How to use this method

  1. 1. Copy or downloadCopy the prompt below, or download the method file and attach it to your chat.
  2. 2. Paste into any AIChatGPT, Claude, Gemini or Copilot. Replace each [PLACEHOLDER] with your details, or let the AI ask you.
  3. 3. Add evidenceAttach the evidence files listed on this page so the AI works from sourced numbers, not guesses.

The prompt

Paste it as-is. The AI will ask for anything still in [BRACKETS].

# Write user stories with acceptance criteria
Method by Deepstory Research: deepstoryresearch.com/method/user-stories-acceptance-criteria

You are an agile product owner. Follow the method below step by step. Goal: INVEST-quality user stories with Given/When/Then acceptance criteria and edge cases.

## My inputs
- Feature or PRD: [FEATURE_OR_PRD]  (example: paste)
- User roles: [USER_ROLES]  (example: admin, member, guest)

Before you start: if any input above is still in [BRACKETS] or missing, ask me for it in one short numbered list and wait. Do not guess. If I attached files (data, briefs, Deepstory evidence files), treat them as the primary source.

## Steps to follow
1. Split the feature into thin vertical stories.
2. Write each as "As a…, I want…, so that…".
3. Add Given/When/Then criteria including edge and error cases.
4. Estimate relative size and flag dependencies.

## Deliver the output in this structure
- Story list
- Acceptance criteria
- Edge cases
- Dependencies

## Quality rules
- Each story delivers user value on its own.
- Label every number as FACT (with source and date), ESTIMATE (show the calculation) or ASSUMPTION.
- If a Deepstory evidence file is attached, use its figures as the reference values and cite its source references; tag claims that are not from it as [UNVERIFIED].
- End with: the 3 assumptions that matter most, what would change the answer, and the single best next step.

The procedure, step by step

Read this before you run it, so you can check the AI actually followed the method.

  1. 1

    Split the feature into thin vertical stories.

  2. 2

    Write each as "As a…, I want…, so that…".

  3. 3

    Add Given/When/Then criteria including edge and error cases.

  4. 4

    Estimate relative size and flag dependencies.

Quality checks built into the prompt

  • • Each story delivers user value on its own.
  • • Every number labelled FACT, ESTIMATE or ASSUMPTION; claims outside attached evidence tagged [UNVERIFIED].
