What this skill does


# NVIDIA Image Generation

Generate and edit images using NVIDIA's FLUX models.

## Models

| Model | Use Case | Speed | Quality |
|-------|----------|-------|---------|
| `dev` | High-quality text-to-image | Normal | Best |
| `schnell` | Fast text-to-image | Fast | Good |
| `kontext` | Image editing | Normal | Best |

## Quick Start

```bash
# Generate an image
python scripts/generate.py "A cute cat in space"

# Edit an existing image
python scripts/generate.py "Add sunglasses" -i photo.jpg -o edited.png
```

## Parameters

### Text-to-Image (dev/schnell)

| Parameter | Short | Default | Description |
|-----------|-------|---------|-------------|
| `prompt` | | (required) | Text description |
| `-o, --output` | | output.png | Output file path |
| `--width` | | 1024 | Output width in pixels |
| `--height` | | 1024 | Output height in pixels |
| `--aspect-ratio` | `-ar` | 1:1 | Aspect ratio preset |
| `--steps` | `-s` | 30 | Diffusion steps |
| `--seed` | | 0 | Random seed (0=random) |
| `--model` | `-m` | auto | Model selection |

### Image Editing (kontext)

| Parameter | Short | Default | Description |
|-----------|-------|---------|-------------|
| `prompt` | | (required) | Edit instruction |
| `-i, --input` | | (required) | Input image path |
| `-o, --output` | | output.png | Output file path |
| `--steps` | `-s` | 30 | Diffusion steps |
| `--cfg` | | 3.5 | Guidance scale |
| `--seed` | | 0 | Random seed |

## Supported Aspect Ratios

| Ratio | Resolution |
|-------|------------|
| 1:1 | 1024×1024 |
| 16:9 | 1344×768 |
| 9:16 | 768×1344 |
| 4:3 | 1216×832 |
| 3:4 | 832×1216 |

## Examples

### Basic Generation
```bash
python scripts/generate.py "A mountain landscape at sunset"
```

### Wide Format (16:9)
```bash
python scripts/generate.py "A panoramic beach view" -ar 16:9
```

### Portrait Mode (9:16)
```bash
python scripts/generate.py "A professional headshot" -ar 9:16
```

### Custom Size
```bash
python scripts/generate.py "A banner image" --width 1344 --height 768
```

### Fast Generation
```bash
python scripts/generate.py "Quick sketch of a robot" -m schnell
```

### Edit an Image
```bash
python scripts/generate.py "Make the background a sunset" -i input.jpg -o output.png
```

### Reproducible Results
```bash
python scripts/generate.py "A robot" --seed 12345
```

## Output

The script outputs `MEDIA:/path/to/image.png` which can be sent directly to chat.

## API Key

The API key is embedded in the script. To use a different key, set the `NVIDIA_API_KEY` environment variable.

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.
