Testing & QA Agent Skills

Create new skills, modify existing ones, and measure their performance through iterative evaluation and benchmarking.

Execute the full AgentHub competition lifecycle in a single command: initialize, capture baseline, spawn agents, evaluate results, and merge the winner.

Validates, tests, and scores the quality of skills within a claude-skills ecosystem using Python scripts that check structure, syntax, runtime, and multi-dimensional quality metrics.

Generates unit tests, integration tests, and E2E tests for React/Next.js applications by scanning components, analyzing coverage reports, and scaffolding Playwright test files.

Generates unit tests, analyzes coverage gaps, and guides red-green-refactor workflows across Jest, Pytest, JUnit, Vitest, and Mocha.

Designs and implements backend systems including REST APIs, microservices, database architectures, authentication flows, and security hardening. Covers Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.

Scaffold Next.js/React projects, generate components, analyze bundle sizes, and apply React/Next.js optimization patterns.

Systematically profile Node.js, Python, and Go applications to identify CPU, memory, and I/O bottlenecks, generate flamegraphs, analyze bundle sizes, optimize database queries, and run load tests with k6 and Artillery.

Enforce writing specifications before any code, with structured formats, acceptance criteria, and validation to reduce rework and clarify requirements.

Generate, review, fix, and migrate Playwright end-to-end tests with templates, CI integration, and optional TestRail/BrowserStack sync.

Scans API route definitions across frameworks (Next.js, Express, FastAPI, Django REST) and auto-generates comprehensive test suites covering auth, input validation, error codes, pagination, file uploads, and rate limiting.

Execute implementation plans by dispatching a fresh subagent per task, with task review after each and a whole-branch review at the end.

Sets up JavaScript/TypeScript projects with opinionated tooling and conventions including ESLint, TypeScript config, testing with Vitest, and monorepo setup.

Write and run unit tests with Vitest, a Vite-native testing framework offering Jest-compatible API, mocking, coverage, and snapshot testing.

Create, run, and analyze evaluation suites for Microsoft 365 Copilot declarative agents using the @microsoft/m365-copilot-eval CLI.

Guides testing Megatron-LM: test layout, recipe YAML, adding and running unit/functional tests, golden values, marker filters, and CI parity.

Modify, build, test, debug, and contribute to the NVIDIA cuOpt codebase (C++/CUDA, Python, server, CI). Includes guidance for solver internals, pull requests, DCO signoff, and code conventions.

Add a new cuTile GPU kernel operator to TileGym, covering dispatch registration, backend implementation, exports, tests, and benchmarks.

Provides best practices, patterns, and solutions for testing Vue.js applications, covering Vitest, Vue Test Utils, component testing, mocking, and Playwright for E2E testing.

Create comprehensive test scenarios from user stories with test objectives, starting conditions, user roles, step-by-step actions, and expected outcomes.

Runs adversarial UI tests in a real browser using the browse CLI, analyzing git diffs to test only changed areas or exploring the full app to find bugs in functionality, accessibility, responsive layout, and UX.

Automates visual testing and UI interaction verification using browser automation after deploying features.

Test-drive Django applications with pytest, factory_boy, and Django REST Framework, covering models, views, serializers, and API endpoints.

Write, fix, and run C++ tests using GoogleTest/GoogleMock with CMake/CTest, including TDD workflows, coverage, and sanitizers.

Write test-driven Laravel applications using PHPUnit, Pest, model factories, HTTP tests, Sanctum authentication testing, mocking, and coverage.

Test-driven development for Quarkus 3.x LTS using JUnit 5, Mockito, REST Assured, Camel testing, and JaCoCo. Use when adding features, fixing bugs, or refactoring event-driven services.

Provides a formal evaluation framework for Claude Code sessions, implementing eval-driven development (EDD) principles to define pass/fail criteria, measure reliability with pass@k metrics, and create regression test suites.

Provides comprehensive testing patterns for Perl applications using Test2::V0, Test::More, prove runner, mocking, and coverage analysis with Devel::Cover.

Uses two independent review agents to verify output quality, requiring both to pass before shipping.

Enforces test-driven development with 80%+ coverage including unit, integration, and E2E tests for new features, bug fixes, or refactoring.

Provides Vue.js 3 Composition API patterns, component architecture, reactivity best practices, Pinia state management, Vue Router navigation, and Nuxt SSR patterns for Vue, Nuxt, Vite, or Pinia projects.

Configure Celery with Django for background task processing, including task design, scheduling, retries, canvas workflows, monitoring, and testing.

Defines a gated Research-Plan-TDD-Review-Commit pipeline for orchestrating feature development, defect fixes, and refactoring tasks through composable phases and human approval gates.

Write behavior-focused React component tests with React Testing Library, Vitest/Jest, MSW for network mocking, and accessibility assertions using axe, while deciding when to use component tests versus Playwright/Cypress end-to-end tests.

Provides C# and .NET testing patterns using xUnit, FluentAssertions, mocking, integration tests, and test organization best practices.

Write and organize F# tests using xUnit, FsUnit, Unquote, FsCheck for property-based testing, and integration test patterns with ASP.NET Core and Testcontainers.
