Claude Code is a coding tool from Anthropic that works on your codebase from the terminal and other surfaces. This post replaces an earlier version and summarizes only what Anthropic’s documentation states. It is a description, not a review.
What it is
Anthropic’s overview describes Claude Code as an agentic coding tool that reads your codebase, edits files, runs commands and integrates with development tools. It is available in the terminal, in IDE extensions for VS Code and JetBrains, in a desktop app and on the web.
Installing it
The documentation lists a native installer as the recommended route on macOS, Linux and Windows, plus Homebrew and WinGet. After installing, you open a project folder and run claude; it prompts you to log in the first time. Native installs update in the background, while Homebrew and WinGet installs need manual upgrades.
What the docs say you can do with it
- Write tests, fix lint errors, resolve merge conflicts and update dependencies.
- Build features and fix bugs from a plain-language description.
- Create commits and pull requests through git, and run in CI with GitHub Actions or GitLab CI/CD.
- Connect to other tools through the Model Context Protocol.
- Follow project instructions stored in a
CLAUDE.mdfile, and use skills and hooks for repeatable workflows. - Run several agents in parallel for different parts of a task.
Accounts
Most surfaces need a Claude subscription or an Anthropic Console account, and the terminal CLI, VS Code and JetBrains also support some third-party providers. See Anthropic’s pricing page for current plans.
Using it carefully
An AI tool that edits files and runs commands can make mistakes. Review its changes before committing, keep work under version control, and read the permission prompts. Anthropic’s best practices page covers workflow guidance.
