Great writeup from the University of Oxford. It's a taxonomy of LLM-based agent limitations. Good read for anyone shipping with agents. Benchmark scores keep climbing, yet the same agent failures resurface across otherwise unrelated evaluations, hidden behind the leaderboard. This work synthesizes 27 benchmark, taxonomy, and audit papers spanning 19 benchmarks into the first cross-cutting taxonomy of LLM-agent limitations. Six failure clusters emerge: Tool invocation and parameter errors, planning and constraint-satisfaction failures, long-horizon degradation from context accumulation, multi-agent coordination breakdowns, safety failures under adversarial or underspecified conditions, and measurement validity problems. Failures compound nonlinearly with task length, strong sub-task scores do not add up to end-to-end success, and adding scaffolding does not reliably improve reliability.
