{"slug":"test-oracle-design","source_name":"test-oracle-design","name":"Test-oracle design","description":"Use when you need to test code whose correct output is hard to state directly — a large or complex result, a value that varies by input, a computation with no easy-to-write expected answer — and the reflex is to paste whatever the code returned once as the expected value. Chooses a test-oracle strategy (golden-master/snapshot, metamorphic relation, property/invariant, or cross-reference to a trusted implementation) by reasoning about WHY the output is hard to state. Not for choosing which input values to test, writing the test framework wiring, or triaging a flaky test.","version":1,"lift":{"pass_rate_delta_pts":null,"pass_rate_pct":20,"total_cases":15,"passed_cases":3,"tokens_delta_pct":488.4,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.5-flash","grading_method":"judged","completed_at":"2026-07-10T19:52:08.839032+00:00"},"skill_score":0.8787878787878789,"benchmark_models":[{"model":"gemini-3.5-flash","headline":false,"delta_pts":null,"with_pass_pct":null,"without_pass_pct":null,"tokens_delta_pct":488.4,"turns_delta_pct":0,"total_cases":15,"cases_aggregated":15,"verdict":"mixed","never_hurt":true,"completed_at":"2026-07-10T19:52:08.839032+00:00","run_id":"c7dbbaae-35cf-43ba-8b98-6bfc2fc2b4a7","latest_attempt":{"id":"c7dbbaae-35cf-43ba-8b98-6bfc2fc2b4a7","runner_model":"gemini-3.5-flash","overall_verdict":"mixed","completed_at":"2026-07-10T19:52:08.839032+00:00","gate":"not_comparable"},"version_number":1,"is_latest_version":true,"gate":"not_comparable"}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":false},"license":null,"install_count":3,"total_uses":70,"total_users":3,"manifest_hash":"fa8d224b2563a68d4c9b769fbb08a27f276203cbe427ca829741f489b8a17072","install_name":"test-oracle-design","version_id":"2d3d7ff9-6f10-481c-96f2-9595bcf55d4a","body_sha256":"75ebb55bb7b6de456a8af1f16a16544e6732d4e57b5c5282b9a8b49e9f182202","render_hash":"10b99bba00686714234fa9e259eb82367c6b4b46f1fe719b62b83c87cdf4a950","raw_url":"https://app.decimal.ai/s/test-oracle-design/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/test-oracle-design"}
