Repeatability
High
The task is a standard software engineering pattern: replace a crash-prone parser with a streaming, fault-tolerant one and add a CLI flag. The structure is the same every time this class of problem appears, with no unique judgment required per instance.
Ambiguity Tolerance
High
Success criteria are concrete and testable: no crashes on malformed rows, error reports include file/line/column/rule, streaming handles 500 MB files, and a --dry-run flag exists. An agent can verify all of these without human interpretation.
Data & Tool Availability
Medium
The agent needs access to the existing codebase, the regex validation rules, and sample CSV files including malformed ones. If the repo and test data are provided, the agent has everything it needs; if not, it must make assumptions about the existing structure.
Error Cost
Medium
A buggy rewrite could silently misparse valid rows or fail to catch errors, corrupting downstream data pipelines. However, the task is reversible via version control, and a dry-run flag is itself a safety mechanism that reduces production risk.
Human Judgment Required
Low
The engineering decisions here — buffered I/O, error accumulation, structured error types in Go — are well-established patterns with no meaningful taste or ethics dimension. A human review pass before merging is prudent but not strictly required for the generation step.
