Repeatability
High
The transformation rules are fully deterministic: keep the most recent record per email, standardize dates to ISO 8601, flag malformed emails. This structure is identical every run and requires no per-record judgment calls beyond the defined rules.
Ambiguity Tolerance
High
Success criteria are crisp and verifiable: zero duplicate emails in the clean file, all dates in ISO 8601, malformed emails isolated to a separate file. A script or agent can self-validate all three conditions programmatically.
Data & Tool Availability
High
The input is a self-contained JSON export — no live API calls, credentials, or external context needed. The agent only needs the file and a Python or similar runtime to produce the two output CSVs.
Error Cost
Low
The output is a CSV file reviewed before import into HubSpot, not a live system action. Errors are catchable at review time, and the original JSON export is untouched, making this fully reversible.
Human Judgment Required
Low
The deduplication rule (keep most recent by last-login timestamp) is explicit, removing the need for case-by-case human calls. Edge cases — truly ambiguous duplicates or unparseable dates — are correctly routed to the flagged file for human review.
