What do you need for UCP? There are two levels of UCP readiness. The first is the minimum viable manifest — the bare requirements to pass validation and appear in the UCP directory. The second is the agent-ready setup — what it actually takes for an AI agent to browse, cart, and check out at your store without friction. Think of this as your UCP checklist — the minimum requirements plus the recomm
How I Built a Bitcoin-Only Digital Store (No Stripe, No PayPal) What happened when I deleted my payment processor and embraced financial sovereignty I still remember the day Stripe froze my account. A client disputed a $200 payment and before I could even respond, my entire balance was locked. Three weeks of emails. Two verification requests. And ultimately, a 30-day hold while they "investigate
More rules should mean better output. That's the intuition. I spent weeks building a comprehensive CLAUDE.md — 200 lines covering naming conventions, security rules, error handling, architectural patterns, import ordering, type safety requirements, and more. I was proud of it. I'd thought through every scenario. Then I scored the output. 79.0 / 100. My carefully crafted documentation was actively
"OK, I understand the RPS formula. But is our RPS — actually — high or low compared to our industry?" Right after I published the RPS-definition guide last week, this was the most common question I got back from EC operators. They want to know where they sit, not just how to compute the number. Knowing your RPS is $1.20 means nothing if you don't know whether that's the industry median, the top qu
I run a flower shop in Munich and recently migrated my entire e-commerce setup to Medusa v2. The shop, the One thing that was completely missing: a connection to Lexware Office, which is the most popular accounting software So I built LexBridge - an open-source Medusa v2 plugin that automates the entire invoicing workflow. What it does When a customer places an order, the plugin: Looks up the cust
Have you ever looked at code you wrote six months ago and thought: "Who wrote this monster?"? Relax, it happens to all of us. In software engineering, writing code that a machine understands is the easy part. The real challenge is writing code that other humans (including your future self) can understand, maintain, and scale. This is exactly where Software Design Principles come into play. In this
Part 1 of 5 in The New Engineering Contract — what it means to lead engineers when AI is doing more of the coding. SWE-CI tested 18 AI models across 71 consecutive commits. Most broke something on commit 47 they'd already broken on commit 1. That's not an intelligence problem. That's a learning system that isn't learning. A paper made me uncomfortable this month. Not because of what it found about
