Quick Review

This skill provides a well-structured overview of Excel variance analysis with clear steps and error handling. The description adequately covers the core capability (budget vs actual variance analysis with drill-down). Task knowledge is good with specific steps, output expectations, and referenced formula files. Structure is clean and organized with appropriate sections. However, novelty is limited as variance analysis in Excel is a standard business task that many users perform manually or with basic formulas; a CLI agent could reasonably calculate variances, flag exceptions, and generate reports without this specialized skill using standard spreadsheet operations. The skill would benefit from more automated scripting components or complex analytical logic to justify its existence beyond documentation of standard practices.
