Sandbox demo
Your First Conversation
Watch the agentic loop in action: a single prompt, a tool call, a result, an answer. This is the heartbeat.
Every Claude Code interaction is a loop. You speak. The agent decides if it needs information from your machine. If yes, it calls a tool — Read, Bash, Grep — and waits for the result. Then it speaks again, and the loop continues until the task is done.
Below is a sandbox replay of a real first conversation. Watch how the agent uses Read to actually look at the file before answering — this is what separates an agent from autocomplete.

The transcript is canned — no real API calls. The point is to internalize the loop: user → plan → tool → result → answer.
