Quick Review

Excellent spreadsheet skill with comprehensive coverage of Excel operations. The description clearly identifies five key use cases (creation, reading, modification, analysis, recalculation). Task knowledge is outstanding with detailed workflows for pandas and openpyxl, formula best practices, financial modeling standards, and a formula recalculation script. Structure is clear with logical sections, though the SKILL.md is lengthy due to extensive financial modeling guidelines. The skill provides high novelty by handling complex Excel operations (formula preservation, formatting, error detection) that would require significant tokens for a CLI agent to accomplish reliably. Minor improvement possible: the financial modeling section is extensive and could be referenced in a separate file for better modularity, though this doesn't significantly impact usability.
