Claude Code
Anthropic's agentic coding tool that runs in the terminal and can read, write, and edit files, run commands, and use tools to complete software tasks in your codebase.
Analogy
Like a developer teammate working directly in your project folder, not just chatting about code.
Why it matters
It lets you build and ship automation scripts and integrations with Claude doing the actual file edits and commands.
In practice
Telling Claude Code to add error handling to a script and it edits the files and runs the tests.
