What is Open Code Review?
Open Code Review is an AI-powered code review CLI tool. It originated as Alibaba Group's internal official AI code review assistant — over the past two years, it has served tens of thousands of developers and identified millions of code defects. After thorough validation at massive scale, we incubated it into an open source project for the community. Simply configure a model endpoint to get started.
It reads Git diffs, sends changed files to a configurable LLM via an agent with tool-use capabilities, and generates structured review comments with line-level precision. The agent can read full file contents, search the codebase, inspect other changed files for context, and produce deep reviews — not just surface-level diff feedback.

The Problem with General-Purpose Agents
If you've used general-purpose agents like Claude Code with Skills for code review, you've likely encountered these pain points:
Incomplete coverage — On larger changesets, agents tend to "cut corners," selectively reviewing only some files and missing others.
