This is a structured consulting framework that walks you through McKinsey-style problem solving, from issue trees and MECE decomposition to generating slide decks with real data. It's built around an 8-step workflow that breaks down business questions, forms hypotheses, designs dummy pages with specific layouts (it knows seven McKinsey page types), then generates each slide with web search, Excel data collection, and PPT output. The architecture is smart about context: it loads methodology docs only when needed and processes pages one at a time to avoid blowing up token usage. Version 4.0 integrates an iterative refinement system for higher quality outputs. Use this when you want consultant-grade deliverables without spending 90 hours doing the grunt work yourself.
