Browserbase's official skills: drive a local or cloud browser with the browse CLI for web scraping and search, turning site traffic into an OpenAPI spec, adversarial UI testing and competitor research. Cloud features need a Browserbase account.

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

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

NVIDIA's official plugin that finds and installs the right skills from NVIDIA's catalog for your task, spanning CUDA acceleration, NIM inference, NeMo training, RAG blueprints, Omniverse simulation and robotics. Listed in both the Claude and Codex official marketplaces.

NVIDIA's official, verified catalog of hundreds of skills covering CUDA-X libraries, NeMo training, NIM and Dynamo inference, RAG blueprints, Jetson, Omniverse and robotics simulation. The install adds only nvidia-skill-finder, which recommends other skills and installs them once you confirm.

One server connecting PostgreSQL, MySQL, MariaDB, SQL Server, Oracle and SQLite, exposing just two tools by default to save context, with read-only mode and SSH tunneling. From Bytebase.

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.

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 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 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.

Community plugin marketplace bundling hundreds of subagents, slash commands, hooks and skills by category, installable individually or all at once, with the buildwithclaude.com site for browsing community plugins and MCP servers.

Grafana's official MCP: search and edit dashboards, query Prometheus, Loki and other data sources, and view alerts, incidents and OnCall schedules to help with troubleshooting. Needs a Grafana URL and a service account token.

Query Google Analytics 4 in natural language: read account and property info and run standard, funnel and realtime reports. Official from Google Analytics (experimental); requires Google Cloud Application Default Credentials.

Plugin marketplace for investment research: six plugin groups covering yfinance market data, earnings previews and recaps, DCF valuation, option payoff charts, ETF premiums, read-only news from X, Discord and other social sources, and TradingView data. Research only, not investment advice.

PostgreSQL MCP server with database health checks, index tuning, EXPLAIN plan analysis and hypothetical index simulation, plus safe read-only SQL execution in restricted mode.

Kubernetes' official CLI for inspecting and managing Pods, Deployments, Services and other cluster resources, reading logs, executing commands in containers and applying YAML manifests. Requires a working kubeconfig for cluster access.

About 40 research skills from Google DeepMind: search arXiv, PubMed and OpenAlex, query UniProt, PDB, ClinVar, ChEMBL and more, run AlphaGenome variant analysis and render structures in PyMOL. Requires uv; AlphaGenome needs an API key, and keys raise limits for OpenAlex, ClinVar and others.

Framework for writing data transformation models in SQL or Python, with a Terraform-like plan/apply flow, virtual data environments, unit tests and table diffs, and transpilation across 10+ SQL dialects. A Linux Foundation project and an alternative to dbt.

Lets agents write and run Playwright scripts on the fly for browser testing and automation, auto-detecting local dev servers, with screenshots, responsive checks, login flows and link checking. After installing, run npm run setup in the skill directory.

Lets agents write and run Playwright scripts on the fly for browser automation: page tests, UX checks and multi-step flows, opening a visible browser by default and auto-detecting local dev servers. After installing the plugin, run npm run setup in the skill directory.
