Hire an AI business plan downside and failure-scenario reviewer

Share your business plan, assumptions and resource limits.

What you give

  • The business plan, however rough
  • The numbers behind it: costs, prices, how many customers and when
  • What you are putting in: money, time, what you give up

What you get

  • The strongest case for killing the idea
  • Each assumption stress tested at half as good and twice as slow, and a ruin-risk check
  • A pre-mortem: the most likely story of failure and what to change now

An example

You are about to sign a lease, hire or spend savings on a plan.

You ask: “Share your business plan, assumptions and resource limits. Use the material I attach and ask for anything essential that is missing.”

You get back:

  • One-page canvas. Problem, customers, solution, channels, revenue, costs and advantage, with every assumption marked.
  • The case against. The strongest honest case for not doing this, with the fatal flaw if there is one, rivals and why customers will not switch.
  • Stress tests. Each assumption tested at half as good and twice as slow, and which ones the plan cannot survive.

An example, not your task.

Details

Everything it can hand back

Your task sets the actual outputs. The specialist picks the methods that cover them.

  • A one-page canvas with every assumption visible
  • The strongest case for killing the idea
  • Each assumption stress tested at half as good and twice as slow, and a ruin-risk check
  • A pre-mortem: the most likely story of failure and what to change now

How it does the job well

  • Start from the user problem and the evidence for it, then the solution.
  • Write decisions down with the reason and the options you rejected.
  • Keep scope small enough to ship and learn. Name what is out of scope.
  • Define how success will be measured before building.

Mistakes it avoids

  • Treating opinions or one loud request as proven demand.
  • Specs that skip edge cases, error states or dependencies.
  • Roadmaps with dates but no owners or confidence levels.

What a good result looks like

An example, not your task: You are about to sign a lease, hire or spend savings on a plan.

  • One-page canvas. Problem, customers, solution, channels, revenue, costs and advantage, with every assumption marked.
  • The case against. The strongest honest case for not doing this, with the fatal flaw if there is one, rivals and why customers will not switch.
  • Stress tests. Each assumption tested at half as good and twice as slow, and which ones the plan cannot survive.
  • Ruin check. The risks you cannot recover from, how exposed you are, and how to cap the downside.
  • Pre-mortem. The most likely story of how the plan failed a year on, and what to change today.
  • HAND-BACK SUMMARY. Each step's file, any step not run and why, and every MISSING line in one list.

How the work is checked

  • Each step passed its own checks, or the run stopped at the step that failed and says why.
  • The steps ran in order, and each one used the result of the one before.
  • Nothing was invented to fill a gap. Every gap is a MISSING: line.
  • Nothing was sent, published or paid for without a clear yes.
  • States which checks passed, failed or could not run, and names missing inputs.

These checks have not been run against a model yet. Your AI uses them to check its own work.

A second opinion

Before it hands back, your AI reviews the draft the way Nassim Nicholas Taleb would. This is a way of reviewing the work. It does not mean they wrote or endorse it.

Capabilities

  • Squeeze it onto one page. Puts the plan on a one-page canvas with every assumption marked.
  • Argue for killing it. Writes the strongest honest case for not doing this.
  • Stress test the assumptions. Tests each assumption at half as good and twice as slow and says which the plan cannot survive.
  • Check for ruin. Finds the risks you cannot recover from, in Taleb's manner, and says how to cap the downside.
  • Run the pre-mortem. Imagines the plan has failed a year from now, writes the most likely story of why, and says what to change now.

How the role works

  1. Checks your task, context and available tools.
  2. Picks the methods needed and prepares a work plan.
  3. Carries out supported tasks, with each method's limits and review gates.
  4. Checks the real deliverables and corrects supported faults.
  5. Hands back files, evidence and unresolved gaps.

Inputs and helpful context

The specialist starts from the task brief. Only active methods require their inputs.

For the primary method, when used

  • The business plan, however rough
  • The numbers behind it: costs, prices, how many customers and when
  • What you are putting in: money, time, what you give up
  • What you fear most (optional)

Helpful context (optional)

  • Your forecast spreadsheet with its inputs
  • Contracts with penalties or guarantees
  • How a past plan of yours failed

Tools and access

  • Any good chat AI: Every step is a plan or a piece of writing.
  • A spreadsheet: Change the inputs and watch the plan break or hold.
  • Any good chat AI: Listing dependencies and testing plans in text is what any strong chat AI does with this skill.
  • A spreadsheet: Handy for putting fixed costs, cash and exposure side by side.

Tasks you can use it for

  • You are about to sign a lease, hire or spend savings on a plan.
  • Everyone around you likes the plan, which worries you.
  • A past plan failed for a reason that was obvious afterwards.

Limits to check before starting

  • You have no money, lease or guarantee at stake yet: run a simple test with a few real customers first.
  • You only want to check one number, such as break-even in a bad year: use the Bad-year break-even tester.
  • You want to know if the idea suits AI rather than whether the business works: use the AI suitability reviewer.

Best way to use this role

Give it one clear outcome, the actual files and a definition of done. Keep the work in one AI project so it can reuse checked context and earlier files.

  • Download the handoff pack. It has HANDOFF.md and five skill files, in the order they run: Lean canvas builder, Business idea killer, Business assumption stress tester, Ruin risk stress tester and Plan pre-mortem runner.
  • Give the folder to Claude (in Claude Code, or as files in a Claude Project) and say "Follow HANDOFF.md".
  • Paste the plan and the numbers. It writes the canvas and the case against.
  • Read the stress tests and the ruin risks. Decide which you can remove.
  • Read the pre-mortem. Change the plan so that story cannot happen, or decide not to go.
