We Measured Grep on Real Codebases. Here's What Actually Breaks.

We measured how coding agents search with grep on Home Assistant and Saleor: about 150 model runs and 13 million tokens. Grep finds the files, then buries them in noise, and it can't follow inheritance or code that never says the name. A bigger model doesn't fix it.

Grep, Then Jev: A $0.04 Judge for Picking the Right Code Files

Grep finds 87% of the files a question needs, then buries them in noise. We put TypeSafe's Jev classifier behind grep on 5,075 candidate files from Saleor, Kubernetes, Istio, Argo CD, cert-manager and etcd. It found more of the right files than Opus 5.5 at about 1% of the cost.

Why "Context Graph" Has Become the Most Misunderstood Term in AI Engineering

A technical deep-dive into LLM context management, the computational limits of context windows, and why every AI tool's 'context graph' solution might just be clever marketing around semantic search and RAG.
