Skill UI

Test Data Builder Guidance auto-activates when you ask about test data strategies, best practices, or configuration for automation frameworks, delivering step-by-step patterns, production-ready samples, and validation against common standards.

Guides developers through strict test-driven development: write failing tests first, iterate red-green-refactor, and keep tests passing before refactoring to ensure reliable features.

This skill provides a systematic, multi-step approach to identify and resolve all failing unit tests within a codebase. It guides the user through smart error grouping (e.g., grouping by ImportError or AttributeError), prioritizing fixes from infrastructure to business logic, and ensuring thorough verification to prevent regressions. Ideal for use after major refactoring, debugging CI/CD failures, or when explicitly tasked with making the test suite pass.

A specialized skill designed to ensure robust software quality by covering the entire testing lifecycle. This includes defining test strategies, writing unit, integration, and E2E tests, and implementing advanced testing types like performance (k6), security (OWASP), and functional testing. It guides users through coverage analysis, debugging flaky tests, and generating detailed defect and quality reports.

Auto-activating guidance for enforcing test naming conventions across unit, integration, and mocking workflows in test automation projects, ensuring standards and generating ready-to-run code.

Auto-activating skill that organizes test automation work, offering step-by-step best practices for unit, integration, mocking, and framework setups whenever you mention “test organization helper.”

Automates help with test parallelizer workflows, offering guided best practices, configuration tips, and code snippets for parallelized unit and integration testing scenarios.

Automates guidance for configuring test retries in automation suites, walking through setup, best practices, and frameworks such as Jest or pytest so teams can stabilize flaky runs.

Validates Claude Code plugin activation by reading files, executing commands, and ensuring trigger phrases and tool permissions work as expected during E2E testing scenarios.

This skill validates web applications across diverse browsers (Chromium, Gecko, WebKit) and real mobile devices. It supports both local testing using Playwright and scalable cloud testing via major platforms like BrowserStack, Sauce Labs, and Kobiton. Use it when ensuring consistent UI/UX, correct CSS rendering, and functional JavaScript behavior regardless of the target environment or device type.

Meta-skill that analyzes the Trail of Bits Testing Handbook and generates Claude Code skills for security testing tools and techniques, ideal for creating or refreshing handbook-based skills in bulk.

This skill enables Claude to run the load-balancer-tester plugin and validate traffic distribution, failover handling, sticky sessions, and health check behavior so teams can ensure high availability before deployment.
