About

Derived from TS-Bench AgentDojo-Traj, it translates only user instructions into German, French, Turkish, Swahili, and Amharic while keeping tool calls and labels identical. It includes English paraphrase and whitespace controls.

It measures verdict flip rates across 19 guards. Findings show small and purpose-built guards are highly sensitive to language, with error rates increasing for rarer languages, while frontier guards remain robust.
