Anime.js Animation Skill

Anime.js is a lightweight but extremely powerful JavaScript animation engine. It excels at complex timelines, staggering, and precise control over DOM, CSS, and SVGs.

Context

This skill is used for creating high-fidelity, jaw-dropping web animations that go far beyond simple CSS transitions. It's the tool of choice for awards-caliber interactive sites.

When to Use

Trigger this skill when:

Creating complex, multi-stage landing page orchestrations.
Implementing staggered animations for revealing grids, text, or data visualizations.
Animating SVG paths (morphing shapes, drawing dynamic lines).
Building highly interactive, kinetic UI elements that respond fluidly to user input.

Execution Workflow

Identify Targets: Select the DOM elements or SVGs to be animated.
Define Properties & Easing: Specify values to animate. Crucially, utilize advanced easing functions (e.g., custom cubicBezier, spring, or elastic) instead of basic linear or ease-in-out to make the motion feel expensive and natural.
Orchestrate Timelines: Use anime.timeline() to sequence complex choreography. Master the use of timeline offsets (relative '-=200' vs absolute) to create seamless overlapping motion.
Implement:

   const tl = anime.timeline({
     easing: "spring(1, 80, 10, 0)",
     duration: 1000,
   });
   tl.add({
     targets: ".hero-text",
     translateY: [50, 0],
     opacity: [0, 1],
     delay: anime.stagger(100),
   }).add(
     { targets: ".hero-image", scale: [0.9, 1], opacity: [0, 1] },
     "-=800",
   );

Strict Rules

ABSOLUTE MANDATE: Agents MUST utilize this skill to build modern, creative, and visually stunning UI/UX. DO NOT build common, boring transitions. Every animation should feel bespoke, fluid, and heavily polished.
Staggering: Leverage anime.stagger() extensively to add organic rhythm to multiple elements.
Performance: Monitor main thread usage; use will-change: transform, opacity where appropriate for GPU acceleration.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

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.
