Why It Matters
Pioneered the 'terminal-first' approach to AI coding agents, where the AI operates in your shell rather than your editor.
Description
Anthropic's terminal-first agentic coding tool powered by Claude. Rather than working inside an IDE, it operates directly in your terminal — reading files, running commands, and making changes across entire codebases. Known for exceptional deep refactoring and whole-repo reasoning, leveraging Claude's 1 million token context window (roughly 750,000 words).
