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.

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.

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.

Adds voice conversations to Claude Code and other agents: speak, and it detects silence, transcribes, and reads replies aloud. Runs offline with local Whisper and Kokoro, or uses OpenAI's speech APIs; needs a microphone and speakers.

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.

Gives agents controlled access to MySQL: list databases and tables, inspect schemas and sample data, and run SQL, with multi-database mode, SSL and SSH tunnels. Configure your own database user, ideally with least privilege.

Free two-way Figma MCP that needs no paid Dev Mode seat: turns designs into code that fits your existing project, or builds pages and components on the canvas from a description, with data staying on your machine. Needs Node.js 20.19+, the Figma desktop app and the companion plugin.

Generates book covers, movie posters, article covers and social images from one sentence, picking colors and composition from 30+ poster masters' styles to suit the subject. Rendering directly needs Python and a PipeLLM image API key; or just generate prompts for another image tool.

Web search and page reading for agents through a self-hosted or trusted SearXNG metasearch instance, with no paid search API key. Requires a SearXNG instance with JSON output enabled.

Pulls new papers from Hugging Face Daily Papers and arXiv, scores them by research area into a recommendation page, and writes deep-read Obsidian notes for key ones; can also batch-read Zotero collections. Needs Python 3, Obsidian and poppler; copy the whole skills folder per the README.

MathWorks' official toolkit for reading, building, modifying and testing Simulink models via the MATLAB MCP server, with skills for control design, Simscape, code generation and compliance checks. Needs licensed MATLAB R2023a+ and Simulink; run the official installer in MATLAB first.

LangChain's official skill collection: framework selection, quickstarts, middleware, persistence, human-in-the-loop approval, RAG and eval design across LangChain, LangGraph and Deep Agents, in Python and TypeScript. Also installable as a Claude Code plugin. Still in early development.

Plugin marketplace from obra, author of Superpowers: includes the superpowers engineering workflow, episodic-memory for searching past sessions, superpowers-chrome for browser control, elements-of-style writing guidance and more.

Connects agents to live Jupyter notebooks: read, write, insert and execute cells and read multimodal outputs like charts, for interactive data analysis. Bring your own JupyterLab or JupyterHub; open source, maintained by Datalayer.

MathWorks' official toolkit: set up the MCP server via the MATLAB installer so agents can run code, run tests and do static checks; domain skill sets for signal processing, controls, statistics and machine learning install as Claude Code plugins. Needs MATLAB R2021a+.

From startup idea to validation plan: market research, customer interviews, business model and financial projections, plus competitor battlecards, April Dunford positioning and investor pitches of several lengths. Spawns research subagents (token-heavy); projections are only estimates.

Microsoft's official local MCP server for creating and editing Power BI semantic model tables, measures and relationships in natural language, running and validating DAX queries, and bulk renaming and translation. Connects to Power BI Desktop, Fabric or PBIP files; in public preview.

The standard machine translation scorer: computes BLEU, chrF and TER with significance tests and downloads public test sets such as WMT, to compare engines or prompts. Needs Python 3.9+ and reference translations; automatic metrics are a rough screen, so final copy still needs human review.

Experimental open-source generative media MCP servers from Google Cloud: Nano Banana images, Veo video, Gemini TTS and Chirp voices, Lyria music, and AVTool for compositing. Each registers separately; needs a billing-enabled Google Cloud project and gcloud login; AVTool needs FFmpeg.

Pre-submission review for CS conference papers (CVPR, ACL, NeurIPS and more): polish, translate or condense on request, or let AI reviewers raise issues and a jury rule on them. Only wording fixes are drafted, with your approval; missing experiments go back to you, never invented. Needs Node.js.

Lets agents manage Google Calendar across multiple accounts and calendars: search, create, update and delete events, find free time, detect conflicts, and import events from images, PDFs or links. Needs your own Google Cloud OAuth credentials.
