Anthropic Replaced Git with Scion System for AI Agent Code
Anthropic published a research paper on its proprietary version control system, Scion, which replaced Git for Claude agent code in 5 months by 7 engineers as daily merges grew from 2,500. For the first time, the version control infrastructure designed for AI agents rather than humans is publicly dissected: commits live on the server as write-ahead log records, blame and diff are served via API, and data is distributed across a hierarchy of scion-daemon, scion-cache, and scion-servers caches on top of Spanner.
