Service bypasses repository layer

Flags application services that directly reach persistence APIs where a repository boundary is expected.

warningviolationNo auto-fix

How to fix

  1. Move the query into the owning repository.
  2. Expose a narrow repository method for the service workflow.
  3. Keep tenant and transaction handling consistent with adjacent repository methods.

What it means

A service appears to bypass the repository/data-access abstraction for its module.

Why it matters

Bypassing repositories scatters persistence behavior and makes transaction, tenant, and query policies harder to enforce.

Common causes

  • A service imports the ORM client directly.
  • A quick query was added during feature work.
  • The repository does not yet expose the needed method.

Example bad pattern

BillingService calls prisma.invoice.findMany(...) directly while billing has an InvoiceRepository.

Example good pattern

BillingService calls invoiceRepository.findOpenInvoicesForAccount(...).
