What Structured Data Your Product Page Needs in 2026

What Structured Data Your Product Page Needs in 2026 The rules for product schema used to be pretty simple. Add Product, Offer, and maybe AggregateRating, and you were done. Google was happy. Your rich snippets looked nice. You moved on. Those days are over. AI shopping agents are reading structured data differently than Google's crawler does, and they need a much fuller set of fields ...

Bridging 'I Want to Build' and 'I Want to Publish Safely' for Non-Engineers — Sandbox MCP

Hi, I'm Ryan, CTO at airCloset. In my previous posts, I've introduced our internal MCP servers: an MCP server for natural-language search across all our databases, the full picture of our 17 internal MCP servers, and a custom Graph RAG that lets AI answer "Did that initiative actually work?". This time I'm covering something a bit different: Sandbox MCP — a platform that lets non-engineer employ...

Part 1: One Spec To Rule Them All

One Spec to rule them all, one Spec to find them, one Spec to bring them all, and in the darkness bind them. This is the first post in a series about spec-driven development. Not which tool to use or how to get started, but what I learned after living with a spec long enough to hit the problems that nobody writes about yet. I do not have all the answers and I am not trying to be a guru. I am sh...

Asked a colleague in code review to extract magic numbers and got told “devs should know”

Had a slightly frustrating code review interaction and I’m curious how others would handle it and if I’m overthinking this or not? The colleague submitted a PR with logic like: > if abs(lat) > 180 { ... } and similar checks using 90 and 180 regarding coordinates. I asked what those numbers meant and asked if he could extract them into a constants enum so the intent is clearer: > if abs(la...

On Foundation Models in Minecraft

I remember being 14, sitting in a dark room illuminated only by the glow of a monitor and the blue hum of a nuclear reactor. Back then, "advanced" Minecraft was a matter of physical logic— IndustrialCraft 2 cables snaking through walls, Logistics Pipes chattering as they sorted ores, and Railcraft tracks carving paths across frozen winter chunks to feed an insatiable appetite for power. It was a w...
