Short answer
Triple Whale Agents are being sunset and replaced by Moby 2 Automations. The exact sunset date will be communicated ahead of time, view our blog page for all the latest.
Context
Until Agents are sunset, both Agents and Moby 2 Automations run in parallel, use this window to migrate each Agent you rely on. Your Agents are listed under Settings → Moby Tools → Agents (Moby 1) during the migration window. Before sunset, copy each Agent's prompt and run configuration into a local document as a backup so you have an offline reference.
