Why grovestack
The essays here are expanded versions of Grant's LinkedIn series — longer, more concrete, built for people who want to do the work, not just nod at the thesis. The thesis is that AI-native engineering isn't about better prompts; it's about the systems — specifications, validation, orchestration, context — that make AI output reliable on a Tuesday morning.
