單元測試

Design optimal test pyramids with unit/integration/E2E ratios. Identify anti-patterns and recommend architecture-specific testing strategies.

Design consumer-driven contract testing strategies using Pact, verify provider contracts, and manage API evolution with contract-first approaches.

Creates CDP journey definitions in YAML using `tdx journey` commands. Covers journey stages, steps (wait, activation, decision_point, ab_test, merge, jump, end), entry/exit criteria, goals, embedded segments, and versioning. Use when building customer journey orchestration workflows or managing journey YAML files.

Plan prototyping approach - fidelity levels, tool selection, prototype types, testing strategies, and design-to-development handoff.

Write high-quality Rust unit tests following best practices. Use when writing new tests, reviewing test code, or improving test quality. Emphasizes clear naming, AAA pattern, isolation, and deployment confidence.

Create comprehensive test strategy documents following IEEE 829 structure. Plan test approach, scope, resources, and success criteria for software projects.

ALWAYS invoke FIRST on ANY "build/create/implement/add feature" request. This skill WRAPS brainstorming - it decides the approach. Present choice BEFORE any brainstorming starts: (1) Brainstorm together step-by-step, OR (2) Omakase - I generate 3-5 best approaches, implement in parallel, tests pick winner. If user picks brainstorming, check if brainstorming skill exists - if yes use it, if no do brainstorming yourself (ask questions, propose options, validate). Also triggers DURING brainstorming on 2+ "not sure"/"don't know" responses. For same design competing implementations, use cookoff.

Complete guide to Japanese Language Proficiency Test preparation with strategies for vocabulary, kanji, grammar, reading, and listening across all levels

Python development standards and toolchain preferences. Use when (1) writing ANY Python code, (2) setting up Python projects with pyproject.toml, (3) creating standalone CLI scripts, (4) configuring Python tooling (ruff, mypy, pytest, nox, uv), (5) reviewing or refactoring Python code, or (6) advising on Python best practices. Enforces modern Pythonic style, strict type hints, and uv-based workflows.

TDD with RGRC cycle and Baby Steps methodology. Triggers: TDD, テスト駆動開発, Red-Green-Refactor, Baby Steps, test generation, テスト生成, テスト設計, テストケース, boundary value, 境界値分析, coverage, カバレッジ, unit test

Provides React component development standards and best practices. Ensures component quality through proper hooks usage, state management patterns, and performance optimization techniques. Specializes in functional components, custom hooks, context API, memoization strategies, and accessibility compliance.Use when: developing React components (.jsx/.tsx files), creating custom hooks, implementing state management with useState/useReducer/useContext, optimizing performance with useMemo/useCallback/React.memo, handling side effects with useEffect, designing component props and interfaces, implementing conditional rendering patterns, testing with React Testing Library, or integrating with TypeScript for type-safe components.

Comprehensive Solidity smart contract development skill using Foundry framework. Use for writing, testing, deploying, and auditing Solidity contracts with security-first practices. Also triggers when working with .sol files, Foundry project files (foundry.toml), test files (.t.sol), or smart contract deployment scripts. Example triggers: "Write smart contract", "Create Solidity test", "Deploy contract", "Audit smart contract", "Fix security vulnerability", "Write Foundry test", "Set up Foundry project"

Design, test, and version prompts with systematic evaluation and optimization strategies.

Review Python code for adherence to SOLID principles (SRP, OCP, LSP, ISP, DIP). Use when reviewing Python code for maintainability, testability, and design quality.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Use this skill when building, testing, or working with Docker images in the agentic-container repository. Covers when to rebuild vs reuse images, how to leverage layer caching, and efficient iteration patterns.

Use when investigating bugs that need reproduction - covers local HA/Emby testing, evidence gathering, root cause analysis, and updating issues with findings and fix recommendations.

Test-Driven Development facilitation using the red-green-refactor cycle. Guides users throughwriting tests first, implementing minimal code to pass, and refactoring for quality. Use whenusers want to practice TDD, need help writing tests before code, are developing new featurestest-first, or want guidance on test structure and implementation. Triggers include 'use TDD,''test-driven development,' 'write tests first,' 'red-green-refactor,' or requests to developfunctionality with tests.

Generate realistic clinical trial synthetic data including study definitions, sites, subjects, visits, adverse events, efficacy assessments, and disposition. Use when user requests: clinical trial data, CDISC/SDTM/ADaM datasets, trial scenarios (Phase I/II/III/IV), FDA submission test data, or specific therapeutic areas like oncology or biologics/CGT.
