To quote from my keynote at Vercel's internal offsite: Software is free as in puppies. It will pee in your bedroom and eat your furniture. The weight of every line of code is real. We will need to maintain it. We will need to port it. It goes into the context window. And somebody in this room will get paged at 2am because it did something unexpected

Using useworkflow.dev durable workflows for agentic operations @yournextstore. It's great, queues simplified. But I think the most remarkable usecase are Hooks & Webhooks. Create a hook that waits for user's interaction (i.e. click a link) and then continue. So simple.

Using tasks schedule from Claude Code on the web to run cron-like operations with agents. My experience so far? 🫶 It's particularly useful paired with custom skills – so that the same operations can be easily run locally or on schedule in the cloud.

Multi-currency stores are coming to @yournextstore. Start with automatic currency conversion rates, then fine-tune spreads manually if you want. Keep those prices round.

@claudeai I've been waiting a week for a support response – what’s the usual timeframe? 😅

@AnthropicAI it’s about a billing issue. I want to give you my money but I can’t.

I had the opportunity to talk about @yournextstore approach to AI with @vercel and @claudeai Code during the @callstackio AI SDK event. Learn how we're connecting Vercel Sandbox, Claude Code and Next.js using WebSockets and… git. youtube.com/watch?v=Yz0E8-VM…

We heavily rely on Server Actions (Next.js) in @yournextstore Thanks to @stripe's new Checkout Session APIs added last year – built specifically for server-side updates – we migrated from raw-dogging Payment Intents to Checkout Sessions. And it’s been bliss. Opened so many doors.

Tried vinext and I couldn't even get to the first screen: ❌ env variables not loaded ❌ next/fonts not working ❌ I'm using "unsupported" React version ❌ missing workflows ❌ `Class extends value undefined is not a constructor or null` everywhere 100% hype, 0% usability

Is it possible to load new skills without restarting Claude Code? @claudeai We're using Claude Agent SDK in a sandbox for @yournextstore and restarting the whole process is a bit of a pain. @bcherny

My 30-chars password is weak, according to @Apple. But `Jacket1!` apparently is "strong".
