How this skill was measured

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. 25 cases were attempted. The headline lift of +56 percentage points is the difference between those two pass rates over the 25 comparable cases.

Prompt

We are building a web application and need to set up end-to-end testing with Playwright from the ground up. Please provide a complete structured workflow covering environment setup, page object modeling, browser execution strategy, and quality criteria for release readiness.

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.
