Repeatability
High
The structure is nearly identical each cycle: ingest CSVs, normalize schemas, calculate fixed formulas (CPA = spend/conversions, ROAS = revenue/spend, CTR = clicks/impressions), and flag rule-based anomalies. Once the pipeline is built, re-running it on new exports is trivial.
Ambiguity Tolerance
High
Success criteria are concrete and verifiable: unified table with correct metrics, anomaly flags, and pivot-ready structure. The formulas are industry-standard and leave little room for interpretation.
Data & Tool Availability
High
The user has the CSVs in hand at 8–12 MB, well within file-handling limits. A code agent with Python (pandas) or a data tool can process everything locally without needing live API access or external permissions.
Error Cost
Medium
Miscalculated metrics or missed anomalies could lead to flawed client reporting, which carries reputational risk. However, the output is a spreadsheet reviewed before client delivery, making errors catchable and reversible before real damage occurs.
Human Judgment Required
Low
The task is almost entirely mechanical: schema mapping, arithmetic, and threshold-based flagging. The only judgment call is defining anomaly thresholds (e.g., what counts as a 'spend spike'), which the user can specify upfront.
