Quick Review

Excellent spreadsheet processing skill with comprehensive coverage of Excel/CSV operations. The description clearly conveys capabilities (create/edit, formulas, formatting, analysis, recalculation). Task knowledge is extensive, covering openpyxl and pandas workflows, formula recalculation via recalc.py, error checking, and financial modeling best practices with detailed color-coding and formatting standards. Structure is well-organized with clear sections, though slightly lengthy for SKILL.md (could move some detailed financial standards to separate docs). Novelty is moderate - while pandas/openpyxl are standard libraries, the integrated formula recalculation system with LibreOffice, automated error detection/reporting, and financial modeling conventions add meaningful value beyond basic CLI operations. The skill would save tokens and reduce errors for complex spreadsheet tasks, especially financial models requiring zero-error deliverables.
