Ghost Tool Calls: Issue-Time Privacy for Speculative Agent Tools
Researchers identify a privacy vulnerability in AI agents that use speculative tool calls to reduce latency, where external services receive and retain inferred user intent data even after the agent abandons the speculative branch. The study proposes Speculative Tool Privacy Contracts as a runtime solution, finding that only issue-time policies suppressing or modifying calls before dispatch effectively mitigate information leakage.
