# 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:

`references/when-and-how-to-prompt.md`.)

## Step 0 — Read the brand + the job

Load `brand-profile.md` (colours, visual style, do/don't). Identify the **job** (quote graphic /

carousel / thumbnail / infographic / product shot / background / ad / edit) and the **platform

aspect ratio**.

## Step 1 — Write the prompt (natural language, not keyword spam)

Describe, don't pad. Include **subject · composition/camera · action/context · lighting/atmosphere ·

style/medium · constraints + exact text**. Drop "4k, masterpiece, trending on artstation" tokens —

modern Gemini models reason over natural language. Bake in the **brand** palette/style. Set the

**aspect ratio**. Iterate cheap at 1K, finalize at 2K/4K. See `references/when-and-how-to-prompt.md`.

## Step 2 — Use the superpowers deliberately

- **Text:** put the **exact words in quotes** + font + placement; settle the **copy first** (the

text-first approach), keep it short, and **verify the spelling** in the output.

- **Consistency:** use **reference images** and a **locked style description**; generate a set **one at

a time** ("everything the same except X"); hold the aspect ratio; review for drift.

- **Editing:** natural-language changes to a hero image for locale/seasonal/A-B variants.

See `references/text-and-consistency.md`.

## Step 3 — Pick the recipe

Adapt a pattern for the job (quote graphic, carousel set, thumbnail, infographic, product/lifestyle,

background, ad), with the right aspect ratio and brand grounding. See `references/social-recipes.md`.

## Step 4 — Verify, disclose, ship

- **Verify** rendered text and any infographic **data** before publishing (the model can misspell /

misplace facts).

- **Disclose** AI generation per platform/region (Meta "Made with AI", EU AI Act); every image carries

a **SynthID** watermark (+ C2PA) — don't strip it or pass the image off as a non-AI photo.

- **Ship:** generate per the integration guide → **upload bytes to WoopSocial Media → attach to the

post** via `scheduling-and-queue`. WoopSocial doesn't generate images.

## Quality bar — self-check

- Did I **match the tool to the job** (and say when to use another model)?

- Is the prompt **natural-language and specific** (subject/composition/lighting/style/text), **brand-

grounded**, with the **right aspect ratio**?

- For text: **exact words in quotes** + font + placement, **copy-first**, **spelling verified**?

- For sets: **references + locked style**, one-at-a-time, reviewed for drift?

- Did I handle **SynthID + disclosure**, **verify text/data**, and **refuse real people / IP**?

- Did I point to **`tools/integrations/nano-banana.md`** for the API + WoopSocial flow (no claim that

WoopSocial generates images)?

## Edge cases & pushback

- **Photoreal headshot / surreal art** → suggest the better-fit model; don't force Nano Banana.

- **"logo, 4k, masterpiece, trending…"** → rewrite into a specific scene description; drop token spam.

- **Real person / copyrighted character / brand style** → refuse; offer an original alternative.

- **"Post it as a normal photo"** → SynthID + disclosure; don't disguise AI imagery.

- **Long paragraph of in-image text** → expect errors; shorten + verify (or finish in a design tool).

- **"Generate it in WoopSocial"** → WoopSocial doesn't generate; this skill prompts the model, then the

image is uploaded to Media and attached.
