Total time is 1 hour 15 minutes, total cost is approximately $40. Sonnet 5 is offered at a special launch price of $2/M input and $10/M output until August 31, 2026, after which it will switch to the standard price of $3/$15. The /goal command requires the latest version of Claude Code (claude update). You can use /goal without PRD, but the quality will decrease; I recommend using both together.
