Two Git ignore files nobody told me about

This article highlights a low-cost but high-value Git hygiene practice: using repository-local .git/info/exclude and machine-level global ignore files to keep personal notes, agent artifacts, and OS/editor clutter out of working trees without exposing them to the whole team. For CIOs and technology leaders, the strategic implication is that small developer-experience improvements can reduce friction, improve focus, and lower the risk of accidental leakage of non-shared files, while reinforcing better standards for local versus committed configuration across IT teams. It also shows how AI tooling is increasingly surfacing operational knowledge that can improve productivity, but organizations should ensure teams understand the boundaries between local convenience and shared repository policy.
