Andrej Karpathy — AI researcher, former Director of AI @ Tesla, founding team @ OpenAI — flagged a new supply chain attack targeting npm axios, the most popular HTTP client library with 300M weekly downloads. He scanned his system and found a use imported from googleworkspace/cli. While the installed version resolved to an unaffected 1.13.5, the project dependency is not pinned, meaning anyone doing this earlier today would have been compromised. He argues that package management defaults (pip, npm, etc.) need to change so that a single infection doesn’t spread through users at random via unpinned dependencies.

Swyx — builder @dxtipshq, @cognition, @temporalio — pointed out that “sign in with ChatGPT” already exists via Codex app server, and accused people of not reading the docs despite Sam Altman asking for it at the town hall.

Josh Woodward — VP @ Google Labs, Gemini App, Google AI Studio — announced a new featured notebook in NotebookLM: “The Science Of Ben Franklin,” created in collaboration with The Royal Society (the oldest scientific academy in continuous existence). It features Franklin’s original papers, letters, and contemporary sources.

Guillermo Rauch — CEO @ Vercel — shared that since Opus 4.5 came out, agents now do most of their coding at Vercel. Given the inherent flaws and over-confidence of LLMs, they sent clear guidance to teams: “Vibing and mission-critical infrastructure don’t go together.” They’re sharing early internal guidance on “agenting responsibly,” prioritizing security, durability, and availability.

Aaron Levie — CEO @ Box — argued that there’s a huge opportunity for entrepreneurial talent to go in and reimagine workflows for a world of agents. He emphasized that automating work with agents requires real work: setting up unstructured data, learning workflows, creating skills for agents, connecting systems, and redesigning processes themselves. Unlike coding gains that come more easily, knowledge work requires this upfront investment. He predicts huge growth of roles for people who specialize in this.

Ryo Lu — Design @ Cursor AI, early @ NotionHQ, @ Stripe — shared a reflective thread on “when software had a soul.” He described the moment around 2005 when using a Mac felt alive — with bouncing docks, genie effects, exposé. He argued that somewhere along the way, we traded all that for growth: A/B tests flattened the edges, design systems standardized personality out, everything got faster and smoother but less interesting. Now with AI agents, you can generate an entire product in an afternoon — and the internet is filling up with software that functions but means nothing. His thesis: the best things are made by people who “couldn’t help themselves” — someone who lost sleep over an icon. AI doesn’t make that irrelevant; it makes it rarer and more valuable. The path forward isn’t making more slop faster, but giving people with real vision the tools to make what they imagined but couldn’t build alone.

He also posted a brief Japanese note that Cursor is coming soon, and a reminder: “we are doing all this for the humans, not the other way around.”

Garry Tan — President & CEO @ Y Combinator — shared several posts: “Many such cases” in response to something, was “Tempted” about something, and announced he shipped an improvement to the /review skill on GStack tonight.

Zara Zhang — Builder, Harvard ‘17 — demonstrated that Lark CLI (Feishu’s command line tool) can now access AND operate all your chats, calendars, meetings, docs, and sheets. She built a skill on top that extracts to-dos from meetings and actually EXECUTES them — calling it “insane.” Also noted that codebase-to-course now has 2.6k stars on GitHub, optimized to be more token efficient & reliable, originally for vibe coders to learn CS but also great for developer onboarding.

Nikunj Kothari — Partner @ fpvventures — shared a reflective take: when he met Ivan Zhao 12 years ago, he remember thinking he’d never met anyone who cares so much about building tools that bring people together. He pushed back on the narrative that AI will replace humans — arguing we should be preaching MORE about the “abundant era” where AI takes care of all the frivolous work we hate doing, and we get to build and think together all the dreams we stored away waiting for a better day.

Dan Shipper — CEO @ Every — criticized a company’s communication around a data privacy issue as a “mealy mouthed way to say ‘we pushed a bug that served your users private data to other users of your app’” — calling it “really, really bad.”

Claude — AI assistant built by Anthropic — announced that Auto mode for Claude Code is now available on the Enterprise plan and for API users. To try it out, update your install and run claude --enable-auto-mode.
