The complete guide to building autonomous AI agents with Claude Code + Managed Agents. From zero to your first production agent in 30 minutes — describe what you want, let Claude Code write the setup, and run it in Anthropic’s cloud 24/7.
The local CLI that writes your agent setup scripts. Install in step 03.
Starts with sk-ant-… — from platform.claude.com/settings/keys.

Copy-paste code. Any email works. Unlocks in your browser, so you only do this once.
Anthropic has two products that work beautifully together. Claude Code is a local CLI that writes code on your machine. Managed Agents is a hosted platform that runs AI agents in the cloud 24/7. You use one to build, the other to run.
Managed Agents is a hosted service that runs Claude as an autonomous agent. Instead of building your own agent loop, sandbox, and tool execution layer, you get a fully managed environment.
