Suite of tools for creating elaborate, multi-component HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
Build prompts for Effect AI using messages, parts, and composition operators. Covers the complete Prompt API for constructing, merging, and manipulating conversations with language models.
Guides architectural decisions for LangGraph applications. Use when deciding between LangGraph vs alternatives, choosing state management strategies, designing multi-agent systems, or selecting persistence and streaming approaches.
Search ComfyUI codebase and custom nodes using the comfy-codesearch service. Use when the user wants to find code examples, search for specific functions, or explore ComfyUI repositories.
Master orchestration skill for Quest Keeper AI development. Use when working on ANY part of Quest Keeper AI - coordinates between frontend (Tauri/React), backend (rpg-mcp), and documentation. Triggers on any mention of Quest Keeper, rpg-mcp, game development for this project, or when referencing the Agents/ folder.
Refactor code to improve clarity and maintainability without changing behavior. Use when improving readability, reducing complexity, or eliminating duplication.
Don't Repeat Yourself (DRY) and Never Reinvent the Wheel (NRtW) - core b00t principles. Use existing libraries, leverage Rust via PyO3 instead of duplicating logic in Python, and contribute to upstream projects rather than fork privately.
Guide for creating C4 model design documents. Use this when asked to create architecture designs, system context diagrams, container diagrams, or component diagrams following the C4 model methodology.
Guide for applying MUSUBIX's 17 learned best practices. Use this when asked about coding patterns, design patterns, or testing patterns that MUSUBIX recommends.
Guide for creating Architecture Decision Records (ADRs). Use this when asked to document architecture decisions, technology choices, or design trade-offs.
Modern React patterns for TypeScript applications including hooks, state management, and component composition. Use when building React components, managing state, or implementing React best practices.
Implement Effect services as fine-grained capabilities avoiding monolithic designs
Create production-ready Effect domain models using Schema.TaggedStruct for ADTs, Schema.Data for automatic equality, with comprehensive predicates, orders, guards, and match functions. Use when modeling domain entities, value objects, or any discriminated union types.
Design and compose Effect layers for clean dependency management
Expert guidance on Swift Concurrency concepts. Use when working with async/await, Tasks, actors, MainActor, Sendable, isolation domains, or debugging concurrency compiler errors. Helps write safe concurrent Swift code.
Master declarative parameter systems with Param for type-safe configuration. Use this skill when building parameterized classes with automatic validation, creating reactive dependencies with @param.depends, implementing watchers for side effects, auto-generating UIs from parameters, or organizing application configuration with hierarchical parameter structures.
Decide between Context Tag witness and capability patterns for dependency injection, understanding coupling trade-offs
World-class Java and Spring Boot development skill for enterprise applications, microservices, and cloud-native systems. Expertise in Spring Framework, Spring Boot 3.x, Spring Cloud, JPA/Hibernate, and reactive programming with WebFlux. Includes project scaffolding, dependency management, security implementation, and performance optimization.
Reduce complexity by revealing information progressively. Use when designing onboarding, complex forms, feature-rich interfaces, or any experience where showing everything at once would overwhelm users.
The Composable Architecture (TCA) - A library for building Swift applications with state management, composition, and testability
Extracts system architecture and creates data flow documentation (Stages 1, 2, 6). Focuses on source traceability and accurate information extraction. Does NOT perform security analysis or quality validation.
Comprehensive security engineering skill for application security, penetration testing, security architecture, and compliance auditing. Includes security assessment tools, threat modeling, crypto implementation, and security automation. Use when designing security architecture, conducting penetration tests, implementing cryptography, or performing security audits.
Create a new event-sourced aggregate with proper Apply methods, event handling, and Marten configuration. Use this when adding a new domain entity that needs event sourcing.
Create a new Marten read model projection for CQRS queries. Use this when you need to create an optimized read model from event streams.
