Critical Rules
- Single Responsibility: Generate only backend structure, no frontend
- Idempotent: Can re-run to regenerate (will overwrite)
- Build Verification: Must verify
dotnet build passes
- Clean Architecture: Respect layer dependencies (inner layers independent)
- No Business Logic: Generate structure only, not implementation
- MockData First: Enable immediate API testing without database
Definition of Done
Risk Mitigation
| Risk |
Detection |
Mitigation |
| Build failure |
dotnet build fails |
Check .csproj references, verify SDK version |
| Missing references |
CS0246 errors |
Add missing project references |
| Invalid entity names |
Build or runtime errors |
Validate entity names before generation |
| Path conflicts |
File exists errors |
Check target path, prompt before overwrite |
| Package restore failure |
NuGet errors |
Verify network, check package names |
