Repeatability
High
The transformation rules are structurally identical every time: deduplicate by URL keeping the latest timestamp, normalize category strings to a canonical set, flag NULLs. This is a repeatable pipeline, not a judgment call.
Ambiguity Tolerance
High
Success criteria are crisp and enumerable: zero duplicate URLs, consistent category labels, and a clearly flagged subset of rows with missing traffic_source. A non-human can verify all three programmatically.
Data & Tool Availability
High
The user has the CSV in hand and the column schema is fully described. A code-capable agent needs only file access and a Python/pandas environment, both of which are standard and readily available.
Error Cost
Low
The source CSV is untouched, so any mistake in the output is trivially reversible by re-running the script. No downstream system is being written to automatically, and the flagged rows go to manual review anyway.
Human Judgment Required
Low
The only mild judgment call is mapping variant category names to a canonical label (e.g., 'SEO' vs 'Search Engine'), but the user can supply a mapping table or the agent can propose one for a quick human sign-off before writing output.
