TV apps are one of the hardest places to be productive as a developer. More than 5 platforms. Different input models. Endless focus bugs. With the rise of the AI driven development I decided to evolve my daily task of writing (and fixing) TV boilerplate and teach an AI agent to do it instead. A real coding harness with tools, skills, and a sense of how TV apps actually work. In this talk I'll share what I learned building that harness on top of the Claude Agent SDK and Strands SDK: how to structure tools, when to use one SDK versus the other, how to keep the agent honest with SOPs and evals, and how to bridge it into Android Studio, Gradle, and platform CLIs. Expect live demos, real failure modes, and a takeaway repo you can use as a starting point for your own domain-specific agent, TV or not.
