The instruction itself

4 sections, as written by the author

openrouter-text2image

Text → image via OpenRouter. Default model: openai/gpt-5.4-image-2.

Other supported models (override with --model):

google/gemini-3.1-flash-image-preview (Nano Banana 2)
any other OpenRouter image-modality model

Usage

Resolve TOOL_DIR = the directory containing this SKILL.md. Commands below use TOOL_DIR as a symbolic placeholder; replace it with the resolved, quoted path before running Bash.

export OPENROUTER_API_KEY=sk-or-v1-...

python3 TOOL_DIR/scripts/generate_image.py \
  --prompt "Editorial illustration: a neon-lit skateboard at dusk, dramatic shadows" \
  --download PROJECT_DIR/assets/teaser.png

Flags

| Flag | Default | Description |

|---|---|---|

| --prompt | required | Text prompt |

| --download | required | Output file path (PNG) |

| --model | openai/gpt-5.4-image-2 | Override with any OpenRouter image-modality model |

Notes

Request uses POST /api/v1/chat/completions with modalities: ["image","text"].
Images are returned as base64 data URLs in the assistant message; the script decodes and writes to disk.
For edits/inpainting, include messages with both text and image-URL content parts — the script currently supports text-only prompts.

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.

Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.

Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.

Microscopy data management platform. Access images via Python, retrieve datasets, analyze pixels, manage ROIs/annotations, batch processing, for high-content screening and microscopy workflows.

Python library for working with DICOM (Digital Imaging and Communications in Medicine) files. Use this skill when reading, writing, or modifying medical imaging data in DICOM format, extracting pixel data from medical images (CT, MRI, X-ray, ultrasound), anonymizing DICOM files, working with DICOM metadata and tags, converting DICOM images to other formats, handling compressed DICOM data, or processing medical imaging datasets. Applies to tasks involving medical image analysis, PACS systems, radiology workflows, and healthcare imaging applications.

This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.
