TaxasGE Backend Dev

3-tier architecture separates routes (API layer), services (business logic), and repositories (data access). This Skill provides templates for each layer enforcing strict separation, dependency injection, validation, and error handling to keep your backend organized and maintainable without workflow disruption.

The Skill includes endpoint, service, and repository templates you can copy into your FastAPI project. Replace placeholders with your module names and domain models to scaffold new features consistently while maintaining the 3-tier pattern and RBAC rules.

RBAC implementation uses the Skill's architecture patterns and reference documentation in `.github/docs-internal/Documentations/Backend/`. Templates guide you through adding authorization checks at the route and service layers to enforce access rules.

Yes. The Skill acts as a technical reference and starter kit without forcing workflow changes. Adopt the 3-tier templates and patterns incrementally, aligning your existing code with the documented backend architecture.

Backend documentation is centralized at `.github/docs-internal/Documentations/Backend/` as a single source of truth. This prevents duplication and ensures all architecture decisions, RBAC patterns, and technical references stay aligned.

Dependency injection decouples layers by passing dependencies (services, repositories) into route handlers and services rather than hardcoding them. This supports testability, flexibility, and the strict 3-tier separation the Skill enforces.
