When Unsloth published its guide on how to train your own decision model , I immediately thought of the North Sea. In Lunar Laya , I argued that a model should take a state and some text, and return a structured, measurable answer. Here was a way to turn any small LLM into exactly that kind of model, with a probability attached to every answer. So I had to try it on FELN. A quick recap for new readers. FELN (Find Existing Location with N layers) is the little query language behind my RAG , LoRA , Liquid and WebGPU experiments. A question such as “Find gas wells within 5 km of oil pipelines” becomes a plan with three parallel lists: layers , where and relations . The first layer is the one returned; any other layer only filters it through a spatial relation. All those projects generate the whole plan in one go. This time, I wanted to pull out the very first decision and give it to a model that does nothing else: which layers does this question need, and which one is primary? One...

Every time I open my feed these days, somebody has wrapped an API in an MCP server. Weather? MCP. Calendar? MCP. I fully expect my toaster to ship one next week. Don't get me wrong, I like MCP and I use it. But I kept staring at the ArcGIS REST API, with years of well-documented endpoints for search, geocoding, routing, demographics and maps, and asking myself a simple question: does an agent really need another server in front of all of that to be agentic? So I built arcpi to find out. The old way and the new way, in one script arcpi runs on pi , a minimalist agent harness that lives in the terminal. I gave it four small Markdown skills, written from the Esri REST documentation, that tell the model which endpoint to call and with which parameters. And one TypeScript extension that makes the HTTP call as the signed-in user. That's it. No ArcGIS MCP server, no build step, no dependencies. The magic is code mode. Instead of calling one tool, waiting, thinking, and call...
