Running plain claude can now be automatically routed to a cloud session unless you pass the new --local flag

What

  • A new setting (cloudSessionsByDefault) can cause a plain claude invocation — one with no explicit session, resume, continue, teleport, connect, SSH, worktree, or remote-control flags — to be automatically routed to a cloud session instead of running locally.
  • A new --local flag lets you opt out and force a local session; internally the outcome of this decision is tracked as "none", "declined" (for example because --local was passed), or "applied".
  • This decision (defaultedToCloud) is threaded through the session startup configuration, and reported in telemetry, including a new cloud_session_default event fired on cancel, failure, or success.

Why

This means running Claude Code the normal way could start a cloud session rather than a local one, depending on account or organization configuration. The --local flag is how to guarantee you get a local session.
