Repeatability
High
Every step — date parsing, tag splitting, deduplication logic, duration calculation, CSV output — follows a fixed, deterministic rule. The same script can be re-run on new batches with no structural changes.
Ambiguity Tolerance
High
All transformation rules are explicitly stated: keep longest note on duplicates, split tags into rows, compute duration in hours. There is no subjective judgment required to know when the output is correct.
Data & Tool Availability
High
The input is a local JSON file the user already has. The agent needs only standard libraries (pandas, csv, datetime) and file access — no external APIs or credentials required.
Error Cost
Low
The source data is untouched; the output is a new CSV. Any mistake is immediately visible by spot-checking the output and is fully reversible by re-running the script.
Human Judgment Required
Low
The 'cleaned notes' field is the only loosely defined step, but standard text normalization (stripping HTML, collapsing whitespace, removing control characters) covers the vast majority of cases without human taste calls.
