Devin introduced the Code Scans feature for automating refactoring

Company Devin has implemented the Code Scans tool, designed for automatic detection and correction of issues in the codebase. The system uses Agentic MapReduce architecture to transform high-level tasks, such as compilation time optimization or SEO improvement, into specific code changes.

During internal testing, the feature demonstrated a 96% successful pull request merge rate. The use of the tool allowed saving over 700 hours of engineering time by automating routine analysis and correction stages in repositories.

The mechanism of Code Scans involves decomposing complex goals into subtasks that the agent performs in parallel. This enables the system to independently identify performance bottlenecks and propose ready-made patches, minimizing the need for manual developer intervention at the initial review stage.

The new functionality is focused on scalable projects that require regular code quality audits. Integration of Code Scans into the workflow allows teams to delegate tasks related to maintaining the project's technical state to the agent, while retaining control over the final changes through standard version control mechanisms.
