テストの書き方とTDDの実践ガイド

Reviews test coverage and suggests missing test cases for error paths, edge cases, and business logic. Activates when users write tests or implement new features.

Executa CodeRabbit CLI em modo prompt-only para revisar alterações locais, identificar issues, planejar correções e validar com testes antes do commit

Write strategic, behavior-focused tests for critical paths without over-testing during development. Use this skill when writing unit tests, integration tests, or end-to-end tests. When working on files in tests/, __tests__/, spec/, or any test files. When deciding what to test, naming test cases, or mocking external dependencies. When focusing on core user flows rather than edge cases during feature development.

Use when implementing features or refactoring with TDD - enforces writing ONE test at a time, implementing minimal code to pass, then repeating, preventing batch test writing that defeats incremental design discovery

Validate implementation against test cases and acceptance criteria. Use when checking if code works correctly, validating against user-provided test cases, or verifying acceptance criteria are met. Gets test cases from user input or previous workflow stages.

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".

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.

ALWAYS use this skill proactively for Consumer Affairs Django repositories (located in ../ca/ directory) when ANY of these occur - (1) After writing or modifying ANY Python code files in CA repos (2) After tests pass and before telling user work is complete (3) User mentions linting, formatting, ruff, code style, or code quality (4) After using the ca-django-tests skill successfully (5) Before preparing to commit code. This skill runs 'ca exec ruff format' and 'ca exec ruff check --fix' to ensure code quality. CRITICAL - Always run this automatically after code changes and before declaring work complete.

Work with this repo’s GitHub Actions CI and GHCR Docker image publishing workflow. Use when changing generation checks, tests, formatting, or when preparing a release and validating image tags.

Document REST API endpoints through systematic empirical testing. Analyzes URL structure, generates minimal test cases, executes requests, and produces concise API documentation. Use when exploring undocumented APIs, reverse-engineering endpoints, or creating integration documentation.

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 creating REST API clients, SDK wrappers, or HTTP service integrations. Generates type-safe client code with retry logic, error handling, rate limiting, and comprehensive tests. Triggered by requests to integrate external APIs, build SDK clients, or create service wrappers.

Develop features for the Cljr Clojure-to-.NET compiler. Use when adding emitter features, expression types, analyzer support, or testing features. Guides the complete workflow from Expr.cs to C# tests to NRepl verification. Critical for REPL-oriented development.

Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.

Expert UX evaluator for command-line interfaces, CLIs, terminal tools, shell scripts, and developer APIs. Use proactively when reviewing CLIs, testing command usability, evaluating error messages, assessing developer experience, checking API ergonomics, or analyzing terminal-based tools. Tests for discoverability, consistency, error handling, help systems, and accessibility.

Verwandelt den Agenten in einen professionellen MV3-Architekten und Entwickler mit Fokus auf AI-Integration, Sicherheit, Performance, Testing und Publishing-Compliance.

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.

Safely inject new code into legacy codebases with risk containment. Use for feature flags, gradual rollouts, A/B testing new logic, or refactoring critical paths. Implements try-catch fallbacks, feature toggle architecture, and surgical separation of old/new code.
