Summary

WikiTrace links distilled lessons back to trajectory summaries and raw evidence so an agent can challenge bad advice before acting.

External agent memory can degrade performance when a concise lesson is wrong, misread or applied outside its original context. WikiTrace stores each lesson with a summary of why its source trajectory succeeded or failed and a link to the raw trajectory. When a lesson is underspecified, conflicts with another or comes from failure, the agent can descend through those links before acting. Across five agent benchmarks, the authors report that evidence-linked memory outperformed lesson-only baselines and reduced memory-induced degradation.
