Explains the movement between two periods or between plan and actual in the open workbook by splitting it into the drivers the data supports, reconciling the named drivers back to the total, and reporting the remainder as unexplained rather than attributing it. Invents no driver. Use when the user asks why a number moved, to bridge two periods, or to explain a variance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Variance explainer ## Purpose Explain a movement without inventing a reason for it. The skill decomposes the change between two columns into the drivers the workbook can actually evidence, re-adds those drivers back to the total movement, and states the remainder as unexplained. A bridge that reconciles to the penny with no unexplained line is usually a bridge that has been forced. ## When to use - The user asks why a figure moved, to bridge two periods, or to explain plan against actual. - A variance needs a written explanation for a pack, a review or a meeting. - Do not use to decide which driver matters most commercially. This skill decomposes, the user interprets. ## Inputs 1. The open workbook (required), and the two columns or ranges being compared, with which is the base and which is the comparison. 2. Driver data (optional): the dimensions available to split by, such as volume, price, mix, rate, currency, entity or product. 3. Materiality (optional): the threshold below which a driver is grouped into Other. Default is one per cent of the total movement. ## Procedure …

How to install
mdr add kesslernity/awesome-copilot-office-skills/variance-explainer@sha256:1ef9a31c346c4393The line at the top of this page pins the label git:20261024.a411dc2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
