One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.

1 of 5

Prompt

Here are our Q3 figures vs budget for our UK division: - Revenue: Budget £1.2M, Actual £1.05M - Cost of Sales: Budget £500k, Actual £480k - Operating Expenses: Budget £350k, Actual £410k Our materiality threshold is £20k. Context: enterprise deal closures slipped into Q4 and software renewals came in higher than planned. Target audience is the CFO. Please prepare a report containing a clear variance summary grid, detailed commentary for significant line items, a priority ranking of top variances, updated full-year forecast expectations, and a short executive summary suitable for a board meeting.
