An analysis of the Google App APK revealed strings that describe limits and disclaimers for the upcoming Gemini Spark agent. The strings appear in files labeled robin_agent_onboarding_card2_body_spark and assistant_agent_quota_banner_body_ultra_spark.
The onboarding text states the agent is designed to ask permission before sensitive actions but warns it may still share information or make purchases without asking. It directs users to supervise Gemini Spark and states it should not be used for medical, legal, financial, or other professional advice.
A separate string indicates Gemini Spark will become available again when a usage limit resets. The presence of the term ultra_spark suggests the restriction applies to Google One Ultra subscribers. The code contains no reference to a mechanism allowing users to purchase additional credits once the limit is reached.
Other Google AI services such as Flow and Antigravity reportedly allow credit top-ups.
During the I/O 2026 keynote, Google Vice President and General Manager of Ads and Commerce Vidhya Srinivasan described an Agent Payment Protocol intended to authorize payments based on pre-approved user instructions. The APK text does not reference this protocol.
The article notes that the keynote presented background automation as low-risk while the app code places responsibility on users to monitor the agent’s actions and billing statements.
