I would have a PR-level rule like:

Review this integration change against:

1. approved business rules
2. field mapping
3. API/event contract
4. idempotency requirements
5. Salesforce limits/relationships
6. null semantics
7. error/retry design
8. security/logging rules
9. existing regression coverage

Flag:
- undocumented behavior
- broken traceability
- missing test coverage
- accidental target-field changes

This is much better than generic:

“Review my code.”
