AI Agent for App Clone Backend: Auth, Payments & More

This AI agent skill constructs the backend infrastructure for app clones, providing features such as authentication, database migrations, payment processing with Stripe, email communication, background jobs, and third-party integrations using official APIs. Additionally, it maintains a security checklist to ensure best practices are followed.

What this skill does

• Implements authentication protocols, including email sign-up with verification, password reset, magic link functionality, and OAuth integration with Google and Apple.
• Handles database migrations and establishes access rules by interpreting the specification in `replica/architecture.md`.
• Integrates Stripe for payment processing, ensuring setups start with test modes.
• Facilitates email sending using user-provided service accounts.
• Manages background jobs and connects with third-party services via official APIs, requiring users to provide necessary authentication keys.
• Updates the `replica/backend.md` document regularly as part of the development process.
• Maintains secure session management through http-only secure cookies and allows account deletion policies.
