Key Insight : Individual developers using AI agents see 2-5x gains, but scaling across teams requires infrastructure. mabl’s engineering team built a four-layer system: per-repo operating manuals, validation pipelines, shared agent/human tools, and layered governance where AI blocks bad code and humans always approve merges. This architecture resulted in impressive gains in efficiency and is offered as a reference for teams looking to operationalizing agentic development at production scale.
