Claude Code on Web is struggling with planning today. All "API Error: Stream idle timeout - partial response received" -- plan, ultraplan, etc. Some day I will get Ultraplan to actually work!

@StuartBlitz And they would probably get similar patient outcome results!

If someone had just dumped 100% of their health tech VC fund into Allbirds yesterday, they would have outperformed peer funds

@trq212 I really want to try ultraplan, but I keep having it start from terminal on plans that involve it looking at 2+ local directories as reference. It then only has access to one on web and either realizes it or starts trying to make up what the others do. They're all repos...

New in Claude Code: /ultraplan Claude builds an implementation plan for you on the web. You can read it and edit it, then run the plan on the web or back in your terminal. Available now in preview for all users with CC on the web enabled.

@kevinrose @theswalker I think the “anything” part is under-appreciated by most, but is probably the most fun & exciting thing at the moment. No limits!

@theswalker So fun... you can build anything...

I wish my agents could code faster, I'm cooking something really fun to show you all... killing me to sit on this! soon!

I love Claude, but Opus 4.6 has definitely gotten 1) much less thoughtful 2) much more lazy 3) so much slower -- seems to be getting worse day by day...

@SocketSecurity Can you get them to include it in the bun and uv containers too! Thanks!

"Docker Hardened Images for Node.js, Python, and Rust also include Socket Firewall, which blocks malicious dependencies at install time." Another tool for securing your build pipeline - DHI are free and open source: socket.dev/blog/socket-fi…

@amorriscode I use them a lot, but: 1) agents are inconsistent on where they commit (in main tree vs worktree) and how they combine streams 2) sometimes delete themselves without combining 3) can’t sandbox them because they share project/.git (shared clones work better for this).

I was looking into worktree usage for claude code desktop. A surprising amount of you folks don't use worktress. I wouldn't be able to multi-Claude without them so I'm curious why you don't? How can we make them better or more intuitive for you?

@adamnash @DaffyGiving Congrats @adamnash & team! Amazing milestone!

We launched @DaffyGiving four and a half years ago with a simple question: why couldn't a donor-advised fund be built for everyone? Daffy has now crossed $1 billion in charitable assets. More than $7 per second since we launched. 🎉

@saranormous Next time I’m in!

@schrep I’ve been experimenting with the step past that — I think the PM’ing part can be automated too. I think soon it’ll be: you’re the CEO tossing random ideas, good and bad, over the wall and it making its own decisions on what to build and it just executing with minimal steering.

Working with Claude Code is disorienting. I first thought it was like pair programming with a epic Unix hacker from the 90s, but it is more like PMing that unix hacker who is wicked fast. Promting "this isn't working" followed by log tailing, debugging, and a working deployed change is mind blowing.

@jeffammons There’s a few variants that work pretty well, like if you add humans back to the loop for triage you can more easily keep it on track. On the other hand then you’ve slowed the system down. Lots of opportunities in both directions.

@stuartparmenter I like this idea. I've been working on our teams Claude skills to try to move towards this more hands off coding model whenever possible.

Want the software to just build itself? I've been playing with that idea here: github.com/stuartparmente… Built on Claude Code & Linear, it creates a (fairly) full software development loop from planning to implementation. Room to improve, but is pretty cool to see!

@sm I would invest in this business

God I wish taco trucks drove down streets blasting music and stopping if you flagged them down the same way ice cream trucks do

@StuartBlitz Why even bother with blood? Just use AI to predict the results! What could go wrong?

The problem with lab testing is you need to get in the car, drive to a draw center, and have someone else take tubes of blood from you. It’s 2025 - why can’t you just prick your finger at home and have your iPhone read it instantly?

@LeenaRao @BusinessInsider Congrats Leena!

I’m so excited to be leading @BusinessInsider's formidable team of tech reporters and helping continue to tell the most important stories taking place in big tech, startups, Silicon Valley culture, VC and beyond. x.com/BIPressRoom/st…

@ethanbeard Yeah, I’ve forced myself to try to build without (is painful) but haven’t done the deploy step yet. Soon!

@stuartparmenter Yeah Gemini does a great job with pdfs as well. The ai is the easy api. Soup to nuts idea to deploy without touching code has many more challenges.

I had learned a lot over this time so my prompting was much smarter. In my first tries I gave the AI lots of context about the big picture product to help it understand what it was trying to build. 14/x

@ethanbeard I’ve found Claude to do a decent job of pulling stuff out of PDFs using their document API. Has worked well for invoices, but haven’t tried it on previews…

You can see what I built here: parsepdf.io I'm going to try another project soon and will report back. Comments and questions always welcome! 19/19

@StuartBlitz Not enough AI obviously

Everyone simply wants healthcare to be: * Affordable * Convenient * High quality What’s so hard?

@amanda_robs It is 80 inside already!

Ppl in SF are like “we’re in a heatwave” and it’s literally 70 degrees 😂
