Claude Code

Claude Code is a command-line agent from Anthropic that lives in your terminal, reads your whole repo, edits files, runs tests, and commits. It is best for real multi-file work and refactors where you want the model to plan and execute, not just autocomplete. The tradeoff is that it runs in the terminal rather than a full editor UI, so it suits people comfortable with a CLI more than point-and-click builders.
