A scenario planning skill for Claude, ChatGPT, Gemini or Copilot. Give it a decision and your own numbers and it builds best, base, worst and stress-test cases for revenue, costs and cash: a driver table, consistent scenario narratives, a monthly or quarterly what-if model with formulas you can rebuild in Excel or Google Sheets, cash runway per scenario, breaking points, decision triggers with thresholds and the no-regret moves that work in every case.
For founders, finance leads, consultants and managers who need a downside case for the board, a lender or their own peace of mind. It never invents your figures or market data; gaps become placeholders. Unlike Bruno - Cash Flow Analyst, who builds the cash forecast itself, or the Business & Operations Prompt Library, a broad set of operations prompts, this skill does one job: turn a plan into scenarios with triggers and pre-agreed actions.
Turns a plan and your numbers into best, base and worst case scenarios with triggers and actions.
Compatible with: Claude, Claude Code, ChatGPT, Gemini and Copilot. Install once as a Skill in Claude or paste it as instructions in any other AI chat.
-
Is this a spreadsheet template? No - it is an AI skill; it builds the model in chat and gives formulas and a cell map to rebuild it in Excel or Sheets.
-
Will it make up market data? No - every driver value comes from you or is marked FIGURE NEEDED; no invented benchmarks.
-
What scenarios does it build? Base, upside, downside and an optional severe stress test, or a 2x2 matrix of your two biggest uncertainties.
-
Does it tell me what to do? It ties each scenario to triggers and contingency actions, and frames the plan as holds unless a trigger fires.
