Claude Code Daily... Version 3 is live. Just shipped a clean refresh of the daily landing page: tighter flow, better signal extraction, and a soft CTA at the bottom that points builders toward without being pushy. Last week I dropped the previous version straight into the Claude Code subreddit. Result? ~400 visitors, only 5 clickouts. That’s how i test and iterate on Reddit. never blast a direct product link. You share the actual value first. the blog post itself. and let the equal exchange do the work. If someone finds the daily brief useful and wants to go deeper (beyond basic scraping into real intent signals), the path is there naturally. No deception, just reciprocity. builder mindset in action: ship fast, measure honestly, refine in public. does V3 hit cleaner? Drop your thoughts below.

New JD for software engineers: Loop Engineering Boris Cherny, who built Claude Code, said: "I don't prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops." Straight out of latest newsletter, another good summary of how engineers' roles are shifting... The ultimate automation of engineers' job and any operations job using AI loops is a good answer to mangers, investors and shareholders. Especially in the async organization like Babylon Labs, where I have colleagues in 10+ time zones.

Hi HN, The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels have been abused like this. Captchainbox applies the idea of proof-of-work to email. If a sender is willing to do a bit of work to reach you, the message is more likely to be worth your time and the sender more likely to be real. The work is a traditional captcha. You can also set a pay-to-deliver amount if you want more friction. The proceeds of the delivery payment after transaction costs go to the Internet Archive and the EFF. The tool curr

Hey HN, I built an email deliverability SaaS with a RAG system. It's trained on all my knowledge and hundreds of real deliverability use cases from 4+ years experience as an Email Deliverability Specialist on Upwork.

Solo-built an email agent where the AI literally cannot act on its own — the architecture is the pitch Building SmolMail ( https://smolmail.com ) solo for a few months. Two build decisions turned out to be the whole product: Widgets over prose. Every answer renders as a real component (calendar grid, email list, editable forms) and the model only picks the props — so the UI can't hallucinate. The calendar shows what the Calendar API returned, period. No write tool, on purpose. Email
