ONESHOT_GTM_TELEMETRY=0. Telemetry summarizes invocations with fields such as command, outcome, duration, version and OS. It does not transmit prospect records, prompts, replies or wallet secrets as telemetry.
The GTM repository’s TELEMETRY.md is the authoritative payload and privacy specification. Paid research, model and sending calls still send the data needed to their providers; turning off telemetry does not disable those requested actions.
