Craft a detailed prompt for the 'Financial Modeler' agent (primarily using GPT-5) that leverages extended thinking for calculating complex ROI. The prompt should instruct GPT-5 to break down the problem into sub-steps (e.g., calculate direct savings, indirect benefits, discounted cash flow), consider various economic factors (inflation, discount rate), and iteratively refine its model. Include instructions for using intermediate thought steps and adaptive reasoning budgets.

Adaptation plan

Keep the source stable, then change the prompt in a predictable order so the next run is easier to evaluate.

Keep stable

Hold the task contract and output shape stable so generated implementations remain comparable.

Tune next

Update libraries, interfaces, and environment assumptions to match the stack you actually run.

Verify after

Test failure handling, edge cases, and any code paths that depend on hidden context or secrets.
