Crisp on the outside, thoughtful on the inside. A keeper.
Summary
Alibaba has open-sourced its internal AI code review tool, Open Code Review, which has been battle-tested at scale serving tens of thousands of developers and identifying millions of code defects. The tool features a hybrid architecture combining deterministic pipelines with an LLM Agent, provides precise line-level comments, and includes built-in fine-tuned rulesets for detecting issues like NPE, thread-safety, XSS, and SQL injection. It reads Git diffs and sends changed files to a configurable LLM via an agent with tool-use capabilities, and is compatible with OpenAI and Anthropic models.
