What problem does it solve? When a spreadsheet-backed analysis becomes a board deck, QBR, investor update, or client presentation, reviewers cannot verify whether each slide claim is supported by real data. This Skill builds a traceable evidence map linking every slide claim back to workbook tabs, cell ranges, source files, assumptions, and review status. ## Core Features & Use Cases - Claim-to-Source Mapping: For each slide, record the claim headline, workbook tabs, cell ranges or named outputs, source file IDs, calculations, assumptions, date range, owner, and review status (verified / needs review / unsupported / conflicting). - Evidence Gap Review: Flag claims with no source, numbers with no date, charts with unclear data, assumptions presented as facts, stale or superseded sources, and conflicts requiring human judgment. - Use Case: Before presenting a QBR deck built from multiple Excel workbooks, run this workflow to produce a table showing exactly which cells and files back each slide, and to surface any unsupported or conflicting claims before the meeting. ## Quick Start Use the excel-to-deck-evidence-map skill to trace every claim in my board deck back to the supporting workbook tabs, cells, and source files, and flag any unsupported claims.
