cohort-analysis-creator

Quick Review

This skill is severely under-specified for cohort analysis. The description is circular and vague ('Create cohort analysis creator operations'), providing no detail about what cohort analysis entails (e.g., user retention over time, behavior segmentation by acquisition date). Task knowledge is essentially absent—there are no concrete steps, code examples, SQL patterns, or methodologies for building cohort tables, calculating retention rates, or visualizing cohorts. The structure is clear and well-organized with appropriate sections, but they contain only generic placeholder content. Novelty is limited because cohort analysis, while valuable, is a well-defined analytics pattern that a capable CLI agent could implement given proper documentation; this skill adds minimal value in its current form. To improve: add specific cohort analysis methodologies, SQL query templates for cohort creation, retention calculation formulas, and visualization examples.
