Identifies CPU, memory, and I/O bottlenecks, generates flamegraphs, analyzes bundle sizes, optimizes database queries, runs load tests with k6 and Artillery. Always measures before and after. Use when investigating a slow endpoint, planning a performance budget, or hunting a memory leak in production.","version":1,"lift":{"pass_rate_delta_pts":13.64,"pass_rate_pct":86.4,"total_cases":22,"passed_cases":19,"tokens_delta_pct":6.1,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-11T10:01:10.149362+00:00"},"skill_score":null,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":13.64,"with_pass_pct":86.4,"without_pass_pct":72.7,"tokens_delta_pct":6.1,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":19,"verdict":"mixed","never_hurt":true,"completed_at":"2026-08-11T10:01:10.149362+00:00","run_id":"b8753d7b-58e0-454d-b15b-4fcd5c1c4e25","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":"3467c66e61db34cbbf9e9fd722289acd1278fa15e4314cf92ec493908d8e5973","raw_url":"https://app.decimal.ai/s/alirezarezvani-performance-profiler/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/alirezarezvani-performance-profiler"}
