Key Points

  • The paper introduces LiveClawBench, a benchmarking approach aimed at evaluating LLM agents on complex, real-world assistant tasks rather than isolated or fully specified challenges.
  • It identifies a gap in existing benchmarks’ ability to reflect compositional difficulty seen in deployment and proposes a Triple-Axis Complexity Framework to model task difficulty.
  • Task difficulty is characterized along three dimensions: Environment Complexity, Cognitive Demand, and Runtime Adaptability, based on analysis of real OpenClaw usage cases.
  • A pilot benchmark is built with explicit complexity-factor annotations, covering real assistant tasks with compositional difficulty to enable more principled evaluation.
  • The authors plan to expand case collections to broaden coverage across domains and the complexity axes.

Abstract

LLM-based agents are increasingly expected to handle real-world assistant tasks, yet existing benchmarks typically evaluate them under isolated sources of difficulty, such as a single environment or fully specified instructions. This leaves a substantial gap between current evaluation settings and the compositional challenges that arise in practical deployment. To address this gap, we introduce LiveClawBench, a benchmark to evaluate LLM agents on real-world assistant tasks. Based on an analysis of various real OpenClaw usage cases, we derive a Triple-Axis Complexity Framework that characterizes task difficulty along three dimensions: Environment Complexity, Cognitive Demand, and Runtime Adaptability. Guided by this framework, we construct a pilot benchmark with explicit complexity-factor annotations, covering real-world assistant tasks with compositional difficulty. Together, the framework and benchmark provide a principled foundation for evaluating LLM agents in realistic assistant settings, and establish a basis for future expansion across task domains and complexity axes. We are continuing to enrich our case collections to achieve more comprehensive domain and complexity coverage. The project page is at https://github.com/Mosi-AI/LiveClawBench.
