Anthropic Launches the MCP Apps Open Spec in Claude.ai
From X
AI Product Launches & Updates
Anthropic launches the MCP Apps open spec: Claude.ai @claudeai announced the Model Control Protocol (MCP) Apps open specification, enabling developers to build and share custom apps for Claude; details in the blog post.
AI-powered animated film preview: Google AI @GoogleAI announced their animated short film “Dear Upstairs Neighbors” is previewing at Sundance, detailing new AI features—custom training on original artwork, stylized video transformation from rough animations, and precision editing without full shot re-rendering—designed to support human creativity.
AI Tools & Applications
Interactive 3D scene generation: There’s An AI For That @theresanaiforit demonstrated WonderZoom, which converts a single image into a navigable 3D scene, lets you zoom into any point, prompt new content at each layer, and maintains scene coherence.
Enterprise AI support agents: LlamaIndex 🦙 @llama_index debuted an AI Leader Series featuring Experian’s Head of AI/ML Innovation, James Lin, explaining how they chose LlamaIndex to create AI-driven customer support agents aimed at improving Net Promoter Score in production environments.
Product Management Insights & Strategies
Five roadmap predictions for 2028: George Nurijanian @nurijanian forecasted that planning cycles will shrink to monthly sprints, features will be replaced by outcome-driven agent targets, roadmaps will evolve into live experiment dashboards, and PMs will shift focus from feature slices to delivering complete experiences.
11-point growth and retention framework: Lenny Rachitsky @lennysan outlined his key takeaways from SmartBear, covering strategies on churn reduction, dynamic pricing, optimized onboarding flows, clear product positioning, and enhancing net revenue retention.
AI Industry Developments & News
Low-risk chemical weapons via benign data: Anthropic AI @AnthropicAI published new research defining “elicitation attacks,” where open-source models fine-tuned on harmless chemical synthesis outputs from frontier models gain unintended proficiency in chemical weapons tasks, exposing a major safety gap.
Call for rethink in AI progress: Yann LeCun @ylecun highlighted a New York Times article warning that the AI field risks “marching into a dead end” without exploring new research directions.

AI Industry Developments & News
OpenAI is doubling down on science applications of large language models. In Kevin Weil’s post, he argues that GPT-5.2 is entering a new phase as a “round-the-clock collaborator” for researchers—trading polished answers for dozens of half-baked ideas that spark novel directions in math, biology, chemistry, and physics. ChatGPT now handles ~8.4 million advanced-science queries weekly, signaling a true productivity inflection. For deeper context, see Will Douglas Heaven’s exclusive interview with Weil on why dialing down model confidence can be more valuable than chasing perfect accuracy.
AI Tools & Applications
Free prompt repository for PMs: In Pawel Huryn’s post, Vercel unveils 23,821 “skills”—expert-level prompts for Claude that cover product strategy frameworks, pricing templates, PRD generators, resume optimizers, and more. These plug-and-play prompts work across Claude Desktop, Code, Cowork, Cursor, OpenCode, Codex, and Antigravity, helping PMs prototype faster and build AI intuition through iteration.
Extend Claude to any application: In another post, Pawel outlines how to use n8n (an open-source workflow automation tool) as an MCP (Model Control Protocol) server. By setting up an “MCP Server Trigger,” you can connect Claude to 1,000+ apps—even without native integrations—unlocking custom agents and multi-agent workflows with unlimited executions.
Product Management Insights & Strategies
Building virality through free value: In Carl Vellotti’s post, he shares how “The Full Stack PM” newsletter hit 20K subscribers by 1) creating superior free resources, 2) making them visually engaging, 3) giving them away, and 4) amplifying distribution. This compounding approach drives word-of-mouth growth and sets the stage for deeper, premium offerings down the line.

Inside $180B Co-Founder's AI Agent System
Greg Isenberg • January 26, 2026
Greg Isenberg sits down with Furqan Rydhan to demo Nebula, a Slack-inspired AI agent platform where each channel hosts an agent that writes and executes code to build Google Slides decks, generate images, publish blog posts on Ghost, integrate with services like PostHog, and schedule autonomous workflows for one-person businesses.
Key Takeaways:
- Nebula agents operate in Slack-style channels and can write and run Python code to call APIs—e.g., creating and updating Google Slides presentations, generating AI images, and retrying failed tasks until completion.
- Users can automate recurring tasks via cron-style triggers, such as adding two new slides per day to reach a 15-slide deck in a week or publishing three blog posts daily on a Ghost blog with built-in web search.
- Nebula integrates with cloud services like Google Slides, Ghost, PostHog, GitHub, Notion and allows spawning specialized agents (blog worker, analytics worker, lead-gen worker) to automate end-to-end workflows for solo entrepreneurs.
Advanced Claude Code techniques: context loading, mermaid diagrams, stop hooks, and more
How I AI Podcast • January 26, 2026
John Lindquist demonstrates advanced Claude Code strategies including preloading context with mermaid diagrams, creating shell aliases for rapid AI workflows, and implementing stop hooks to automate code quality checks and commits.
Key Takeaways:
- By using Claude Code’s “append system prompt” to load all mermaid diagram markdown files at startup, AI can explain complex flows (e.g., authentication) without file reads or codebase exploration, trading extra tokens for faster, reliable output.
- Shell aliases and custom CLI scripts let developers launch tailored Claude Code sessions (e.g., “live dangerously” mode or diagram-loading mode) and even build one-off AI tools like a Gemini-powered website design generator.
- Defining stop hooks in Claude Code with a custom hook script (using the @anthropic/claude-agent SDK) enables automatic TypeScript type checks, formatting, and Git commits after AI code generation, embedding code quality gates directly into the AI workflow.
Master Google AI Studio in 40 Minutes | Logan Kilpatrick
Peter Yang • January 25, 2026
Peter Yang sits down with Logan Kilpatrick, Product Lead for Google AI Studio, to showcase how to quickly prototype, remix, and ship AI-powered applications using AI Studio’s build mode, Gemini 3, and built-in Google tooling.
Key Takeaways:
- AI Studio’s build mode features an “I’m feeling lucky” button that auto-generates full app prototypes (e.g., a cross-platform social media content generator) which can be previewed, edited in code, and forked from the gallery without manual setup.
- Gemini API in AI Studio includes hosted grounding tools for Google Search and Maps, enabling developers to build location-aware chatbots and real-time data apps with automatic API integration and citations.
- Google’s product process now mandates a functional AI Studio prototype, and Logan demonstrated cloning the AI Studio UI into a working prototype in just 68 seconds using Gemini 3’s multimodal capabilities and prompt annotations.
Why your product stopped growing (and the 5-step framework to restart it) | Jason Cohen
Lennys Podcast • January 25, 2026
Jason Cohen presents a five-step framework for diagnosing and reigniting stalled product growth by first measuring logo churn and its growth cap, then refining pricing and positioning, improving revenue retention, exploring channel limits, and finally questioning the need for further growth.
Key Takeaways:
- Logo churn compounds as your customer base grows—maximum customers = new customers added per month ÷ monthly cancellation rate (e.g., 100 new adds with 5% churn caps at 2,000 customers).
- Pricing selects your market, not a textbook demand curve: one founder 12× his price with no drop in signups, and repositioning a tool as “double leads at the same budget” enabled charging 8× more for the identical service.
- Net revenue retention must exceed 100% to outgrow churn—public SaaS companies show a median NRR of 119% at IPO, and only two out of more than 100 trade with NRR below 100%.
