Claude Code from Anthropic is a powerful agentic coding assistant that integrates directly into your terminal, IDE, or web browser, allowing developers to delegate complex tasks using natural language. Launched as a research project and evolving rapidly through 2025, Claude Code understands entire codebases, executes commands, debugs issues, handles git workflows, and performs multi-step reasoning—all while prioritizing safety and precision.
What is Claude Code?
Claude Code is Anthropic’s terminal-based (and expanding to web/IDE) agentic tool designed to accelerate coding by understanding codebases and executing tasks autonomously. It uses Claude models (e.g., Opus 4.5, Sonnet 4.5) for deep reasoning.
For beginners: Claude Code is like a highly capable pair programmer in your terminal—describe what you need, and it plans, writes, tests, and commits code while explaining steps.
For advanced users: It features context engineering with CLAUDE.md files, subagents for parallel work, skills for specialized tasks, and tools like browser control via Chrome extension. Updates in late 2025 added long-running autonomy and web-based delegation.
