AISummary of 1 article

Uber's AutoClean has removed more than 16,000 stale feature flags and over 1 million lines of dead code, according to a summary by Meng Shao (@shao__meng) of an Uber Engineering post.

The system splits the work into stages: PolyglotPiranha, a deterministic engine, handles boolean simplification; AI agents make the judgment calls; full monorepo CI checks repairs; and CodeCourt checks four correctness properties before human review.

The figures come from the secondhand summary, not from Uber's post directly.
