Mixedbread's official semantic grep: search code, text, PDFs and images in natural language, and hook it into Claude Code, Codex and other coding agents in one step to cut token use. Requires a Mixedbread sign-in, and files are synced to its cloud index.

Generates 26+ chart types with AntV, including line, bar, Sankey, word cloud, mind map and pivot table, returning image links. Officially maintained by Ant Group's AntV team; uses a public rendering service by default and can be self-hosted.

Multithreaded lossless PNG optimizer that shrinks screenshots, slices and icons in bulk without quality loss and strips unneeded metadata, handy for design handoff or compressing images before a site launch. Install with Homebrew on macOS.

Create, read and modify xlsx workbooks without Microsoft Excel installed: formulas, formatting and conditional formatting, charts, pivot tables and tables. Runs locally over stdio or as a remote HTTP service.

High-fidelity SVG rendering library and CLI that exports SVG icons and illustrations to PNG at chosen sizes, good for batch asset export. No system dependencies, with pixel-identical output across platforms. No SVG animation support; install with cargo or grab a macOS build from Releases.

Open-source, self-hostable localization platform with a built-in MCP server: agents search keys, create and edit translations, manage languages and run machine translation. Works with Tolgee Cloud or your own instance; create a project API key or personal access token in settings.

Three.js texture reference with code: loading and configuring texture maps, UV mapping, cubemaps and HDR environment maps, texture settings and optimization.

Three.js geometry reference with code: parameters for built-in shapes like boxes, spheres, cylinders and tori, building custom meshes from vertices with BufferGeometry, and instanced rendering for large numbers of objects.

Three.js lighting reference with code: ambient, hemisphere, directional, point, spot and area lights with their cost and shadow support, shadow setup, image-based environment lighting and lighting performance tips.

Three.js materials reference with code: when to use Basic, Lambert, Phong, Standard, Physical, Toon and other materials, PBR properties such as roughness and metalness, custom ShaderMaterial and material performance.

Three.js post-processing reference with code: chaining passes with EffectComposer, adding bloom, depth of field, color grading, blur and glow, and writing custom screen-space shader passes.

Three.js shader reference with code: writing GLSL vertex and fragment shaders, ShaderMaterial versus RawShaderMaterial, uniforms and animating them, and extending built-in materials for custom visual effects.

Three.js fundamentals with code: setting up the scene, cameras and WebGLRenderer, Object3D hierarchy, coordinate systems and transforms, the render loop and resize handling. A starting point for building a 3D scene on the web.

Three.js asset loading reference with code: loading GLTF models, textures, images and HDR environments, coordinating loaders and progress with LoadingManager, and async loading patterns.

Open-source marketing plugin with 48 skills: SEO and AI search optimization (GEO), GA4 and Search Console analysis, ad diagnostics for Google, Meta, X, LinkedIn, Reddit and TikTok, and WordPress upkeep. Some SEO skills need only a URL; live data requires NotFair OAuth and linked accounts.

Three.js interaction reference with code: raycasting for click detection and object selection, camera controls such as OrbitControls, and mouse and touch input handling for interactive 3D experiences.

Three.js animation reference with code: procedural motion with Clock, the AnimationClip, AnimationMixer and AnimationAction keyframe system, playing GLTF animations, skeletal animation, morph targets and blending multiple animations.

Fast async link checker written in Rust that scans websites and Markdown, HTML and other files for broken links and email addresses, with JSON output, config files and an official GitHub Action, often wired into docs CI.

Expo's official plugin covering Expo Router navigation, native UI, data fetching and SDK upgrades, plus EAS builds, OTA updates and app store submission. Some service-related skills rely on paid EAS.

Expo's official skills: Expo Router navigation, native-feeling UI, animations, native modules and SDK upgrades, plus EAS build and submit, OTA updates and CI workflows. EAS skills use Expo's paid services.

Hugging Face's official hf CLI: search, download and upload models and datasets, manage repos and storage buckets, and run jobs on Hugging Face's cloud. Output adapts automatically for agents, and hf skills add installs companion skills. Uploads and similar actions need a login.

Knownsec's open-source Python-use agent: describe a task in plain language and it writes and runs Python on your machine, e.g. tidying Excel files, summarizing attendance or screening resumes. Needs Python 3.11+ and a model API key such as DeepSeek; code runs locally, so back up important files.

Extracts any website's logo, colors, fonts, spacing, shadows and motion in one command, exporting W3C design tokens, a Tailwind theme, DESIGN.md or a brand guide PDF, plus WCAG contrast checks. Good for competitor and brand audits. Needs Node.js 18+; run dembrandt install-browser first.

Design engineer Jakub Krehel's UI polish skill covering animation, typography, icons, hover states, optical alignment, concentric radii, shadows and hit areas, with quick and full review modes, so agents get the details right when building or reviewing UI. Works on web code; needs Node.js.
