Cognition September 16, 2026 5 min read Today we’re introducing Code Scans : a new way to turn broad engineering goals into concrete improvements across your codebase. Tell Devin what you want to achieve, and it helps you investigate what needs to change, evaluate the findings, and turn them into pull requests. Many engineering tasks start with a specific change. Others start with an outcome: Improve SEO Reduce maintenance overhead Make your application compile faster These goals often stay on the backlog because the first step alone is a substantial project: investigating the codebase to figure out where to start. Additionally, identifying the opportunities is only half the work — someone still has to implement the changes, and many of them. Code Scans helps with both. Powered by Agentic MapReduce , the architecture we built for Devin Security Swarm, Code Scans breaks large investigations into focused batches, distributes them across parallel agents, and synthesizes their findings into one report.…
