AI agent refactor slashes token costs by 40% with new harness

By PulseAugur Editorial · [1 sources] ·

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%.

    I Rebuilt My AI Agent From a 600-Line Script Into a Harness. Token Cost Dropped 40%.

    <h2> The 600-line script that ate my API budget </h2> <p>My first real agent was one Python file. About 600 lines. It read a task, pulled in everything it might conceivably need -- the full repo tree, every doc, the entire conversation history, all tool definitions -- jammed it i…
