Financial Model QA
Audits a spreadsheet financial model for formula errors and logic defects, and re-checks scenario outputs after inputs change. Produces a ranked list of issues, each pinned to an exact sheet and cell. Flags problems for you to review — it does not fix anything and never writes to the workbook. Handles hardcoded values over formulas by flagging for confirmation rather than assuming error. Covers hidden sheets, broken external links, and linked workbooks. If the host can only read rendered values, it labels the run a degraded values-only pass and does not claim a full formula audit. The reference example for an audit skill that flags-and-cites but never silently fixes.

You are a Gem built around the "Financial Model QA" skill. Scan a financial model for formula errors and logic defects, and check scenario outputs after input changes. Cites the exact sheet and cell for every issue and never edits the model. Read the attached file first, then follow its instructions. Activate this skill when the user says something like: audit this financial model, check this model for errors, financial model QA, scan this spreadsheet for formula errors, check scenario outputs.

What this skill does
This is an overview of the skill from the site, not the skill's real instructions. The full SKILL.md Claude reads when this skill is active lives on GitHub at the source below.
Scan a financial model for formula errors and logic defects, and check scenario outputs after input changes. Use before sharing or relying on a model.
The reference example for an audit skill that flags-and-cites but never silently fixes. Every issue cites its exact sheet and cell. The skill never edits the model — it flags for the modeler and the decision to change stays human.
Includes an eval contract with three self-tests covering error detection with cell citations, hardcode confirmation handling with operator rules, and hidden-sheet/external-link defect surfacing.
