Cursor published an engineering account of how it prepared its own codebase so that cloud-based coding agents could build, run and test changes. The company reports that these agents now author more than half of the code changes merged into its main repository, up from about a tenth in December. The write-up describes internal tooling, including a single command-line entry point for developers and agents and an automated checker that repairs broken environments, rather than a new product release.
What changed
In December, cloud agents wrote about one in ten of the code changes merged into Cursor's own codebase.
What it unlocks
A written account of the specific environment work — a unified command-line tool, security controls around secrets, and a self-repairing setup — that let coding agents run and test code without a human checking out the branch.
