    EP 20 - Claude Skills, LangChain Agent builder, market updates and MCPCentral.io

    AI Summit and CAT-MIP Initiative Cameron spoke at an AI summit hosted by N-able, a company formerly part of SolarWinds. His talk focused on the infrastructure gaps that Managed Services Providers (MSPs) face when handling AI. Consortium for AI Terminology (CAT-MIP): https://cat-mip.org/N-able (Host Company): https://www.n-able.com/AI Market and Stock News Google's stock is performing exceptionally well, and Gemini reportedly has 600-650 million daily active users. A new deal between Microsoft and OpenAI restructures OpenAI into a public benefit corporation, with Microsoft holding a 27% stake. As part of this, OpenAI pre-committed to purchasing $250 billion in cloud compute from Azure.Gemini User Statistics (Note: Research indicates 35M daily users and 450M monthly users): https://vertu.com/lifestyle/gemini-vs-chatgpt-user-numbers-comparison-features-2025-trends/The MCP Server Deployment Challenge Tom's project involves building an MCP (Model Context Protocol) server for massive.com, the new name for market data provider Polygon. Massive (formerly Polygon): https://massive.com/MCP Central Project Cameron's new project, mcpcentral.io, aims to solve this deployment problem. It builds the necessary infrastructure for the agent layer, making agent deployment and management easy for technical users and MSPs. The platform is designed for multi-tenancy, allowing MSPs to run services for clients without deep DevOps expertise.MCP Central Server Example: https://skywork.ai/skypage/en/ai-engineer-langchain-hub/1981168855956770816LangChain Agent Builder Demo A demo of LangChain's new Agent Builder, currently in private beta, shows how it creates agents from natural language. The tool includes pre-built triggers for services like Gmail, Slack, and Linear. An example email assistant agent successfully analyzed an inbox, categorized emails, and created a draft reply directly in a Gmail drafts folder.LangChain Agent Builder Documentation: https://docs.langchain.com/langsmith/agent-builderClaude Skills Explained and Demoed Anthropic's "Claude Skills" feature has been available for about a month. Skills are defined in skill.md files that provide instructions and can reference scripts, which then run in a secure, sandboxed cloud container. This method saves context and allows for repeatable, complex workflows. A demo of the "MCP builder" skill shows it successfully scaffolding a new, production-ready MCP server for the Massive/Polygon options trading API.Explanation of Claude Skills: https://simonwillison.net/2025/Oct/16/claude-skills/Getting Started with Claude Skills: https://neon.com/blog/getting-started-with-claude-skillsChapters00:00:00 Introduction & Weekly AI News00:01:33 Minimax M2 Model Analysis00:13:15 DGX Hardware Update00:14:19 AI Summit & Managed Services Providers (MSPs)00:16:24 CATMIP: A Terminology Standard for AI in IT00:20:53 Big Tech News: Google, Gemini, and Market Growth00:30:25 Demo: Options Trading MCP Server (Polygon/Massive)00:35:21 The Problem: How to Host and Share MCP Servers00:37:47 MCP Central00:44:20 ChatGPT Connectors & Developer Mode00:49:48 Grok Code Fast Model Update00:50:47 LangChain V1 Updates & LangSmith00:52:13 Demo: LangChain Agent Builder00:57:43 Demo: Email Assistant (Agent Builder)01:12:12 Agent Builder: Multi-Tenancy & Security01:13:43 LangSmith: Annotation, Datasets & Experiments01:18:54 Demo: LangSmith Agent Insights01:23:56 Introduction to Claude Skills01:25:12 Demo: Algorithmic Art Skill01:30:38 Claude Skills GitHub Repo01:33:25 Demo: Canvas Design Skill (Podcast Poster)01:37:41 Claude Plugin Marketplace01:40:00 Claude Skill Creator & MCP Builder01:45:26 Demo: Using the MCP Builder Skill01:50:43 Integrating LangSmith with Claude Code01:55:38 Quick Tip: Remote DGX Access with Cloudflare Tunnels01:56:15 Final Demo: Options Trading MCP Server Build Complete01:58:01 Wrap-up

    EP 18 - Computer Use, Agent Teams, and Spec-Driven Coding

    Key Points Why “computer use” agents matter for real form-filling and CRUD tasks Live look at Gemini 2.5 Computer Use, Browserbase/Playwright, and WebVoyager-style tasks Operator vs Claude/Gemini computer use: accuracy, speed, and safety guardrails (CAPTCHAs, consent, impersonation) Where computer use fits vs MCP tools, local OS access, and classic scraping Veo 3.1 API update: reference images and start/end frames for consistent video Claude Code Plugins & community marketplaces (sub-agents, tools, slash commands) GitHub “Spec Kit” and spec-driven workflows for coding at scale Cerebras inference speed vs quality tradeoffs; why speed sometimes beats depth Local rigs and training: DGX Spark use cases and limits Karpathy’s NanoChat: small-scale train-your-own chat model and cost envelope “Agent Universe” demo: NAICS-led industry mapping → value flows → agent blueprints Architecture questions: vertical vs horizontal agents, data layer, tool connectors (HubSpot, Procore, Google Workspace) A focused walkthrough of today’s agentic stack in practice. The episode tests Gemini 2.5 “computer use” for real browser tasks, compares it with Operator and Claude, and breaks down safety guardrails and why screenshot-loop agents remain slow. It covers where computer use fits alongside MCP and OS tools, then shifts to Veo 3.1’s new API features for reference-guided video. On the coding side, it explores Claude Code Plugins and community marketplaces, plus GitHub’s Spec Kit for spec-driven development on large codebases. The discussion touches Cerebras for ultra-fast inference, DGX Spark for local experiments, and Karpathy’s NanoChat for training compact chat models. It closes with the “Agent Universe” demo: mapping industries via NAICS, generating value-flow diagrams, and turning stages into deployable agent roles, with open questions on architecture, tools, and handoff into real systems.
