Animation Tool Router Skill for Codex

Use when planning or implementing website motion, scroll choreography, microinteractions, page transitions, text reveals, pinned sections, smooth scrolling, Lottie, Three.js/R3F, WebGL, or animation-heavy premium sites. Chooses the lightest appropriate tool and defines reduced-motion fallbacks.

Animation Tool Router

Use this skill to choose motion tools by purpose, not hype.

Routing

CSS transitions: hover/focus states, small fades, transforms, simple menus.
Motion: React component animation, layout transitions, presence, gestures, small scroll reveals.
GSAP: precise timelines, pinned scroll scenes, split text, SVG paths, complex choreography.
Lenis: smooth scroll feel when the project can support it and anchor/modal behavior is handled.
Lottie: exported vector motion when file weight and accessibility are acceptable.
Three.js/R3F: real 3D product/scene work, not decoration.
No dependency: static content where motion would distract or harm performance.

Motion Requirements

Define:

purpose: reveal, continuity, depth, state, tactility, narrative, or product explanation
trigger: load, hover, focus, click, route, scroll, drag, or viewport
duration/easing
reduced-motion fallback
cleanup/unmount behavior
performance risks

Avoid

animation because the page is otherwise generic
scroll hijacking
motion that hides content
parallax that causes nausea or jank
WebGL scenes that are blank on mobile

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.
