Quick Review

Excellent spreadsheet processing skill with comprehensive coverage of Excel/CSV operations. The description clearly communicates capabilities (create/edit with formulas/formatting, analyze data, visualization, recalculate formulas). Task knowledge is strong with detailed code examples for pandas and openpyxl, formula recalculation workflow, error handling checklist, and financial modeling standards. Structure is well-organized with clear sections, though slightly dense in places. The skill provides meaningful value through automated formula recalculation (recalc.py), zero-error validation, and industry-standard financial modeling conventions that would be token-intensive for a CLI agent to replicate. Minor deductions: structure could be more concise in the financial standards section, and while useful, spreadsheet manipulation is moderately novel rather than highly complex. The mandatory formula recalculation workflow and comprehensive error detection add significant practical value.
