Google paper: FlowAgent agent fixes CI-failing tests, and speed determines whether developers adopt it
The Google paper introduces FlowAgent, which catches each failing test during the CI stage; the agent repeatedly edits, builds, and reruns the test until it passes, and the verified fix appears in code review along with an explanation of the root cause. Experts judged 67.18% of the fixes correct on 195 real failures, and developers have already applied 28,554 fixes in production. A single run has a median duration of 9.85 minutes, whereas previously the median wait before developers began editing was 27.48 minutes, but many fixes still arrive too late.

Body
Google paper shows that an AI agent can fix failing tests across Google, and speed decides whether developers use the fix.
Tests that fail in CI ( continuous integration) before merge pull developers out of their flow, and existing repair agents mostly work offline after merge.
They built FlowAgent, which catches each test failure and runs an agent that edits, builds, and reruns tests until they pass. Verified fixes appear in code review with a short note on the root cause.
Experts judged 67.18% of its fixes correct on 195 real failures, and developers applied 28,554 fixes in production. Its median run took 9.85 minutes, versus a 27.48-minute median before developers start editing, yet many fixes still arrived too late.
