Recent highlights

This week was all about agent tooling: Claude Code shipped background agents and a native PR review flow inside the terminal, while the MCP protocol v1.2 added resource streaming and granular authorization. Together they make production agents noticeably safer and easier to run.

On the research side, the strongest signal is that structured retrieval consistently beats “long context” on real-world tasks — reinforcing the move toward economical architecture, with prompt caching cutting real API bills by 70%+. Alongside, the practical guides keep coming: from building your own code-review agent to an honest take on when fine-tuning actually pays off.
