Quick Review

High-quality spreadsheet skill with comprehensive coverage of Excel operations. The description clearly conveys capabilities (creation, editing, analysis, formulas, formatting), enabling a CLI agent to invoke appropriately. Task knowledge is excellent with detailed workflows for pandas/openpyxl, formula construction rules, financial modeling standards, and error prevention strategies. Structure is logical with clear sections, though slightly dense in places. Novelty is moderate-to-good: while pandas/openpyxl are standard libraries, the skill adds significant value through the recalc.py script for formula evaluation, comprehensive financial modeling conventions (color coding, number formatting), and systematic error prevention workflows that would otherwise require many agent tokens to replicate correctly.
