A new reminder can tell Claude that the user only sees a few lines of Bash output, so it must repeat what matters in its reply
A new system-reminder type, bash_output_audience_note, is appended to Bash-style tool results whose stdout is a string, telling the model that the user's terminal shows at most a few lines of that output and anything the user needs must be repeated in the reply.
The note only fires when the env var CLAUDE_CODE_BASH_OUTPUT_AUDIENCE_NOTE is set, or when server-supplied client/model capability data declares support for it; absent both, the helper returns false and no note is added. On this build it is dark by default.
