STAGE-Claw is an automated framework for state-based benchmarking of large language model (LLM)-powered agents, evaluating their performance in realistic personal computing environments. The framework automatically generates and validates diverse tasks, provides process-aware diagnostics, and showed that state-based evaluation can expose agent performance overestimation by output-only methods, with Claude-Opus-4.7 achieving the highest average score of 77.1% among 11 frontier LLMs.

Key insights

  • State-based evaluation, which assesses actual persistent state changes in real applications, is crucial for accurate agent assessment, as output-only methods can significantly overestimate performance by missing real-world execution failures.
  • The quality of an agent's planning, tool selection, and result verification is more critical than the sheer volume of tool invocations for successful task completion.
  • Persistent memory quality, including handling noise, misleading information, and conflicts, profoundly impacts agent decisions and downstream state updates, indicating a need for advanced memory management mechanisms.
