Your prompt has a budget. Do you know what is spending it? That copied thread, repeated log, and old instruction all become part of the context you ask AI to work with. Try this starter challenge: 1. Pick one fictional task. 2. Put its essential facts and constraints in a short text file. 3. Keep a second version with the extra background. Which one fits your chosen text budget—and what would you lose by trimming it? The full guide supplies a local token counter, two practice files, and the missing setup steps. Our synthetic examples counted 396 and 44 text tokens. We did not test answer quality, cost savings, or faster responses.
