Unclear Which gate(s) control this and what the billing notice specifically concerns are not established by the evidence.
When Claude Code runs in a mode without an interactive display, such as with --output-format stream-json --verbose (a mode that streams structured JSON events instead of a normal terminal view, with --verbose showing full turn-by-turn output), a billing notice that would normally appear as a dialog is now delivered differently. It's emitted as a warning event in the stream-json output, or written directly to standard error (stderr) otherwise, before normal output begins.
This lets automated or scripted sessions that can't show a dialog still receive the same billing notice, in a form that fits the output format they're already consuming.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Anthropic's documentation has since written up --verbose, on CLI reference.
