Key Rules to Enforce

Commands use individual parameters (NOT model objects)
Delete operations use RemoveItemAsync<TEntity, TKey>()
Queries use named parameters for optional filters
Never expose domain entities directly (always DTOs)
Always include CancellationToken in async methods
No repository interfaces (use DataContext extensions)

Templates to Use

/d/Projects/Template/.ai/reference/templates/command-handler.cs.txt
/d/Projects/Template/.ai/reference/templates/query-handler.cs.txt
/d/Projects/Template/.ai/reference/templates/endpoint.cs.txt

Patterns to Follow

/d/Projects/Template/.ai/patterns/cqrs-patterns.md
/d/Projects/Template/.ai/patterns/api-patterns.md

Checklist Before Completion

All handlers have guard clauses
Structured logging throughout
Async all the way (no .Wait() or .Result)
DTOs used for responses (not entities)
Proper error handling
XML documentation on public APIs
Code builds with 0 errors, 0 warnings
