Complements `design-an-interface` (which is interface-agnostic) by covering HTTP-specific concerns like status codes, cache headers, and breaking-change management.","version":1,"lift":{"pass_rate_delta_pts":18.18,"pass_rate_pct":90.9,"total_cases":22,"passed_cases":20,"tokens_delta_pct":65.4,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-09-27T22:59:43.749334+00:00"},"skill_score":0.9091,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":18.18,"with_pass_pct":90.9,"without_pass_pct":72.7,"tokens_delta_pct":65.4,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":22,"verdict":"mixed","never_hurt":false,"completed_at":"2026-09-27T22:59:43.749334+00:00","run_id":"ab6371cb-ccc6-4a65-b00a-0717eb1c8677","latest_attempt":{"id":"ab6371cb-ccc6-4a65-b00a-0717eb1c8677","runner_model":"gemini-3.6-flash","overall_verdict":"mixed","completed_at":"2026-09-27T22:59:43.749334+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":"269c5191c34d59e1019ac1415d99f0edfe40d77c2175c32ac2801445b735104b","install_name":"gsd-build-api-design","version_id":"d974ae20-205d-4e23-8e27-325135e0ebc3","body_sha256":"269c5191c34d59e1019ac1415d99f0edfe40d77c2175c32ac2801445b735104b","render_hash":"111bee5b5b3477538b1137c9682fba866bbc10f087caec6da53657bc0d70f096","raw_url":"https://app.decimal.ai/s/gsd-build-api-design/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/gsd-build-api-design"}
