Integration with the Pest PHP testing framework for writing and running tests

Specialized skill for Rails testing with RSpec, FactoryBot, and TDD workflows. Use when writing tests, setting up test coverage, creating factories, or implementing test-driven development. Covers unit tests, integration tests, system tests, and component tests.

REST API specialist for Rails applications. Use when building API endpoints, implementing serialization, API versioning, JWT authentication, or creating API documentation. Focuses on RESTful design, performance, and consistency.

Effectively use Narwhals to write dataframe-agnostic code that works seamlessly across multiple Python dataframe libraries. Write correct type annotations for code using Narwhals.

Implements approved specification proposals by working through tasks sequentially with testing and validation. Use when implementing changes, applying proposals, executing spec tasks, or building from approved plans. Triggers include "implement", "apply change", "execute spec", "work through tasks", "build feature", "start implementation".

Execute specification-driven implementation with automatic quality gates, multi-agent orchestration, and progress tracking. Use when building features from specs, fixing bugs with test coverage, or refactoring with validation.

Write effective TableTest-style tests for data-driven testing in JUnit using either Java or Kotlin. The table format makes tests more readable, maintainable, and collaborative - treating test data as first-class documentation of system behaviour. Use it when testing the same logic with multiple input/output combinations, when you have 2+ similar test methods differing only in data values, when business rules involve multiple cases/examples, or when adding new test cases should be as simple as adding a table row. Use standard JUnit @Test when testing a single scenario, when test logic differs significantly between cases, when complex setup/teardown varies per test, or when mocking behaviour differs per test case.

Systematically debug issues with reproduction steps, error analysis, hypothesis testing, and root cause fixes. Use when investigating bugs, analyzing production incidents, or troubleshooting unexpected behavior.

Automated workflow for running tests and fixing failures systematically. Use when implementing the mandatory test workflow or fixing code quality issues. Keywords - testing, debugging, workflow, failures, systematic fixes.

Writes, reviews, and refactors Python code following modern best practices. Specialises in Python 3.12+, uv for project management, type hints, polars over pandas, pydantic for validation, and pytest for testing. Use when working with Python code.

Mandatory code quality workflow that must run after ANY code changes. Use after creating/editing files, before commits, or when fixing errors. Keywords - testing, linting, formatting, typecheck, quality gates, workflow.

Project management skill that analyzes tasks, breaks them down into stages, coordinates other skills, and ensures proper workflow. Use when planning features, managing complex multi-step implementations, or need help organizing development tasks. Routes work to specialized skills (testing, security, components, etc.).

Guide for building and maintaining ActivityPub/fediverse applications using Fedify. This skill should be used when users want to create federated social applications, implement ActivityPub protocols, build new features, test and debug federation, deploy to production, look up FEPs, or maintain existing Fedify applications.

Comprehensive testing patterns for React components with MSW, React Query, and Vitest. Use when writing tests, setting up mocks, testing API interactions, or ensuring 80% coverage. Keywords - testing, MSW, React Query, Vitest, mocks, coverage, API testing.

Specialized skill for Rails security, authorization, and data protection. Use when implementing Pundit policies, Lockbox encryption, Blind Index searches, authentication, secure configuration, or fixing security vulnerabilities. Includes security best practices and common pitfall prevention.

Expert frontend web development including HTML/CSS/JavaScript implementation, responsive design, accessibility improvements, and Playwright browser automation testing. Balances modern frameworks with pragmatic vanilla solutions. Use when working with web frontends.

Provides expertise on how to write effective unit tests (runtime and type tests), make testing decisions, and incorporate TDD into development workflows

Use Hypothesis for property-based testing to automatically generate comprehensive test cases, find edge cases, and write more robust tests with minimal example shrinking. Includes Polars parametric testing integration.

Comprehensive Salesforce testing skill with test execution, code coverage analysis, and agentic test-fix loops. Run Apex tests, analyze coverage, generate test patterns, and automatically fix failing tests with 120-point scoring.

Comprehensive Playwright end-to-end testing expertise covering browser automation, cross-browser testing, visual regression, API testing, mobile emulation, accessibility testing, test architecture, page object models, fixtures, parallel execution, CI/CD integration, debugging strategies, and production-grade E2E test patterns. Activates for playwright, e2e testing, end-to-end testing, browser automation, cross-browser testing, visual testing, screenshot testing, API testing, mobile testing, accessibility testing, test fixtures, page object model, POM, test architecture, parallel testing, playwright config, trace viewer, codegen, test debugging, flaky tests, CI integration, playwright best practices.
