An AI developer significantly reduced token costs and improved agent performance by refactoring a monolithic 600-line script into a harness architecture. The original script repeatedly sent large amounts of irrelevant historical data and tool outputs in its prompts, leading to excessive token consumption and degraded model quality. The new harness separates the model from its surrounding logic, implementing explicit state management by summarizing progress to disk rather than carrying the entire conversation history in each prompt, which cut costs by approximately 40%.
