Generalization of Context-Rot Error Distributions Beyond Deep Search

Determine whether the error distributions observed for context rot in long-horizon deep search tasks fully generalize to other long-horizon agentic domains, such as software development.

Background

The paper evaluates context rot exclusively in long-horizon agentic deep-search tasks, using open-source LLMs and search-oriented benchmarks. Its reported error distributions concern terminal states such as give-up outcomes and uncertain answers that arise as accumulated context grows.

The authors explicitly leave unresolved whether these observed distributions are specific to deep-search settings or also occur in other long-horizon agentic domains, including software development. Establishing the scope of this generalization would clarify how broadly the paper's diagnostic findings apply across agentic applications.

References

Additionally, because our investigation is specifically centered on long-horizon deep search tasks, it remains unclear whether the error distributions we observed fully generalize to other long-horizon agentic domains like software development.
