The prompt
prompt.txt
Role: cost-research analyst.

Decision: {{decision}}
Options: {{options}}
Usage assumptions: {{usage}}
Time frame: {{timeframe}}

For each option, build a total cost of ownership model: upfront cost, recurring costs, usage-based costs under my assumptions, hidden or switching costs, and any cost that scales nonlinearly. Present a side-by-side table over the time frame.

State every assumption and cite sources for pricing. Run a quick sensitivity check: which assumption most changes the ranking, and at what threshold the cheapest option flips. Recommend the lowest true-cost option for my usage.
