Validate Backend Patterns

Run comprehensive validation of the FastAPI backend to check for pattern violations.

Instructions

Run the validation script on the backend codebase:

python3 .claude-plugins/fastapi-patterns/scripts/validate_all.py --path src/backend --verbose

After running, analyze the output and:

1. For ERRORS: These MUST be fixed. They represent violations of critical patterns that will cause issues.

2. For WARNINGS: These SHOULD be fixed when possible. They indicate potential issues or non-standard patterns.

3. For INFO: These are suggestions for improvement but not critical.

What Gets Validated

• Schemas: Must inherit from CamelModel, not BaseModel directly
• Routers: Should use proper dependency injection for sessions
• Services: Should not store sessions, should use domain exceptions
• Repositories: Should use async methods and flush() instead of commit()
• Models: Should use Mapped type hints with mapped_column()
