FEATURE

Auto mode switches to server-side classifier, saving extra evaluation overhead

When letting Claude handle tasks in auto mode, you no longer need to pay extra overhead for the underlying evaluations.

For Claude API and Enterprise users, as well as Bedrock, Vertex, Foundry, and major gateways, auto mode now defaults to enabling the server-side classifier. This mechanism does not charge for classifier overhead, and the system actively warns if it falls back to a billed process. Simply run the /status command to check whether the current session is running on the server in the newly added Auto mode server row. To opt out on Bedrock, Vertex, Foundry, or gateways, simply set the environment variable to CLAUDE_CODE_AUTO_MODE_SERVER=0.

Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (`CLAUDE_CODE_AUTO_MODE_SERVER=0` opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback. See https://code.claude.com/docs/en/auto-mode-classifier-billing
Added an `Auto mode server` row to `/status` showing whether this session's auto mode classifier runs on the server
