Gifski is a polished macOS application that converts video files into high-quality animated GIFs. The application uses a hybrid architecture: a SwiftUI frontend handles the user interface, video decoding (via AVFoundation), real-time preview compositing (via Metal shaders), and system integration (Share Extension, Shortcuts), while the core GIF encoding is performed by a companion Rust library (gifski-api) exposed through a C API. Key data flows involve decoding video frames, optional cropping/trimming/resizing, temporal denoising and palette quantization in the Rust engine, and finally writing the GIF output. The codebase demonstrates solid engineering with actor-based concurrency, comprehensive unit tests, and reusable UI components. However, it carries technical drift from macOS version workarounds and deprecated Rust API usage, and targets a future macOS version (26+) not yet generally available.
This repository is a curated collection of Claude skills—markdown instructions and supporting scripts that enable Claude (or any MCP-compatible agent) to perform a wide range of tasks, from document manipulation (DOCX, PPTX, PDF, XLSX) and GIF animation to web testing, MCP server building, and automation of hundreds of third-party SaaS services via Composio's Rube MCP. The repo is primarily a skill library with a standardized template for each skill, but it also contains several well-crafted Python libraries (e.g., easing functions, particle systems, OOXML validation frameworks) that are genuinely reusable. The architecture is modular: each skill lives in its own directory with a SKILL.md and optional scripts. The heavy reliance on external services (Composio, Rube MCP) and the massive duplication of templated skill documentation introduce maintenance risks, but the core utility scripts demonstrate solid engineering craftsmanship.
