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.

CodeGraph Cuts AI Agent Tool Calls by 94% with Pre-Indexed Code Knowledge

The open-source CodeGraph project creates a pre-indexed knowledge graph of a codebase, allowing AI coding agents to query it directly. This bypasses the need for repetitive file reads and searches, dramatically reducing the number of costly tool calls required for context gathering. For developers building agents, this translates to faster, cheaper, and more reliable code understanding and generation.
