# Generate Flux 2 Klein Images

Creative teams need fast image drafts without losing control over prompt structure and model settings. This skill guides Claude, Codex, and Claude Code to use RunComfy Flux 2 Klein variants for rapid concepts and polished outputs.

## Install

## Capabilities

- Selects the Flux 2 Klein 4B or 9B RunComfy endpoint based on speed or fidelity needs.
- Provides RunComfy CLI command patterns for text-to-image generation.
- Explains prompt structure for subject, scene, style, lighting, camera, and quality details.
- Documents step count, image size, aspect ratio, and reference image limits.
- Describes CLI polling, output download behavior, exit codes, and token handling.

## Use Cases

- Create fast visual concepts: Use the 4B variant to explore product, campaign, or illustration ideas with short feedback cycles.
- Polish selected image prompts: Move a strong concept to the 9B variant with higher step counts for more detail.
- Standardize prompt writing: Apply the documented subject-first prompt grammar across image generation requests.

## Prompt Templates

### Generate a simple concept

```
Use Flux 2 Klein to generate a fast concept image of a modern desk lamp on a clean studio background.
```

### Create a polished product image

```
Use Flux 2 Klein 9B to create a polished product photo of a ceramic mug. Use soft window light, shallow depth of field, and a square output.
```

### Compare fast and final variants

```
Help me iterate with Flux 2 Klein 4B first, then prepare the final Flux 2 Klein 9B command for the best prompt.
```

### Use reference style guidance

```
Use Flux 2 Klein with reference images to keep the same lighting and composition while changing the product color and label text.
```

## Limitations

- Requires the RunComfy CLI, a RunComfy account, and valid authentication.
- Does not generate images locally or provide a self-hosted Flux runtime.
- Depends on RunComfy service availability, model limits, and billing behavior.
- Embedded text and high-resolution output may require other image models.

## Best Practices

- Use the 4B variant for quick exploration and the 9B variant for final polish.
- Keep prompts specific, subject-first, and within the documented length guidance.
- Use trusted reference image URLs and review generated outputs before publishing.

## Anti Patterns

- Do not paste secrets or private data into image prompts or reference URLs.
- Do not request unsupported 4K or extreme aspect ratio outputs from this model.
- Do not mix unrelated visual styles across multiple reference images.

## Security Audit

- Audited at: 2026-07-09T01:35:57.453\+00:00
- Summary: The static findings are almost entirely Markdown examples, documented RunComfy CLI usage, expected RunComfy URLs, or documentation shorthand. No prompt injection, covert command execution, or malicious filesystem behavior was found, but the skill does send prompts and media references to a third-party hosted model service.
