Repeatability
High
Exception handling refactors in Spring Boot follow well-established patterns (ControllerAdvice, ErrorResponse DTOs, MockMvc tests) that AI has seen thousands of times. The structural approach is nearly identical across projects, favoring automation.
Ambiguity Tolerance
High
Success criteria are concrete and verifiable: structured JSON with field name, error code, and message; integration tests that cover all validation paths and pass. A non-human can confirm both mechanically.
Data & Tool Availability
Medium
The agent needs full read access to the existing codebase, including the validation rule chain, current exception classes, and build configuration. Without this context, generated code risks missing existing validators or breaking existing behavior.
Error Cost
Low
This is a refactor with integration tests as a built-in safety net; mistakes surface immediately in CI and are easily reverted via version control. No production data or irreversible state is at risk.
Human Judgment Required
Low
Error code naming conventions and message wording may benefit from a quick human review for consistency with existing API contracts, but the structural decisions are well-defined enough that AI can make defensible choices without human taste or intuition.
