Not every message you send to Claude Code needs the most capable model. A quick question about a Git command runs on the same model as a refactor across three services, unless you remember to switch models first. Jev, a new model from TypeSafe AI, can make that decision for you in a few hundred milliseconds and for a fraction of a cent. So I built jev-router, an open source router that asks Jev which Claude model each of your messages needs, and sends it there. What Jev is After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?I’ve spent the last 2…
In May I told you to trim the root instruction file until it fits on one screen. I also said anything that needs a hard guarantee belongs in a hook. In June I argued that the model that wrote the code shouldn’t be the one grading it. Several papers published this summer tested related questions. Most of the findings support that advice, while the research on subagent costs calls for more caution. Below are ten tips for working with any coding agent. Each one is checked against what the research measured, which is sometimes narrower than the abstract suggests. Instructions kept only in chat…

I got a lot of feedback on my post AI-assisted genealogy, some good, some not so good. In any case, I felt the subject was interesting to a lot of people. Meanwhile, I continue working on my tree, and I have deepened my understanding of the subject. In this post, I want to share again. Trust, but verify Let’s address the not-so-good feedback first. The gist of it was: AI can hallucinate. It’s true in theory: when you ask a question, it provides any answer.
My son recently came to me to brag about using AI to find our ancestors. While the results were correct, I didn’t learn anything new, as it stopped at my grandparents. I was never very interested in my genealogy, but I decided to see if AI would be a good tool for this. TL;DR: Yes, it is, and even more than that. In a little less than one month, I managed to gather more than 600 individuals and get back 12 generations in some branches.
Before working for 2 years on the Apache APISIX API gateway, I was mainly oblivious to API gateways. It’s only by working with them that I understood their value. Decoupling the client and the server unlocks a lot of options: moving authentication to the API Gateway, securing APIs, deduplicating API requests, etc. In this post, I want to describe how the same pattern applies to AI. AI gateways AI gateways work in a similar way.
Google just published a set of Android skills a collection of expert, AI-optimised instructions covering the most common and painful Android development workflows. (Upgrading to AGP 9, migrating XML layouts to Compose, wiring up Navigation 3.) AI automated step-by-step procedures grounded in official Android best practices. The GitHub repo defaults to wiring them into Gemini […] The post Android Skills: Expert Instructions for Your AI Agent first appeared on Blundell.
