Uses hooks to enforce test-driven development in Claude Code: blocks implementation without a failing test, prevents code beyond what tests require, and can use lint results to push refactoring. Needs Node.js 22+. Still maintained, but the author suggests its successor Probity for new projects.

WordPress's official skill collection: block development, block themes, plugin architecture, REST API, Interactivity API, WP-CLI, performance profiling and Playground, so agents write code to modern WordPress standards and avoid common security pitfalls.

TypeUI's design fundamentals skill: general UI and interaction principles covering visual hierarchy, spacing, typography, 30 laws of interaction and WCAG accessibility. Needs Node.js to install; the TypeUI design-system library needs its hosted MCP and sign-in.

MiniMax's official CLI, built for agents: chat with MiniMax models from the terminal and generate images, video and speech, plus speech transcription, image understanding and web search. Works with the international platform. Requires a MiniMax Token Plan subscription.

A CLI and Python library by Simon Willison: imports JSON and CSV straight into SQLite with automatic table creation, runs in-memory SQL queries over files, and supports full-text search and table transformations.

Turns Figma designs into production code in your project, using the design screenshot as the visual target and reusing existing components, design tokens and Code Connect mappings first. Maintained by Figma; needs the Figma MCP server (free plans get only 6 calls a month).

Figma's official skill that teaches agents to run Plugin API scripts via use_figma, creating and editing nodes, components, variables and auto layout directly on the canvas. Load it before any use_figma call. Needs a Figma account and the remote MCP server.

Figma's official skill collection: implement designs as code, map components with Code Connect, generate design-system libraries from code, and build screens and FigJam diagrams on the canvas. Needs the Figma MCP server; canvas writes are in beta and currently free.

Figma's official plugin: connects the remote Figma MCP server and bundles skills for design-to-code, Code Connect, and generating designs and libraries, letting agents read design context and write to the canvas. Needs a Figma account; Starter plans and View/Collab seats get 6 calls a month.

Builds editable Figma designs on the canvas from screens, modals or sidebars in your code, or from a text description, reusing components and variables from the file's published design system first. Maintained by Figma; needs the remote Figma MCP server and the figma-use skill.

Unofficial Intercom CLI built with Printing Press, covering the full REST API: sync conversations and contacts for offline search, bulk-tag conversations about one incident, see customer overviews and SLA reports, and pull or push help articles. US, EU and AU regions; needs an access token.

Breaks reference UIs you like (screenshots, images or URLs) into a structured design DNA JSON covering design tokens, overall style and visual effects, then builds new pages from your content in that style. Installing needs Node.js; no API key required.

Self-hostable long-term memory for agents, offering MCP, a REST API and a web dashboard: semantic search, knowledge graph and automatic memory consolidation. Embeddings are computed locally; choose SQLite, Cloudflare or Milvus as the backend.

Command-line tool for inspecting, compressing and optimizing glTF/GLB 3D models, with Draco and Meshopt mesh compression, texture resizing and WebP/KTX2 compression; a single optimize command handles it all.

SDK and CLI for reading, editing and optimizing glTF 2.0 3D models: one optimize command does it all, or run Draco and Meshopt geometry compression, texture resizing and WebP or KTX2 compression separately. Suits game and web 3D assets.

AI localization: deploy the server to your own Vercel account (Postgres and AI Gateway included; enable deployment protection afterwards), then run npx languine@selfhosted translate to translate locale files with LLMs. A GitHub Action can open PRs. Needs a Vercel account and Node.js.

Fetches US, Hong Kong and China A-share stock data with zero runtime dependencies: real-time quotes, daily, weekly and monthly candles and search as JSON, falling back across Tencent, Sina and Eastmoney sources. Also runs as an MCP server. Unofficial public APIs, no stability guarantee.

Netlify's official CLI: deploy sites, run projects locally with Netlify Dev, manage environment variables, Functions and Blobs, and call the Netlify API directly. Needs Node.js 22.13+ and a Netlify account.

A three-stage workflow for math modeling contests like MCM/ICM and CUMCM: analysis, solving and plotting in Python or MATLAB, and a Word (optionally LaTeX) paper, with stage-check subagents and OpenAlex plus AnySearch literature search. Generated papers are for reference only.

MathWorks' official server that lets agents start your local MATLAB, write and run scripts and unit tests, and check code style and potential errors, for computing, simulation and data analysis. Needs a licensed MATLAB R2021a+ and the downloaded server binary.

Recommends daily papers from arXiv and Semantic Scholar by research interest, reads them and writes illustrated Obsidian notes and a paper graph; can also search venues like CVPR and NeurIPS. Needs Python 3, Obsidian, a vault path and an interests config; the web app needs an Anthropic API key.

From Harvard Medical School's Zitnik Lab: one MCP connecting 1,000+ scientific tools and databases for drugs and targets, genes and proteins, clinical trials, FDA data and PubMed, for biomedical and drug research. Runs with uv; some sources need API keys; medical conclusions need expert review.

Built by Callstack from The Ultimate Guide to React Native Optimization: diagnoses dropped frames, slow startup, bundle size, memory leaks, unnecessary re-renders and janky animations, across both JS and native iOS/Android.

Econometrician Pedro Sant'Anna's academic Claude Code setup (fork the repo to use it): Beamer/Quarto lecture slides, paper review and mock refereeing, R/Python analysis and replication packages, with specialist subagents and quality gates. Needs Git and Python; slides need XeLaTeX and Quarto.
