Lets agents read and write Figma: extract variables, components and styles, create and edit screens, FigJam boards and slides on the canvas, and run accessibility checks and design-system audits. Needs a Figma personal access token, the Figma desktop app, Node.js and the companion plugin.

Simon Willison's website screenshot CLI: batch screenshots from YAML, record demo videos, export PDF and HTML, run JavaScript in pages to extract data, and dump accessibility trees. Built on Playwright; install a browser on first use.

Gives agents on-demand guidance for the modern web platform, covering View Transitions, container queries, Popover, INP optimization, accessibility and more, with browser compatibility data so they avoid outdated code. Maintained by the Google Chrome team; currently in preview.

Runs open image models like FLUX, Qwen Image and Z-Image locally on a Mac: text-to-image, reference-based edits, inpainting and upscaling, all on-device. Needs Apple Silicon and uv; the first run downloads models and is slow. Check each model's license before commercial use.

Apify's official skill collection: picks from 130+ curated Actors to scrape public data from social networks, maps, e-commerce sites and more, and can also build, package and deploy Actors. Needs an Apify account; a free tier is available.

Four tools for real-time web search, page content extraction, site mapping and full-site crawling, available as a remote server or run locally. Maintained by Tavily; needs an API key or OAuth sign-in, and a free account is available.

Supabase's official CLI: runs the full backend stack locally (Postgres, Auth, Storage, Edge Functions), manages database migrations, generates types and deploys functions. The local stack requires Docker.

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.

Reviews mobile and desktop app designs against Apple's Human Interface Guidelines, bundled as 123 pages from developer.apple.com, citing the exact guideline through five review lenses, and flags generic, templated choices. Works on screenshots, mockups or code for SwiftUI, Flutter or Electron.

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.

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.

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.

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.

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 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 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.

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.

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.

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.

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.

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.

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.
