Frequently Asked Questions About AJ
FAQPage SchemaWhat tasks can I accomplish using AJ's skills?▼
You can write and debug Playwright E2E, component, accessibility, and security tests; generate OpenAPI 3.1 specifications; optimize PostgreSQL queries; apply React/Next.js performance patterns; build advanced TypeScript type utilities; run threat models; and follow TDD, systematic debugging, and verification-before-completion disciplines.
Who are these skills designed for?▼
Software engineers, QA engineers, and AppSec practitioners working on web applications. They target developers writing Playwright or WordPress/PHPUnit tests, TypeScript and React/Next.js code, PostgreSQL-backed services, and security reviewers performing threat modeling or language-specific security reviews for Python, JavaScript/TypeScript, and Go.
How do the testing and quality skills work in practice?▼
The Playwright skill guides test authoring, flaky-test fixes, mocking, authentication, and CI/CD configuration. The TDD skill enforces red-green-refactor, systematic-debugging structures bug investigation, and verification-before-completion requires running verification commands and confirming output before claiming work is done.
Are these skills open source and what do they cost?▼
The skills are free to use. Playwright-best-practices, postgres, and vercel-react-best-practices carry explicit MIT licenses from currents.dev, PlanetScale, and Vercel respectively; the remaining skills ship without stated license fees or commercial restrictions in their manifests.
What prerequisites or dependencies do these skills require?▼
Prerequisites match each domain: a Playwright setup for browser testing, a PostgreSQL database for query optimization, TypeScript and React/Next.js projects for the language and performance skills, a codebase or path for threat modeling, and WordPress with PHPUnit for the wp-test-strategy guidance.
