Quick Review

Excellent spreadsheet skill with comprehensive task knowledge covering creation, editing, analysis, and formula recalculation. The description clearly identifies 5 specific use cases, making it easy for a CLI agent to invoke. Structure is logical with well-organized sections (Requirements, Workflows, Best Practices). Provides detailed financial modeling standards (color coding, formatting, documentation) and critical guidance on using formulas vs hardcoded values. The recalc.py script for formula verification adds significant value beyond basic Python libraries. Novelty is strong - financial modeling conventions, formula error prevention, and automated recalculation would require substantial tokens for a CLI agent to implement reliably. Minor improvement possible in making the description even more concise, but overall this is a production-ready, high-value skill.
