the brief

Agents took center stage: Cloudflare rolled out a full agentic stack from WebMCP to an agent-first browser, while OpenAI pushed an Agent Plugins standard and refreshed ChatGPT’s defaults. Hardware and platform moves (AMD–Taalas, Stripe–OpenRouter) hint at consolidation, and DeepMind’s WeatherNext arrives with state-of-the-art cyclone forecasting. Mind your pipelines—GitHub Actions had a rough patch—and patch Datasette if you mix public and private tables.
