+We're thrilled to introduce agentic planning on GitHub for CodeRabbit chat. This enhancement lets you make more advanced requests that span multiple files. Just add a review comment on any pull request tagging `@coderabbitai` along with your natural language request for a code change, and the chat will develop a plan for complex modifications. This is in addition to existing agentic chat for CodeRabbit.
