Today's concept: what Claude Code is and new features in Claude code
Claude Code isn't a chatbot that tells you what to code - it's a pair programmer that actually does the coding, sees what breaks, and fixes it in real time.
Claude Code is an IDE where Claude can edit files, run tests, search your codebase, and iterate on its own work. Think of it like the difference between a navigation app that gives you directions vs. one that can actually drive the car - it's not just outputting suggestions, it's making changes, observing the results (syntax errors, test failures, runtime behavior), and course-correcting. You run it three ways: CLI, VS Code extension, or web app at claude.ai/code.
When you build an agent in production, it faces the same wall: it can observe task failures, but if the goal itself was wrong, iteration spins in place. That's why real agentic systems need a human checkpoint at decision boundaries, not just automated retry loops. Claude Code lets you see exactly where that boundary is before you deploy an agent that'll waste tokens on the wrong problem.
Quick check before you scroll: Why is it more useful that Claude Code can run your tests and see the output, rather than just generate code you copy-paste into your editor?

The answer
Because Claude can verify its own work - when a test fails or syntax breaks, it sees that immediately and debugs it. That's the closed loop: change → observe → correct. A chatbot generating code leaves the verification (and debug loop) entirely to you.
