Concrete experience from building a Go framework with AI as the primary developer (not just a helper): the properties that make Go good for agents are exactly what you'd expect — one formatter, one build system, static typing, and a strong convention around package structure.

The part that surprised me: the bottleneck wasn't AI capability. It was that the tooling wasn't designed for AI as the builder. Once I locked architectural decisions upfront and enforced a single way to do everything, the AI stopped hallucinating boilerplate and started making genuinely good decisions.

Zero ambiguity in the codebase = zero drift in AI-generated code.
