Evaluation
AI-evaluated 2026-09-03: Reasonable five-step outline with usage examples and data tips, but stays generic: no concrete metric definitions, code, or output template, and defers all analysis to ad-hoc Python. Retention analysis is a common PM need with no setup, and the workflow is read-only local analysis.
