ORM

CPU/memory profiling, database query optimization, and performance analysis

Windows platform patterns for native application development. Use when writing Windows C++, handling input, managing threads, or working with Win32/COM APIs. Covers message queues, keyboard hooks, SendInput batching, COM resource management, and QueryPerformanceCounter timing.

Systematic debugging approach for Rust async code with Tokio, Turso, and redb. Use when diagnosing runtime issues, performance problems, async deadlocks, database connection issues, or panics.

Database schema validation, data integrity testing, migration testing, transaction isolation, and query performance. Use when testing data persistence, ensuring referential integrity, or validating database migrations.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Executes tdx CLI commands for Treasure Data. Covers `tdx databases`, `tdx tables`, `tdx query`, `tdx auth setup`, context management with profiles/sessions, and output formats (JSON/TSV/table). Use when users need tdx command syntax, authentication setup, database/table exploration, or query execution.

Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Expert FastAPI developer specializing in production-ready async REST APIs with Pydantic v2, SQLAlchemy 2.0, OAuth2/JWT authentication, and comprehensive security. Deep expertise in dependency injection, background tasks, async database operations, input validation, and OWASP security best practices. Use when building high-performance Python web APIs, implementing authentication systems, or securing API endpoints.

ゼロダウンタイム戦略、データ変換、ロールバック手順を使用して、ORM間およびプラットフォーム間でデータベース移行を実行します。データベースの移行、スキーマの変更、データ変換の実行、またはゼロダウンタイムデプロイメント戦略の実装時に使用します。

Process JSON with jq and YAML/TOML with yq. Filter, transform, query structured data efficiently. Triggers on: parse JSON, extract from YAML, query config, Docker Compose, K8s manifests, GitHub Actions workflows, package.json, filter data.

Expert in database schema design with focus on normalization, indexing strategies, FTS optimization, and performance-oriented architecture for desktop applications

Use when reviewing WordPress PHP code for performance issues, auditing themes/plugins for scalability, optimizing WP_Query, analyzing caching strategies, or detecting anti-patterns in database queries, hooks, object caching, AJAX, and template loading.

Downloads Dutch official legal publications including national laws (wetten, ministeriele regelingen, koninklijk besluiten), local regulations (lokale verordeningen, gemeentelijk beleid), and implementation policies (uitvoeringsbeleid) from government databases (BWB, CVDR) and converts them to YAML format with textual content only. Use when user wants to download, fetch, or import any Dutch regulation by name or type.

Expert Celery distributed task queue engineer specializing in async task processing, workflow orchestration, broker configuration (Redis/RabbitMQ), Celery Beat scheduling, and production monitoring. Deep expertise in task patterns (chains, groups, chords), retries, rate limiting, Flower monitoring, and security best practices. Use when designing distributed task systems, implementing background job processing, building workflow orchestration, or optimizing task queue performance.

Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Creates database migrations with proper schema changes, data migrations, and rollback support for various ORMs (Prisma, TypeORM, Alembic, etc.). Use when managing database schema changes.

This skill enables Claude to aggregate and centralize performance metrics from various sources. It is used when the user needs to consolidate metrics from applications, systems, databases, caches, queues, and external services into a central location for monitoring and analysis. The skill is triggered by requests to "aggregate metrics", "centralize performance metrics", or similar phrases related to metrics aggregation and monitoring. It facilitates designing a metrics taxonomy, choosing appropriate aggregation tools, and setting up dashboards and alerts.

Platform-specific building systems for mobile, VR, and accessibility. Use when implementing touch controls for building games, VR spatial input, colorblind-friendly feedback, or cross-platform building mechanics. Covers input adaptation and inclusive design patterns.

Use when analyzing and improving performance for database queries, API endpoints, or frontend rendering.

Builds phased data and system migrations using feature flags, dual writes, backfills, and validation. Includes rollback plans and risk mitigation. Use for "data migration", "system migration", "database migration", or "platform migration".
