open-code-review

Open Code Review is an open-source AI code review tool incubated within Alibaba Group. It reads Git diffs by configuring model endpoints and sends changed files to an LLM agent with tool-use capabilities, generating structured, line-level review comments. The agent can read full file contents, search the codebase, examine other modified files for context, and produce in-depth reviews. In addition to diff-based reviews, `ocr scan` can review entire files, useful for auditing unfamiliar codebases or directories with no meaningful changes. The tool has been validated at scale within Alibaba, serving tens of thousands of developers and identifying millions of code defects.
