What are Claude Code and Claude Cowork, and how do they help?

Question

IT Interview Practice · Accepted Answer

Both are Anthropic's **agentic** tools — they don't just chat, they do multi-step work for you. **Claude Code** focuses on software development; **Claude Cowork** targets broader knowledge work beyond coding.

## Claude Code

Claude Code is Anthropic's agentic coding tool. It works in your **terminal** (with IDE extensions, a desktop app, and web access too), acting as an agent inside your development environment — with your approval for actions. It can:

- **Read and edit files** across your project.
- **Run commands and tests** to build, verify, and iterate.
- **Use git** to inspect history, branch, and commit.
- **Search the codebase** to find where things live before changing them.

```text
You: "Add input validation to the signup endpoint and run the tests."
Claude Code:
  → searches the codebase for the signup handler
  → edits the file to add validation
  → runs the test suite to confirm nothing broke
  (asking for your approval as it acts)
```

So instead of pasting snippets back and forth into a chat window, the agent acts directly in your repo.

## Claude Cowork

Claude Cowork is Anthropic's agentic assistant aimed at **broader knowledge work** beyond coding — multi-step tasks over documents, research, and general office work. The shared idea with Claude Code is the same: an agent that carries out a multi-step task on your behalf, rather than just answering a single question.

## Why it matters

Knowing what these tools are clarifies the shift from chat to agents: Claude Code acts inside your dev environment (files, commands, git, search) so you describe a goal instead of copy-pasting code, while Claude Cowork extends the same agentic, multi-step approach to wider knowledge work. The common thread is an assistant that *does the work*, not one you have to walk through every step.
