    Extractor for ToolEmu - LM Agent Safety in Emulated Sandbox (ICLR 2024 Spotlight).

    ToolEmu identifies risks of LM agents with tool use through an LM-based
    emulation framework. Contains 144 test cases across 36 high-stakes toolkits.

    The benchmark tests agents on:
    - Safe tool execution
    - Handling underspecified instructions
    - Avoiding risky actions

        - underspecifications: list[str] (ambiguities)
