17* Claude Managed Agents permission policies now include `auto`: the server evaluates each agent or MCP tool call and runs it, denies it, or pauses for your approval. `agent.tool_use` and `agent.mcp_tool_use` events report how each call was evaluated in an `evaluation` field alongside `evaluated_permission`. See [Let the server evaluate each call with `auto`](https://platform.claude.com/docs/en/managed-agents/permission-policies#let-the-server-evaluate-each-call-with-auto).
18* The `ant` CLI adds `ant beta:sessions connect`, which attaches your terminal to a Claude Managed Agents session. You can follow the session live, send messages, and allow or deny tool calls that are waiting for approval. Pass `--web` to serve the Claude Console's session viewer locally and open the session there instead. See [Connect to a Managed Agents session from your terminal](https://platform.claude.com/docs/en/cli-sdks-libraries/cli/sessions-connect).

1722* Version 1.30.0 of the `ant` CLI adds `ant apply`, which creates and updates agents, environments, skills, memory stores, and deployments from files in your repository. Describe each resource in a file, run `ant apply`, and approve the plan it prints. Commit the `claude-lock.json` lockfile it writes so that later runs, on your machine or in CI, update the same resources instead of creating new ones. See [Manage resources as code with ant apply](https://platform.claude.com/docs/en/cli-sdks-libraries/cli/apply).
