Agentic validation needs different infrastructure

Agents create new problems for typical local and remote testing approaches, as resource consumption, environmental inconsistencies, and CI pipeline startup overhead cause bottlenecks when agents write code. The article introduces Chunk sidecars, fast microVM-based remote environments that offer agent-friendly feedback without inflating infrastructure costs, with early results showing 3x better token efficiency and 10-20x cost savings compared to traditional CI pipelines.
