Use when you have test results vs a gold standard (binary 2x2, or a continuous score + true labels) and need to judge how good the test is, pick a threshold, or compute the probability of disease given a result. Emphasizes the prevalence-dependence of PPV/NPV.","version":2,"lift":{"pass_rate_delta_pts":22.73,"pass_rate_pct":81.8,"total_cases":22,"passed_cases":18,"tokens_delta_pct":56.1,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-02T18:31:14.155334+00:00"},"skill_score":0.8182,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":22.73,"with_pass_pct":81.8,"without_pass_pct":59.1,"tokens_delta_pct":56.1,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":19,"verdict":"mixed","never_hurt":true,"completed_at":"2026-08-02T18:31:14.155334+00:00","run_id":"729ec846-e589-4ce2-880d-489a161040d8","version_number":2,"is_latest_version":true,"gate":null}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":"Apache-2.0","install_count":0,"manifest_hash":"ebfd4a3014c8f8d4dec1928e4f5f13b47aec525920866228da03554f56f925ac","raw_url":"https://app.decimal.ai/s/tooluniverse-diagnostic-test-evaluation/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/tooluniverse-diagnostic-test-evaluation"}
