claude-api skill: the new auto permission policy

A September 10 change in Anthropics skills repository updated the claude-api skill for Managed Agents. Alongside always_allow and always_ask, it documents a third permission policy called auto, with three outcomes: the call runs, it is denied as high-risk while the session keeps running, or it pauses for approval when the evaluation is indeterminate. Client guides now gate on evaluated_permission equalling ask, rather than on the configured policy name alone.

Attach a live session from the terminal

The same commit documents ant beta:sessions connect in the CLI guide. The command attaches your terminal to an existing session, follows the transcript live, and supports allow or deny prompts when a tool call is waiting. A --web flag serves a local session viewer. The deny path uses deny_message as the real field name.

Keep installation boring with the skills CLI

The Vercel labs skills repository describes a CLI for the open agent skills ecosystem, with support listed for OpenCode, Claude Code, Codex and Cursor. Use it when you want a repeatable way to list and update installed skills instead of copying files by hand.

Turn page checks into saved evidence

Anthropics webapp-testing skill is documented as a toolkit for interacting with and testing local web applications, including frontend checks that can leave screenshots and browser logs. Treat that as documentation of intent, not as a claim we ran every recipe ourselves.

One concrete follow-up

If you use Managed Agents, open the updated claude-api skill notes and confirm whether your client still keys off the configured policy name or off evaluated_permission.
