What it does

When you ask the agent to stress-test a business assumption, it follows a structured method: it states the assumption precisely, looks for evidence that it is wrong, models downside scenarios (such as a 30%, 50% or 80% shortfall), measures how sensitive the outcome is to that one variable, and proposes hedges like a validation experiment, a fallback plan, or an early warning indicator. It also provides specific question sets for revenue, market size, competitive moat, hiring and competitive response. The skill is a written method and checklist; it does not include scripts or external data.

Great for

  • Founders or executives about to commit budget to a plan built on unvalidated assumptions
  • Teams reviewing a revenue model, hiring plan or market-size claim before a board or investor meeting
  • Anyone who wants a structured devil's-advocate review of a business case

Skip it if

  • Final financial, legal or investment decisions: the skill gives a framework and questions, not verified market data, and its output is only as good as the inputs you provide
  • Situations needing real market research: it instructs the agent to search for counter-evidence, but the files do not connect it to any data source, so results depend on what the agent already knows or what you supply

Try asking

  • “/em:stress-test enterprise buyers will tolerate a 6-month pilot before signing”
  • “/em:stress-test our hockey-stick model reaching $2M ARR by December”
  • “/em:stress-test the $50M TAM for our product by building a bottoms-up account list”
  • “/em:stress-test our plan if the VP Sales hire takes 5 months instead of 2”

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • State the assumption with specific numbers and a time frame; vague claims cannot be tested, as the skill itself notes.
  • Provide your real historical data (win rates, churn, CAC) so the downside scenarios are grounded rather than guessed.
  • Treat the output as a list of questions to investigate, and verify any market figures the agent cites independently.
