Skill UI

This skill guides the secure management and operation of Virtual Private Servers (VPS) and deployed server-side agents. Use it when SSH access, system restarts, log inspection, or complex workflow automation (like n8n or custom agents) is required on authorized remote hosts. It emphasizes following strict operational protocols and obtaining explicit user permission for sensitive actions.

A comprehensive guide covering scalable backend architecture patterns, including Repository, Service, and Middleware design. It details best practices for building robust APIs using Node.js, Express, and Next.js. Topics covered include RESTful API structuring, database query optimization (preventing N+1 issues), implementing database transactions, and integrating caching strategies like Redis. This guide is essential for developing high-performance, maintainable server-side applications.

A comprehensive guide covering production-level patterns and common pitfalls for using Prisma ORM in TypeScript backends. Learn best practices for schema design, optimizing queries using select/include, managing complex transactions, implementing singleton patterns, and mitigating issues in serverless environments and bulk operations.

A comprehensive guide detailing idiomatic React 18/19 patterns. Covers core principles like component purity, side effect management, hooks discipline, state location decision trees, and advanced topics such as Server/Client Component boundaries (RSC), Suspense, error handling, and using React 19 form actions for building robust, performant, and accessible UIs.

A specialized, downstream skill designed for forensic analysis within a confined sandbox environment, particularly for CTF challenges. It guides the user to inspect the full stack behavior, including API interactions, server routing, browser state (cookies, local storage), and asynchronous worker processes. Use this skill to trace complex, end-to-end request flows, debug authentication/session leaks, or diagnose discrepancies between frontend UI and backend enforcement.

This guide teaches how to build robust, event-driven gameplay in Godot 4.x using signals and node groups. It demonstrates how to decouple node communication by emitting custom signals (the observer pattern) and broadcasting actions to multiple nodes simultaneously using groups. Use this when a node needs to notify others of an event (e.g., item collected) or when you need to affect an entire category of nodes (e.g., pausing all enemies), eliminating the need for hard-coded scene references.

Build server-side call automation workflows using Azure Communication Services Java SDK. Supports IVR systems, call routing, recording, and AI-powered speech interactions. Includes DTMF recognition, text-to-speech, and webhook event handling for enterprise communication solutions.

Connect to Azure Database for PostgreSQL Flexible Server from Node.js/TypeScript using pg, with password and Microsoft Entra ID passwordless authentication, pooling, transactions, and parameterized queries.

Provision and manage fully managed relational databases on Google Cloud Platform, including PostgreSQL, MySQL, and SQL Server. Configure high availability, automated backups, security settings, and private IP connections. Suitable for production workloads requiring ACID transactions and regional failover. Includes Terraform configuration examples for infrastructure as code deployment.

This skill helps identify and exploit specific vulnerabilities in Next.js applications, such as Server Actions authentication bypasses, middleware bypasses, and SSRF via image optimization. It provides commands for fingerprinting, version detection, and testing attack vectors. Requires explicit written authorization for target scope.

A comprehensive guide providing best practices and architectural patterns for modern full-stack development using Next.js 14+ App Router. Covers advanced topics like Server Components, efficient data fetching, handling parallel routes, and implementing full-stack features with Server Actions for scalable React applications.

This guide provides expert patterns for implementing secure, full-stack authentication in Next.js using Supabase. It covers essential architectural components, including setting up separate browser and server clients, utilizing middleware for route protection and session refreshing, handling OAuth callbacks, and implementing auth operations safely via Server Actions and Server Components. Essential knowledge for building secure, modern web applications.
