How does it handle database changes?

The skill follows a 'migrations-first' workflow, ensuring that schema changes are defined, reviewed, and applied before any feature code is written, maintaining data integrity.

Is security built into the code generation?

Yes, security is a core principle. The skill implements input validation, parameterized queries, and follows the security ownership assigned in the technical architecture.

What frameworks does this skill support?

While the provided patterns highlight FastAPI and SQLAlchemy, the logic is based on universal backend principles like layered architecture and specification-driven development that can be adapted to various modern stacks.

Does it include automated testing?

Absolutely. It generates implementation-ready unit tests for complex logic and integration tests for API endpoints to ensure the backend meets performance and reliability targets.
