What

The SDK lets developers run Claude Code from their own program, called the host, which talks to it through control requests. Three new control requests are added:

  • list_cloud_sessions lists cloud sessions.
  • get_cloud_session fetches one cloud session.
  • get_cloud_session_transcript fetches its transcript.

They are refused, each with its own message, when:

  • started inside a Claude Code session
  • running in a cloud-hosted session ('is not available in a cloud-hosted session')
  • using a provider other than Anthropic's own
  • running an evaluation
  • CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC is set ('Cloud sessions are unavailable while CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC is set.')
  • an organisation policy forbids it
  • you are not signed in with a Claude account (Console sign-ins are refused)

The list of known request names also gains sdk_list_cloud_sessions, sdk_get_cloud_session and sdk_get_cloud_session_transcript, plus names for the Windows sandbox's first start and uninstall.

Why

Programs built on the SDK can now find and read your cloud sessions, and get a clear reason when they are not allowed to.
