Adapts an explanation to its audience, from a 5-year-old to a high schooler, college student, parent or executive, adjusting vocabulary, analogies, tone and depth. Useful for teachers, parents and explaining expert topics to laypeople. No account or extra software needed.

Higgsfield's official skills: generate images, video and voiceover from a single prompt for product shots, e-commerce hero images, YouTube thumbnails, brand guidelines and narrated explainers. Requires the Higgsfield CLI and a signed-in account; generations use account credits.

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.

Community-maintained Slack MCP: reads channel, DM and thread history, searches messages and fetches unread messages; write actions like posting are off by default and must be enabled explicitly. Works with user OAuth or bot tokens over stdio, SSE or HTTP.

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.

Generates product shots, marketing posters and illustrations, removes or swaps backgrounds, upscales and makes videos, with 1,400+ prompt templates and parallel variations. Cloud use needs a MeiGen account and paid credits; the npm version can use OpenAI-compatible APIs or local ComfyUI.

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.

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.

From product photos and a brief, plans a full e-commerce visual set (main images, Amazon/Shopify detail pages, social promos, livestream scenes) with briefs and image prompts, using 25 scene templates and a consistent style. Renders with an OpenAI-compatible image API key; needs Python 3.10+.

Figma's official CLI that links Figma design-system components to real components in your code, so Dev Mode and the Figma MCP show production snippets instead of generated examples. Needs Node.js 18+, a Figma Organization or Enterprise plan, a full Design or Dev Mode seat and an access token.

Reads and writes Obsidian vaults from the terminal: search, view, create, edit, move and delete notes, and manage frontmatter and daily notes, without Obsidian running. Good for agents maintaining a personal knowledge base. Formerly Obsidian CLI.

User research skill: drafts research plans, screeners and interview guides, and turns transcripts into reports with coding tables, personas and priorities, no account needed. AI-moderated interviews, surveys and recruiting real or synthetic participants need a Cookiy AI account, billed per use.

Uses the Qdrant vector database as a semantic memory layer for agents: store information and retrieve it by meaning, connecting to a remote instance or a local path, with FastEmbed generating embeddings by default. Maintained by Qdrant.

Motion design skill built on the ideas of design engineers Emil Kowalski, Jakub Krehel and Jhey Tompkins: builds animated UI components for your project type, or audits existing animations in an HTML report with looping demos. Use in a coding agent on a local frontend project.

People-management skill pack for managers and HR with 7 skills: performance reviews, performance improvement plans (PIPs), 360-degree feedback surveys, interview scorecards, team health checks, team offsites and a 90-day plan for new managers. Text-only; no account or API key.

Connects LLMs to ROS and ROS 2 robots: publish and subscribe to topics, call services and actions, set parameters, and read sensor and robot state, without changing robot code. The robot side needs rosbridge running.

Hiring lessons from 21 Lenny's Podcast and Newsletter guests on recruiting product managers and engineers: defining the role, sourcing through networks, assessing potential and closing offers, with frameworks and question lists. Methodology-focused, for recruiters and hiring managers.

Collects hiring advice from dozens of Lenny's Podcast and Newsletter guests to help you design realistic work samples or paid trials, shared rubrics and solid reference checks, instead of hiring on interview polish and resumes. Geared to product and tech teams; prompt-only, no account.

76 product skills distilled from Lenny's Podcast and Newsletter, covering product strategy, prioritization, user interviews, PRD writing, OKRs, launches and growth, hiring and team management. Each includes frameworks, checklists and templates, with verified quotes. Docs only, no account.

Helps managers and HR partners prepare tough performance feedback: frameworks like GAIN and Radical Candor, turning judgments into observable facts, role-playing the conversation, and planning follow-up. Distilled from Lenny's Podcast and Newsletter guests; prompt-only, no account needed.

Searches 200,000+ icons from 150+ libraries such as Lucide and Material Design, suggests icons by use case, and returns SVG or React, Vue and other component code, or writes them into your icon file. Handy for AI-built pages and UI prototypes. No account or API key; needs Node.js.

Opens HTML, Markdown or localhost pages in the browser via npx human-review so you can edit text directly and leave anchored comments, then sends every edit and comment back to the agent in one batch to apply to the source.

Community CLI for Feishu (Lark) focused on two-way conversion between Markdown and Feishu docs; also works with wikis, sheets, Bitable, messages, calendar, tasks and meeting notes, and ships 9 agent skills. Setup creates an app via QR scan; search and mail need extra user authorization.
