Use when asked to \"design an interface\", \"shape this API\", \"design it twice\", \"explore module boundaries\", or when planning a new deep module and the first idea is unlikely to be the best. Based on \"Design It Twice\" from A Philosophy of Software Design — the value is the contrast, not the first draft.","version":1,"lift":{"pass_rate_delta_pts":-69.23,"pass_rate_pct":16.7,"total_cases":24,"passed_cases":4,"tokens_delta_pct":-22.5,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-09-27T23:12:01.756326+00:00"},"skill_score":null,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":-69.23,"with_pass_pct":15.4,"without_pass_pct":84.6,"tokens_delta_pct":-22.5,"turns_delta_pct":0,"total_cases":24,"cases_aggregated":21,"verdict":"mixed","never_hurt":false,"completed_at":"2026-09-27T23:12:01.756326+00:00","run_id":"a1bece07-d11c-47e2-8c75-8c5fc3843289","latest_attempt":{"id":"a1bece07-d11c-47e2-8c75-8c5fc3843289","runner_model":"gemini-3.6-flash","overall_verdict":"mixed","completed_at":"2026-09-27T23:12:01.756326+00:00","gate":null},"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,"total_uses":0,"total_users":0,"manifest_hash":"767a984f941239b44420fb5df6d3793f950c54ce3a64a782a6f7b90a27d3647c","install_name":"gsd-build-design-an-interface","version_id":"3e99218a-29a0-476d-b1aa-b2925f142125","body_sha256":"767a984f941239b44420fb5df6d3793f950c54ce3a64a782a6f7b90a27d3647c","render_hash":"038c6675f36f4ffc058bde88e86df779467652be762eb97809a4102b0c5ade44","raw_url":"https://app.decimal.ai/s/gsd-build-design-an-interface/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/gsd-build-design-an-interface"}
