Repeatability
High
This is a one-time refactor with a stable, well-understood problem pattern: batch inserts and encoding handling are solved problems in .NET. The structure of the task doesn't change between attempts, which is favorable for automation.
Ambiguity Tolerance
High
Success criteria are concrete and measurable: runtime under 2 minutes, no skipped rows with special characters, and batch insert usage. An agent can verify its own solution against these criteria without subjective judgment.
Data & Tool Availability
Medium
The agent needs the existing VB.NET source code, the SQL Server schema, and ideally sample CSV files with edge-case encodings. If these are provided, the agent has everything it needs; if not, it must make assumptions that could cause runtime failures.
Error Cost
Medium
A buggy import routine could silently corrupt or drop rows in a production database, which is a real but recoverable risk if backups exist and the change is tested in staging first. Deploying untested AI-generated code directly to production would be the actual error, not the code generation itself.
Human Judgment Required
Low
The technical decisions here — SqlBulkCopy vs. TVP, encoding detection strategy, transaction batching — are well-documented patterns with clear tradeoffs. No taste, ethics, or relationship context is needed; a human review of the output before deployment is sufficient.
