State your business question and the skill runs an 8-step workflow: problem definition, MECE issue tree, hypothesis formation, dummy page design, then page-by-page data collection and slide generation. The full process takes about 90-110 minutes and yields a 15-25 page deck.

A dummy page is a detailed slide plan specifying the argument-style title, layout type, chart type, exact data needs, and sources before any data is collected. This skill generates a complete Dummy.md file so slides can be produced consistently, even across separate conversations.

Yes. Upload the Dummy.md file plus any completed PPT and Excel files, and specify which page to continue from. Each page carries dependency annotations so the skill checks prerequisites before generating.

Yes. Every quantitative data point is recorded in an Excel workbook with source URLs, collection dates, quality grades, and confidence levels. Key figures are cross-validated across two to three sources, and estimates are explicitly labeled with their calculation method.

This happens when text color is not forced to white on dark blue backgrounds. The skill enforces a rule that any primary or secondary blue background must use white text, and runs a post-generation check to fix violations.

Data quality depends on publicly available web sources, so proprietary market data may be missing and recent figures may rely on estimates. Very large decks beyond roughly 25 pages may still strain context, and the output requires user review rounds to reach final quality.
