 ### Step 2: Create Service Layer

 ## Key Patterns
 
-1. **Services are pure, interfaces are thin adapters.** The service contains all business logic. The server action (or
-   MCP tool, or CLI command) is glue code that resolves dependencies and calls the service. If an MCP tool and a server
-   action do the same thing, they call the same service function.
-2. **Inject dependencies, don't import them in services.** Services receive their database client, logger, or any I/O
-   capability as constructor arguments — never by importing framework-specific modules. This keeps them testable with
-   stubs and reusable across interfaces.

 3. **Schema in separate file** - Reusable between client and server
 4. **Logging** - Always log before and after operations
 5. **Revalidation** - Use `revalidatePath` after mutations
 6. **Trust RLS** - Don't add manual auth checks (RLS handles it)
-7. **Testable in isolation** - Because services accept their dependencies, you can test them with a mock client and no
-   running infrastructure
