LLM Agent Planning: Does Hierarchical Decomposition Improve Web Task Success?
Hierarchical task decomposition generally improves the success rate of LLM-based agents on web navigation tasks compared to flat planning approaches. While specific frameworks demonstrate measurable performance gains on benchmarks like WebArena, the field currently lacks a direct head-to-head comparison between hierarchical and non-hierarchical methods across all task types. Existing evidence suggests that hierarchical structures help manage long-horizon tasks, though low-level execution remains a primary bottleneck.
