😶‍🌫️Jamstack!? Agents & browsers. CSS, Rust and Tanstack DB. AI eats clicks, Google swings updates

We’re living in the probabilistic era—and AI agents are rewriting the rulebook for devs and marketers.

An era has ended for our Nebojsa Radakovic. For five years, he has been running a LinkedIn newsletter, Jamstack Shortcuts (yes, that is possible), covering topics related to Jamstack and other frontend and web development (one of the reasons we have him now). Anyways...what do we have this time?

From security pitfalls and prompt-injection vulnerabilities to what makes GPT hallucinate and how to measure LLM performance meaningfully—AI links are for anyone wanting to understand how AI agents really work, and what’s at stake when they go off the rails.

Whether you’re wrestling with MCP’s broader implications or just trying to offload that heavy computation, dev articles cut through the noise and show you what’s changing (and how to adapt). Rust, CSS, and Tanstack DB guides included.

Finally, in marketing, new studies have lifted the curtain on which brands and domains are getting cited most across GPT-5, Google AI Mode/Overviews, Perplexity, Copilot, and more. At the same time, guides like AI Search Manual are laying out the early playbook for “Generative Engine Optimization (GEO)” — how to show up in AI answers, not just in search rankings.

Happy reading.
