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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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+.

Turns ComfyUI workflows into MCP tools with no code, covering generation and conversion across text, image, speech and video; works with local ComfyUI or RunningHub in the cloud. Start the server with uvx pixelle and configure an LLM first.

Atlassian's official plugin: connects the cloud Atlassian MCP to search and create Jira issues, read and write Confluence pages and manage sprints, with skills that turn meeting notes into tasks and generate status reports. Needs an Atlassian Cloud account with OAuth or an API token.

Atlassian's official hosted remote MCP: access Jira, Confluence, JSM, Bitbucket, Loom and more with OAuth or an API token. Works with Atlassian Cloud sites only.

Works with Outlook mail and calendar, OneDrive, Excel, OneNote, To Do and more through Microsoft Graph, plus Teams and SharePoint in organization mode. Community-maintained, with a read-only mode.

Microsoft's official Microsoft 365 MCP: query your email, meetings, OneDrive and SharePoint files, Teams messages and colleagues in plain language, e.g. tomorrow's meetings or someone's budget emails. Needs a Microsoft 365 Copilot license, tenant admin consent and Node.js 18+; public preview.

ComfyUI's official CLI: install and launch ComfyUI in one step, manage custom nodes and model downloads, and run image and video workflows, with --json output on every command for agents. Can also submit jobs to paid Comfy Cloud.

Command-line client for Linear: list, search, create and update issues and projects, create Git branches from issues and open PRs, with a bundled skill for agents. Needs a Linear account and an API key to log in; community-built, not from Linear.

Graph database MCP server from Neo4j Labs: reads the graph schema and runs read and write Cypher queries, with read-only mode, query timeouts and response token limits. Needs a Neo4j instance with the APOC plugin enabled.
