Find the perfect capability for your agent.
Pytest test development for Python microservices. Use when writing unit tests, integration tests, fixtures, mocking external services, or setting up test infrastructure.

Chrome DevTools MCP for browser automation. Five servers configured for parallel agents. Auto-select available server, cleanup when done.
ALWAYS use this skill proactively for Consumer Affairs Django repositories (located in ../ca/ directory) when ANY of these occur - (1) User mentions coverage, codecov, test coverage, partial coverage, branch coverage, or uncovered lines/code (2) User asks to write tests, add tests, run tests, or fix test failures (3) User asks to implement features, fix bugs, or modify code in CA repos and tests are needed (4) User provides a file path containing 'test' or 'tests' in CA repos (5) After writing new code in CA repos that needs test coverage. This skill handles Django test execution using the 'ca magictest' command and ensures 100% code coverage for CI requirements.
Test-driven development. Use when asked to use TDD explicitly, or any other times when asked write a failing test before implementation, or similar.
test-engineer skill Trigger terms: testing, unit tests, integration tests, E2E tests, test cases, test coverage, test automation, test plan, test design, TDD, test-first Use when: User requests involve test engineer tasks.
Generates Playwright tests that detect iOS/mobile UX anti-patterns in CI. Use this when the user wants to add automated UX pattern checks for web apps targeting mobile/iOS. Creates tests that FAIL when hamburger menus, FABs, small touch targets, or other anti-patterns are detected.
Strategy and patterns for designing and implementing End-to-End scenario tests using the Python SDK. Focuses on full-stack verification and SDK usability.
Create end-to-end tests for React applications using Playwright. Use when writing E2E tests, testing user journeys, or setting up Playwright.
Unit testing patterns with Vitest. Use when writing tests for TypeScript code.
Implement authentication testing patterns with RSpec, FactoryBot, and test helpers for Rails applications. Use when writing controller specs, system tests, or request specs that require authenticated users and multi-tenant account context.
Guide for using Assert class (webmozart/assert) for data validation and type enforcement. Use when adding validation to value objects or domain methods.
Develop, test, and maintain the Paracle framework codebase. Use when implementing features, fixing bugs, writing tests, or refactoring framework code.
Implements features from technical specifications using TDD. Use when: repo contains /docs/specs/*.md, task references acceptance criteria (AC-*), .claude/current_task.json exists, or user mentions "implement the spec", "work on AC-", or "test first".
Write or extend Kyora backend E2E tests using the existing container-based harness, helpers, and HTTP client patterns. Use when adding/changing backend behavior.
Debugs failing tests, flaky tests, and Node processes that won't exit after tests complete. Use when backend/shared/frontend tests fail or hang.
Develop, test, and maintain the Paracle framework codebase. Use when implementing features, fixing bugs, writing tests, or refactoring framework code.
Run Vitest tests for the Babylon.js game project. Use when the user wants to run tests, check test coverage, debug failing tests, or validate code functionality.
PHP 8.4+ best practices with PHPUnit 11, Composer, PSR-12 standards,
Strict test-driven development state machine with red-green-refactor cycles. Enforces test-first development, meaningful failures, minimum implementations, and full verification. Activates when user requests: 'use a TDD approach', 'start TDD', 'test-drive this'.
Build comprehensive test suites for FastAPI applications using pytest and pytest-asyncio. This skill should be used when users want to write unit tests, integration tests, or end-to-end tests for FastAPI endpoints, async functions, database operations, and business logic. Covers test organization, fixtures, mocking, async testing, and CI/CD integration. Always fetches latest pytest and pytest-asyncio documentation before implementation.
