Repeatability
High
Refactoring for efficiency and adding error handling follows well-established patterns in Python. The structural approach is consistent across instances, even if the specific function varies.
Ambiguity Tolerance
Medium
The core requirements — efficiency and error handling for missing columns and malformed data — are reasonably crisp, but 'more efficient' leaves room for interpretation (memory, speed, readability). A human review pass is advisable to confirm the refactor meets intent.
Data & Tool Availability
High
The agent needs the source function and ideally sample CSV files; both are straightforward to provide. No external APIs or special permissions are required.
Error Cost
Low
Code changes are easily reversible via version control, and the refactored output can be reviewed and tested before deployment. The risk of real damage is low.
Human Judgment Required
Low
Standard Python refactoring patterns and error-handling idioms are well within current AI capability. Human review is good practice but not strictly required for correctness.
