| description | Use when you have an approved PRD and need to break it into actionable user stories for development. |
Break an approved PRD into actionable user stories organized into epics. Each story must satisfy INVEST criteria and include Gherkin-format acceptance criteria with edge cases and error states.
Announce at start: "I'm using the user-story-writing skill to break the PRD into user stories."
Do NOT invoke this skill unless the PRD is approved. If the PRD hasn't been written, invoke writing-prd after product-discovery.Save stories to: docs/product-superpowers/stories/YYYY-MM-DD-<feature-name>-stories.md
You MUST create a task for each of these items and complete them in order:
Re-read the approved PRD. Note:
Group related user stories into epics. An epic represents a large body of work that delivers a coherent user outcome.
Epic guidelines:
Example epic structure:
Epic: New User Onboarding
└── Story: Sign up with email
└── Story: Sign up with Google SSO
└── Story: Complete profile setup
└── Story: Guided product tour
└── Story: Skip onboarding entirely
Epic: Core Dashboard
└── Story: View key metrics at a glance
└── Story: Filter dashboard by date range
└── Story: Export dashboard as PDF
└── Story: Customize dashboard layout
Use the standard format:
As a [specific user persona]
I want to [goal or desire]
So that [reason or benefit]
Persona-driven, not role-driven:
Goal-focused, not feature-focused:
Benefits that connect to outcomes:
Verify every story meets all INVEST criteria:
| Criterion | Check | Red Flag |
|---|---|---|
| Independent | Can this story be developed independently? | "Depends on [other story] being complete" |
| Negotiable | Can details be adjusted during development? | Over-prescribed implementation details |
| Valuable | Does this deliver value to users or the business? | Pure technical stories with no user benefit |
| Estimable | Can the team roughly estimate the effort? | "We don't know enough to estimate" (needs spike) |
| Small | Can it be completed in one sprint? | "This will take the whole team the entire sprint" (too large, split it) |
| Testable | Is there a clear pass/fail condition? | "The user should have a good experience" (vague) |
Stories that fail INVEST must be rewritten, split, or marked as spikes.
For each story, write acceptance criteria in Given-When-Then format:
Given [precondition or context]
When [action or event]
Then [expected outcome]
Examples:
Story: Sign up with email
Given I am on the sign-up page
When I enter a valid email and password and click "Create Account"
Then I am redirected to the dashboard
And I receive a welcome email
And my account is created in the database
Given I am on the sign-up page
When I enter an email that is already registered and click "Create Account"
Then I see the error message "An account with this email already exists"
And I am shown a link to "Sign in instead"
Given I am on the sign-up page
When I enter an invalid email format and click "Create Account"
Then I see the error message "Please enter a valid email address"
And the form is not submitted
Given I am on the sign-up page
When I enter a password shorter than 8 characters and click "Create Account"
Then I see the error message "Password must be at least 8 characters"
And the password field is highlighted
Given I am on the sign-up page
When I click "Create Account" with all fields empty
Then I see validation errors on all required fields
And the form is not submitted
Acceptance criteria best practices:
For every user-facing story, document:
Before a story enters a sprint, it must be:
