Claude Managed Agents get auto mode and a session viewer

Anthropic has added two features to Claude Managed Agents: a session viewer in the ant CLI, reached with ant beta:sessions connect, and an auto mode in which Claude reviews each tool call before it runs. The company announced both through its ClaudeDevs account on X.

At a glance

• The session viewer runs in two forms: ant beta:sessions connect attaches the terminal to a session already in flight, and the --web flag opens the same view as a web UI served from localhost.
• Under auto, Claude weighs each tool call against the intent expressed in user.message events and then takes one of three routes: run the call, deny it, or hand the decision back for input.
• Managed Agents already had a Console session viewer rebuilt for multi-agent sessions in August, and the CLI addition puts the same kind of session inspection in the terminal alongside a localhost web view.

Long-running agent sessions are hard to supervise once they leave the foreground, and the two updates address opposite ends of that problem: visibility into what a session is doing, and a gate on what it is allowed to do. Auto mode in particular reads as a shift from fixed allow-and-deny lists toward a model judging each call in context, which trades predictability for coverage of cases no rule anticipated.

The command sits under the CLI's beta namespace, so it is reachable as ant beta:sessions connect. It attaches the current terminal to a session that is already running rather than starting a new one, and adding --web opens a web UI served from localhost instead, which keeps the interface on the machine running the command.

Auto mode changes how tool calls are approved in a Managed Agents session. Anthropic says Claude reviews each call against the intent expressed in the session's user.message events, then either runs the call, denies it, or stops and asks the user for input. The judgement is made per call rather than once for the whole session.

Managed Agents already had a session viewer in the Console, which was rebuilt in August for multi-agent sessions. The CLI additions move that inspection into the terminal, where a session can be attached directly or handed to a browser on localhost.

Where version 1.30.0 leaves things

The ant CLI release notes on platform.claude.com currently run up to version 1.30.0, dated September 3, and carry no description of either the session viewer or auto mode. No version number has been attached to either feature, and no timeline has been given for beta:sessions moving out of the beta namespace.
