Claude Code is Anthropic’s terminal-native AI coding agent. It plans, writes, tests, and ships code with minimal supervision — running directly in your shell rather than nested inside an IDE extension. We cover it more than any other tool on this site, because it’s the implementation that comes closest to making spec-driven development work in practice.
