Skill UI

This comprehensive guide demonstrates how to achieve highly testable Swift code using protocol-based dependency injection. By abstracting external concerns—such as file systems, networking, and external APIs—into small, focused protocols, developers can write deterministic unit tests that mock side effects and error paths, ensuring robust architecture across different environments (App, Test, Preview).

A comprehensive skill guide for implementing all forms of data fetching and networking in React Native/Expo environments. Covers best practices for using the native fetch API, managing state with React Query (TanStack Query), implementing robust error handling with retry logic, handling offline scenarios, and securely managing authentication tokens. Essential for building reliable, scalable mobile applications that interact with external APIs.

A comprehensive guide and Python tool for reverse engineering Rust-compiled malware. It addresses unique Rust binary challenges, such as non-null-terminated strings and monomorphization. The script extracts crate dependencies, identifies suspicious capabilities (like networking or encryption), and filters for malware-related strings, assisting security researchers in deep binary analysis.

A comprehensive architectural guide for building and maintaining macOS menubar utilities using SwiftUI and Tuist. It enforces strict separation of concerns by guiding developers to keep networking, state management, and UI presentation in distinct, testable layers, ensuring robust and scalable application development.

A comprehensive guide to idiomatic and robust Dart/Flutter patterns. Covers essential topics including null safety, immutable state management (Freezed), advanced state solutions (BLoC, Riverpod, Provider), reactive routing with GoRouter, secure networking using Dio, and implementing Clean Architecture principles. Ideal for setting up new, scalable Flutter projects.

Fetches real-time Azure retail prices from the public Azure Retail Prices API and guides credit estimations for Copilot Studio agents, covering compute, storage, networking, databases, AI, and Copilot billing scenarios.

This skill guides users through setting up robust, production-grade infrastructure on Fly.io. It covers creating and connecting to Fly Postgres clusters for reliable data storage, provisioning persistent NVMe Volumes for durable file storage, and configuring private internal networking (6PN) for secure service-to-service communication. It is essential for modern microservices requiring stable databases and persistent state.

This comprehensive guide provides essential security best practices for deploying applications on Fly.io. It covers critical areas such as secrets management, private networking using WireGuard, securing TLS certificates, and properly scoping deploy tokens. The included functions demonstrate how to validate API tokens, verify webhook signatures, and validate deployment configurations to mitigate common cloud and application-level vulnerabilities.

This comprehensive runbook provides a self-service solution for managing Oracle Cloud Infrastructure (OCI) outages when official status pages are misleading or silent. It guides users through independent service health probes (Identity, Compute, Networking), automated instance recovery actions (reboot, softreset), and critical procedures for cross-Availability Domain (AD) or cross-region failover using boot volume backups to ensure business continuity.

This skill provides a powerful mechanism for modifying and extending AWS infrastructure using Pulumi handlers and dedicated declarative components. It allows developers to manage complex cloud setups, including configuring OpenSearch, VPC networking, resource tagging, custom domains, blue-green deployment strategies, and implementing environment-conditional configurations (e.g., production vs. development).

This assistant guides users through managing Azure resources entirely via the command line using the Azure CLI (`az`). It identifies the correct commands, prompts for missing required parameters (like resource groups or locations), constructs the full command sequence, executes the action, and diagnoses any output errors to ensure successful deployment and configuration of services across Compute, Networking, and other Azure domains.

A comprehensive reference for the `uc` CLI, designed for managing decentralized, self-hosted clusters. Use this skill to deploy services via Docker Compose, configure advanced networking, and manage infrastructure components like machines, volumes, and ports. Supports Caddy ingress routing, WireGuard networking, and scaling across peer machines, making it ideal for robust, highly available self-hosting environments.
