UnverifiedThe triggers for silent drift often come from external sources, such as version upgrades of the underlying large model, fine-tuning of API behavior, or changes to tool interfaces—modifications that are not in the codebase yet directly alter Agent behavior.72% similarUnverifiedPrompt的细微改动、模型配置变化、工具Schema的修改都可能引发Agent工具调用行为的退化69% similarUnverifiedCompositional failure refers to a situation where individual tool calls are each compliant, but chaining multiple tools across services may collectively cause harm.68% similarUnverifiedAction sequence-based task definitions are tightly coupled to specific UI layouts, causing any interface update to potentially invalidate existing benchmark tests68% similarUnverified多步骤工具调用链（Tool Calling Chain）任务要求模型具备状态追踪、错误恢复、上下文持续理解等能力，任何中间步骤失败都会导致整体任务崩溃67% similar
