Repeatability
High
The structure is identical each time: ingest files, map fields, deduplicate on email, output a standardized CSV and quality report. This is a textbook repeatable ETL pattern that favors automation strongly.
Ambiguity Tolerance
High
Output columns are explicitly named, deduplication logic is defined (same email = same person), and the quality report requirement is concrete. Success is objectively verifiable by checking the output schema and row counts.
Data & Tool Availability
High
All three source files (CSV, JSON, Excel) are described as available and can be passed directly to a code-execution agent. No live API calls or authentication are required for this batch task.
Error Cost
Low
The output is a new CSV file, not a destructive operation on source data. Errors are easily caught by reviewing the quality report or spot-checking the merged output before any downstream use.
Human Judgment Required
Low
Field mapping and deduplication are rule-based. The only soft judgment is handling slightly different name spellings for the same email, which can be resolved algorithmically with a simple normalization rule and flagged for review rather than silently decided.
