Google's FlowAgent proposes and validates fixes for failing pre-submit tests in code review
Overview
Google has proposed FlowAgent, an agentic program repair system that runs a ReAct-style loop to generate and validate fixes for pre-submit test failures and displays them inside Google's code review tools.
Two abstention filters, applied before and after execution, decide whether a fix is worth showing.
In a manual review of 195 real failures, 67.18% of FlowAgent's fixes were correct, according to the report. After the Google-wide launch, the system suggested fixes on 295,508 changes, with developers previewing 65,069 of them and applying 28,554. These figures come from the report's description of the deployment and have not been independently verified.
