This Claude Skill automates ML experiment tracking setup for tools like MLflow or Weights & Biases when triggered by requests to initialize tracking. It configures the environment, sets up tracking servers when needed, and provides ready-to-use code snippets for logging parameters, metrics, and artifacts. Use this skill to ensure reproducibility and simplify model run comparisons in your ML projects.

This skill enables Claude to orchestrate multi-agent systems using the AI SDK v5, allowing developers to create coordinated workflows with agent handoffs and intelligent routing. It supports multiple AI providers like OpenAI, Anthropic, and Google for building complex multi-agent applications. Use this when you need to coordinate specialized agents, manage task routing, or implement sophisticated agent collaboration systems.

This skill enables Claude to automatically validate AI/ML models and datasets for ethical concerns and potential biases. It triggers when users request fairness assessments, bias detection, or ethics reviews using related keywords. The skill analyzes systems and provides mitigation recommendations to support responsible AI development.

This skill enables Claude to execute visual regression tests using tools like Percy and Chromatic to capture screenshots and compare them against baselines. It automatically identifies unintended UI changes by analyzing visual differences in web applications or components. Use it when you need to verify UI changes, perform regression testing, or check for visual inconsistencies.

This skill automatically generates comprehensive unit tests from source code when developers request test creation. It supports multiple testing frameworks like Jest, pytest, and JUnit, intelligently detecting the appropriate one or using a specified framework. Use it when asking to "generate tests," "create unit tests," or using the "gut" shortcut with file paths.

This skill generates comprehensive test reports by aggregating results from multiple testing frameworks and calculating key metrics like coverage and pass rates. It provides trend analysis and outputs reports in developer and stakeholder-friendly formats including HTML, PDF, and JSON. Use it when you need to create test reports, analyze failures, or compare historical test data.

This skill enables Claude to orchestrate complex test workflows using a dedicated plugin. It allows defining test execution graphs with dependencies, running tests in parallel, and intelligently selecting tests based on code changes. Use it for managing test orchestration, dependency management, parallel execution, and smart test selection in CI/CD pipelines.

This skill enables Claude to create and manage isolated, reproducible test environments using Docker Compose and Testcontainers. It helps developers set up test infrastructure, configure environment variables, and ensure proper cleanup. Use this skill when you need to automate test environment setup for consistent software testing.

This Claude skill automatically generates test doubles like mocks, stubs, spies, and fakes for unit testing. It analyzes code dependencies and creates appropriate doubles for frameworks such as Jest or Sinon. Use it when you need to isolate code units for testing by triggering with `/gen-doubles` or a direct request.

This Claude skill generates realistic test data like users, products, and orders for software development. It's ideal for populating databases, creating test fixtures, or simulating user behavior in testing environments. Developers can trigger it with phrases like "generate test data" or "create fake users" to quickly produce sample data.

This skill analyzes code coverage metrics to identify untested code and generate comprehensive coverage reports. It helps developers improve code quality by pinpointing gaps in test suites and ensuring adequate test coverage. Use trigger terms like "analyze coverage," "code coverage report," or "cov" to activate it.

This skill helps developers manage snapshot tests by analyzing failures and selectively updating snapshots to distinguish intentional changes from regressions. It's triggered when users mention snapshot tests, failures, or request updates using commands like "/snapshot-manager". The skill supports popular testing frameworks including Jest, Vitest, Playwright, and Storybook.

This skill runs smoke tests to verify critical application functionality through pre-defined test suites. It checks system health, authentication, core features, and external integrations to ensure operational status. Use it after deployments, upgrades, or significant configuration changes by triggering with "smoke test" or "st".

This skill automates security vulnerability testing for applications and APIs when triggered by terms like "security test" or "OWASP." It performs scans for common threats including the OWASP Top 10, SQL injection, XSS, and CSRF. Use it to generate comprehensive security assessment reports on demand.

This skill enables Claude to track and run regression tests to ensure new code changes don't break existing functionality. It helps maintain code stability by identifying critical tests, automating their execution, and analyzing the impact of changes. Use it when you need to run regression tests or track test history using the "reg" shortcut.

This skill enables Claude to automate performance testing by designing and executing load, stress, spike, and endurance tests. It analyzes key metrics like response time and throughput to identify bottlenecks in CPU, memory, database, or network. The skill then provides comprehensive reports with graphs and optimization recommendations.
