## What it does

The skill teaches prompt writing for Nano Banana, Google’s Gemini image model. It covers quote graphics, carousel slides, thumbnails, infographics, product scenes, backgrounds, and ads. Prompts describe the subject, framing, light, style, constraints, and exact copy instead of relying on keyword piles. Platform aspect ratios are part of the recipe.

It reads `brand-profile.md`, uses reference images to keep a set visually aligned, and supports conversational edits for seasonal or regional variants. For image text, the workflow fixes the copy first and checks the rendered spelling afterward. API details, authentication, and the WoopSocial Media upload flow live in `tools/integrations/nano-banana.md`; WoopSocial itself does not generate the image.

Generated images carry a SynthID watermark and need an AI disclosure. The skill refuses identifiable real people and copyrighted characters or logos. Typography-led layouts and surreal fine-art work are directed to other models, while Nano Banana is used for its Gemini image workflow.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add social-media-skills/skills --skill nano-banana -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nano-banana/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nano-banana/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add social-media-skills/skills --skill nano-banana -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nano-banana/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add social-media-skills/skills --skill nano-banana -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nano-banana/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install social-media-skills/skills nano-banana
```

2. **Manually: put the files in place**
- File: `.github/skills/nano-banana/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add social-media-skills/skills --skill nano-banana -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/social-media-skills/skills --path skills/nano-banana
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nano-banana/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add social-media-skills/skills --skill nano-banana -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/social-media-skills/skills/tree/HEAD/skills/nano-banana/SKILL.md

## When to use it
- write a prompt for a social post image
- keep a brand style across an image set
- place and verify copy inside an image
- choose an aspect ratio for a platform
- edit a hero image for a seasonal variant

## Example prompts
- Write a quote-graphic prompt using the colours and visual rules in `brand-profile.md`, then tell me how to check the rendered text.
- Create a carousel set with reference images and a locked visual style; change the content while keeping the rest consistent.
- Turn this product image into a seasonal variant and point me to the API and upload steps in `tools/integrations/nano-banana.md`.

  Use to write great prompts for Nano Banana (Google's Gemini image model: Nano Banana Pro = Gemini 3
  Pro Image) to generate or edit images for social media — the image-prompt-craft mini-skill. Run when
  the user wants a nano-banana / Gemini image prompt, an AI image for a post (quote graphic, carousel
  slide, thumbnail, infographic, product shot, ad creative), or conversational image editing. Reads
  brand-profile for brand colours/style. Strengths: best-in-class legible in-image text (route
  typography/layout-led design to ideogram), multi-image consistency, conversational editing, and
  Google's photoreal lane (Imagen deprecated); surreal art stays Midjourney's. Teaches prompt anatomy,
  the text-first approach, reference-image consistency, and per-platform aspect ratios. Honest: SynthID
  watermark + AI disclosure; never real identifiable people or copyrighted characters/logos; verify
  spelling/data. The API/connection and WoopSocial upload flow live in tools/integrations/nano-banana.md.

# 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**.
```
