Claude Code, from Anthropic, is a programming assistant designed to improve development efficiency through natural language interaction. It integrates directly into the development environment without requiring additional servers or complex setup. Leveraging Anthropic's Claude 3.7 model, it understands the context of the codebase and performs tasks such as editing files, fixing bugs, running tests, and handling Git operations. Key advantages of Claude Code include efficient workflow integration, robust contextual understanding, and support for complex programming tasks. Currently in research preview, it will be optimized based on user feedback.
