Performs AI-powered code review on Git changes using the `ocr` CLI from alibaba/open-code- review. Use when the user asks to review code, review a pull request, review staged/unstaged changes, review a commit, or compare branches for code quality issues. Produces line-level review comments and can automatically apply fixes when requested. With appropriate review rules, can detect various types of issues including bugs, security vulnerabilities, performance problems, and code quality concerns. Do NOT use when the open-code-review tool is not the target - for general review craft use code-review-excellence.
