What problem does it solve? When building a workbook, PowerPoint deck, or executive report from messy or conflicting source files, AI-generated outputs often blend contradictory numbers, hide assumptions, and present guesses as facts. This Skill forces a structured preparation step that separates facts, assumptions, estimates, and conflicts before any file is created. ## Core Features & Use Cases - Source Inventory: Catalogs every source with type, date, owner, status, limitations, and what it can or cannot support. - Fact/Assumption/Estimate Split: Separates verified facts from assumptions, placeholders, interpretations, and open questions so nothing unsupported slips into the final file. - Conflict Log: Records where sources disagree on numbers, dates, or decisions, and flags which conflicts need a human ruling. - File Specification & Human-Review Gate: Produces a tab map or slide outline with claim-level source IDs, then lists the decisions a human must make before file creation begins. - Use Case: Before asking AI to build a quarterly board deck from a folder of spreadsheets, exports, and meeting notes, run this Skill to get a source inventory, conflict log, and slide spec with evidence requirements. ## Quick Start Use the office-file-truth-setup skill to prepare a verified truth layer from the attached source folder before creating my executive report.
