A Stanford study categorizes agent failures into process errors (loops, budget exhaustion) fixable by harness edits, and content errors (poor planning) requiring weight fine-tuning. Experiments show harness evolution improved Qwen3.5-4B scores from 0.16 to 0.30 but failed to reduce bad plans, whereas a LoRA adapter cut poor plan rates in Qwen3.5-9B from 28% to 5%. This establishes a diagnostic framework for optimizing agents.

    • Agent failures split into process errors (loops/stalls) and content errors (bad plans), requiring distinct fixes.
    • Harness edits improve task completion rates but cannot fundamentally enhance the model's planning logic quality.
    • Weight fine-tuning (e.g., LoRA) is more effective than prompt engineering alone for reducing poor planning outputs.
