Uber published a blog post detailing how its AI system, AutoClean, automatically cleans up legacy technical debt in production code, such as expired feature flags. Over the past few years, the system has cleared more than 16,000 flags and over a million lines of code.
AutoClean runs continuously across multiple monorepos at Uber. The process consists of three steps: first, an AI agent, combined with the deterministic code transformation tool PolyglotPiranha, rewrites the code; next, it fixes CI failures and repeatedly verifies the changes; finally, after passing static analysis and a review by the multi-agent validation system CodeCourt, the code is handed over to human engineers for a final review. This way, reviewers only need to decide whether to remove a given flag, without having to check for mechanical correctness.
