explain-my-variance

What problem does it solve?

This Skill explains why a Profit & Loss (P&L) line moved by decomposing material changes into price, volume, mix, and one-time drivers grounded in your bookkeeping evidence.

Core Features & Use Cases

• Variance decomposition with evidence: Breaks each material line change into price, volume, mix, and one-time drivers tied to specific journal entry IDs and transaction sets.
• Multi-baseline comparison: Compares actuals against budget (if available), prior period, and same period prior year.
• Residuals, not guesses: Surfaces unexplained residuals explicitly instead of quietly inventing causes.
• Narrative report for decision-making: Produces a 3–5 paragraph story highlighting the biggest movers rather than only a spreadsheet.

Quick Start

Use the explain-my-variance skill to analyze the P&L for March 2025 using your existing journal entries and any available budget file, and write a driver-backed 3–5 paragraph explanation of the largest swings.
