What is Claude Code?
Claude Code is an agentic AI coding tool developed by Anthropic that enables developers to read codebases, make changes across files, run tests, and deliver committed code. It operates directly within a developer's terminal or integrated development environment (IDE), allowing users to describe a goal in natural language and have Claude Code plan, execute, evaluate, and adjust its actions autonomously. This system streamlines various stages of the software development lifecycle, from rapid code generation to complex refactoring. Recent updates in March 2026 introduced features like a PowerShell tool preview for Windows, enhanced "Computer use" for Pro and Max users enabling screen navigation, and an "Auto mode" to reduce repetitive permission prompts by automatically executing safe actions.
