DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 Nothing is uploaded unless you explicitly select **Yes**. Organizations with [zero data retention](/docs/en/zero-data-retention), or where product feedback is disabled by organization policy, or where `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` is set, never see this follow-up. Your responses to this survey, including session transcripts submitted after the rating prompt, do not impact your data training preferences and cannot be used to train our AI models.
 
-To disable these surveys, set `CLAUDE_CODE_DISABLE_FEEDBACK_SURVEY=1`. The survey is also disabled when `DISABLE_TELEMETRY`, `DO_NOT_TRACK`, or `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` is set. Organizations that block nonessential traffic but capture survey responses through their own [OpenTelemetry collector](/docs/en/monitoring-usage) can opt the survey back in by setting `CLAUDE_CODE_ENABLE_FEEDBACK_SURVEY_FOR_OTEL=1`. The survey then logs ratings to the configured collector only. The transcript-share follow-up and all other Anthropic-bound feedback traffic stay disabled. To control frequency instead of disabling, set [`feedbackSurveyRate`](/docs/en/settings#available-settings) in your settings file to a probability between `0` and `1`.

 When a host platform sets `CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST`, metrics default to on for Google Cloud's Agent Platform, Amazon Bedrock, Microsoft Foundry, and Claude Platform on AWS, and follow the standard `DISABLE_TELEMETRY` opt-out. Error reporting and `/feedback` reports remain off by default on those providers.
