Why Retrying Fails: Context Contamination in LLM Agent Pipelines

arXiv cs.AI · yesterday Cached

This paper introduces the Context-Contaminated Restart Model (CCRM) to formally analyze how failed attempts in LLM agent pipelines contaminate context and increase error rates during retries. It provides theoretical proofs and validates the model against SWE-bench data, showing significant discrepancies with standard independent models.
