Repeatability
High
The logic is identical every run: check syntax, match against known domain typo patterns, run SMTP verification, score confidence, output CSV. No unique judgment is needed per address.
Ambiguity Tolerance
High
Success criteria are crisp: valid syntax, SMTP response codes, known-good domains, confidence scores, and a clean CSV output. The agent can definitively know when the task is done.
Data & Tool Availability
Medium
The input CSV is available, and libraries for syntax validation and domain fuzzy-matching exist. SMTP verification requires outbound network access and careful rate-limiting to avoid being flagged as a spammer, which is a real infrastructure dependency.
Error Cost
Low
The output is a staged CSV for human review before any email is sent, so a miscategorized address causes no direct harm. The worst case is a false positive or false negative that a human can catch on review.
Human Judgment Required
Low
Domain typo correction (gmial.com → gmail.com) is a well-solved fuzzy-matching problem. Confidence scoring is algorithmic. No taste, ethics, or relationship context is needed here.
