Cloud sessions are Claude Code sessions that run on Anthropic's servers instead of on your own computer. When your organization's policy does not allow them, Claude Code shows a message beginning "Cloud sessions aren't available with". That message has changed.
If the session is signed in with one of these, the message now names it and says Claude Code checked the policy for the organization that key or token belongs to:
ANTHROPIC_API_KEY, an environment variable holding an API keyANTHROPIC_AUTH_TOKEN, an environment variable holding an access token- a key produced by
apiKeyHelper, a setting that runs your own command to supply the key
When Claude Code is connected through a provider other than Anthropic itself, it shows a different message.
If a key or token from another organization is set on your machine, the policy that was checked may not be your own organization's. The message now tells you which credential was used, so you can see why cloud sessions are blocked and which setting to change.
