The advent of "atmosphere programming" is revolutionizing the workflow of developers. While this approach significantly boosts development efficiency, it also introduces novel challenges. Anthropic has unveiled its AI-powered code review tool, Code Review, on the Claude Code platform. Currently, it is available for research preview exclusively to users of the Claude Team and Enterprise editions. This innovative tool is designed to identify vulnerabilities before code is committed to the repository, with a particular strength in rectifying logical errors. It systematically elucidates its reasoning process and employs a color-coded system to indicate the severity of identified issues. Leveraging a multi-agent parallel working mode, it offers fundamental security analysis. Moreover, engineering leaders have the flexibility to customize additional check items according to their specific needs. Pricing for the tool is based on token usage, with the average cost per review falling between $15 and $25. The introduction of Code Review is a response to the market's pressing need for efficient code reviews, and it is anticipated to facilitate companies in achieving faster and more secure development processes.
