Lantern Candles cost kit

Use it with course 4, lesson 5. Lantern Candles is a made-up candle shop whose order agent goes from 3,000 to 30,000 orders a month.

prices.csv is Anthropic's list prices for three models, in US dollars per million tokens, read from Anthropic's pricing page (platform.claude.com/docs/en/about-claude/pricing) on 10 November 2026. Prices change, so check the page before you rely on them.

assumptions.txt says how often the agent runs, how many tokens each run uses, and which five options to price. The numbers are made up.

Open this folder in the Code tab and paste the build prompt from the lesson. Claude builds the cost table from these two files. Nothing here calls Claude or costs money beyond your Claude plan.
