What Claude Code is
Claude Code is Anthropic’s tool for working with code through natural language. It runs next to a project, understands the codebase, explains complex areas, edits files, handles routine tasks, and works with GitHub.
Unlike ordinary autocomplete, Claude Code behaves like an agent: it reads project context, proposes changes, runs commands, helps with checks, and can be used from the terminal, IDE, or GitHub discussions.
What is inside
The public repository contains the package, installation paths, demo material, plugins, and data-use information. The old npm installation path is deprecated; recommended paths include install scripts, Homebrew, and WinGet.
Starting Claude Code
This shows the common entry: install, move into a project, and run `claude`.
curl -fsSL https://claude.ai/install.sh | bash
cd my-project
claude
Why it is notable
Claude Code became a major entry point into agentic programming because the assistant works inside the project rather than in a detached chat window. It can see files, errors, history, and verification commands.
Limits
An agent needs clear boundaries. Command permissions, diff review, rollback, checks, and data handling matter. Claude Code can speed work up, but architecture and final code quality remain the developer’s responsibility.
