Most AI agents are toys for two reasons: they can't run on their own without you hitting go, and they can't safely use a real API key. About a week ago (June 9) Claude fixed both in Managed Agents. So I ran it against a real production checklist and built one live. - What it is. Managed Agents = hiring Anthropic as the landlord for an AI worker. It runs in their locked sandbox, on a schedule, using your tools, and hands back a finished result. Three words: the agent (job + tools), the environment (the safe computer), the session (one run). - What just changed. Deployments = it now runs on a recurring schedule (finest is once a minute), Anthropic fires it for you. Vaults = a tool gets your API key as an env variable, but the agent never sees it โ it's swapped in only to the addresses you allow. - The build. One plain-English prompt made a "morning email brief" agent: read the last 24h of Gmail, sort into needs-reply / FYI / ignore, post to Slack. It wrote its own config, locked networking to just Gmail + Slack, and even created the Slack channel when it didn't exist. - The new part: deployments. Attach the vault, tick "I'm authorized," set the trigger to a schedule (weekdays 9am), done. No server, no scheduler to host โ my inbox is triaged in Slack before coffee. - Honest verdict. Real step toward production, not set-and-forget. Logs/retries/approval gates are there out of the box; you still add your own alerting and testing. It's beta, the key trick only works for straight key-passthrough (AWS-style signed logins don't yet), and the floor is 1 minute. Daily briefs/reports: ready now. Customer- or money-touching jobs: keep a human in the loop. My take: for the simple, on-time jobs that just need to happen without you, this crossed the line from toy to worker. Cost is tiny โ ~$0.08 per session-hour, idle is free, pennies a morning. ๐ Full Managed Agents guide PDF pinned below โ the production checklist, the console tour, the exact build, and the cost breakdown.
