Hire an AI risky business assumption test planner

Share your plan and key uncertainties. Get measurable assumptions, a small test for the riskiest one and decision rules set before testing.

What you give

  • Your plan (what you make, for whom, how they find it and what you expect back)
  • What you can spend and who you can reach this week (optional)

What you get

  • The guesses your plan rests on, each with a number, ranked, with the riskiest named
  • The cheapest kind of test for the top guess, who to try it on and what to leave out
  • Pass, fail and in-between numbers set before the run
  • A run plan and a rule for what to do on a pass, a fail or a middle result

An example

You have a plan and sense that part of it is a bet, but cannot say which part.

You ask: “Share your plan and key uncertainties. Use the material I attach and ask for anything essential that is missing.”

You get back:

  • step-01-leap-of-faith-assumption-finder.md. The few guesses your plan rests on, each with a predicted number, ranked with the riskiest first.
  • step-02-smallest-test-picker.md. The cheapest kind of test for the top guess, who to try it on and what to leave out.
  • step-03-mvp-experiment-planner.md. Pass, fail and in-between numbers set before the run, a run plan and a rule for what to do next.

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.

  • The guesses your plan rests on, each with a number, ranked, with the riskiest named
  • The cheapest kind of test for the top guess, who to try it on and what to leave out
  • Pass, fail and in-between numbers set before the run
  • A run plan and a rule for what to do on a pass, a fail or a middle result

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 have a plan and sense that part of it is a bet, but cannot say which part.

  • step-01-leap-of-faith-assumption-finder.md. The few guesses your plan rests on, each with a predicted number, ranked with the riskiest first.
  • step-02-smallest-test-picker.md. The cheapest kind of test for the top guess, who to try it on and what to leave out.
  • step-03-mvp-experiment-planner.md. Pass, fail and in-between numbers set before the run, a run plan and a rule for what to do next.
  • 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 Eric Ries and Steve Blank would. This is a way of reviewing the work. It does not mean they wrote or endorse it.

Capabilities

  • Finds the guesses. Rewrites comparisons as plain facts, splits the plan into a value guess and a growth guess, adds a number to each and ranks them.
  • Picks the smallest test. Names the behaviour that counts as yes, picks the cheapest test form, chooses early adopters and cuts everything that does not feed the answer.
  • Sets the numbers and the next move. Writes pass, fail and middle numbers first, plans the run one group at a time and writes what to do on each result.

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.

Your specialist's working setup

Download the base specialist without a task form or account. README.md and SETUP.md explain how to use the folder. SOUL.md defines its scope. INTAKE.md asks missing questions inside your AI. PLAYBOOK.md, SKILLS.md, BEST_PRACTICES.md, CHECKS.md and HANDOFF.md guide the work and its checked deliverables.

Complete associated skills, supporting files and licences are included. Choose only the methods needed for the actual task. Keep context, working files and accepted feedback in your AI project.

Tasks you can use it for

  • You have a plan and sense that part of it is a bet, but cannot say which part.
  • You are about to spend months building and want proof of the shakiest part first.
  • Your last test left you with praise and no facts.

Limits to check before starting

  • Your plan already has sales or usage data behind it: test the change directly with your own numbers, or use the Ad meaning test planner if the doubt is about an ad.
  • You still need to learn what buyers worry about: use the Buyer problem list builder, or talk to five customers first.
  • You need to find where your buyers gather online: use the Customer community finder.

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 pack. It holds HANDOFF.md and three skill files, in the order they run: Leap-of-faith assumption finder, Smallest test picker, then MVP experiment planner.
  • Give the folder to Claude (in Claude Code, or as files in a Claude Project) and say "Follow HANDOFF.md".
  • Paste your plan as it stands, comparisons and all. Add the numbers you have, such as price, reach and sign-up rate. Say what worries you most.
  • Any number your plan does not give is marked GUESS. Check each GUESS before you rely on it.
  • Agree the pass numbers before you run the test, then bring back the results. This workflow plans the test. It does not run it.
