Generate Nanobanana

Overview

generate-nanobanana calls Google's Gemini media models directly through the Gemini API — no third-party routing layer — to generate and edit images and video. It routes each request to the right model tier (draft, standard, quality, or video), loads real reference images instead of relying on text descriptions, gates every paid call behind explicit user approval, and writes a JSON sidecar next to every output recording the exact prompt, model, and cost. It registers a single /generate command.

This skill adapts the workflow (model routing, reference-image handling, sidecar logging) from AntonioCardenas/generate-nanobanana. The actual request shapes in references/ were independently verified against the live Gemini API docs rather than copied from that upstream repo, whose examples predate Google's migration to the Interactions API and use stale, non-functional request methods. Model IDs, request contracts, and pricing all change on Google's own schedule — re-verify against the docs linked from each reference file before relying on this skill in a new session.

When to Use This Skill

• Use when the user asks to generate, create, or make an image or video, or wants a thumbnail.
• Use when the user wants to animate a still image, or says "generate on brand" or "generate from reference".
• Use when the user wants to link or import a folder of reference images (logos, faces, product shots) for reuse across generations.
• Use when the user invokes /generate or /generate frf <set>, even without naming a specific model.
