Claude Code

Anthropic's agentic coding tool, run from a terminal or IDE to read, edit, and operate on a real codebase.

Claude Code works directly in a project’s own files and shell rather than a sandboxed chat window — reading code, making edits, running builds and tests, and using tools like to reach further systems, all under the operator’s direction.

It’s the day-to-day AI pair listed under Tools on this page, and this very glossary system — the content collection, the popup engine, and the Playwright coverage for it — was built with it.
