Quick Review

Excellent comprehensive spreadsheet skill with detailed task knowledge covering creation, editing, analysis, and formula recalculation. The description clearly explains when to invoke the skill (5 specific use cases). Structure is very good with logical sections, though SKILL.md is lengthy due to important financial modeling standards and best practices. The skill provides substantial value by combining openpyxl/pandas workflows with automated formula recalculation (recalc.py), error detection, and professional financial modeling standards that would require significant tokens for a CLI agent to reproduce consistently. Minor verbosity in structure is justified by the comprehensiveness of guidance.
