A comprehensive pre-production audit tool that scans a codebase for critical issues across eight dimensions: security, database, deployment, code quality, AI/LLM usage, dependencies, frontend, and observability. It intercepts deployment commands, forcing users to resolve critical failures before shipping code. The audit is stack-agnostic and provides detailed pass/fail/manual reports.

This fixture is designed to verify basic compiler conformance and confirm target projection accuracy. It serves as a foundational testing tool in the compilation pipeline, ensuring that the compiler adheres to specified standards and correctly targets the intended platform architecture. Use it for early-stage validation of compiler output and system compatibility.

Generates professional PNG icon image sets for the Xcode Asset Catalog, supporting both massive open-source collections via Iconify API and native Apple symbols via SF Symbols. Use this tool to streamline the creation, search, and replacement of app icons, ensuring consistency in style, size, and color across your iOS project.

This skill guides developers on integrating CommunityToolkit.Mvvm ViewModels with Microsoft's Dependency Injection system. It covers setting up the composition root using the .NET Generic Host, managing service lifetimes (Singleton, Transient, Scoped), implementing constructor injection, and correctly registering messaging services (IMessenger) for robust, cross-platform XAML applications (WPF, MAUI, Uno, Avalonia).

The CommunityToolkit.Mvvm Messenger provides a robust Publish/Subscribe messaging system for ViewModels and other objects. It allows multiple components to communicate asynchronously without holding direct references, effectively eliminating tight coupling. Supports various messaging patterns, including simple value broadcasts, request/reply (sync/async), and collection requests, making it ideal for complex applications using WPF, WinUI 3, .NET MAUI, or Avalonia.

A comprehensive tool for monitoring SEO performance changes. It captures baselines of critical on-page SEO elements (titles, meta tags, headings, Core Web Vitals) and detects regressions or "drift" over time. Use it to compare current page states against stored standards to ensure consistent SEO integrity after updates or deployments.

Provides a comprehensive toolkit for integrating X API functionality into applications, data pipelines, and AI agents. Features include robust tweet searching, user profile lookups, timeline fetching, media downloading, and webhook monitoring. Supports multiple languages via official SDKs, REST APIs, and MCP server integration for advanced automation workflows.

Diagnoses full-stack failure modes in agent and LLM applications, including wrapper regressions, memory contamination, tool discipline failures, hidden repair loops, and rendering corruption. Produces severity-ranked findings and code-first fixes for production agent systems.

This comprehensive guide covers best practices for building modern Angular applications. It provides detailed instructions on component architecture, state management using Signals, advanced routing, dependency injection, handling forms (prioritizing Signal Forms), and implementing accessibility (ARIA). It also details setup procedures for new projects and modern rendering strategies like SSR.

This guide provides comprehensive, structured error handling patterns for modern applications using TypeScript, Python, and general architectural principles. It covers essential concepts like typed custom errors, Result patterns, API error transformers, and React Error Boundaries. Learn how to implement fail-fast mechanisms, differentiate user-facing messages from developer logs, and ensure system resilience against unexpected failures.

Comprehensive patterns and tools for writing robust tests for F# applications within the modern .NET ecosystem. This guide covers unit testing (xUnit, FsUnit), property-based testing (FsCheck), mocking dependencies (NSubstitute), and full integration testing (WebApplicationFactory). Ideal for improving test coverage, validating complex business logic, and establishing a resilient testing infrastructure.

This utility serves as a Command Line Interface (CLI) alias for specialized AI code models, specifically mapping to the Claude Code `/pua:yes` command structure. It facilitates structured code generation or interaction by adopting a specific 'yes skill' protocol. It ensures that while switching to an encouragement-first narration, the system maintains strict verification red lines and handles configuration file updates while preserving unknown fields. Ideal for developers needing consistent, protocol-driven AI code assistance.
