Claude Code

Claude Code is Anthropic’s tool for software development, built on the Claude models. It lets a programmer delegate coding tasks — writing new features, fixing bugs, refactoring — directly from the command line, with the AI reading and editing files in a project.

It has quickly become a prominent example of “agentic” coding, where the AI does not just suggest snippets but carries out multi-step work across a whole codebase. In one striking case, a designer used Claude Code to port a classic PC game to the iPhone over a weekend.

Claude Code has also featured in business and geopolitical news, such as disputes over which companies and countries are allowed to use it — a sign of how strategically important AI development tools have become.
