Data splitting for model validation using TD_TrainTestSplit

Manages testing lifecycle including unit tests, integration tests, validation, and quality assurance.

Define the holistic testing approach across functional, non-functional, and automation layers for the initiative.

Proactively audits developer work to ensure completeness and production-readiness. This skill should be used when reviewing code changes, validating task completion, or verifying that work meets industry standards—catching incomplete implementations, deferred features, hardcoded values, missing tests, and shortcuts before code goes to production.

Master testing strategies (unit, integration, E2E), security best practices, OWASP Top 10, secure coding, and system monitoring. Learn to write secure code, comprehensive tests, and build resilient systems with proper incident response and compliance.

Create dbt models following FF Analytics Kimball patterns and 2×2 stat model. This skill should be used when creating staging models, core facts/dimensions, or analytical marts. Guides through model creation with proper grain, tests, External Parquet configuration, and per-model YAML documentation using dbt 1.10+ syntax.

Goバックエンドのビルド・テスト・Lintワークフロー。「Goビルド」「バックエンドテスト」「golangci-lint」「go mod」「go test」「swagger」などのキーワードで自動適用。

TypeScript monorepo patterns including contract-port architecture, dependency injection, hermetic primitive ports, and composition root. Use when creating packages, designing contracts/interfaces, implementing ports, wrapping platform primitives (Date, console, process), or testing with inline mocks.

Run Java/Spring Boot tests and debug failures. Use when fixing backend tests, implementing new features with tests, or debugging test failures.

Validates code quality before commits in the MigraineTracker React Native project. Use this skill when preparing to commit code, before pushing changes, or when the user asks to run pre-commit checks. Ensures TypeScript type safety, test coverage (80%+), passing tests, and proper branch strategy compliance.

Write tests following 3-layer pyramid (unit 95%, integration 85%, E2E critical paths) with 1:1 file mapping for unit tests. Covers test organization, coverage requirements, fixtures, and best practices. Use when writing tests, checking coverage, or validating test structure.

Testing StickerNest widgets and components. Use when the user asks to test widgets, write tests, add tests, create test cases, run tests, debug tests, or verify widget functionality. Covers Playwright E2E tests, Vitest unit tests, widget integration testing, and pipeline testing.

Execute E2E tests for the account service with proper server setup, test execution, and cleanup. Use when user requests account E2E testing, test execution, or running Playwright tests for account features.

Use when implementing new features in Quetrex. Ensures TDD, TypeScript strict mode, Next.js App Router patterns, ShadCN UI components, and security best practices are followed. Updated for November 2025 standards.

Skill cho việc design, implement, và maintain tests hiệu quả.

Use Astro's modern web development stack including TypeScript, Tailwind CSS, Content Collections, islands architecture, and performance-first deployment practices. Use this skill when selecting technologies, configuring integrations, choosing deployment platforms, or making architectural decisions about the tech stack. When working on Astro configuration and integrations setup, choosing between SSG/hybrid/SSR rendering modes, selecting UI frameworks for interactive islands (React, Vue, Svelte), configuring Tailwind CSS or styling solutions, setting up Content Collections for type-safe content, choosing deployment adapters (Vercel, Netlify, Cloudflare), configuring testing tools (Vitest, Playwright), implementing performance optimization strategies, or adding third-party integrations and plugins.

Connect wallet to Web3 DApp - navigate to DApp, click Connect Wallet, approve in MetaMask popup, verify connection. Can be used as a test case or as a precondition for other tests.

Use when segmenting time-series into regimes, detecting structural breaks, or constructing context sets for few-shot learning. Covers GP-CPD algorithms, Matérn kernels, likelihood ratio tests, regime identification, market state transitions, volatility regime changes, and trend reversals in financial markets.

Guide developers through mutation testing to assess and improve test suite quality
