DockSmith: Scaling Reliable Coding Environments via an Agentic Docker Builder

arXiv:2602.00592v2 Announce Type: replace Abstract: Reliable Docker-based environment construction is a dominant bottleneck for scaling execution-grounded training and evaluation of software engineering agents. We introduce DockSmith, a specialized agentic Docker builder designed to address this challenge. DockSmith treats environment construction not only as a preprocessing step, but as a core agentic capability that exercises long-horizon tool use, dependency reasoning, and failure recovery, y
