Redesigning Source Control at Anthropic

Anthropic, an artificial intelligence research company, has redesigned its source control system to improve collaboration and efficiency among its engineers. The new system, which replaces the company's previous use of GitHub, uses a self-contained repository that allows multiple teams to work on the same codebase simultaneously without conflicts. This redesign is part of Anthropic's goal to build a more efficient and scalable development workflow. The new system includes features such as a centralized hub for code reviews, automated testing, and a custom-built permission system. Anthropic has also implemented a 'commit graph' that visualizes the relationships between different commits, making it easier for engineers to understand the codebase's history. Additionally, the company has introduced a 'branchless' workflow, where multiple teams can work on the same codebase without the need for branching and merging. This redesign aims to reduce the complexity and overhead associated with traditional source control systems and improve the overall collaboration and productivity of Anthropic's engineering team.
