The instruction itself

6 sections, as written by the author

openrouter-text2video

Text → video via OpenRouter. Default model: bytedance/seedance-2.0.

Uses the async video-generation endpoint: submit job → poll → download.

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_video.py \
  --prompt "A slow dolly push through a retro-futuristic arcade, neon signs reflecting in a puddle" \
  --duration 5 \
  --aspect-ratio 16:9 \
  --resolution 720p \
  --download PROJECT_DIR/assets/hero.mp4

Flags

| Flag | Default | Description |

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

| --prompt | required | Text prompt |

| --download | required | Output MP4 path |

| --model | bytedance/seedance-2.0 | Any OpenRouter video model |

| --duration | 5 | Seconds |

| --aspect-ratio | 16:9 | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, 9:21 |

| --resolution | 720p | Model-dependent (e.g. 480p, 720p, 1080p) |

| --generate-audio | off | Generate audio with video (if model supports) |

| --poll-interval | 5 | Seconds between polls |

| --max-wait | 600 | Max total wait time |

Flow

POST /api/v1/videos → returns {id, polling_url, status: "pending"}
GET /api/v1/videos/{id} every 5s until status == "completed"
GET /api/v1/videos/{id}/content → raw MP4 bytes

Pricing

Seedance 2.0: ~$7/M tokens with (height × width × duration × 24) / 1024 token formula. A 5-second 720p 16:9 clip ≈ 145k tokens ≈ $1.

Notes

Supports text-to-video, image-to-video (first/last frame control via frame_images), and reference-to-video.
This script only wires text-to-video. Extend the body to add frame_images or input_references for advanced modes.

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.
