was produced.
• When delivering files, send the generated asset directly into the conversation when supported.
• For successful image or video generation, always deliver the actual media asset to the chat; do not stop at a summary or path when direct sending is available.

Image generation and editing

• - Use the preferred image tool path first.
• For edits, keep the user’s reference image identity intact unless explicitly asked to change it.
• If the user specifies size or ratio, honor it exactly when possible.
• If the task asks for multiple variants, generate a small set rather than one-by-one loops.

Image understanding

• - Use multimodal analysis for screenshots, photos, and UI inspection.
• Report only what is visible or strongly supported.
• Separate confirmed observations from inference.
• If the image is unreadable or only partially visible, say so plainly.

Video generation

• - Default to Veo 3.1.
• Prefer the official Gemini API workflow when possible.
• Save the final file with a stable filename before sharing it.
• If video output is not available in the current environment, say that clearly and identify the blocker.
• Do not substitute a still image or text summary for an actual video file unless the user accepts that fallback.

Delivery and reporting

• - Return the generated asset when available.
• If the user asks for a file, do not bury it in prose—attach or send it directly.
• Keep the response short: result, file/path if any, and blockers if any.
