Eight workflow skills for designers prototyping with AI: requirements interviews, briefs, information architecture, design tokens, task breakdown, UI in a chosen aesthetic and design review, chained by design-flow. Outputs go to .design in the project. For Claude Code, Cursor or Codex.

Chroma's official MCP: lets agents create and manage collections, add documents, and retrieve them with vector search, full-text search and metadata filters. Connects to in-memory or local persistent stores, self-hosted instances or Chroma Cloud.

Fetches captions and transcripts for YouTube videos and Shorts, with language selection and fallback, optional timestamps and sponsor segments filtered by default. No API key for transcripts; the optional visual analysis tool needs a TwelveLabs API key and a direct video URL.

Official Sleek skill: lets agents design mobile app screens in Sleek, manage projects and take preview screenshots, then pull the design HTML and implement it in React Native or SwiftUI. Needs a Sleek account and API key; free accounts get one trial run, ongoing use needs a paid Pro plan.

Community YouTube server built on the YouTube Data API: look up video and channel data, fetch transcripts, browse playlists, and filter creators by subscriber count and upload frequency for influencer scouting. Needs a YouTube Data API key (daily quota) and Node.js.

A macOS say-style text-to-speech CLI that uses ElevenLabs or 60db to speak text aloud or save it as audio (ElevenLabs supports streaming playback), and can list and switch voices. Needs an API key for the chosen service.

Official plugin for Postiz, the open-source social media scheduler: agents use the postiz CLI to upload media, schedule posts to 28+ platforms such as X, LinkedIn, TikTok and Instagram, and check analytics. Needs Node.js, the postiz npm package and a Postiz account (or self-host).

Postiz's official agent CLI: lets AI schedule posts to 28+ platforms such as X, LinkedIn, Instagram, TikTok and YouTube, upload images and video, and check post and account engagement. Ships with skills and a Claude Code plugin. Needs Node.js and a Postiz account (cloud or self-hosted).

Official ClickHouse skills: best practices for schema design, primary keys, JOINs and inserts ranked by impact, advice on real-time architecture decisions, in-process SQL and pandas-compatible analysis with chDB, and local and cloud deployment workflows.

Official ElevenLabs skills: text to speech, speech to text, sound effects and music generation, voice changing, vocal isolation, multilingual dubbing and building voice agents. Needs an ElevenLabs API key.

Uses yt-dlp to pull YouTube subtitles into the agent, so asking it to summarize a video gets you the key points; handy for teachers prepping lessons, researchers and creators. No API key, but needs yt-dlp (Homebrew or WinGet) and Node.js.

Lets agents create, move and scale components in SketchUp, set material colors, read scene info, export models and run Ruby scripts, for quick massing models. No prebuilt package: pack the extension as .rbz, install it in SketchUp and start the server; needs uv.

MCP server for the Lean 4 theorem prover: lets agents read proof goals, diagnostics and definitions and search theorems via LeanSearch and Loogle, helping mathematicians and students with formal proofs. Needs uv and the Lean toolchain; run it from the Lean project root.

Official HeyGen skill: translates existing videos into 175+ languages with dubbing that clones the speaker's voice and re-syncs lips; you can proof subtitles before rendering. Needs a HeyGen account with credits and an API key plus HeyGen CLI, or the HeyGen MCP.

Google's official security MCP servers for Google SecOps (Chronicle), SecOps SOAR, Google Threat Intelligence and Security Command Center: investigate alerts, hunt threats, look up IOCs and review cloud risks. Needs Google Cloud credentials or a VirusTotal API key.

Generates favicons, PWA app icons and Open Graph share images for social platforms from a logo, text or emoji, in every required size with text contrast checks, and can add the matching tags to your web project. Needs Python and Pillow.

Voice skills: TTS with subtitle timing, emotional character voices, translated dubbing, two-host news podcasts, sound effects and songs. Narration and podcasts work with local Kokoro or free voices; emotion, cloning, dubbing, effects and songs need a Noiz API key. Never clone voices to deceive.

68 trading and quant skills focused on crypto and DeFi: market and on-chain data, technical indicators, backtesting, position sizing and risk, prediction markets, and tax tools for cost basis and wash sales. Most need Python and data API keys (often free tiers); get expert review.

Lets agents query Prometheus metrics with PromQL and browse metric metadata and scrape targets to help investigate alerts and performance issues. Supports basic auth, bearer tokens and multi-tenancy; Docker is the recommended way to run it.

Connects Stata to VS Code or Cursor and exposes a local MCP endpoint so Claude Code or Codex can write and run do-files and read regression output, with graphs shown in the editor; for empirical research. Needs a licensed Stata 17+, the extension installed and the editor open.

Automatically aligns subtitles to audio and video with a neural network, and can transcribe subtitles with Whisper or translate them with local models; supports 10+ formats such as SRT, TTML and SCC. Needs Python 3.9-3.12 and FFmpeg; transcription and translation need the llm extra.

Develops an original visual language for a brand, campaign, publication, site or product. Without looking at contemporary design, it builds ten typography-only HTML directions; once you lock one, it turns it into a production system. Not for routine UI fixes or existing design systems.

Official Tavily skills: let agents search the web, extract page content, discover site URLs, crawl in bulk and run cited deep research through the Tavily CLI (tvly). Install the CLI first; search and extract have a limited no-login tier, other features need sign-in or an API key.

Design token CLI (formerly Cobalt UI): reads W3C DTCG tokens for color, type, spacing and more, validates them and generates CSS, Sass, JS/TS, Swift, Tailwind and other code via plugins. Runs in CI so design specs flow into code automatically. Needs a Node.js project.
