Testing skills

This skill reviews code for best practices, bugs, security, and performance, delivering actionable feedback to improve quality.

This skill helps you validate basic skill structures and ensure compatibility across discovery, parsing, and integration workflows.

This skill helps test argument substitution patterns within prompts by analyzing placeholders like $ARGUMENTS and ensuring literal escapes.

This skill helps you test lazy loading and performance with a large content dataset to evaluate loading strategies and resilience.

This skill validates a version field in a skill, enabling reliable version parsing and testing for agents.

This skill validates Unicode handling in prompts and responses, ensuring emojis and multilingual content are parsed and preserved.

This skill helps validate and safely handle inputs with special characters to prevent injections and unintended command execution.

This skill helps identify security vulnerabilities in Java code and suggests secure coding practices to reduce risk.

This skill generates Spring Boot components following modern Java best practices and team conventions to ensure clean, scalable code.

This skill helps you build robust terminal UIs with OpenTUI, guiding framework selection, components, layout, input, and testing practices.

This skill helps implement secure email and password authentication with verification, resets, and token protection using Better Auth.

This skill helps you apply property-based testing to validate serialization, normalization, and pure functions by asserting key invariants across inputs.

This skill provides a systematic Playwright debugging workflow to diagnose flaky tests, timeouts, and element interactability issues quickly.

This skill helps you verify skills under pressure using RED-GREEN-REFACTOR, documenting failures and iterating to close loopholes.

This skill guides you through test-driven development, ensuring you write a failing test first and implement minimal code to pass.

This skill helps you write robust tests by emphasizing integration over unit tests, waiting for real conditions, and using strategic mocks.

This skill helps you write robust Playwright automation by applying best practices for selector strategies, waiting patterns, and flaky test reduction.

This skill enforces Functional Core and Imperative Shell separation in new or refactored Python code, ensuring pure logic remains separate from I/O.

This skill helps you write and refactor code effectively by enforcing functional vs imperative separation and defensive data validation.

This skill helps you implement Stripe payments and subscriptions in Next.js projects, including checkout, webhooks, and customer management.

This skill guides Rust developers through error handling, testing, and logging patterns, demonstrated via includes composition and practical CLI examples.
