Generate basic happy-path tests for Lorcana card abilities. Tests verify ability behavior only - NO property validation tests. Use when implementing or updating card tests. Effects are tested separately in the engine.
Use this skill when you need to compile CPython, run tests, verify your changes work, check if a fix is correct, or debug test failures. Covers building from source with ./configure and make, ccache for faster rebuilds, Argument Clinic regeneration, and the unittest-based test system (NOT pytest). Essential for any task that requires running code or tests.
Use this skill to verify work matches requirements. Activates when checking against specifications, validating acceptance criteria, or ensuring implementation matches design.
Applies TDD workflow to development. Use when implementing features, fixing bugs, or refactoring with test-first approach. Detects AI anti-patterns.
Handles all Golang testing tasks including running tests, writing new tests, and fixing test failures. Follows MCPSpy testing conventions with require for critical assertions and assert for non-critical ones.
Complete browser automation with Playwright. **ALWAYS use when user needs browser testing, E2E testing, screenshots, form testing, or responsive design validation.** Auto-detects dev servers, saves test scripts to working directory. Examples - "test this page", "take screenshots of responsive design", "test login flow", "check for broken links", "validate form submission".
Writes behavior specifications in Gherkin format. Use when defining features from user perspective or creating acceptance tests.
Cypress end-to-end testing guidance for opal-frontend, including Cucumber feature layout, tags, step definitions, Actions or Flows, selectors, and accessibility specs. Use when adding or updating E2E scenarios.
Test planning, writing, and review across unit/integration/e2e, primarily with pytest. Use when adding tests, improving coverage, diagnosing flaky tests, or designing a testing strategy.
Cypress component testing guidance for opal-frontend. Use when adding or updating component specs, configuring component test setup, or choosing selectors, mocks, and POM Actions or Flows.
Comprehensive testing strategies and coverage standards. Use when testing strategy guidance is required.
Use when user asks about E2E testing, performance testing, chaos engineering, test automation, flaky tests, test data management, or quality practices - routes to specialist reference sheets with deep expertise instead of providing general guidance
Implement security best practices for web applications and infrastructure. Use when securing APIs, preventing common vulnerabilities, or implementing security policies. Handles HTTPS, CORS, XSS, SQL Injection, CSRF, rate limiting, and OWASP Top 10.
