Repeatability
High
Every transformation rule is deterministic and applies uniformly across all rows — trim spaces, lowercase emails, split names on space, parse date formats, normalize status strings. This is structurally identical work repeated 22,000 times, which is exactly where agents excel.
Ambiguity Tolerance
High
The desired output format is fully specified: lowercase trimmed email, split first/last name columns, ISO-8601 dates, normalized status. Success is objectively verifiable by checking output column formats and value distributions, leaving almost no room for interpretation.
Data & Tool Availability
High
The agent needs only the CSV file and a Python or pandas environment — both trivially available. No external APIs, credentials, or live system access are required; the task is entirely self-contained.
Error Cost
Low
The original CSV is preserved and the output is a new file, so no data is destroyed. Errors are reversible and easily caught by spot-checking a sample of rows before importing back into Mailchimp.
Human Judgment Required
Low
The only judgment calls are edge cases like names with three parts (e.g., 'Mary Jo Smith') or ambiguous dates like '01/02/03', but these affect a tiny fraction of rows and can be flagged for human review rather than silently guessed.
