Relax. We're not going to explain this chapter like a textbook — just like a friend talking you through it, in plain, easy-to-follow terms.
Let's think about it this way for a second
A beginner's budget is simple. About half goes to evidence. One slot goes to the prompt plus constraints. The rest goes to the question and the format. Chat history shouldn't steal space from that first half. You don't need a token counter yet. Draw three boxes on paper. Eyeball which box is biggest. If history is the biggest box, your budget is broken.
Let's connect it to everyday life
A mock page — top: 3 lines of goal. Middle: 8 lines of notes. Bottom: 2 lines of question. If the notes balloon to 40 lines, trim them. Use RAG to pull just enough. Or keep just one heading. Don't fill up a slot just because "it might get read later" — that's like stuffing every piece of clothing you own into a suitcase.
Let's try it out together
Page budget
15% goal + constraints
60% evidence notes
25% question + output shape
If notes overflow → cut notes, not the questionBudget a turn across three slots.5-Minute Try
Draw three boxes on paper. For one of your own questions, write what goes in each box.
One Quick Heads-Up
Without a budget, the loudest text hogs all the space and the important stuff disappears.
