Battle Drones: A Vibe-Coded RTS and the Agent Loop That Made It Fun
Simon Willison's Battle Drones went through 12 major iterations and 321 commits, mostly written by coding agents. The most useful parts for builders are how the agent tested its own game and why a deterministic simulation was needed.

The 'Obituary for Programming' and What Coding Agents Take Away
Jeremy Scheff's essay, amplified by Simon Willison, names a loss that benchmarks don't measure: the puzzle-solving craft that made programming a good job. For builders shipping with agents, it points at where human judgment still has to live.

Bluesky's Attie Moves From Custom Feeds to Shareable Mini Apps
Bluesky's AI tool Attie started as a way to build your own feeds. It now lets people describe small social apps, such as games, polls and dashboards, and share each one as its own website. It is another sign that vibecoding is moving from developer tooling to ordinary users.

ChatGPT's Intelligent UI: Why Chat Answers Are Becoming Interfaces
