What this skill does


# Gemini Image Simple

Generate and edit images using Google's **Nano Banana Pro** (Gemini 3 Pro Image) - the highest quality image generation model.

## Why This Skill

| Feature | This Skill | Others (nano-banana-pro, etc.) |
|---------|------------|-------------------------------|
| **Dependencies** | None (stdlib only) | google-genai, pillow, etc. |
| **Requires pip/uv** | ❌ No | ✅ Yes |
| **Works on Fly.io free** | ✅ Yes | ❌ Fails |
| **Works in containers** | ✅ Yes | ❌ Often fails |
| **Image generation** | ✅ Full | ✅ Full |
| **Image editing** | ✅ Yes | ✅ Yes |
| **Setup complexity** | Just set API key | Install packages first |

**Bottom line:** This skill works anywhere Python 3 exists. No package managers, no virtual environments, no permission issues.

## Quick Start

```bash
# Generate
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "A cat wearing a tiny hat" cat.png

# Edit existing image  
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "Make it sunset lighting" edited.png --input original.png
```

## Usage

### Generate new image

```bash
python3 {baseDir}/scripts/generate.py "your prompt" output.png
```

### Edit existing image

```bash
python3 {baseDir}/scripts/generate.py "edit instructions" output.png --input source.png
```

Supported input formats: PNG, JPG, JPEG, GIF, WEBP

## Environment

Set `GEMINI_API_KEY` environment variable. Get one at https://aistudio.google.com/apikey

## How It Works

Uses **Nano Banana Pro** (`nano-banana-pro-preview`) - Google's highest quality image generation model:
- Pure `urllib.request` for HTTP (no requests library)
- Pure `json` for parsing (stdlib)
- Pure `base64` for encoding (stdlib)

That's it. No external packages. Works on any Python 3.10+ installation.

## Model

Currently using: `nano-banana-pro-preview` (also known as Gemini 3 Pro Image)

Other available models (can be changed in generate.py if needed):
- `gemini-3-pro-image-preview` - Same as Nano Banana Pro
- `imagen-4.0-ultra-generate-001` - Imagen 4.0 Ultra
- `imagen-4.0-generate-001` - Imagen 4.0
- `gemini-2.5-flash-image` - Gemini 2.5 Flash with image gen

## Examples

```bash
# Landscape
python3 {baseDir}/scripts/generate.py "Misty mountains at sunrise, photorealistic" mountains.png

# Product shot
python3 {baseDir}/scripts/generate.py "Minimalist product photo of a coffee cup, white background" coffee.png

# Edit: change style
python3 {baseDir}/scripts/generate.py "Convert to watercolor painting style" watercolor.png --input photo.jpg

# Edit: add element
python3 {baseDir}/scripts/generate.py "Add a rainbow in the sky" rainbow.png --input landscape.png
```

watch

Included

Watch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.

physical-ai-defect-image-generation

Included

Use when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment.

accelint-react-best-practices

Included

React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.

generating-mermaid-diagrams

Included

Salesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
