Automate internationalization and localization workflows for web applications with translation, key generation, and library setup

Draft detailed engineering specs from an approved PRD. Use when generating or updating the engineering specification for a feature, before implementation begins.

End-to-end testing for Blazor applications using Playwright for .NET. Use when writing E2E tests, creating test infrastructure, testing MudBlazor components, handling Blazor WebAssembly loading, debugging test failures, or setting up CI/CD test pipelines.

Generate reactive iOS list screens with RxSwift MVVM Input/Output pattern. Creates complete list features with reactive bindings, pagination (date range/page number), ViewModel, ViewController, Navigator, and tests for iOS reactive projects. Use when "create reactive list", "generate reactive list", "new reactive list screen", "create rxswift list", or "generate list with rxswift".

Expert prompt engineering for LLMs and AI agents. Use when users request help writing, reviewing, or improving prompts for chatbots, AI agents, system prompts, instruction sets, or any LLM-based application. Applies research-backed techniques to minimize hallucinations and maximize reliability.

Production-ready scripts for Android app testing, building, and automation. Provides semantic UI navigation, build automation, accessibility testing, and emulator lifecycle management. Optimized for AI agents with minimal token output. Android equivalent of ios-simulator-skill.

Test-Driven Development following Kent Beck's TDD and Tidy First principles. Use when implementing features with test-first approach, following Red-Green-Refactor cycle, or separating structural changes from behavioral changes in commits.

Use when orchestrator generates new stories or user says "vet stories", "check conflicts", "find duplicates", "scan for overlaps" - scans story-tree database to detect duplicate, overlapping, or competing stories. Returns conflict pairs with types and confidence scores for human review.

Generates a complete iOS app icon set with all required sizes. Use when asked to create an app icon, design an iOS icon, generate app store artwork, or make an icon for an iPhone/iPad app. Follows a philosophy-first approach - first defining the visual identity and concept, then producing production-ready icons.

Board game design workflow for creating fun, balanced games. Use when designing mechanics, balancing factions, analyzing resource economies, validating rules clarity, planning playtests, or iterating on game systems. Applies Eurogame principles and proven design methodology.

Apply rigorous scientific writing standards for academic manuscripts. Use when writing abstracts, introductions, methods, results, or discussions for papers, grants, theses, or mermaid figure.

Implements testing strategies for React Native components, MST stores, and services using Jest, React Testing Library, and Maestro. Use when writing unit, integration, or E2E tests in Purrsuit Mobile App.

Use this skill when Claude needs an outside perspective on complex problems, is stuck on a technical challenge, needs validation of an approach, or wants consultation on architectural decisions. Provides access to Codex and Gemini for getting unbiased second opinions and fresh perspectives.

Automatically applies when optimizing database queries. Ensures EXPLAIN analysis, proper indexing, N+1 prevention, query performance monitoring, and efficient SQL patterns.

Implement Electron desktop app patterns for PhotoVault bulk uploader. Use when working with main/renderer process communication, chunked uploads, preload scripts, protocol handlers, or auto-updater. Includes security patterns and memory management for large file uploads.

Master docker & container technology. Production-ready code examples, best practices, and real-world applications.

Create apps following contract-port architecture with composition roots. Use when creating new apps in apps/, scaffolding CLI tools, setting up dependency injection, or when the user asks about app structure, entrypoints, or platform-agnostic design.

PROACTIVELY convert approved OpenSpec specs into Beads issues when user applies a change or explicitly approves implementation. Creates trackable work with dependencies, discovers gaps, and maintains audit trail between planning and execution.

Adapter Layer 전문가. CommandAdapter(persist만, JpaRepository 1:1), QueryAdapter(4개 메서드, QueryDslRepository 1:1),AdminQueryAdapter(Join 허용, DTO Projection), LockQueryAdapter(6개 Lock 메서드).필드 2개만(Repository + Mapper). @Component 필수. @Transactional 절대 금지.
