Use when asked should I take job A or B, which one should I buy, help me decide, or make a pro/con list. Produces the criteria that matter (weighted by what you care about), the options scored against them, a clear recommendation with its confidence, and the single question that would flip the decision if you're still torn.

Pro/con lists fail because they treat every point as equal and stop before deciding. This does the honest version: it pulls out the criteria that actually matter to you, weights them, scores each option, and then commits to a recommendation — while naming the one unknown that, if resolved, would change the answer. It helps you decide, not just organise the agonising.

Tiebreaker: the one thing to find out — question]. Gut-check: does the winner sit right? If not, what's the unnamed criterion?

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +59 percentage points is the difference between those two pass rates over the 22 comparable cases. 2 cases got worse with the skill loaded, and they are included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
