Use when the user asks to find weak or shallow tests, discover untested edge cases, or check whether tests would catch a bug — e.g. \"would my tests catch it if someone changed the code\", \"would a subtle logic or boundary change slip past the current tests\", \"are my tests strong enough to catch a subtle bug\". Evaluates test effectiveness through mutation-style reasoning: analyzes mutation points (","version":1,"lift":{"pass_rate_delta_pts":13.64,"pass_rate_pct":77.3,"total_cases":22,"passed_cases":17,"tokens_delta_pct":267.7,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-09T13:59:24.616818+00:00"},"skill_score":0.7727,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":13.64,"with_pass_pct":77.3,"without_pass_pct":63.6,"tokens_delta_pct":267.7,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":18,"verdict":"mixed","never_hurt":false,"completed_at":"2026-08-09T13:59:24.616818+00:00","run_id":"169cafb8-7919-4a27-8c57-184cbec54703","version_number":1,"is_latest_version":true,"gate":null}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":"MIT","install_count":0,"manifest_hash":"002d1c21e0af7d8132f64734736df14d223a9a6c4f84049f5ed636ae09f8210c","raw_url":"https://app.decimal.ai/s/dotnet-test-gap-analysis/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/dotnet-test-gap-analysis"}
