Repository of the day

anthropics/claude-code — Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands. Claude Code is an advanced, terminal-based AI coding assistant developed by Anthropic that deeply integrates with local codebases to accelerate development. It allows developers to execute routine tasks, perform complex refactoring, and safely handle git workflows entirely through natural language commands directly in their CLI. The tool meticulously indexes the local environment to provide highly context-aware suggestions and can autonomously execute multi-step engineering tasks. By living natively in the terminal, it aims to keep developers in their flow state without constantly switching between IDEs, browsers, and chat interfaces.
