A comprehensive guide to best practices for data access and persistence in Spring Boot using JPA and Hibernate. Covers critical topics such as entity modeling, relationship management (preventing N+1), transaction handling, query optimization, indexing strategies, and connection pooling.

A comprehensive guide to building robust database layers in Kotlin using the Exposed ORM framework. It covers advanced patterns including DSL queries, DAO entity management, transaction handling, connection pooling with HikariCP, schema migration via Flyway, and implementing the Repository pattern for clean, production-grade data access.

This skill provides access to the Anthropic Claude Managed Agent runtime, which is a cloud-native, persistent environment for running complex, long-running, or asynchronous AI tasks. Unlike local WASM agents, the managed runtime provides a full container, persistent filesystem, and robust state management across multiple turns. It supports the entire agent lifecycle: creation, prompting, status inspection, event logging, and mandatory termination.

This skill transforms you into an expert design system guideline author, specializing in creating structured, implementation-ready documentation for the Power brand. It provides a comprehensive workflow covering style foundations (color, typography, spacing), component anatomy, accessibility standards (keyboard-first, high contrast), and quality gates. Use it to ensure all digital products maintain superior aesthetic consistency, usability, and accessibility.

A comprehensive guide to architectural patterns for building cloud-native, event-driven microservices using Quarkus 3.x. Covers RESTful API design with JAX-RS, implementing event messaging with Apache Camel and RabbitMQ, structured data access using Hibernate Panache, managing transactions, and advanced logging context handling (MDC). Ideal for developers building robust, scalable, and maintainable enterprise systems.

This comprehensive guide covers security best practices for building robust Quarkus applications. It details how to implement secure authentication (JWT, OIDC), role-based authorization (RBAC), robust input validation (Bean Validation), and advanced protection against vulnerabilities like SQL injection and CSRF. Essential for securing resource access and managing application secrets.

A comprehensive guide to best practices for building production-ready React Native and Expo applications. Covers core concepts including Expo Router navigation, state management separation, robust data fetching with TanStack Query and Zod, efficient list rendering, styling consistency, and accessing native APIs.

A comprehensive guide detailing idiomatic React 18/19 patterns.
