1. Isolated execution and propose-validate-iterate workflows for running coding agents at scale

Craig Risi on InfoQ. Coverage of Dropbox’s internal Nova platform describes an architecture for operating AI coding agents at scale built around isolated, cloud-based execution where agents work through a propose, validate, iterate loop. The design integrates agents directly with existing engineering infrastructure, including Bazel builds, monorepo pipelines, and CI systems, so proposed changes are validated against real builds and tests before acceptance, separating code generation from publication. The architectural takeaway is that deterministic workflows, observability, guardrails, and contextual knowledge sources beyond source code are what make agent execution reliable rather than the agent model alone.
