Alibaba turns large-scale code review into a precision-first CLI
Alibaba has open-sourced the AI code-review assistant it says served tens of thousands of developers and flagged millions of defects internally. Open Code Review combines an agent with deterministic checks, line-level comments, codebase search, and full-file scans, then targets fewer false alarms: its benchmark covers 200 real pull requests, 10 languages, and 1,505 engineer-annotated issues. The trade-off is explicit: higher precision and lower token use, but lower recall than general-purpose coding agents.
