## Purpose

Source: AI-written repository summary; verify against source.

> OpenCodeReview is a hybrid AI-powered code review tool that combines deterministic rule-based pipelines with LLM agents (OpenAI/Anthropic/Claude compatible) to deliver precise line-level review comments.

## Main parts

> CLI & Entry Point: Command-line interface and runtime initialization for the OpenCodeReview tool.
Evidence: AI-written saved map. [bin/ocr.js](https://github.com/alibaba/open-code-review/blob/375f64cd6f67a48a135da83cfcf59c52669a09cb/bin/ocr.js)

> Agent & Orchestration: High-level review orchestration, hybrid pipeline (deterministic + LLM), and agent coordination.

## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> The intended package manager and version are not established by captured evidence.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
