Audit an existing spreadsheet or financial model for correctness defects: live formula errors, broken or deleted references, hardcoded values inside formulas, off-by-one and inconsistent aggregate ranges, totals that do not reconcile or cross-foot, circular references, hidden rows/columns/sheets affecting outputs, and data-hygiene risks like numbers stored as text. Use when the user asks to review, check, validate, audit, debug, or find errors in an .xlsx, .xlsm, or .csv they already have. Produces a severity-ranked findings report and optional annotated copy. Do not use when the user wants to create, build, format, or rewrite a spreadsheet.
