Expert senior-level Go guidance for architecture, API-first design/codegen, advanced concurrency, performance tuning, testing/quality, cloud-native 12-factor practices, and Go 1.24+ tooling for large-scale systems.
Strategic guidance for choosing and implementing testing approaches across the test pyramid. Use when building comprehensive test suites that balance unit, integration, E2E, and contract testing for optimal speed and confidence. Covers multi-language patterns (TypeScript, Python, Go, Rust) and modern best practices including property-based testing, test data management, and CI/CD integration.
Create detailed technical specifications, requirements documents, design documents, and system architecture specs. Use when writing technical specs, requirements docs, or design documents.
Modern TypeScript project architecture guide for 2025. Use when creating new TS projects, setting up configurations, or designing project structure. Covers tech stack selection, layered architecture, and best practices.
Comprehensive thoroughness framework. Auto-invoked when planning features, implementing code, fixing bugs, writing tests, analyzing existing code, auditing features, reviewing architecture, or investigating issues. Forces systematic consideration of all edge cases, failure modes, error scenarios, security implications, state transitions, and hidden assumptions so nothing gets missed. Do NOT invoke for trivial changes like typos, renames, single-line fixes, adding imports, or updating config values.
Detailed development workflow patterns, checklists, and standards. Auto-loads for complex tasks, planning, debugging, testing, or when explicit patterns are needed. Contains session protocols, git conventions, security checklists, testing strategy, and communication standards.
Transform approved requirements into comprehensive technical designs. Define system architecture, component interactions, data models, and interfaces to create a blueprint for implementation.
Core code quality principles for writing maintainable code. Use when reviewing code for design violations, assessing code quality, or applying architectural patterns like composition, immutability, and fail-fast.
Comprehensive testing specialization covering test strategy, automation, TDD methodology, test writing, and web app testing. Use when setting up test infrastructure, writing tests, implementing TDD workflows, analyzing coverage, integrating tests into CI/CD, or testing web applications with Playwright. Framework-agnostic approach with framework-specific guidance via reference files.
Analyze and create a testing strategy for native Android apps - install testing libraries, set up test infrastructure, create harnesses for unit tests, UI tests, screenshot tests, and end-to-end tests.
Construct a business cycle model using leading and coincident indicators, and interpret two business cycle phases: Expansion (Risk-On) and Contraction (Risk-Off), and generate "Iceberg" and "Sinking" event signals based on the theory.
Patrons et stratégies de test complets pour les projets JavaScript/TypeScript. Couvre les tests unitaires, d'intégration et E2E, les stratégies de mocking, l'organisation des tests et les anti-patrons courants. À utiliser quand l'utilisateur veut écrire des tests, améliorer la couverture de tests, établir une stratégie de test ou corriger des tests instables.
