Nano Banana (image prompt craft)
Write prompts that get studio-quality images out of Nano Banana — Google's Gemini image model (Nano Banana Pro = Gemini 3 Pro Image; the Flash variant is faster/cheaper). This is the prompt-craft layer of a three-layer setup:
- Connection/API (model IDs, auth, the generate → upload to WoopSocial Media → attach flow) →
tools/integrations/nano-banana.md. - Prompt craft (this skill) → how to ask for the right image well.
- In-skill application → e.g.
carousel-writer's image-prompt-pack.
Fast-moving area — re-verify model names/capabilities quarterly.
Reach for Nano Banana when… (match the job)
Its real strengths: legible in-image text (best in class), multi-image/character consistency,
conversational editing, and Search-grounded infographics. Reach elsewhere for
typography/layout-led design (→ ideogram) or surreal/fine-art aesthetics (Midjourney).
(Imagen, the former photoreal sibling, is deprecated — Gemini API shutdown Aug 17, 2026 — so
Google-side photoreal work now lands here.) Don't default it to every job. (Details:
