performance-profiling
by lv416e
"Use when investigating performance issues, before attempting any optimization - four-phase methodology (baseline measurement, bottleneck profiling, complexity analysis, targeted optimization) that ensures data-driven decisions over gut-feel tuning パフォーマンスの問題を調査する際、最適化を試みる前に使用 - 4フェーズ手法（ベースライン測定、ボトルネックプロファイリング、計算量分析、的を絞った最適化）により、直感的なチューニングではなくデータに基づく判断を保証"

claude-code-plugins
by melodic-software
"Draw an entity-relationship diagram from committed schema declarations, with no database connection. Prisma models win over Entity Framework fluent mappings, which win over SQL migrations, and a disagreement is reported. Use when: 'map data', 'ERD', 'entity relationship', 'schema diagram', 'cardinality from mappings', 'which tables relate'. Skip when: the question is deployment topology, runtime state, or data volume."
