HarnessRisk: A Lifecycle-Oriented Benchmark for Agent Harness Safety
HarnessRisk, a lifecycle oriented benchmark that organizes agent harness safety into six operational phases including Harness Configuration, Capability Extension, Runtime Operation, State Persistence, Action Control, and Incident Recovery, finds that explicit risk recognition does not reliably lead to safe action as some configurations detect risks in more than 90% of runs while retaining substantial attack success.
