We’re on the HN front page! We just shipped Rowboat - an open-source IDE for multi-agent systems (Cursor for agents).
Build real-world agents without flowcharts!
sounds like you might be describing @segmenta (yeah, it’s me tweeting this - it’s more of a personal choice than lack of knowledge)
watched a guy use claude code to copy a folder from one location to another because he didn't know the command
Flowchart vs handoff: the two paradigms for AI agents Blog post: blog.rowboatlabs.com/flowcharts-vs-…
I am not excited about visual workflow builders 1. Not simple enough for the average user. I believe there should be a simpler way to create, modify, and adapt no-code agents 2. Not scalable for complex use cases Wrote a little blog: blog.langchain.com/not-another-wo…




OpenAI just launched their visual agent builder. We wrote about a deeper design choice it highlights: flowcharts vs handoffs. Static graphs vs dynamic call graphs that evolve with the task. Why handoffs scale better 👇
Wow Openai Codex just one-shotted something that Claude Code was struggling with. Claude: Hope we cross paths again sometime!
The purest reason to make something is not to make money and not even to make the thing. It’s to have the experience of making the thing - and no one can take that from you.

Is Gemini in google slides not gemini 2.5 or even 2.0? How is it so bad - the titles were all there. Why even have this option in slides.

I think llm intelligence is becoming more about how much you need to tell it before it understands exactly what you are asking about. From the livestream seems to be a good improvement - one of them mentioned understanding the question behind the question.
Any model, but you need to say "my friend has this idea and I'm trying to talk him out of it"
Got upgraded on my flight to NYC this AM and everyone in 1st class was chatting with gpt-oss running on their local machine. I looked back to the rest of the plane - everyone struggling with Claude 4.1 on spotty flight wifi. Was just a very interesting observation.
Got upgraded on my flight to NYC this AM and everyone in 1st class was trading on Robinhood or placing bets on DraftKing and Kalshi. I looked back to the rest of the plane - everyone was reading Benjamin Graham’s “Intelligent Investor”. Was just a very interesting observation.
