Anthropic reported that it redesigned its developer source-control system by replacing Git with an in-house platform called Scion due to increased code-change volume tied to Claude-driven work. It introduced new review and migration workflows, and completed a monorepo migration over roughly five months while moving build, CI, and source-control operations toward an always-online, horizontally scalable client-server setup.
