A2UI: The Protocol That Lets Agents Speak UI Instead of Writing It
Google's A2UI protocol lets AI agents describe rich, interactive interfaces as safe declarative JSON instead of raw HTML. Here's the architecture, who's running it in production today, and what I think it opens up.
The Data Layer Under Bluesky Is Already Running Its Own Ecosystem
AT Protocol is the identity and data-sync layer under Bluesky, but it's also running production event platforms, blogs, feed builders, and messaging apps that have nothing to do with microblogging. Here's the architecture, the ecosystem, and what's still worth building.

SSR, SSG, and CSR from One Route Table (Platform Is the Framework, Part 2)
Server rendering, static generation, and client rendering, hybrid, per route, from one component set. No Next.js required. Part 2 of the Lit series.

Every metaframework you learn expires. Web components don't. Part 1 of a series on building real apps with Lit and the platform — no React, no Next.js.
Stop Letting Your Agent Write Div Soup: Two Skills for Clean HTML & CSS
I built two open-source agent skills — semantic-html and modern-css — that teach Claude Code, Codex, and OpenCode to write clean, accessible, platform-native web pages instead of div soup and JavaScript hacks. Setup takes two minutes.
